     At no time shall the number of shares of Common Stock issued pursuant to or
subject to outstanding Options granted under the Plan exceed [____________]
([_______]) shares of Common Stock; SUBJECT, HOWEVER, to the provisions of
Section 8 of the Plan. For purposes of applying the foregoing limitation, (a) if

been exercised in full, the shares not purchased by the Optionee (or the Holder

issued pursuant to the Plan may be either authorized but unissued shares or
shares held by the Company in its treasury.

5.   ADMINISTRATION

     The Plan shall be administered by the Committee; PROVIDED, HOWEVER, that at
any time and on any one or more occasions the Board may itself exercise any of
the powers and responsibilities assigned the Committee under the Plan and when
so acting shall have the benefit of all of the provisions of the Plan pertaining
to the Committee's exercise of its authorities hereunder. Subject to the
provisions of the Plan, the Committee shall have complete authority, in its
discretion, to make or to select the manner of making all determinations with
respect to each Option to be granted by the Company under the Plan in addition
to any other determination allowed the Committee under the Plan including,
without limitation: (a) the director to receive the Option; (b) the time of
granting an Option; (c) the number of shares subject to an Option; (d) the
exercise price of an Option and the method of payment of such exercise price or
such purchase price; and (e) all other terms and provisions of an Option and the
related Option Agreement. Subject to the provisions of the Plan, the Committee
shall also have complete authority to interpret the Plan, to prescribe, amend
and rescind rules and regulations relating to it, to determine the terms and
provisions of the respective Option Agreements (which need not be identical),
and to make all other determinations necessary or advisable for the
administration of the Plan. The Committee's determinations made in good faith on
matters referred to in this Plan shall be final, binding and conclusive on all
persons having or claiming any interest under the Plan or an Option made
pursuant hereto.

6.   ELIGIBILITY

     Each grant of an Option shall be subject to all applicable terms and
conditions of the Plan (including but not limited to any specific terms and
conditions set forth in the following Section), and such other terms and
conditions, not inconsistent with the terms of the Plan, as the Committee may
prescribe. No prospective holder of an Option shall have any rights with respect
to such Option, unless and until such holder has executed an agreement
evidencing the Option, delivered a fully executed copy thereof to the Company,
and otherwise complied with the applicable terms and conditions of such Option.

7.   SPECIFIC TERMS OF OPTIONS

was not immediately prior to such election or appointment a member of the Board,
shall be granted, on the date of such meeting or other appointment or election,
an Option to purchase [__________] shares of Common Stock (subject to adjustment
as set forth in Section 8). Subject to Section 9, grants of Options under this
Section 7.1 occur automatically without any action being required of the
Optionee, the Committee, the Board, the Company or any other person, entity or
body.]

     7.2. [Annual Grants. Subject to the Plan's effectiveness as set forth in
Section 17, on the anniversary date of each year of service, commencing with the
2007 Annual Meeting of Stockholders of the Company for each Eligible Director
who serves on the Board upon the consummation of the initial public offering,
each Eligible Director who continues to be a director of the Company as of the
close of business of the date of such annual meeting of stockholders or other
anniversary date shall be granted an Option on such business day, to purchase
shares of Common Stock in an amount set by resolution of the Board prior to such
business day, initially to be [________] shares of Common Stock (subject to
adjustment as set forth in Section 8). Subject to Section 9, grants of Options
under this Section 7.2 shall occur automatically without any action being
required of the Optionee, the Committee, the Board, the Company or any other
person, entity or body.]

     7.3. Certain Terms of Option; Exercise Price. Each Option granted to an
Optionee under this Section 7 shall have an exercise price equal to 100% of the
Market Value of the Stock on the applicable Grant Date. No Option granted
pursuant to this Section 7 is intended to qualify as an incentive stock option
within the meaning of Section 422 of the Code. The grants shall be evidenced by
Option Agreements containing provisions that are in all respects consistent with
this Section 7. All of such Option Agreements shall contain identical terms and
conditions, except as otherwise required or permitted by this Section 7.

