                           INDEMNIFICATION AGREEMENT



               THIS AGREEMENT (the 'Agreement') is made and entered into as of
March __, 1999, between REDBACK NETWORKS INC., a Delaware corporation ('the
Company'), and ________________ ('Indemnitee').

               WITNESSETH THAT:

               WHEREAS, Indemnitee performs a valuable service for the Company;
and

               WHEREAS, the Board of Directors of the Company has adopted Bylaws
(the 'Bylaws') providing for the indemnification of the officers and directors
of the Company to the maximum extent authorized by Section 145 of the Delaware
General Corporation Law, as amended ('Law'); and

               WHEREAS, the Bylaws and the Law, by their nonexclusive nature,
permit contracts between the Company and the officers or directors of the
Company with respect to indemnification of such officers or directors; and

               WHEREAS, in accordance with the authorization as provided by the
Law, the Company may purchase and maintain a policy or policies of directors'
and officers' liability insurance ('D & O Insurance'), covering certain
liabilities which may be incurred by its officers or directors in the
performance of their obligations to the Company; and

               WHEREAS, in recognition of past services and in order to induce
Indemnitee to continue to serve as an officer or director of the Company, the
Company has determined and agreed to enter into this contract with Indemnitee;

               NOW, THEREFORE, in consideration of Indemnitee's service as an
officer or director after the date hereof, the parties hereto agree as follows:

               1. Indemnity of Indemnitee. The Company hereby agrees to hold
harmless and indemnify Indemnitee to the full extent authorized or permitted by
the provisions of the Law, as such may be amended from time to time, and Article
VII of the Bylaws, as such may be amended. In furtherance of the foregoing
indemnification, and without limiting the generality thereof:

                      (a) Proceedings Other Than Proceedings by or in the Right
of the Company. Indemnitee shall be entitled to the rights of indemnification
provided in this Section 1(a) if, by reason of his Corporate Status (as
hereinafter defined), he is, or is threatened to be made, a party to or
participant in any Proceeding (as hereinafter defined) other than a Proceeding
by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee
shall be indemnified against all Expenses (as hereinafter defined), judgments,
penalties, fines and amounts paid in settlement actually and reasonably incurred
by him or on his behalf in connection with such Proceeding or any claim, issue
or matter therein, 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 Proceeding, had no
reasonable cause to believe his conduct was unlawful.

                      (b) Proceedings by or in the Right of the Company.
Indemnitee shall be entitled to the rights of indemnification provided in this
Section 1(b) if, by reason of his Corporate Status, he is, or is threatened to
be made, a party to or participant in any Proceeding brought by or in the right
of the Company. Pursuant to this Section 1(b), Indemnitee shall be indemnified
against all Expenses actually and reasonably incurred by him or on his behalf in
connection with 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; provided, however, that, if applicable law so provides, no
indemnification against such Expenses shall be made in respect of any claim,
issue or matter in such Proceeding as to which Indemnitee shall have been
adjudged to be liable to the Company unless and to the extent that the Court of
Chancery of the State of Delaware shall determine that such indemnification may
be made.

                      (c) Indemnification for Expenses of a Party Who is Wholly
or Partly Successful. Notwithstanding any other provision of this Agreement, to
the extent that Indemnitee is, by reason of his Corporate Status, a party to and
is successful, on the merits or otherwise, in any Proceeding, he shall be
indemnified to the maximum extent permitted by law against all Expenses actually
and reasonably incurred by him or on his behalf in connection therewith. If
Indemnitee is not wholly successful in such Proceeding but is successful, on the
merits or otherwise, as to one or more but less than all claims, issues or
matters in such Proceeding, the Company shall indemnify Indemnitee against all
Expenses actually and reasonably incurred by him or on his behalf in connection
with each successfully resolved claim, issue or matter. For purposes of this
Section and without limitation, the termination of any claim, issue or matter in
such a Proceeding by dismissal, with or without prejudice, shall be deemed to be
a successful result as to such claim, issue or matter.

               2. Additional Indemnity. In addition to, and without regard to
any limitations on, the indemnification provided for in Section 1, the Company
shall and hereby does indemnify and hold harmless Indemnitee against all
Expenses, judgments, penalties, fines and amounts paid in settlement actually
and reasonably incurred by him or on his behalf if, by reason of his Corporate
Status, he is, or is threatened to be made, a party to or participant in any
Proceeding (including a Proceeding by or in the right of the Company),
including, without limitation, all liability arising out of the negligence or
active or passive wrongdoing of Indemnitee. The only limitation that shall exist
upon the Company's obligations pursuant to this Agreement shall be that the
Company shall not be obligated to make any payment to Indemnitee that is finally
determined (under the procedures, and subject to the presumptions, set forth in
Sections 6 and 7 hereof) to be unlawful under Delaware law.

