Partner, with the power to act in the name, place and stead of the Contributing

connection with or to carry out the transactions contemplated by this Addendum
or the Agreement, and any other documents to be executed in connection with the
Closing as fully as could the Contributing Partner if personally present and
acting.

     The Power of Attorney granted by the Contributing Partner pursuant to this
Section 5 and all authority conferred hereby is granted and conferred subject to
and in consideration of the interests of the Acquiring Partnership and is for
the purpose of completing the transactions contemplated by the Agreement.  The
Power of Attorney granted by this Section 5 and all authority conferred hereby
is coupled with an interest and therefore shall be irrevocable and shall not be
terminated by any act of the Contributing Partner or by operation of law,
whether by the death, disability, incapacity or liquidation of the Grantor or by
the occurrence of any other event or events (including without limitation the
termination of any trust or estate for which the Contributing Partner is acting
as a fiduciary or fiduciaries), and if, after the execution hereof, the
Contributing Partner shall die or become disabled or incapacitated or is
liquidated, or if any other such event or events shall occur before the
completion of the transactions contemplated by the Agreement, the Attorney-in-
Fact shall nevertheless be authorized and directed to complete all such
transactions as if such death, disability, incapacity, liquidation or other
event or events had not occurred and regardless of notice thereof.  The
Contributing Partner acknowledges that the Attorney-in-Fact named in the first
paragraph of this Section 5 have, and any substitute or successor thereof acting
as Attorney-in-Fact may have, an economic interest in the transactions
contemplated by the Agreement.  The Contributing Partner agrees that, at the
request of the Acquiring Partnership, it will promptly execute a separate Power
of Attorney on the same terms set forth in this Section 5, such execution to be
witnessed and notarized if so requested by an Attorney-in-Fact.

     It is understood that the Attorney-in-Fact assumes no responsibility or
liability to any person by virtue of the Power of Attorney granted by the
Contributing Partner hereby.  The Attorney-in-Fact makes no representations with
respect to and shall have no responsibility for the Merger and shall not be
liable for any error of judgment or for any act done or omitted or for any
mistake of fact or law except for his own gross negligence or willful
misconduct.  The Contributing Partner agrees to indemnify the Attorney-in-Fact
for and to hold the Attorney-in-Fact harmless against any loss, claim, damage or
liability incurred on his part arising out of or in connection with it acting as
the Attorney-in-Fact under the Power of Attorney created by the Contributing
Partner hereby, as well as the cost and expense of investigating and defending
against any such loss, claim, damage or liability, except to the extent such
loss, claim, damage or liability is due to the gross negligence or willful
misconduct of the Attorney-in-Fact.  The Contributing Partner agrees that an
Attorney-in-Fact may consult with counsel of his own choice (who may be counsel
for FYA or the Acquiring Partnership) and he shall have full and complete
authorization and protection for any action taken or suffered by him hereunder
in good faith and in accordance with the advice of such counsel.

     The Contributing Partner does hereby ratify and confirm all that the
Attorney-in-Fact shall lawfully do or cause to be done by virtue of the exercise
of the powers granted unto him by such Contributing Partner under this Section
5, and such Contributing Partner authorizes the reliance of third parties on
this Power of Attorney and waives his, her or its rights, if any, as against any
such third party for its reliance hereon.

      ----------------------                                                 
which covers the issuance or resale, as applicable, of any Registrable Shares on