     7.4. Option Period. The Option period for any Option granted pursuant to
this Section shall be ten (10) years from the date of grant.

     7.5. Exercisability. Each Option granted to an Eligible Director shall be
exercisable as follows: (a) with respect to twenty-five percent (25%) of the
shares of Common Stock underlying such Option, on the date of grant; (b) with
respect to an additional twenty-five percent (25%) of the shares of Common Stock
underlying such Option, on the first anniversary of the date of grant; (c) with
respect to an additional twenty-five percent (25%) of the shares of Common Stock
underlying such Option, on the second anniversary of the date of grant; and (d)
with respect to an additional twenty-five percent (25%) of the shares of Common
Stock underlying such Option, on the third anniversary of the date of grant.
Notwithstanding the foregoing, with respect to any Eligible Director who serves
initially in Class I or Class II immediately after the initial public offering
of the Company's Common Stock, the Committee may determine, prior to the
granting of an Option to such Eligible Director, to grant such Option on such
other vesting terms as the Committee may deem necessary or desirable. In the
case of an Option not otherwise immediately exercisable in full, the Committee
may Accelerate such Option in whole or in part at any time.

     7.6. Effect of Termination of Board Member Relationship. Unless the
Committee shall provide otherwise with respect to any Option, if the Optionee
ceases to be a director of the Company and its Affiliates, any outstanding
Option held by the Optionee or any Holder of such Option shall cease to be
exercisable in any respect not later than ninety (90) days following that

<Page>

                                        6


event and, for the period it remains exercisable following that event, shall be
exercisable only to the extent exercisable at the date of that event.

     7.7. Transferability. Except as otherwise provided in this subsection (f),
Options shall not be transferable, and no Option or interest therein may be
sold, transferred, pledged, assigned, or otherwise alienated or hypothecated,
other than by will or by the laws of descent and distribution. Except as
otherwise provided in this subsection (f), all of a Holder's rights in any
Option may be exercised only during the life of the Holder and only by the
Holder or the Holder's legal representative. However, the Committee may, at or
after the grant of an Option, provide that such Option may be transferred by the
recipient to a family member; PROVIDED, HOWEVER, that any such transfer is
without payment of any consideration whatsoever and that no transfer of an
Option shall be valid unless first approved by the Committee, acting in its sole
discretion. For this purpose, "family member" means any child, stepchild,
grandchild, parent, stepparent, spouse, former spouse, sibling, niece, nephew,
mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or
sister-in-law, including adoptive relationships, any person sharing the initial
grantee's household (other than a tenant or employee), a trust in which the
foregoing persons have more than fifty (50) percent of the beneficial interests,
a foundation in which the foregoing persons (or the initial grantee) control the
management of assets, and any other entity in which these persons (or the
initial grantee) own more than fifty (50) percent of the voting interests. The
Committee may at any time from time to time delegate to one or more officers of
the Company the authority to permit transfers of Options to third parties
pursuant to this Section 7.7, which authorization shall be exercised by such
officer or officers in accordance with guidelines established by the Committee
at any time and from time to time. The restrictions on transferability set forth
in this Section 7.7, shall in no way preclude any Holder from effecting
"cashless" exercises of an Option pursuant to the terms of the Plan.

