effectiveness of such Registration Statement and cannot last more than 180 days

offering, the Company shall not, without the prior written consent of Investor,
effect any public sale or distribution of securities similar to those being
registered, or any securities convertible into or exercisable or exchangeable
for such securities, for such period as shall be determined by the managing
underwriters, which period shall not begin more than 10 days prior to the
effectiveness of the Registration Statement pursuant to which such Public
Offering shall be made and shall not last more than 90 days after the closing of
sale of securities pursuant to such Registration Statement (except as part of
such underwritten registration or pursuant to registrations on Forms S-4 or S-8

registration of any Registrable Units, the Company shall, as expeditiously as
practicable:

                   (i)   use its best efforts to cause a Registration Statement

               Registrable Units have been disposed of (if earlier);

                   (ii)  furnish, at least five business days before filing a

               counsel selected by Investor (the "Investor's Counsel") copies of

               such five-business-day period need not apply to successive drafts
               of the same document proposed to be filed so long as such
               successive drafts are supplied to such counsel in advance of the
               proposed filing by a period of time that is customary and
               reasonable under the circumstances);

                   (iii) prepare and file with the Commission such amendments
               and supplements to such Registration Statement and the Prospectus
               used in connection therewith as may be necessary to keep such

               the lesser of a period of 90 days or until all of such
               Registrable Units have been disposed of (if earlier) and to
               comply with the provisions of the Securities Act with respect to
               the sale or other disposition of such Registrable Units;

                   (iv)   notify the Investor's Counsel promptly in writing (A)

               additional information with respect thereto, (B) of the issuance
               by the Commission of any stop order suspending the effectiveness
               of such Registration Statement or Prospectus or any amendment or
               supplement thereto or the initiation of any proceedings for that
               purpose and (C) of the receipt by the Company of any notification
               with respect to the suspension of the qualification of such
               Registrable Units for sale in any jurisdiction or the initiation
               or threatening of any proceeding for such purposes;

                   (v)    use its best efforts to register or qualify such
               Registrable Units under such other securities or blue sky laws of
               such jurisdictions as Investor reasonably requests and do any and
               all other acts and things which may be reasonably necessary or
               advisable to enable Investor to consummate the disposition in
               such jurisdictions of such Registrable Units; provided, however,
                                                             -----------------
               that the Company will not be required to qualify generally to do
               business, subject itself to general taxation or consent to

               otherwise be required so to do but for this clause (v);

                   (vi)   furnish to Investor such number of copies of a summary

               Authorities as may be necessary by virtue of the business and
               operations of the Company to enable Investor to consummate the
               disposition of such Registrable Units;

                   (viii) notify Investor on a timely basis at any time when a
               Prospectus relating to such Registrable Units is required to be
               delivered under the Securities Act within the appropriate period
               mentioned in clause (i) of this Section if the Company becomes
               aware of the happening of any 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 a material fact required to be stated therein or
               necessary to make the statements therein not misleading in light
               of the circumstances then existing and, at the request of
               Investor, prepare and furnish to Investor a reasonable number of
               copies of a supplement to or an amendment of such Prospectus as
               may be necessary so that, as thereafter delivered to the offerees
               of such securities, such Prospectus shall not include an

                                        5



               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
               then existing;

                    (ix)   make available for inspection by Investor, any
               underwriter participating in any disposition pursuant to such
               Registration Statement and any attorney, accountant or other

               at the Company's expense, to undertake appropriate action to
               prevent disclosure of the Information deemed confidential);

distribute the Registrable Units under the registration statement solely in the
manner described in the registration statement; and (iii) cease distribution of
such Registrable Units pursuant to such registration statement upon receipt of
written notice from the Company that the prospectus covering the Registrable
Units contains any untrue statement of a material fact or omits a material fact
required to be stated therein or necessary to make the statements therein not
misleading.

Persons within the meaning of the Securities Act and each Representative of any
of the foregoing Persons, against any losses, claims, damages or liabilities,
joint or several, to which any of the foregoing Persons may become subject under
the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) are caused by an untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement under which such Registrable Units were registered, any preliminary
Prospectus or final Prospectus contained therein, any amendment or supplement
thereto or any document incident to registration or qualification of any
Registrable Units, or are caused by 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, with respect to any Prospectus, necessary
to make the statements therein in light of the circumstances under which they
were made not misleading, or any violation by the Company of the Securities Act
or state securities or blue sky laws applicable to the Company and relating to
action or inaction required of the Company in connection with such registration
or qualification under such state securities or blue sky laws, and the Company
shall promptly reimburse Investor, such underwriter, such