               3.     Contribution in the Event of Joint Liability.

                      (a) Whether or not the indemnification provided in
Sections 1 and 2 hereof is available, in respect of any threatened, pending or
completed action, suit or proceeding


                                       2


in which Company is jointly liable with Indemnitee (or would be if joined in
such action, suit or proceeding), Company shall pay, in the first instance, the
entire amount of any judgment or settlement of such action, suit or proceeding
without requiring Indemnitee to contribute to such payment and Company hereby
waives and relinquishes any right of contribution it may have against
Indemnitee. Company shall not enter into any settlement of any action, suit or
proceeding in which Company is jointly liable with Indemnitee (or would be if
joined in such action, suit or proceeding) unless such settlement provides for a
full and final release of all claims asserted against Indemnitee.

                      (b) Without diminishing or impairing the obligations of
the Company set forth in the preceding subparagraph, if, for any reason,
Indemnitee shall elect or be required to pay all or any portion of any judgment
or settlement in any threatened, pending or completed action, suit or proceeding
in which Company is jointly liable with Indemnitee (or would be if joined in
such action, suit or proceeding), 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 Indemnitee in
proportion to the relative benefits received by the Company and all officers,
directors or employees of the Company other than Indemnitee who are jointly
liable with Indemnitee (or would be if joined in such action, suit or
proceeding), on the one hand, and Indemnitee, on the other hand, from the
transaction from which such action, suit or proceeding arose; provided, however,
that the proportion determined on the basis of relative benefit may, to the
extent necessary to conform to law, be further adjusted by reference to the
relative fault of Company and all officers, directors or employees of the
Company other than Indemnitee who are jointly liable with Indemnitee (or would
be if joined in such action, suit or proceeding), on the one hand, and
Indemnitee, on the other hand, in connection with the events that resulted in
such expenses, judgments, fines or settlement amounts, as well as any other
equitable considerations which the law may require to be considered. The
relative fault of Company and all officers, directors or employees of the
Company other than Indemnitee who are jointly liable with Indemnitee (or would
be if joined in such action, suit or proceeding), on the one hand, and
Indemnitee, on the other hand, shall be determined by reference to, among other
things, the degree to which their actions were motivated by intent to gain
personal profit or advantage, the degree to which their liability is primary or
secondary, and the degree to which their conduct is active or passive.

                      (c) Company hereby agrees to fully indemnify and hold
Indemnitee harmless from any claims of contribution which may be brought by
officers, directors or employees of the Company other than Indemnitee who may be
jointly liable with Indemnitee.

               4. Indemnification for Expenses of a Witness. Notwithstanding any
other provision of this Agreement, to the extent that Indemnitee is, by reason
of his Corporate Status, a witness in any Proceeding to which Indemnitee is not
a party, he shall be indemnified against all Expenses actually and reasonably
incurred by him or on his behalf in connection therewith.

               5. Advancement of Expenses. Notwithstanding any other provision
of this Agreement, the Company shall advance all Expenses incurred by or on
behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee's
Corporate Status within ten (10) days




                                       3


after the receipt by the Company of a statement or statements from Indemnitee
requesting such advance or advances from time to time, whether prior to or after
final disposition of such Proceeding. Such statement or statements shall
reasonably evidence the Expenses incurred by Indemnitee and shall include or be
preceded or accompanied by an undertaking by or on behalf of Indemnitee to repay
any Expenses advanced if it shall ultimately be determined that Indemnitee is
not entitled to be indemnified against such Expenses. Any advances and
undertakings to repay pursuant to this Section 5 shall be unsecured and interest
free. Notwithstanding the foregoing, the obligation of the Company to advance
Expenses pursuant to this Section 5 shall be subject to the condition that, if,
when and to the extent that the Company determines that Indemnitee would not be
permitted to be indemnified under applicable law, the Company shall be entitled
to be reimbursed, within thirty (30) days of such determination, by Indemnitee
(who hereby agrees to reimburse the Company) for all such amounts theretofore
paid; provided, however, that if Indemnitee has commenced or thereafter
commences legal proceedings in a court of competent jurisdiction to secure a
determination that Indemnitee should be indemnified under applicable law, any
determination made by the Company that Indemnitee would not be permitted to be
indemnified under applicable law shall not be binding and Indemnitee shall not
be required to reimburse the Company for any advance of Expenses until a final
judicial determination is made with respect thereto (as to which all rights of
appeal therefrom have been exhausted or lapsed).