     7.8. Method of Exercise. An Option may be exercised by the Holder of such
Option by giving written notice, in the manner provided in Section 15,
specifying the number of shares of Common Stock with respect to which the Option
is then being exercised. The notice shall be accompanied by payment in the form
of cash or check payable to the order of the Company in an amount equal to the
exercise price of the shares of Common Stock to be purchased or, subject in each
instance to the Committee's approval, acting in its sole discretion and to such
conditions, if any, as the Committee may deem necessary to avoid adverse
accounting effects to the Company, by delivery to the Company of shares of
Common Stock having a Market Value equal to the exercise price of the shares to
be purchased. No Holder shall be permitted to effect payment of any amount of
the exercise price of the shares of Common Stock to be purchased by executing
and delivering to the Company a promissory note. Receipt by the Company of such
notice and payment in any authorized or combination of authorized means shall
constitute the exercise of the Option. Within thirty (30) days thereafter but
subject to the remaining provisions of the Plan, the Company shall deliver or
cause to be delivered to the Holder or his agent a certificate or certificates
for the number of shares then being purchased. Such shares shall be fully paid
and nonassessable. Notwithstanding any of the foregoing provisions in this
subsection 7.8 to the contrary, (A) no Option shall be considered to have been
exercised unless and until all of the provisions governing such exercise
specified in the Plan and in the relevant Option Agreement shall have been duly
complied with; and (B) the obligation of the Company to issue any shares upon
exercise of an Option is subject to the provisions of Section 9.1 hereof and to
compliance by the Holder with all of the provisions of the Plan and the relevant
Option Agreement.

     7.9. Notification of Disposition. Each person exercising any Incentive
Option granted under the Plan shall be deemed to have covenanted with the
Company to report to the Company

<Page>

                                        7


any disposition of such shares prior to the expiration of the holding periods
specified by Section 422(a)(l) of the Code and, if and to the extent that the
realization of income in such a disposition imposes upon the Company federal,
state, local or other withholding tax requirements, or any such withholding is
required to secure for the Company an otherwise available tax deduction, to
remit to the Company an amount in cash sufficient to satisfy those requirements.

          (j) Rights Pending Exercise. No person holding an Option shall be
deemed for any purpose to be a stockholder of the Company with respect to any of
the shares of Common Stock issuable pursuant to his Option, except to the extent
that the Option shall have been exercised with respect thereto and, in addition,
a certificate shall have been issued therefor and delivered to such holder or
his agent.

8.   ADJUSTMENT PROVISIONS

     8.1. Adjustment for Corporate Actions. All of the share numbers set forth
in the Plan reflect the capital structure of the Company as of _________, 2006.
Subject to the provisions of Section 8.2, if subsequent to such date the
outstanding shares of Common Stock (or any other securities covered by the Plan
by reason of the prior application of this Section) are increased, decreased, or
exchanged for a different number or kind of shares or other securities, or if
additional shares or new or different shares or other securities are distributed
with respect to such shares of Common Stock or other securities, through merger,
consolidation, sale of all or substantially all the property of the Company,
reorganization, recapitalization, reclassification, stock dividend, stock split,
reverse stock split, or other distribution with respect to such shares of Common
Stock, or other securities, an appropriate and proportionate adjustment will be
made in (i) the maximum numbers and kinds of shares provided in Section 4, (ii)
the numbers and kinds of shares or other securities subject to the then
outstanding Options, and (iii) the exercise price for each share or other unit
of any other securities subject to then outstanding Options (without change in
the aggregate purchase price as to which such Options remain exercisable).

     8.2. Change of Control. Subject to the applicable provisions of the Option
Agreement, in the event of a Change of Control, the Committee shall have the
discretion, exercisable in advance of, at the time of, or (except to the extent
otherwise provided below) at any time after, the Change of Control, to provide
for any or all of the following (subject to and upon such terms as the Committee
may deem appropriate): (A) the Acceleration, in whole or in part, of any or all
outstanding Options (including Options that are assumed or replaced pursuant to
clause (C) below) that are not exercisable in full at the time the Change of
Control, such Acceleration to become effective at the time of the Change of
Control, or at such time following the Change of Control that the initial
grantee of the Option ceases to be a director, or at such other time or times as
the Committee shall determine; (B) the assumption of outstanding Options, or the
substitution of outstanding Options with equivalent options, by the acquiring or
succeeding corporation or entity (or an affiliate thereof); or (C) the
termination of all Options (other than Options that are assumed or substituted
pursuant to clause (C) above) that remain outstanding at the time of the
consummation of the Change of Control, PROVIDED THAT, the Committee shall have
made the determination to effect such termination prior to the consummation of
the Change of Control and the Committee shall have given, or caused to be given,
to all Optionees written notice of such potential termination at least five
business days prior to the consummation of the Change of Control, and PROVIDED,
FURTHER, THAT, if the Committee shall have determined in its sole and absolute
discretion that the Corporation make payment or provide consideration to the
holders of such terminated Options on account of such termination, which payment
or consideration shall be on such terms and conditions as the Committee shall
have determined (and which could consist