                                        7



broker, such controlling Person or such Representatives for any reasonable legal
or other expenses incurred by any of them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
                                                             --------  -------
that the Company shall not be liable to any such Person 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 made in
said Registration Statement, preliminary Prospectus, amendment, supplement or
document incident to registration or qualification of any Registrable Units in
reliance upon and in conformity with written information furnished to the
Company by such Person, or a Person duly acting on their behalf, specifically
for use in the preparation thereof; provided further, however, that the
                                    -------- -------  -------
foregoing indemnity agreement is subject to the condition that, insofar as it
relates to any untrue statement, allegedly untrue statement, omission or alleged
omission made in any preliminary Prospectus but eliminated or remedied in the
final Prospectus (filed pursuant to Rule 424 of the Securities Act), such
indemnity agreement shall not inure to the benefit of any indemnified party from
whom the Person asserting any loss, claim, damage, liability or expense
purchased the Registrable Units which are the subject thereof, if a copy of such
final Prospectus had been timely made available to such Indemnified Person and
such final Prospectus was not delivered to such Person with or prior to the
written confirmation of the sale of such Registrable Units to such Person.

               (b) In connection with any registration of Registrable Units
under the Securities Act pursuant to this Agreement, Investor shall indemnify
and hold harmless (in the same manner and to the same extent as set forth in the
paragraph (a) of this Section 6) the Company, each underwriter or broker
involved in such offering, each other seller of Common Units under such
Registration Statement, each Person who controls any of the foregoing Persons
within the meaning of the Securities Act and any Representative of the foregoing
Persons with respect to any statement or omission from such Registration
Statement, any preliminary Prospectus or final Prospectus contained therein, any
amendment or supplement thereto or any document incident to registration or
qualification of any Registrable Units, if such statement or omission was made
in reliance upon and in conformity with written information furnished to the
Company or such underwriter by Investor or a Person duly acting on their behalf
specifically for use in connection with the preparation of such Registration
Statement, preliminary Prospectus, final Prospectus, amendment or supplement;
provided, however, that the maximum amount of liability in respect of such
- --------  -------
indemnification shall be limited to an amount equal to the proceeds actually
received by Investor from the sale of Registrable Units effected pursuant to
such registration.

               (c) Promptly after receipt by an indemnified party of notice of
the commencement of any action involving a claim referred to in the preceding
paragraphs of this Section 6, such indemnified party will, if a claim in respect
thereof is made against an indemnifying party, give written notice to the latter
of the commencement of such action (provided however, that an indemnified
                                    -------- -------
party's failure to give such notice in a timely manner shall only relieve the
indemnification obligations of an indemnifying party to the extent such
indemnifying party is prejudiced by such failure). In case any such action is
brought against an indemnified party, the indemnifying party will be entitled to
participate in and to assume the defense thereof, jointly with any other
indemnifying party similarly notified to the extent that it may wish, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof,

                                        8



the indemnifying party shall not be responsible for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof; provided, however, that if any indemnified party shall have reasonably
         --------  -------
concluded, based upon advice of its counsel, that there may be one or more legal
or equitable defenses available to such indemnified party which are in addition
to or conflict with those available to the indemnifying party, or that such
claim or litigation involves or could have an effect upon matters beyond the
scope of the indemnity agreement provided in this Section 6, the indemnifying
party shall not have the right to assume the defense of such action on behalf of
such indemnified party and such indemnifying party shall reimburse such
indemnified party and any Person controlling such indemnified party for that
portion of the fees and expenses of any one lead counsel (plus appropriate
                                                          ----
special and local counsel) retained by the indemnified party which are
reasonably related to the matters covered by the indemnity agreement provided in
this Section 6.

               (d) If the indemnification provided for in this Section 6 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, claim, damage or liability referred to herein, then
the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amounts paid or payable by such indemnified
party as a result of such loss, claim, damage or liability in such proportion as
is appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other hand in connection with the
statements or omissions which resulted in such loss, claim, damage or liability
as well as any other relevant equitable considerations; provided, however, that
                                                        --------  -------
the maximum amount of liability in respect of such contribution shall be
limited, in the case of each seller of Registrable Units, to an amount equal to
the proceeds actually received by such seller from the sale of Registrable Units
effected pursuant to such registration. The relative fault of the indemnifying
party and of the indemnified party shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

               (e) The indemnification and contribution provided for under this
Agreement will remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party and will survive the Transfer of
securities.

               SECTION 7. Underwriting Agreement.
                          ----------------------

               (a) Notwithstanding the provisions of Sections 3 and 6, to the
extent that Investor shall enter into an underwriting or similar agreement,
which agreement contains provisions covering one or more issues addressed in
such Sections of this Agreement, the provisions contained in such Sections of
this Agreement addressing such issue or issues shall be of no force or effect
with respect to such registration, but this provision shall not apply to the
Company if the Company is not a party to the underwriting or similar agreement.