2.   REGISTRATION.
     ------------ 

     (a) Demand Registration. (i) Subject to the conditions set forth in this
         -------------------                                                 
Agreement, after the later to occur of (i) the 30th day following the date on
which the Company becomes eligible to file a Registration Statement on Form S-3
or a similar "short form" registration statement or (ii) the first anniversary
of the date hereof, while Registrable Shares or the Units issued on the Closing
Date are outstanding, any Holder or Holders of at least one-quarter ( 1/4) of
the Units issued on the Closing Date may request, in connection with the
redemption of such Units for Common Stock pursuant to and in accordance with the
Partnership Agreement, that the Company cause to be filed a Registration
Statement providing for the sale by such Holders of all or part of such Holders'
Registrable Shares in the manner specified in such request, including an
underwritten offering in accordance with the terms hereof (each a "Demand
                                                                   ------
Registration"). Within ten (10) days after receipt of a request for a Demand
------------                                                                
Registration, the Company shall promptly give written notice of such proposed
registration to all other Holders. Such Holders shall have the right, by giving
written notice to the Company within fifteen (15) days after such notice
referred to in the preceding sentence has been given by the Company to elect to
have included in the Registration Statement pursuant to a Demand Registration
such of their Registrable Shares as each Holder may request in such notice of
election.  Thereupon, the Company shall use all commercially reasonable efforts
to cause such Registration Statement to be declared effective by the Securities
and Exchange Commission (the "SEC") for all Registrable Shares which the Company
                              ---                                               
has been requested to register no later than ninety (90) days following the
expiration of such fifteen (15) day period.  The Company agrees to use all
commercially reasonable efforts to keep the Registration Statement pursuant to a
Demand Registration continuously effective until the earliest of (a) the date on
which the Holders no longer hold any Registrable Shares registered under such
Registration Statement, (b) the date on which the Registrable Shares are
eligible for sale by the Holders pursuant to Rule 144(k) (or any successor
provision) promulgated under the Securities Act or (c) the date which is six (6)
months from the
<PAGE>
 
effective date of such Registration Statement; provided, however, that such six
(6) month period shall be tolled during the period the Holders' disposition of
Registrable Shares pursuant to a Demand Registration is suspended because of an
event described in Section 3(b).  The Company shall not be obligated under this
Section 2(b): (i) to effect more than one Demand Registration in any twelve-
month period, (ii) to effect more than three Demand Registrations, in the
aggregate, on behalf of the Holders.

     (ii) If the method of disposition specified by the Holder or Holders
requesting a Demand Registration shall be an underwritten public offering, the
Company may designate the managing underwriter of such offering, subject to the
approval of such Holder or Holders which approval shall not be unreasonably
withheld, delayed or conditioned and shall, in connection therewith, (i) enter
into agreements customary in connection therewith (including an underwriting
agreement in customary form) and reasonably acceptable to the Company, (ii)
promptly make available to the Holder or Holders all financial and other records
as shall be reasonably necessary to enable them to exercise their due diligence
responsibilities, (iii) furnish to each Holder and each underwriter, if any, a
signed counterpart, addressed to such Holder or underwriter of (A) an opinion or
opinions of counsel to the Company and (B) a cold comfort letter or letters from
the Company's independent public accountants and (iv) incorporate in a
Prospectus supplement or post effective amendment such information as such
managing underwriter or underwriters requests.  If the managing underwriters
advise the Company in writing that in their opinion the number of Registrable
Shares requested to be included in such offering exceeds the maximum number
which can be included in such offering (1) at a price reasonably related to the
then current market value of the Company's Common Stock or (2) without adversely
affecting the marketability of the offering (the "Maximum Number"), then the
                                                  --------------            
Company will limit the number of Registrable Shares included in such offering to
the Maximum Number, and the Registrable Shares offered shall be selected in the
following order of priority (A) first, the Registrable Shares, if any, to be
offered for the account of the Holders (including the Holder or Holders making
the Demand Registration); provided, however, that such number of Registrable
                          --------  -------                                 
Shares shall be reduced pro-rata on the basis of relative number of any
Registrable Shares requested by each such Holder to be included in such
registration to the extent necessary to reduce the total number of securities of
the Holders offered to the Maximum Amount and (B) second, the securities the
Company proposes to sell pursuant to Section 7.

     (b) Registration Statement Covering Issuance of Common Stock.  In lieu of
         --------------------------------------------------------             
the registration rights set forth in Section 2(a) above, the Company may, in its
sole discretion, prior to the first date upon which the Units held by the
Holders may be redeemed pursuant to the Partnership Agreement (or such other
date as may be required under applicable provisions of the Securities Act) file
a Registration Statement relating to the issuance to Holders of shares of Common
Stock upon the redemption or in exchange for their Units.  Thereupon, the
Company shall use all commercially reasonable efforts to cause such Registration
Statement to be declared effective by the SEC for all shares of Common Stock
covered thereby.  The Company agrees to use all commercially reasonable efforts
to keep such Registration Statement continuously effective until the earlier to
occur of (i) the date which is the 10th anniversary of the date hereof and (ii)
date on which each Holder has redeemed or exchanged all of such Holder's Units
for Common Stock.  In the event that the Company is unable to cause such
Registration Statement to be declared effective by the SEC or is unable to keep
such Registration Statement effective until the earlier of the dates specified
in clause (i) and (ii) in the immediately preceding sentence, then the rights of
each Holder set forth in Sections 2(a) and (b) above shall be restored.