<Page>

                                        8


of, in the Committee's sole and absolute discretion, payment to the applicable
Optionee or Optionees of an amount of cash equal to the difference between the
Market Value of the shares of Common Stock for which the Option is then
exercisable and the aggregate exercise price for such shares under the Option),
then the Corporation shall be required to make such payment or provide such
consideration in accordance with the terms and conditions so determined by the
Committee; otherwise the Corporation shall not be required to make any payment
or provide any consideration in connection with, or as a result of, the
termination of Options pursuant to the foregoing provisions of this clause (D).
The provisions of this Section 8.2 shall not be construed as to limit or
restrict in any way the Committee's general authority under Sections 7.5 hereof
to Accelerate Options in whole or in part at any time. Each outstanding Option
that is assumed in connection with a Change of Control, or is otherwise to
continue in effect subsequent to a Change of Control, will be appropriately
adjusted, immediately after the Change of Control, as to the number and class of
securities and the price at which it may be exercised in accordance with Section
8.1.

     8.3. Dissolution or Liquidation. Upon dissolution or liquidation of the
Company, each outstanding Option shall terminate, but the Optionee (if at the
time he or she is a board member of the Company or any of its Affiliates) shall
have the right, immediately prior to such dissolution or liquidation, to
exercise the Option to the extent exercisable on the date of such dissolution or
liquidation.

     8.4. Related Matters. Any adjustment in Options made pursuant to this
Section 8 shall be determined and made, if at all, by the Committee and shall
include any correlative modification of terms, including of Option exercise
prices, rates of vesting or exercisability which the Committee may deem
necessary or appropriate so as to ensure that the rights of the Holders in their
respective Options are not substantially diminished nor enlarged as a result of
the adjustment and corporate action other than as expressly contemplated in this
Section 8. No fraction of a share shall be purchasable or deliverable upon
exercise, but in the event any adjustment hereunder of the number of shares
covered by an Option shall cause such number to include a fraction of a share,
such number of shares shall be adjusted to the nearest smaller whole number of
shares. No adjustment of an Option exercise price per share pursuant to this
Section 8 shall result in an exercise price which is less than the par value of
the Common Stock.

9.   SETTLEMENT OF OPTIONS

     9.1. Violation of Law. Notwithstanding any other provision of the Plan or
the relevant Option Agreement, if, at any time, in the reasonable opinion of the
Company, the issuance of shares of Common Stock covered by an Option may
constitute a violation of law, then the Company may delay such issuance and the
delivery of a certificate for such shares until (i) approval shall have been
obtained from such governmental agencies, other than the Securities and Exchange
Commission, as may be required under any applicable law, rule, or regulation and
(ii) in the case where such issuance would constitute a violation of a law
administered by or a regulation of the Securities and Exchange Commission, one
of the following conditions shall have been satisfied:

          (a) the shares are at the time of the issue of such shares effectively
registered under the Securities Act; or

          (b) the Company shall have determined, on such basis as it deems
appropriate (including an opinion of counsel in form and substance satisfactory
to the Company) that the sale,

<Page>

                                        9


transfer, assignment, pledge, encumbrance or other disposition of such shares or
such beneficial interest, as the case may be, does not require registration
under the Securities Act or any applicable state securities laws.