               (b) Investor may not participate in any registration hereunder
that is underwritten unless Investor agrees to (i) sell Investor's Registrable
Units proposed to be included therein on the basis provided in any underwriting
arrangements acceptable to the

                                        9



Company and Investor and (ii) as expeditiously as possible, notify the Company
of the occurrence of any event concerning Investor as a result of which the
Prospectus relating to such registration contains an untrue statement of a
material fact or omits to state 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.

              SECTION 8.  Suspension. Anything contained in this Agreement to
                          ----------
the contrary notwithstanding, the Company may (not more than once with respect
to each registration), by notice in writing to Investor, require Investor to
suspend, for up to 90 days (the "Suspension Period"), the use of any Prospectus
                                 -----------------
included in a Registration Statement filed under Section 2 if a Material
Transaction exists that would require an amendment to such Registration
Statement or supplement to such Prospectus (including any such amendment or
supplement made through incorporation by reference to a report filed under
Section 13 of the Exchange Act). The period during which such Prospectus must
remain effective shall be extended by a period equal to the Suspension Period.
The Company may (but shall not be obligated to) withdraw the effectiveness of
any Registration Statement subject to this provision.

              SECTION 9.  Information by Investor. Investor shall furnish to the
                          -----------------------
Company and the managing underwriter such written information regarding Investor
and the distribution proposed by Investor as the Company or the managing
underwriter may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification or compliance
referred to in this Agreement.

              SECTION 10. Exchange Act Compliance. From and after the
                          -----------------------

Company pursuant to the Exchange Act relating to any class of the Company's
securities shall have become effective, the Company shall comply with all of the
reporting requirements of the Exchange Act (whether or not it shall be required
to do so) and shall comply with all other public information reporting
requirements of the Commission which are conditions to the availability of Rule
144 for the sale of the Common Units. The Company shall cooperate with Investor
in supplying such information as may be necessary for Investor to complete and
file any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of Rule 144.

              SECTION 11. No Conflict of Rights. The Company represents and
                          ---------------------
warrants to Investor that the registration rights granted to Investor hereby do
not conflict with any other registration rights granted by the Company. The
Company shall not, after the date hereof, grant any registration rights which
conflict with or impair, or have any priority over, the registration rights
granted hereby. In any underwritten Public Offering, the managing underwriter
shall be a nationally recognized investment banking firm selected by the
Company, and reasonably acceptable to Investor if Investor would have the right
(prior to giving effect to any cutbacks) to include Registrable Units in such
Public Offering.

              SECTION 12. Termination. This Agreement shall terminate and be of
                          -----------
no further force or effect when there shall not be any Registrable Units;

- -------- -------
Agreement.

                           -------------
hereunder to any purchaser from such Investor of Restricted Securities.

               SECTION 15. Entire Agreement. This Agreement contains the entire
                           ----------------
agreement among the parties with respect to the subject matter hereof and
supersedes all prior agreements and understandings with respect hereto, all of
which are hereby terminated in their entirety and of no further force or effect.

                                       11



               SECTION 18. Headings. The headings of the various sections of
                           --------
this Agreement have been inserted for convenience of reference only and shall
not be deemed to be a part of this Agreement.

               SECTION 19. Severability. It is the desire and intent of the
                           ------------
parties that the provisions of this Agreement be enforced to the fullest extent
permissible under the law and public policies applied in each jurisdiction in
which enforcement is sought. Accordingly, if any provision of this Agreement
would be held in any jurisdiction to be invalid, prohibited or unenforceable for
any reason, such provision, as to such jurisdiction, shall be ineffective,
without invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of such provision in any other jurisdiction.
Notwithstanding the foregoing, if such provision could be more narrowly drawn so
as not to be invalid, prohibited or unenforceable in such jurisdiction, it
shall, as to such jurisdiction, be so narrowly drawn, without invalidating the
remaining provisions of this Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction.

Delaware, without giving effect to any choice or conflict of law provision or
rule (whether in the State of Delaware or any other jurisdiction) that would
cause the application of the laws of any jurisdiction other than the State of
Delaware. In furtherance of the foregoing, the internal law of the State of
Delaware will control the interpretation and construction of this Agreement,
even if under such jurisdiction's choice of law or conflict of law analysis, the
substantive law of some other jurisdiction would ordinarily apply.

               SECTION 21. Counterparts; Validity. This Agreement may be
                           ----------------------
executed in any number of counterparts, each of which shall be an original, but