     (c) Notwithstanding any thing to the contrary set forth herein, no Holder
shall have any rights under this Section 2 to request the Company, and the
Company shall have no obligation, to use all commercially reasonable efforts to
cause a Registration Statement to be declared effective by the SEC at any time
after the Common Stock issued to such Holder is (A) sold pursuant to Rule 144
(or any successor provision) under the Securities Act or (B) is eligible for
sale pursuant to Rule 144(K) or any successor provision under the Securities
Act.
<PAGE>
 
     (d) If after a Demand Registration Statement has been declared effective,
the offering of Registrable Shares pursuant to such Demand Registration
Statement is interfered with by any stop order, injunction or other order or
requirement of the SEC or any other governmental agency or court, such Demand
Registration Statement will be deemed not to have become effective during the
period of such interference until the offering of Registrable Shares pursuant to
such Demand Registration Statement may legally resume.

     (e) In the event that the Company shall default in its obligation to file a
Registration Statement within the time period specified in Section 2(a) other
than as a result of any act or omission of a Holder and a Holder shall be
required to undertake any steps to cause the Company to comply with this
Agreement with respect thereto following such default, the Company shall
promptly reimburse such Holder for all reasonable out-of-pocket costs
(including, without limitation, all reasonable attorneys' fees and expenses)
incurred by such Holder in connection with the enforcement of the Company's
obligation to so file (including the reasonable out-of-pocket costs of legal and
other professional advice preparatory to such enforcement).

3.   REGISTRATION PROCEDURE.
     ---------------------- 

     Whenever required under Section 2 to use all commercially reasonable
efforts to effect the registration of any Registrable Shares, the Company shall,
to the extent applicable:

     (a) subject to the last five sentences of Section 3(b), prepare and file
with the SEC a Registration Statement with respect to such Registrable Shares
and use all commercially reasonable efforts to cause such Registration Statement
to become and remain effective for the applicable period as provided in Section
2.

     (b) subject to the last five sentences of this Section 3(b), prepare and
file with the SEC from time to time such amendments and supplements to the
Registration Statement and Prospectus used in connection therewith as may be
necessary to keep the Registration Statement effective and to comply with the
provisions of the Securities Act with respect to the disposition of all the
Registrable Shares throughout the applicable period. Notwithstanding anything to
the contrary contained herein, the Company shall not be required to take any of
the actions described in the previous sentence, in Section 3(a), 3(d) or Section
3(g) to the extent that (i) in the reasonable opinion of the Company (A)
securities laws applicable to such sale would require the Company to disclose
material non-public information ("Non-Public Information") and (B) the
                                  ---------- -----------              
disclosure of such Non-Public Information would materially adversely affect the
Company; (ii) such sale would occur during the measurement period for
determining the amount of Common Stock in connection with the acquisition of a
business or assets by the Company (the "Measurement Period"); or (iii) the
                                        ------------------                
Company is contemplating an underwritten or non-underwritten public offering of
its securities and in the reasonable opinion of the underwriters (or the
Company, in the case of a non-underwritten public offering) such sale would
interfere materially with such public offering by the Company (a "Financing
                                                                  ---------
Period"); and in the event of (i), (ii) or (iii) the Company simultaneously
------                                                                     
delivers written notice to the Holders to the effect that the Holders may not
make offers or sales under the applicable Registration Statement for a period
not to exceed sixty (60) days from the date of such notice; provided, however,
                                                            --------  ------- 
that the Company may only deliver two such notices within any twelve-month
period and shall not deliver such notices consecutively in any twelve-month
period.  In the event the sale by the Holders is suspended because of the
existence of Non-Public Information, the Company will notify the Holders
promptly upon such Non-Public Information being included by the Company in a
filing with the SEC, being otherwise disclosed to the public (other than through
the action of any Holder), or ceasing to be material to the Company, and upon
such notice being given by the Company, the Holders shall again, subject to the
last paragraph of this Section 3, be entitled to sell Registrable Shares as
provided herein.  In the event the sale by the Holders is suspended because it
is proposed to be made during the Measurement Period or the Financing Period, as
applicable, the Company shall specify, in notifying the Holders of the
suspension of the sale, when the Measurement Period or Financing Period, as
applicable, will end, at which time the Holders shall again, subject to the last
paragraph of this Section 3, be
<PAGE>
 