     9.2. Corporate Restrictions on Rights in Stock. Any Common Stock to be
issued pursuant to Options granted under the Plan shall be subject to all
restrictions upon the transfer thereof which may be now or hereafter imposed by
the Certificate of Incorporation and the By-laws of the Company, each as amended
and in effect from time to time. Whenever Common Stock is to be issued pursuant
to an Option, if the Committee so directs at the time of grant (or, if such
Option is an Option, at any time prior to the exercise thereof), the Company
shall be under no obligation, notwithstanding any other provision of the Plan or
the relevant Option Agreement to the contrary, to issue such shares until such
time, if ever, as the recipient of the Option (and any person who exercises any
Option, in whole or in part), shall have become a party to and bound by any
agreement that the Committee shall require in its sole discretion. In addition,
any Common Stock to be issued pursuant to Options granted under the Plan shall
be subject to all stop-transfer orders and other restrictions as the Committee
may deem advisable under the rules, regulations and other requirements of any
stock exchange upon which the Common Stock is then listed, and any applicable
federal or state securities laws, and the Committee may cause a legend or
legends to be put on any such certificates to make appropriate reference to such
restrictions.

     9.3. Investment Representations. The Company shall be under no obligation
to issue any shares covered by an Option unless the shares to be issued pursuant
to Options granted under the Plan have been effectively registered under the
Securities Act or the Holder shall have made such written representations to the
Company (upon which the Company believes it may reasonably rely) as the Company
may deem necessary or appropriate for purposes of confirming that the issuance
of such shares will be exempt from the registration requirements of that Act and
any applicable state securities laws and otherwise in compliance with all
applicable laws, rules and regulations, including but not limited to that the
Holder is acquiring shares for his or her own account for the purpose of
investment and not with a view to, or for sale in connection with, the
distribution of any such shares.

     9.4. Registration. If the Company shall deem it necessary or desirable to
register under the Securities Act or other applicable statutes any shares of
Common Stock issued or to be issued pursuant to Options granted under the Plan,
or to qualify any such shares of Common Stock for exemption from the Securities
Act or other applicable statutes, then the Company shall take such action at its
own expense. The Company may require from each recipient of an Option, or each
holder of shares of Common Stock acquired pursuant to the Plan, such information
in writing for use in any registration statement, prospectus, preliminary
prospectus or offering circular as is reasonably necessary for such purpose and
may require reasonable indemnity to the Company and its officers and directors
from such holder against all losses, claims, damage and liabilities arising from
such use of the information so furnished and caused by any untrue statement of
any material fact therein or caused by the omission to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances under which they were made.

     9.5. Look-Up. Without the prior written consent of the Company or the
managing underwriter in any public offering of shares of Common Stock, no Holder
shall sell, make any short sale of, loan, grant any option for the purchase of,
pledge or otherwise encumber, or otherwise dispose of, any shares of Common
Stock during the one hundred-eighty (180) day period commencing on the effective
date of the registration statement relating to any underwritten

                                       10


public offering of securities of the Company. The foregoing restrictions are
intended and shall be construed so as to preclude any Holder from engaging in
any hedging or other transaction that is designed to or reasonably could be
expected to lead to or result in, a sale or disposition of any shares of Common
Stock during such period even if such shares of Common Stock are or would be
disposed of by someone other than such Holder. Such prohibited hedging or other
transactions would include, without limitation, any short sale (whether or not
against the box) or any purchase, sale or grant of any right (including without
limitation any put or call option) with respect to any shares of Common Stock or
with respect to any security that includes, relates to, or derives any
significant part of its value from any shares of Common Stock. Without limiting
the generality of the foregoing provisions of this Section 9.5, if, in
connection with any underwritten public offering of securities of the Company,
the managing underwriter of such offering requires that the Company's directors
and officers enter into a lock-up agreement containing provisions that are more
restrictive than the provisions set forth in the preceding sentence, then (a)
each Holder (regardless of whether or not such Holder has complied or complies
with the provisions of clause (b) below) shall be bound by, and shall be deemed
to have agreed to, the same lock-up terms as those to which the Company's
directors and officers are required to adhere; and (b) at the request of the
Company or such managing underwriter, each Holders shall execute and deliver a
lock-up agreement in form and substance equivalent to that which is required to
be executed by the Company's directors and officers.

