limited liability company (the "Company"), has been deemed advisable and has
been adopted pursuant to the terms of Section 6.7 of the Plan by the Company's
Board of Directors and is effective on December 19, 2000. Terms used herein but
not otherwise defined shall have the meanings given to such terms in the Plan.

         1.       AMENDMENT TO THE PLAN.

                  law and approved by the Board, by delivery of Common Units,
                  previously acquired and currently owned by the Participant (or
                  by the Participant and his or her spouse jointly) and
                  purchased or held for the requisite period of time as
                  necessary to avoid a charge to the Company's earnings for
                  financial reporting purposes, having an aggregate Fair Market
                  Value on the date of exercise of the Option equal to such

                  Association of Securities Dealers, and, in any case, if
                  permitted by applicable law, through a "cashless exercise"
                  procedure approved by the Board whereby the Participant may
                  deliver irrevocable instructions to a broker to deliver
                  promptly to the Company cash in an amount equal to such
                  exercise price and any taxes required as a result of such
                  exercise; or (iv) by a combination of the consideration
                  provided for in the foregoing clauses (i) through (iii)."

2.       Section 5.9 of the Option Plan is amended by adding a new sentence at
the end of such section to read as follows:

changed by this Second Amendment, continue in full force and effect.<PAGE>   1

                  (b) prepare and file with the Commission such amendments and

                                       2
<PAGE>   3
                  (c) furnish to each seller of Registerable Stock such number
         of copies of the registration statement and the prospectus included
         therein and any amendment or supplement thereto as such person may
         reasonably request in order to facilitate the public sale of the
         Registerable Stock covered by such registration statement;

                  (d) use its best efforts to register or qualify the
         Registerable Stock covered by such registration statement under the
         securities or blue sky laws of a reasonable number of jurisdictions
         (provided that the Company will not be required to (i) qualify
         generally to do business in any jurisdiction where it would not
         otherwise be required to qualify but for this paragraph (d), (ii)
         subject itself to taxation in any such jurisdiction or (iii) consent to
         general service of process in any jurisdiction);

                  (e) promptly notify each seller of Registerable Stock (i) when
         such registration statement or any amendment or supplement thereto or
         to the prospectus contained therein has been filed, (ii) of any request
         by the Commission for amendments or supplements to such registration
         statement or prospectus or for additional information from such seller,
         (iii) of the issuance by the Commission of any stop order suspending
         the effectiveness of such registration statement or the initiation of
         proceedings for that purpose, or (iv) of the receipt by the Company of
         any notification with respect to the suspension of the qualification of
         the Registerable Stock for sale in any jurisdiction or the initiation
         or threatening of any proceeding for that purpose;

                  (f) promptly notify each seller of Registerable Stock at any
         time when a prospectus relating thereto is required to be delivered
         under the Securities Act, of the happening of any event of which the
         Company is aware as a result of which the prospectus contained in such
         registration statement, as then in effect, includes an untrue statement
         of a material fact or omits to state any material fact required to be
         stated therein or necessary to make the statements therein not
         misleading in the light of the circumstances then existing, and as
         promptly as practicable thereafter prepare and file with the Commission
         a supplement or amendment to such prospectus, such registration
         statement or any document incorporated therein by

                                       3
<PAGE>   4
         reference, or make such other filing, such that as thereafter delivered
         to the purchasers of Registerable Stock the prospectus will not contain
         an untrue statement of material fact or omit to state any material fact
         necessary to make the statements therein not misleading provided,
         however, in no event shall the registration statement be unavailable
         (i) for any continuous period in excess of sixty (60) days or (ii) for
         an aggregate of ninety (90) days or more, during the Distribution
         Period.

                  (g) use its reasonable best efforts to obtain the withdrawal
         of any order suspending the effectiveness of such registration
         statement.

         In connection with each registration hereunder, each seller of
Registerable Stock shall furnish to the Company in writing such information with
respect to himself and the proposed distribution by him as shall be reasonably
necessary in order to assure compliance with federal and applicable state
securities laws, including, without limitation, such information as shall enable
the Company to prepare prospectus supplements as and when required to enable
pledgees or donees of such seller to sell shares of Registerable Stock under the
registration statement filed pursuant to Section 2 hereof.

         4. Expenses. All expenses incurred by the Company in complying with
Sections 2 and 3 hereof, including, without limitation, all registration and
filing fees, printing expenses, fees and disbursements of counsel and
independent public accountants for the Company, fees of the National Association
of Securities Dealers, Inc., transfer taxes, fees of transfer agents and
registrars, and the reasonable fees and disbursements of one counsel for the
holders of Registerable Stock will be paid by the Company in connection with the
registration statement filed pursuant to Sections 2 and 3 hereof.

         5. Indemnification. The Company will indemnify and hold harmless each
seller of Registerable Stock under the registration statement filed pursuant to
Sections 2 and 3 and each other person, if any, who controls such seller within
the meaning of the Securities Act, and each partner, director or officer of such
persons, against any losses, claims, damages or liabilities, joint or several,
to which such seller, partner, officer, director or controlling person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon (i) any untrue statement or alleged untrue statement of any
material fact contained or incorporated by reference in the registration
statement filed pursuant to Sections 2 and 3 hereof,

                                       4
<PAGE>   5
any prospectus contained therein, or any amendment or supplement thereof, (ii)
the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
(iii) any violation or alleged violation by the Company of the Securities Act,
the Exchange Act, any state securities law or any rule or regulation promulgated
under any of the same in connection with the offering covered by such
registration statement, and the Company will reimburse each such seller,
partner, officer, director and each such controlling person for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Company will not be liable in any such case if and to the extent that
any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission so
made in reliance upon and in conformity with information furnished by such
seller or any of its partners, officers, directors or such controlling person in
writing specifically for use in such registration statement or prospectus.