               6. Procedures and Presumptions for Determination of Entitlement
to Indemnification. It is the intent of this Agreement to secure for Indemnitee
rights of indemnity that are as favorable as may be permitted under the law and
public policy of the State of Delaware. Accordingly, the parties agree that the
following procedures and presumptions shall apply in the event of any question
as to whether Indemnitee is entitled to indemnification under this Agreement:

                      (a) To obtain indemnification (including, but not limited
to, the advancement of Expenses and contribution by the Company) under this
Agreement, Indemnitee shall submit to the Company a written request, including
therein or therewith such documentation and information as is reasonably
available to Indemnitee and is reasonably necessary to determine whether and to
what extent Indemnitee is entitled to indemnification. The Secretary of the
Company shall, promptly upon receipt of such a request for indemnification,
advise the Board of Directors in writing that Indemnitee has requested
indemnification.

                      (b) Upon written request by Indemnitee for indemnification
pursuant to the first sentence of Section 6(a) hereof, a determination, if
required by applicable law, with respect to Indemnitee's entitlement thereto
shall be made in the specific case by one of the following three methods, which
shall be at the election of Indemnitee: (1) by a majority vote of the
disinterested directors, even though less than a quorum, or (2) by independent
legal counsel in a written opinion, or (3) by the stockholders.

                      (c) If the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section 6(b) hereof, the
Independent Counsel shall be selected as provided in this Section 6(c). The
Independent Counsel shall be selected by




                                       4


Indemnitee (unless Indemnitee shall request that such selection be made by the
Board of Directors). Indemnitee or the Company, as the case may be, may, within
10 days after such written notice of selection shall have been given, deliver to
the Company or to Indemnitee, as the case may be, a written objection to such
selection; provided, however, that such objection may be asserted only on the
ground that the Independent Counsel so selected does not meet the requirements
of 'Independent Counsel' as defined in Section 13 of this Agreement, and the
objection shall set forth with particularity the factual basis of such
assertion. Absent a proper and timely objection, the person so selected shall
act as Independent Counsel. If a written objection is made and substantiated,
the Independent Counsel selected may not serve as Independent Counsel unless and
until such objection is withdrawn or a court has determined that such objection
is without merit. If, within 20 days after submission by Indemnitee of a written
request for indemnification pursuant to Section 6(a) hereof, no Independent
Counsel shall have been selected and not objected to, either the Company or
Indemnitee may petition the Court of Chancery of the State of Delaware or other
court of competent jurisdiction for resolution of any objection which shall have
been made by the Company or Indemnitee to the other's selection of Independent
Counsel and/or for the appointment as Independent Counsel of a person selected
by the court or by such other person as the court shall designate, and the
person with respect to whom all objections are so resolved or the person so
appointed shall act as Independent Counsel under Section 6(b) hereof. The
Company shall pay any and all reasonable fees and expenses of Independent
Counsel incurred by such Independent Counsel in connection with acting pursuant
to Section 6(b) hereof, and the Company shall pay all reasonable fees and
expenses incident to the procedures of this Section 6(c), regardless of the
manner in which such Independent Counsel was selected or appointed.

                      (d) In making a determination with respect to entitlement
to indemnification hereunder, the person or persons or entity making such
determination shall presume that Indemnitee is entitled to indemnification under
this Agreement if Indemnitee has submitted a request for indemnification in
accordance with Section 6(a) of this Agreement. Anyone seeking to overcome this
presumption shall have the burden of proof and the burden of persuasion, by
clear and convincing evidence.

                      (e) Indemnitee shall be deemed to have acted in good faith
if Indemnitee's action is based on the records or books of account of the
Enterprise, including financial statements, or on information supplied to
Indemnitee by the officers of the Enterprise in the course of their duties, or
on the advice of legal counsel for the Enterprise or on information or records
given or reports made to the Enterprise by an independent certified public
accountant or by an appraiser or other expert selected with reasonable care by
the Enterprise. In addition, the knowledge and/or actions, or failure to act, of
any director, officer, agent or employee of the Enterprise shall not be imputed
to Indemnitee for purposes of determining the right to indemnification under
this Agreement. Whether or not the foregoing provisions of this Section 6(e) are
satisfied, it shall in any event be presumed that Indemnitee has at all times
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Company. Anyone seeking to overcome this
presumption shall have the burden of proof and the burden of persuasion, by
clear and convincing evidence.