     9.6. Placement of Legends; Stop Orders; Etc. Each share of Common Stock to
be issued pursuant to Options granted under the Plan may bear a reference to the
investment representations made in accordance with Section 9.3 in addition to
any other applicable restrictions under the Plan, the terms of the Option and,
if applicable, under any agreement between the Company and the Optionee and/or
Holder, and to the fact that no registration statement has been filed with the
Securities and Exchange Commission in respect to such shares of Common Stock.
All certificates for shares of Common Stock or other securities delivered under
the Plan shall be subject to such stock transfer orders and other restrictions
as the Committee may deem advisable under the rules, regulations, and other
requirements of any stock exchange upon which the Common Stock is then listed,
and any applicable federal or state securities law, and the Committee may cause
a legend or legends to be placed on any such certificates to make appropriate
reference to such restrictions.

     9.7. Tax Withholding. Whenever shares of Common Stock are issued or to be
issued pursuant to Options granted under the Plan, the Company shall have the
right to require the recipient to remit to the Company an amount sufficient to
satisfy federal, state, local or other withholding tax requirements if, when,
and to the extent required by law (whether so required to secure for the Company
an otherwise available tax deduction or otherwise) prior to the delivery of any
certificate or certificates for such shares. The obligations of the Company
under the Plan shall be conditional on satisfaction of all such withholding
obligations and the Company shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
recipient of an Option. However, in such cases Holders may elect, subject to the
approval of the Committee, acting in its sole discretion, to satisfy an
applicable withholding requirement, in whole or in part, by having the Company
withhold shares to satisfy their tax obligations. Holders may only elect to have
shares of Common Stock withheld having a Market Value on the date the tax is to
be determined equal to the minimum statutory total tax which could be imposed on
the transaction. All elections shall be irrevocable, made in writing, signed by
the Holder, and shall be subject to any restrictions or limitations that the
Committee deems appropriate.

10.  RESERVATION OF STOCK

     The Company shall at all times during the term of the Plan and any
outstanding Options granted hereunder reserve or otherwise keep available such
number of shares of Common Stock as will be sufficient to satisfy the
requirements of the Plan (if then in effect) and such Options and shall pay all
fees and expenses necessarily incurred by the Company in connection therewith.

11.  NO SPECIAL SERVICE RIGHTS

     Nothing contained in the Plan or in any Option Agreement shall confer upon
any recipient of an Option any right with respect to any employment, consulting
or Board member relationship with the Company (or any Affiliate), or interfere
in any way with the right of the Company (or any Affiliate), subject to the
terms of any separate agreement or provision of law or corporate articles or
by-laws to the contrary, at any time to terminate Board member or to increase or
decrease, or otherwise adjust, the other terms and conditions of the recipient
Board member relationship with the Company and its Affiliates.

12.  NONEXCLUSIVITY OF THE PLAN

     Neither the adoption of the Plan by the Board nor the submission of the
Plan to the stockholders of the Company shall be construed as creating any
limitations on the power of the Board to adopt such other incentive arrangements
as it may deem desirable, including without limitation, the granting of stock
options and restricted stock other than under the Plan, and such arrangements
may be either applicable generally or only in specific cases.