entitled to sell Registrable Shares as provided herein.  If the Measurement
Period or the Financing Period, as applicable, is thereafter changed (but in no
event to a date after the applicable sixty (60) day period), the Company will
promptly notify the Holders of such change and upon the end of the Measurement
Period or Financing Period as so changed, the Holders shall again, subject to
the last paragraph of this Section 3, be entitled to sell Registrable Shares as
provided herein.  If an agreement to which such Measurement Period or Financing
Period, as applicable, relates is terminated prior to the end of the Measurement
Period or Financing Period, as applicable, the suspension period hereunder shall
end immediately and the Company shall promptly notify the Holders of the end of
the suspension period.

     (c) furnish to the Holders such numbers of copies of the Registration
Statement and Prospectus included therein in conformity with the requirements of
the Securities Act and such other documents and information as they may
reasonably request.

     (d) use all commercially reasonable efforts to register or qualify, and
maintain the registration and qualification of, the Registrable Shares covered
by such Registration Statement under such other securities or "blue sky" laws of
such jurisdictions within the United States and its territories as shall be
reasonably appropriate for the distribution of the Registrable Shares covered by
a Registration Statement; provided, however, that the Company shall not be
                          --------  -------                               
required in connection therewith or as a condition thereto to qualify to do
business in or to file a general consent to service of process in any
jurisdiction wherein it would not but for the requirements of this paragraph (d)
be obligated to do so; and provided further, that the Company shall not be
                           -------- -------                               
required to subject itself to taxation in any jurisdiction or to qualify such
Registrable Shares in any jurisdiction in which the securities regulatory
authority requires that any Holder submit any of its Registrable Shares to the
terms, provisions and restrictions of any escrow, lockup or similar agreement(s)
for consent to sell Registrable Shares in such jurisdiction unless such Holder
agrees to do so.

     (e) promptly notify each Holder for whom Registrable Shares are covered by
the applicable Registration Statement, and confirm in writing (i) when the
Registration Statement and any post-effective amendments thereto have become
effective, (ii) when any amendment or supplement to the Prospectus contained in
such Registration Statement has been filed with the SEC, (iii) of the issuance
by the SEC of any stop order suspending the effectiveness of such Registration
Statement or the initiation of any proceedings for that purpose, or the
suspension of any qualification under "blue sky" laws, (iv) at any time when a
Prospectus relating to such Registration Statement is required to be delivered
under the Securities Act, of the happening of an event as a result of which the
Prospectus included 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 light of the circumstances under which they were made.

     (f) use all commercially reasonable efforts to obtain the withdrawal of any
order suspending the effectiveness of a Registration Statement at the earliest
possible moment.

     (g) subject to the last five sentences of Section 3(b), upon the occurrence
of any event contemplated by clause (iv) of Section 3(e), use all commercially
reasonable efforts promptly to prepare and file an amendment or a supplement to
the Prospectus contained in the applicable Registration Statement or any
document incorporated in such Prospectus by reference or prepare, file and
obtain effectiveness of a post-effective amendment to such Registration
Statement, or file any other required document, in any case to the extent
necessary so that, as thereafter delivered to the purchasers of such Registrable
Shares, such Prospectus shall not include an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances under
which they were made.

     (h) otherwise use all commercially reasonable efforts to comply with all
<PAGE>
 
applicable rules and regulations of the SEC.

     (i) use all commercially reasonable efforts to list the Registrable Shares
covered by a Registration Statement with any securities exchange on which the
Common Stock of the Company is then listed.