                                       5


                      (f) If the person, persons or entity empowered or selected
under Section 6 to determine whether Indemnitee is entitled to indemnification
shall not have made a determination within thirty (30) days after receipt by the
Company of the request therefor, the requisite determination of entitlement to
indemnification shall be deemed to have been made and Indemnitee shall be
entitled to such indemnification, absent (i) a misstatement by Indemnitee of a
material fact, or an omission of a material fact necessary to make Indemnitee's
statement not materially misleading, in connection with the request for
indemnification, or (ii) a prohibition of such indemnification under applicable
law; provided, however, that such 30 day period may be extended for a reasonable
time, not to exceed an additional fifteen (15) days, if the person, persons or
entity making the determination with respect to entitlement to indemnification
in good faith requires such additional time for the obtaining or evaluating
documentation and/or information relating thereto; and provided, further, that
the foregoing provisions of this Section 6(g) shall not apply if the
determination of entitlement to indemnification is to be made by the
stockholders pursuant to Section 6(b) of this Agreement and if (A) within
fifteen (15) days after receipt by the Company of the request for such
determination the Board of Directors or the Disinterested Directors, if
appropriate, resolve to submit such determination to the stockholders for their
consideration at an annual meeting thereof to be held within seventy five (75)
days after such receipt and such determination is made thereat, or (B) a special
meeting of stockholders is called within fifteen (15) days after such receipt
for the purpose of making such determination, such meeting is held for such
purpose within sixty (60) days after having been so called and such
determination is made thereat.

                      (g) Indemnitee shall cooperate with the person, persons or
entity making such determination with respect to Indemnitee's entitlement to
indemnification, including providing to such person, persons or entity upon
reasonable advance request any documentation or information which is not
privileged or otherwise protected from disclosure and which is reasonably
available to Indemnitee and reasonably necessary to such determination. Any
Independent Counsel, member of the Board of Directors, or stockholder of the
Company shall act reasonably and in good faith in making a determination under
the Agreement of the Indemnitee's entitlement to indemnification. Any costs or
expenses (including attorneys' fees and disbursements) incurred by Indemnitee in
so cooperating with the person, persons or entity making such determination
shall be borne by the Company (irrespective of the determination as to
Indemnitee's entitlement to indemnification) and the Company hereby indemnifies
and agrees to hold Indemnitee harmless therefrom.

                      (h) The Company acknowledges that a settlement or other
disposition short of final judgment may be successful if it permits a party to
avoid expense, delay, distraction, disruption and uncertainty. In the event that
any action, claim or proceeding to which Indemnitee is a party is resolved in
any manner other than by adverse judgment against Indemnitee (including, without
limitation, settlement of such action, claim or proceeding with or without
payment of money or other consideration) it shall be presumed that Indemnitee
has been successful on the merits or otherwise in such action, suit or
proceeding. Anyone seeking to overcome this presumption shall have the burden of
proof and the burden of persuasion, by clear and convincing evidence.






                                       6


               7.     Remedies of Indemnitee.

                      (a) In the event that (i) a determination is made pursuant
to Section 6 of this Agreement that Indemnitee is not entitled to
indemnification under this Agreement, (ii) advancement of Expenses is not timely
made pursuant to Section 5 of this Agreement, (iii) no determination of
entitlement to indemnification shall have been made pursuant to Section 6(b) of
this Agreement within 90 days after receipt by the Company of the request for
indemnification, (iv) payment of indemnification is not made pursuant to this
Agreement within ten (10) days after receipt by the Company of a written request
therefor, or (v) payment of indemnification is not made within ten (10) days
after a determination has been made that Indemnitee is entitled to
indemnification or such determination is deemed to have been made pursuant to
Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in
an appropriate court of the State of Delaware, or in any other court of
competent jurisdiction, of his entitlement to such indemnification. Indemnitee
shall commence such proceeding seeking an adjudication within 180 days following
the date on which Indemnitee first has the right to commence such proceeding
pursuant to this Section 7(a). The Company shall not oppose Indemnitee's right
to seek any such adjudication.

                      (b) In the event that a determination shall have been made
pursuant to Section 6(b) of this Agreement that Indemnitee is not entitled to
indemnification, any judicial proceeding commenced pursuant to this Section 7
shall be conducted in all respects as a de novo trial, on the merits and
Indemnitee shall not be prejudiced by reason of that adverse determination under
Section 6(b).

