       6. Options. The Committee may grant Options in accordance with the Plan,

Option and Agreement shall be subject to the following conditions:

              (a) Purchase Price. The purchase price for Shares under each
Option shall be set forth in the applicable Agreement.

              (b) Duration. Options granted hereunder shall be for such term as

              (d) Vesting. Each Option shall become exercisable as determined by
the Board or Committee as set forth in the Agreement. The Committee may
accelerate the exercisability of any Option or portion thereof at any time.

              (e) Termination of Employment or Service. Unless otherwise set
forth in an Agreement, if Optionee's employment or service with the Company or a
Subsidiary is terminated for any reason, all Options that are not exercisable as
of the date of such termination shall terminate as of the date of termination
and all exercisable Options shall (unless earlier terminated in accordance with
their terms) remain exercisable for a period of 60 days immediately following
the date of termination and shall terminate thereafter.

              (f) Method of Exercise. The exercise of an Option shall be made
only by a written notice delivered to the Secretary of the Company at the
Company's principal executive office, specifying the number of Shares to be
purchased and accompanied by payment therefor and otherwise in accordance with
the Agreement pursuant to which the Option was granted. The purchase price for
any Shares purchased pursuant to the exercise of an Option shall be paid in full
upon such exercise in cash, by check, or, at the discretion of the Committee and
upon such terms and conditions as the Committee shall approve, by transferring
Shares to the Company or by a cashless exercise procedure. Any Shares
transferred to the Company as payment of the purchase price under an Option
shall be valued at their Fair Market Value on the day preceding the date of
exercise of such Option. If requested by the Committee, the Optionee shall
deliver the Agreement evidencing the Option to the Secretary of the Company who
shall endorse thereon a notation of such exercise and return such Agreement to
the Optionee.

              (g) LLC Agreement. All Options granted pursuant to the Plan and
all Shares acquired under the Plan shall be subject to and governed by certain
sections of the LLC Agreement, as described below. For the purposes of the
applicable sections of the LLC Agreement enumerated below, an Option granted
hereunder shall be treated as if it were granted to a Management Member and a
Share acquired under the Plan shall be treated as a Unit held by a Management
Member.

              (i) Options shall be governed by and subject to the provisions of
Article XI of the LLC Agreement.

              (ii) Shares shall be governed by and subject to the following
provisions of the LLC Agreement:

                     (A) sections 8.1 and 8.2;

                     (B) prior to an IPO Event, all of the sections of Article
                     IX;

                     (C) all of the sections of Article X except for section
                     10.6;

                     (D) all of the sections of Article XI;

                     (E) all of the sections of Article 12 except for section
                     12.1; and

                     (F) all of the sections of Article XIII.

Notwithstanding clauses (i) and (ii) above, the rights and obligations hereunder
shall terminate in accordance with Article XVI of the LLC Agreement.

                7. Adjustments.

            (a) Adjustment for Change in Capitalization. In the event that the
Committee shall determine that any dividend or other distribution (whether in
the form of cash, stock of the Corporation, or other property),
re-capitalization, stock split, reverse stock split, reorganization, merger,
consolidation, spin-off, combination, repurchase, or share exchange, or other
similar corporate transaction or event, makes an adjustment appropriate in order
to prevent dilution or enlargement of the rights of Optionees under the Plan,
then the Committee shall make such equitable changes or adjustments as it deems
necessary or appropriate to (1) the number and kind of shares of stock of the
Corporation issuable in respect of outstanding Options and/or (2) the exercise
price of the Options.

            (b) Adjustment for Change or Exchange of Shares for Other
Consideration. In the event the outstanding Shares shall be changed into or
exchanged for any other class or series of capital stock or cash, securities or
other


                                      7
<PAGE>   8
property pursuant to a re-capitalization, reclassification, merger,
consolidation, combination or similar transaction ("Transaction"), then, unless
otherwise determined by the Committee, (1) each Option shall thereafter become
exercisable for the number and/or kind of capital stock, and/or the amount of
cash, securities or other property so distributed, into which the Shares
subject to the Option would have been changed or exchanged had the Option been
exercised in full prior to such transaction, provided that, if the kind or
amount of capital stock or cash, securities or other property received in such
transaction is not the same for each outstanding Share, then the kind or amount
of capital stock or cash, securities or other property for which the Option
shall thereafter become exercisable shall be the kind and amount so receivable
per share by a plurality of the Shares, and provided further that, if
necessary, the provisions of the Option shall be appropriately adjusted so as
to be applicable, as nearly as may reasonably be, to any shares of capital
stock, cash, securities or other property thereafter issuable or deliverable
upon exercise of the Option.

       8. Termination and Amendment of the Plan. The Plan shall terminate on the
day preceding the tenth anniversary of its effective date, except with respect
to Options outstanding on such date, and no Options may be granted thereafter.
The Board may sooner terminate or amend the Plan at any time, and from time to
time.

       Except as provided in Section 6(i) and 7 hereof, rights and obligations
under any Option granted before any amendment of the Plan shall not be adversely
altered or impaired by such amendment, if such alteration or impairment would be
material, except with the consent of the Optionee.

       (9) Nonexclusivity of the Plan. The adoption of the Plan by the Board
shall not be construed as creating any limitations on the power of the Board to
adopt other incentive arrangements as it may deem desirable, including, without
limitation, the granting of stock options otherwise than under the Plan, and
such arrangements may be either applicable generally or only in specific cases.

                                       8

at the sole discretion of the Board or the Committee;

agencies as may be deemed necessary or appropriate by the Committee.

              (c) Except as otherwise provided in Section 8, the Board may make
such changes as may be necessary or appropriate to comply with the rules and

the Committee determines,

<PAGE>   10

in its absolute discretion, that the listing, registration or qualification of
Shares issuable pursuant to the Plan is required by any securities exchange or
under any state or federal law, or the consent or approval of any governmental
regulatory body is necessary or desirable as a condition of, or in connection
with, the grant of an Option, or the issuance of Shares, no Options, shall be
granted or payment made or Shares issued, in whole or in part, unless listing,
registration, qualification, consent or approval has been effected or obtained
free of any conditions as acceptable to the Committee.

              (e) In the event that the disposition of Shares acquired pursuant
to the Plan is not covered by a then current registration statement under the
Securities Act and is not otherwise exempt from such registration, such Shares
shall be restricted against transfer to the extent required by the Securities
Act or regulations thereunder, and the Committee may require an Optionee
receiving Shares pursuant to the Plan, as a condition precedent to receipt of
such Shares, to make such representations as the Committee deems appropriate,
including, but not limited to a representation to the Company in writing that
the Shares acquired by such Optionee are acquired for investment only and not
with a view to distribution.

Options previously granted to that Optionee. The grant of multiple Options may

Committee.

federal, state or local income taxes and other amounts which the Company is
required by law to withhold. Notwithstanding anything in the Plan to the
contrary, the Committee, in its discretion, may permit an Optionee (or
beneficiary or other person entitled to act on behalf of an Optionee) to elect
to pay a portion or all of the amount requested by the Company for such taxes,
at such time and in such manner as the Committee shall deem appropriate,
including, but not limited to, authorizing the Company to withhold, or agreeing
to surrender to the Company, Shares or other Company securities or property, or