                     Each seller of such Registerable Stock under the
registration statement filed pursuant to Sections 2 and 3 hereof, severally and
not jointly, will indemnify and hold harmless the Company and each person, if
any, who controls the Company within the meaning of the Securities Act, each
officer of the Company who signs the registration statement, each director of
the Company, and each person who controls any of the foregoing within the
meaning of the Securities Act, against all losses, claims, damages or
liabilities, joint or several, to which the Company or such officer or director
or controlling person may become subject under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon (i) any untrue statement or alleged
untrue statement of any material fact contained in the registration statement
filed pursuant to Sections 2 and 3 hereof, any prospectus contained therein, or
any amendment or supplement thereof, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under any of the same in
connection with the offering covered by such registration statement, and each
such seller will reimburse the Company and each such officer, director and
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that such seller will be liable
hereunder in any such case if and only to the extent that any such loss, claim,
damage or liability

                                       5
<PAGE>   6
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in reliance upon and in conformity with
information furnished in writing to the Company by such seller specifically for
use in such registration statement or prospectus. Notwithstanding the foregoing,
(i) no seller shall be liable for payments of amounts paid in settlement of any
loss, claim, damage, liability or action if such settlement is effected without
the consent of such seller (which consent shall not be unreasonably withheld),
and (ii) in no event shall the liability of any seller of Registerable Stock
under this Section 5 in connection with any registration exceed the proceeds
received by such seller from the sale of shares of Registerable Stock in such
registration.

         Promptly after receipt by an indemnified party hereunder of notice of
the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof; provided, however, that the failure
of any indemnified party to give notice to such indemnifying party as provided
herein shall not relieve such indemnifying party of its obligations under the
foregoing provisions of this Section 5, except and solely to the extent that
such indemnifying party is actually prejudiced by such failure to give notice.
In case any such action shall be brought against any indemnified party and it
shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party, if it shall actually undertake the
defense thereof, shall not be liable to such indemnified party under this
Section 5 for any legal expenses subsequently incurred by such indemnified party
in connection with the defense thereof other than reasonable costs of
investigation and of liaison with counsel so selected; provided, however, that,
if the defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be reasonable defenses available to it which are different from
or additional to those available to the indemnifying party, or if the interests
of the indemnified party reasonably may be deemed to conflict with the interests
of the indemnifying party, the indemnified party shall have the right to select
a separate counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the expenses and fees of such
separate counsel and other expenses related to such participation to be
reimbursed by the indemnifying party as incurred.

                                       6
<PAGE>   7
         Any indemnified party shall have the right to retain its own counsel in
any such action, but the fees and disbursements of such counsel shall be at the
expense of such indemnified party unless (i) the indemnifying party shall have
failed to retain counsel for the indemnified person as aforesaid or shall have
failed to defend such action in accordance with the preceding paragraph or (ii)
the indemnifying party and such indemnified party shall have mutually agreed to
the retention of such counsel. It is understood that the indemnifying party
shall not, in connection with any action or related actions in the same
jurisdiction, be liable for the fees and disbursements of more than one separate
firm qualified in such jurisdiction to act as counsel for the indemnified party.
The indemnifying Party shall not, without the consent of the indemnified Party,
which consent shall not be unreasonably withheld or delayed, consent to the
entry of any judgment or enter into any settlement with respect to such action;
provided, that, unless agreed to by the indemnified party, such judgment or
settlement must include an unconditional release of the indemnified party from
all liability in respect of such action. The indemnifying party shall not be
liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party
from and against any loss or liability by reason of such settlement or judgment.

         If the indemnification provided for in the first two paragraphs of this
Section 5 is unavailable or insufficient to hold harmless an indemnified party
under such paragraphs in respect of any losses, claims, damages or liabilities
or actions in respect thereof referred to therein, then each indemnifying party
shall in lieu of indemnifying such indemnified party contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims,
damages, liabilities or actions in such proportion as appropriate to reflect the
relative fault of the Company, on the one hand, and the sellers of such
Registerable Stock, on the other, in connection with the statements or omissions
which resulted in such losses, claims, damages, liabilities or actions as well
as any other relevant equitable considerations. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact relates to information supplied by the
Company, on the one hand, or the sellers of such Registerable Stock, on the
other, and to the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
each of you agree that it would not be just and equitable if contributions
pursuant to this paragraph were determined by pro rata allocation (even if all
of the sellers of such Registerable Stock were treated as one entity for such
purpose) or by any other

                                       7

indemnified party as a result of the losses, claims, damages, liabilities or
action in respect thereof, referred to above in this paragraph, shall be deemed

party in connection with investigating or defending any such action or claim.

they would have otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission. No person guilty of fraudulent
misrepresentations (within the meaning of Section 11(f) of the Securities Act),
shall be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation.

                  (b) The Company shall use its reasonable best efforts to file

         Exchange Act.

                  (c) The Company shall furnish to each seller of Registerable

         of the most recent annual or quarterly report of the Company, and (iii)
         such other reports and documents so filed as a holder may reasonably
         request to avail itself of any rule or regulation of the Commission
         allowing a holder of Registerable Stock to sell any such securities
         without registration.