                      (c) If a determination shall have been made pursuant to
Section 6(b) of this Agreement that Indemnitee is entitled to indemnification,
the Company shall be bound by such determination in any judicial proceeding
commenced pursuant to this Section 7, absent a prohibition of such
indemnification under applicable law.

                      (d) In the event that Indemnitee, pursuant to this Section
7, seeks a judicial adjudication of his rights under, or to recover damages for
breach of, this Agreement, or to recover under any directors' and officers'
liability insurance policies maintained by the Company the Company shall pay on
his behalf, in advance, any and all expenses (of the types described in the
definition of Expenses in Section 13 of this Agreement) actually and reasonably
incurred by him in such judicial adjudication, regardless of whether Indemnitee
ultimately is determined to be entitled to such indemnification, advancement of
expenses or insurance recovery.

                      (e) The Company shall be precluded from asserting in any
judicial proceeding commenced pursuant to this Section 7 that the procedures and
presumptions of this Agreement are not valid, binding and enforceable and shall
stipulate in any such court that the Company is bound by all the provisions of
this Agreement.






                                       7


               8. Non-Exclusivity; Survival of Rights; Insurance; Subrogation.

                      (a) The rights of indemnification as provided by this
Agreement shall not be deemed exclusive of any other rights to which Indemnitee
may at any time be entitled under applicable law, the certificate of
incorporation of the Company, the Bylaws, any agreement, a vote of stockholders
or a resolution of directors, or otherwise. No amendment, alteration or repeal
of this Agreement or of any provision hereof shall limit or restrict any right
of Indemnitee under this Agreement in respect of any action taken or omitted by
such Indemnitee in his Corporate Status prior to such amendment, alteration or
repeal. To the extent that a change in the Law, whether by statute or judicial
decision, permits greater indemnification than would be afforded currently under
the Bylaws and this Agreement, it is the intent of the parties hereto that
Indemnitee shall enjoy by this Agreement the greater benefits so afforded by
such change. No right or remedy herein conferred is intended to be exclusive of
any other right or remedy, and every other right and remedy shall be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other right or remedy.

                      (b) To the extent that the Company maintains an insurance
policy or policies providing liability insurance for directors, officers,
employees, or agents or fiduciaries of the Company or of any other corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise
which such person serves at the request of the Company, Indemnitee shall be
covered by such policy or policies in accordance with its or their terms to the
maximum extent of the coverage available for any such director, officer,
employee or agent under such policy or policies.

                      (c) In the event of any payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all papers required and take all
action necessary to secure such rights, including execution of such documents as
are necessary to enable the Company to bring suit to enforce such rights.

                      (d) The Company shall not be liable under this Agreement
to make any payment of amounts otherwise indemnifiable hereunder if and to the
extent that Indemnitee has otherwise actually received such payment under any
insurance policy, contract, agreement or otherwise.

               9. Exception to Right of Indemnification. Notwithstanding any
other provision of this Agreement, Indemnitee shall not be entitled to
indemnification under this Agreement with respect to any Proceeding brought by
Indemnitee, or any claim therein, unless (a) the bringing of such Proceeding or
making of such claim shall have been approved by the Board of Directors of the
Company or (b) such Proceeding is being brought by the Indemnitee to assert,
interpret or enforce his rights under this Agreement.

               10. Duration of Agreement. All agreements and obligations of the
Company contained herein shall continue during the period Indemnitee is an
officer or director of the




                                       8


Company (or is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise) and shall continue thereafter so long as Indemnitee
shall be subject to any Proceeding (or any proceeding commenced under Section 7
hereof) by reason of his Corporate Status, whether or not he is acting or
serving in any such capacity at the time any liability or expense is incurred
for which indemnification can be provided under this Agreement. This Agreement
shall be binding upon and inure to the benefit of and be enforceable by the
parties hereto and their respective successors (including any direct or indirect
successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), assigns, spouses,
heirs, executors and personal and legal representatives. This Agreement shall
continue in effect regardless of whether Indemnitee continues to serve as an
officer or director of the Company or any other Enterprise at the Company's
request.

               11. Security. To the extent requested by the Indemnitee and
approved by the Board of Directors of the Company, the Company may at any time
and from time to time provide security to the Indemnitee for the Company's
obligations hereunder through an irrevocable bank line of credit, funded trust
or other collateral. Any such security, once provided to the Indemnitee, may not
be revoked or released without the prior written consent of the Indemnitee.