     (j) If the Company shall hereafter enter into any registration rights or
similar agreement which grants any holder of Common Stock liquidated damages or
similar penalties for failure of the Company to file a registration statement
and/or cause a registration statement to become or remain effective with respect
to such Common Stock, the Holders hereunder shall be entitle to comparable and
proportionate rights and penalties (taking into account the relative number of
shares of Common Stock) with respect to Registrable Shares then outstanding
hereunder.

     In connection with and as a condition to the Company's obligations with
respect to any Registration Statements required to be filed pursuant to Section
2 and this Section 3, each Holder agrees that (i) it will not offer or sell its
Registrable Shares under any Registration Statement until it has received copies
of the Prospectus as then supplemented or amended as contemplated by Section
3(c) and receives notice from the Company that the Registration Statement and
any post-effective amendment thereto have become effective as contemplated in
Section 3(e), (ii) upon receipt of any notice from the Company contemplated by
Section 3(e)(iii), such Holder will forthwith discontinue disposition of the
Registrable Shares pursuant to the applicable Registration Statement until the
Company obtains the withdrawal of any order suspending the effectiveness of such
Registration Statement, (iii) upon receipt of any notice from the Company
contemplated by Section 3(b), such Holder will forthwith discontinue disposition
of the Registrable Shares pursuant to the applicable Registration Statement
until (a) the expiration of the Measurement Period or Financing Period, as
applicable, or the receipt of a notice from the Company that the Non-Public
Information has been included in a filing with the SEC or has otherwise been
disclosed to the public or has ceased to be material to the Company as provided
in Section 3(b) and (b) if applicable, the Holder receives copies of the
supplemented or amended Prospectus contemplated by Section 3(g) and receives
notice that any post-effective amendment has become effective, and (iv) upon
receipt of any notice from the Company contemplated by Section 3(e)(iv) (in
respect of the occurrence of an event contemplated therein), such Holder will
forthwith discontinue disposition of the Registrable Shares pursuant to the
applicable Registration Statement until such Holder receives copies of the
supplemented or amended Prospectus contemplated by Section 3(g) and receives
notice that any post-effective amendment has become effective, and in the case
of clause (iii) and (iv) of this paragraph, if so directed by the Company, such
Holder will deliver to the Company all copies in its possession, other than
permanent file copies then in such Holder's possession, of the Prospectus
covering such Registrable Shares current at the time of receipt of such notice.

4.   EXPENSES.
     -------- 

     The Company shall bear all Registration Expenses incurred in connection
with the registration of the Registrable Shares pursuant to this Agreement,
except that each Holder shall be responsible for any brokerage or underwriting
commissions relating and taxes of any kind (including, without limitation,
stamp, transfer, sales and similar taxes) with respect to the sale, disposition
or transfer of Registrable Shares sold by it and for any legal, accounting and
other expenses incurred by it.

5.   INDEMNIFICATION BY THE COMPANY.
     ------------------------------ 

     (a) The Company agrees to indemnify each of the Holders, their respective

officers, directors, employees, agents, representatives and affiliates, each
other Person who participates as an underwriter in the offer or sale of
Registrable Shares, and each Person, if any, that controls a Holder or any such
underwriter within the meaning of the Securities Act against any and all losses,
claims, damages, actions,
<PAGE>
 