13.  TERMINATION AND AMENDMENT OF THE PLAN

     The Board may at any time terminate the Plan or make such amendments or
modifications of the Plan as it shall deem advisable. In the event of the
termination of the Plan, the terms of the Plan shall survive any such
termination with respect to any Option that is outstanding on the date of such
termination, unless the holder of such Option agrees in writing to terminate
such Option or to terminate all or any of the provisions of the Plan that apply
to such Option. Unless the Board otherwise expressly provides, any amendment or
modification of the Plan shall affect the terms of any Option outstanding on the
date of such amendment or modification as well as the terms of any Option made
prior to, or from and after, the date of such amendment or modification;
PROVIDED, HOWEVER, that, except to the extent otherwise provided in the last
sentence of this paragraph, (i) no amendment or modification of the Plan shall
apply to any Option that is outstanding on the date of such amendment or
modification if such amendment or modification would reduce the number of shares
subject to such Option, increase the purchase price applicable to shares subject
to such Option or materially adversely affect the provisions applicable to such
Option that relate to the vesting or exercisability of such Option or of the
shares subject to such Option, and (iii) no amendment or modification of the
Plan shall apply to any Option that is outstanding on the date of such amendment
or modification unless such amendment or modification of the Plan shall also
apply to all other Options outstanding on the date of such amendment or
modification. In the event of any amendment or modification of the Plan that is
described in clause (i) or (ii) of the foregoing proviso, such amendment or
modification of the Plan shall apply to any Option outstanding on the date of
such amendment or modification only if the recipient of such Option consents in
writing thereto.

<Page>

                                       12


     The Committee may amend or modify, prospectively or retroactively, the
terms of any outstanding Option without amending or modifying the terms of the
Plan itself, PROVIDED THAT as amended or modified such Option is consistent with
the terms of the Plan as in effect at the time of the amendment or modification
of such Option, but no such amendment or modification of such Option shall,
without the written consent of the recipient of such Option, reduce the number
of shares subject to such Option, increase the purchase price applicable to
shares subject to such Option, adversely affect the provisions applicable to
such Option that relate to the vesting or exercisability of such Option or of
the shares subject to such Option, or otherwise materially adversely affect the
terms of such Option (except for amendments or modifications to the terms of
such Option or of the stock subject to such Option that are expressly permitted
by the terms of the Plan or that result from any amendment or modification of
the Plan in accordance with the provisions of the first paragraph of this
Section 13).

     In addition, notwithstanding anything express or implied in any of the
foregoing provisions of this Section 13 to the contrary, the Committee may amend
or modify, prospectively or retroactively, the terms of any outstanding Option
to the extent the Committee reasonably determines necessary or appropriate to
conform such Option to the requirements of Section 409A of the Code (concerning
non-qualified deferred compensation), if applicable.

14.  INTERPRETATION OF THE PLAN

     In the event of any conflict between the provisions of this Plan and the
provisions of any applicable Option Agreement, the provisions of this Plan shall
control, except if and to the extent that the conflicting provision in such
Option Agreement was authorized and approved by the Committee at the time of the
grant of the Option evidenced by such Option Agreement or is ratified by the
Committee at any time subsequent to the grant of such Option, in which case the
conflicting provision in such Option Agreement shall control. Without limiting
the generality of the foregoing provisions of this Section 14, insofar as
possible the provisions of the Plan and such Option Agreement shall be construed
so as to give full force and effect to all such provisions. In the event of any
conflict between the provisions of this Plan and the provisions of any other
agreement between the Company and the Holder, the provisions of such agreement
shall control, but insofar as possible the provisions of the Plan and any such
agreement shall be construed so as to give full force and effect to all such
provisions.

15.  NOTICES AND OTHER COMMUNICATIONS

     Any notice, demand, request or other communication hereunder to any party
shall be deemed to be sufficient if contained in a written instrument delivered
in person or duly sent by first class registered, certified or overnight mail,
postage prepaid, or telecopied with a confirmation copy by regular, certified or
overnight mail, addressed or telecopied, as the case may be, (i) if to the
recipient of an Option, at his or her residence address last filed with the
Company and (ii) if to the Company, at its principal place of business,
addressed to the attention of its Chief Executive Officer, or to such other
address or telecopier number, as the case may be, as the addressee may have
designated by notice to the addressor. All such notices, requests, demands and
other communications shall be deemed to have been received: (i) in the case of