               12.    Enforcement.

                      (a) The Company expressly confirms and agrees that it has
entered into this Agreement and assumed the obligations imposed on it hereby in
order to induce Indemnitee to serve as an officer or director of the Company,
and the Company acknowledges that Indemnitee is relying upon this Agreement in
serving as an officer or director of the Company.

                      (b) This Agreement constitutes the entire agreement

presently is, nor in the past five years has been, retained to represent: (i)
the Company or Indemnitee in any matter material to either such party (other
than with respect to matters concerning the Indemnitee under this Agreement, or
of other indemnitees under similar indemnification agreements), or (ii) any
other party to the Proceeding giving rise to a claim for indemnification
hereunder. Notwithstanding the foregoing, the term 'Independent Counsel' shall
not include any person who, under the applicable standards of professional
conduct then prevailing, would have a conflict of interest in representing
either the Company or Indemnitee in an action to determine Indemnitee's rights
under this Agreement. The Company agrees to pay the reasonable fees of the
Independent Counsel referred to above and to fully indemnify such counsel
against any and all Expenses, claims, liabilities and damages arising out of or
relating to this Agreement or its engagement pursuant hereto.

                      (f) 'Proceeding' includes any threatened, pending or
completed action, suit, arbitration, alternate dispute resolution mechanism,
investigation, inquiry, administrative hearing or any other actual, threatened
or completed proceeding, whether brought by or in the right of the Company or
otherwise and whether civil, criminal, administrative or investigative, in which
Indemnitee was, is or will be involved as a party or otherwise, by reason of the
fact that Indemnitee is or was a director of the Company, by reason of any
action taken by him or of any inaction on his part while acting as an officer or
director of the Company, or by reason of the fact that he is or was serving at
the request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other Enterprise; in each case
whether or not he is acting or serving in any such capacity at the time any
liability or expense is incurred for which indemnification can be provided under
this Agreement; including one pending on or before the date of this Agreement;
and excluding one initiated by an Indemnitee pursuant to Section 7 of this
Agreement to enforce his rights under this Agreement.

               14. Severability. If any provision or provisions of this
Agreement shall be held by a court of competent jurisdiction to be invalid,
void, illegal or otherwise unenforceable for any reason whatsoever: (a) the
validity, legality and enforceability of the remaining provisions of this
Agreement (including without limitation, each portion of any section of this
Agreement containing any such provision held to be invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall not
in any way be affected or impaired thereby and shall remain enforceable to the
fullest extent permitted by law; and (b) to the fullest extent




                                       10


possible, the provisions of this Agreement (including, without limitation, each
portion of any section of this Agreement containing any such provision held to
be invalid, illegal or unenforceable, that is not itself invalid, illegal or
unenforceable) shall be construed so as to give effect to the intent manifested
thereby.

               15. Modification and Waiver. No supplement, modification,
termination or amendment of this Agreement shall be binding unless executed in
writing by both of the parties hereto. No waiver of any of the provisions of
this Agreement shall be deemed or shall constitute a waiver of any other
provisions hereof (whether or not similar) nor shall such waiver constitute a
continuing waiver.

               16. Notice By Indemnitee. Indemnitee agrees promptly to notify
the Company in writing upon being served with any summons, citation, subpoena,
complaint, indictment, information or other document relating to any Proceeding
or matter which may be subject to indemnification covered hereunder. The failure
to so notify the Company shall not relieve the Company of any obligation which
it may have to the Indemnitee under this Agreement or otherwise unless and only
to the extent that such failure or delay materially prejudices the Company.

               17. Notices. All notices, requests, demands and other
communications hereunder shall be in writing and shall be deemed to have been
duly given if (i) delivered by hand and receipted for by the party to whom said
notice or other communication shall have been directed, or (ii) mailed by
certified or registered mail with postage prepaid, on the third business day
after the date on which it is so mailed:

                      (a) If to Indemnitee, to the address set forth below
Indemnitee signature hereto.

                      (b) If to the Company, to:

or to such other address as may have been furnished to Indemnitee by the Company
or to the Company by Indemnitee, as the case may be.

               18. Identical Counterparts. This Agreement may be executed in one
or more counterparts, each of which shall for all purposes be deemed to be an
original but all of which together shall constitute one and the same Agreement.
Only one such counterpart signed by the party against whom enforceability is
sought needs to be produced to evidence the existence of this Agreement.

               19. Headings. The headings of the paragraphs of this Agreement
are inserted for convenience only and shall not be deemed to constitute part of
this Agreement or to affect the construction thereof.