liabilities, costs and expenses (including without limitation reasonable
attorneys' fees, expenses and disbursements documented in writing), joint or
several, to which they may become subject under the Securities Act or otherwise,
insofar as such losses, claims, damages, liabilities, (or actions or proceeding
in respect thereof) costs or expenses arise out of or are based upon any untrue
or alleged untrue statement of material fact contained in any Registration
Statement on the effective date thereof or any Prospectus contained therein, or
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; provided, however,
                                                          --------  ------- 
that the indemnity agreement contained in this Section 5(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Company, provided
                                                                   --------
further that the Company shall not be liable to any Holder, such Holder's
-------                                                                  
directors, officers, employees, agents, representatives and affiliates or
participating or controlling Person in any such case to the extent that any such
loss, claim, damage, liability (or action or proceeding in respect thereof) or
expense arises out of or is based upon (i) an untrue statement or alleged untrue
statement or omission or alleged omission made in such Registration Statement,
any such preliminary prospectus, final prospectus, summary prospectus, amendment
or supplement thereto in reliance upon and in conformity with written
information furnished to the Company for use in connection with the Registration
Statement or the Prospectus contained therein by such Holder, such Holder's
directors, officers, employees, agents, representatives and affiliates or
participating or controlling Person or (ii) such Holder's, such Holder's
directors', officers', employees', agents', representatives' and affiliates' or
participating or controlling Person's failure to send or give a copy of the
final Prospectus furnished to it by the Company at or prior to the time such
action is required by the Securities Act to the Person claiming an untrue
statement or alleged untrue statement or omission or alleged omission if such
statement or omission was corrected in such final prospectus. The obligations of
the Company under this Section 5 shall survive the completion of any offering of
Registrable Shares pursuant to a Registration Statement under this Agreement or
otherwise and shall survive the termination of this Agreement.

     (b) Each Holder requesting or joining in any Registration Statement
severally and not jointly shall indemnify and hold harmless the Company, each of
its directors, officers, employees, agents, representatives and affiliates, each
Person, if any, who controls the Company within the meaning of the Securities
Act, and each agent and any underwriter for the Company (within the meaning of
the Securities Act) against any losses, claims, damages or liabilities, costs
and expenses (including without limitation reasonable attorneys' fees, expenses
and disbursements documented in writing), to which the Company or any such
director, officer, employee, agent, representative, affiliate, controlling
Person, agent or underwriter may become subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) costs, or expenses arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in such Registration Statement or any Prospectus contained therein or
arise out of or are based upon 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, in each case to the extent, but only to the
extent, (i) that such untrue statement or alleged untrue statement or omission
or alleged omission was made in such Registration Statement, preliminary or
final prospectus, summary prospectus or amendments or supplements thereto, in
reliance upon and in conformity with written information furnished by or on
behalf of such Holder for use in connection with such Registration Statement or
the Prospectus contained therein or (ii) such Holder's failure to send or give a
copy of the final prospectus furnished to it by the Company at or prior to the
time such action is required by the Securities Act to the Person claiming an
untrue statement or alleged untrue statement or omission if such statement or
omission was corrected in the final prospectus; provided, however, that the
                                                --------  -------          
indemnity agreement contained in this Section 5(b) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of such Holder.

     (c) Promptly after receipt by an indemnified party under this Section 5 of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against any
<PAGE>
 
indemnifying party under this Section 5, notify the indemnifying party in
writing of the commencement thereof and the indemnifying party shall have the
right to participate in and assume the defense thereof with counsel selected by
the indemnifying party and reasonably satisfactory to the indemnified party;
provided, however, that an indemnified party shall have the right to retain its
--------  -------                                                              
own counsel, with all fees and expenses thereof to be paid by such indemnified
party, and to be apprised of all progress in any proceeding the defense of which
has been assumed by the indemnifying party; and provided further, that in the
                                                -------- -------             
event of a conflict of interest between an indemnifying party and an indemnified
party, an indemnified party shall have the right to retain its own counsel, with
all fees and expenses thereof to be paid by the indemnifying party.  The failure
to notify an indemnifying party promptly of the commencement of any such action,
if and to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 5, but the omission so to notify the indemnifying party will not
relieve it of any liability that it may have to any indemnified party otherwise
than under this Section 5. An indemnifying party shall be entitled to compromise
or settle such action, without the consent of an indemnified party if such
compromise or settlement shall dismiss the action without prejudice and shall
consist solely of monetary payments and such indemnifying party shall make such
payments, or with the consent of an indemnified party in all other cases.  An
indemnified party shall not compromise or settle any action without the consent
of an indemnifying party.

     (d) To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party, in lieu of indemnifying
such indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities in
such proportion as is appropriate to reflect the relative fault of the
indemnifying party and indemnified party in connection with the actions which
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations.  The relative fault of such indemnifying
party and indemnified party shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of material fact or omission or alleged omission to state a material
fact, has been made by, or relates to information supplied by, such indemnifying
party or indemnified party, and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such action.  The amount
paid or payable by a party as a result of the losses, claims, damages or
