<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;4.03 <U>Investment</U>. The Purchased Units are being acquired for such Purchaser&#146;s own
account, or the accounts of clients for whom such Purchaser exercises discretionary investment
authority, not as a nominee or agent, and with no present intention of distributing the Purchased
Units or any part thereof, and such Purchaser has no present intention of selling or granting any
participation in or otherwise distributing the same in any transaction in violation of the
securities Laws of the United States of America or any state, without prejudice, however, to such
Purchaser&#146;s right at all times to sell or otherwise dispose of all or any part of the Purchased
Units under a registration statement under the Securities Act and applicable state securities laws
or under an exemption from such registration available thereunder (including, without limitation,
if available, Rule&nbsp;144 promulgated thereunder). If such Purchaser should in the future decide to
dispose of any of the Purchased Units, such Purchaser understands and agrees (a)&nbsp;that it may do so
only (i)&nbsp;in compliance with the Securities Act and applicable state securities law, as then in
effect, or (ii)&nbsp;in the manner contemplated by any registration statement pursuant to which such
securities are being offered, and (b)&nbsp;that stop-transfer instructions to that effect will be in
effect with respect to such securities. Notwithstanding the foregoing, subject to <U>Section
8.04(c)</U>, any Purchaser may at any time enter into one or more total return swaps with respect
to such Purchaser&#146;s Purchased Units with a third party or transfer Purchased Units to an Affiliate
of such Purchaser provided that any such transaction is exempt from registration under the
Securities Act and is otherwise in compliance with all applicable securities laws.

(b)&nbsp;it is a &#147;qualified institutional buyer&#148; (within the meaning of Rule&nbsp;144A under the Securities
Act), (c)&nbsp;by reason of its business and financial experience it has such knowledge, sophistication
and experience in business and financial matters so as to be capable of evaluating the merits and
risks of the prospective investment in the Purchased Units, is able to bear the economic risk of
such investment and, at the present time, would be able to afford a complete loss of such

receive answers from Representatives of the Partnership regarding such matters, including with
respect to the Drop Down.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;4.06 <U>Restricted Securities</U>. Such Purchaser understands that the Purchased Units it
is purchasing are characterized as &#147;restricted securities&#148; under the federal securities Laws
inasmuch as they are being acquired from the Partnership in a transaction not involving a public
offering and that under such Laws and applicable regulations such securities may be resold without
registration under the Securities Act only in certain limited circumstances. In this connection,
such Purchaser represents that it is knowledgeable with respect to Rule&nbsp;144 of the Commission
promulgated under the Securities Act.

the Purchase Price is less than the trading price of the Common Units on NASDAQ as of the Closing
Date, the General Partner intends to specially allocate items of book and taxable income to the
Purchasers so that their capital accounts in their Common Units are consistent, on a per-unit
basis, with the capital accounts of the other holders of Common Units (and thus to assure
fungibility of all Common Units). Such special allocation will occur upon the earlier to occur of
any taxable period of the Partnership ending upon, or after, (i)&nbsp;a book-up event or book-down event
in accordance with Treasury Regulation&nbsp;Section&nbsp;1.704-1(b)(2)(iv)(f) or a sale of all or
substantially all of the assets of the Partnership occurring after the date of the issuance of the
Common Units or (ii)&nbsp;a transfer by a Purchaser of Common Units to a Person that is not an Affiliate
of the holder. A Purchaser holding a Common Unit shall be required to provide notice to the
General Partner of the transfer of a Common Unit to a Person that is not an Affiliate of the
Purchaser no later than the last Business Day of the calendar year during which such transfer
occurred, unless by virtue of the application of clause (i)&nbsp;above, the General Partner has
determined that the Common Units transferred are consistent, on a per-unit basis, with the capital
accounts of the other holders of Common Units.

takes the position that coverage of short sales of securities &#147;against the box&#148; prior to the
effective date of a registration statement is a violation of Section&nbsp;5 of the Securities Act. Each
Purchaser agrees, severally and not jointly, that it will not engage in any Short Sales that result
in the disposition of the Purchased Units acquired hereunder by the Purchaser until such time as
the Registration Statement (as defined in the Registration Rights Agreement) is declared effective;

the Partnership or its Subsidiaries by the Participating Unit. No Purchaser makes any

Registration Statement under the Securities Act with respect to all of the Registrable Securities.
The Partnership shall use its commercially reasonable efforts to cause the Shelf Registration
Statement to become effective no later than 270&nbsp;days after the date of the Closing. The Partnership
will use its commercially reasonable efforts to cause the Shelf Registration Statement filed

constitute such an offering and that permits the continuous resale at the market by the Holders
participating therein (or as otherwise may be acceptable to each Holder) without being named
therein as an &#147;underwriter,&#148; then the Partnership shall reduce the number of Registrable Securities
to be included in the Shelf Registration Statement by all Holders until such time as the Commission

be included by all Holders on a pro rata basis (based upon the number of Registrable Securities
otherwise required to be included for each Holder) unless the inclusion of Registrable Securities
by one or more particular Holders is resulting in the Commission&#146;s position that the offering is
being made &#147;by or on behalf of the Company,&#148; in which event the Registrable Securities held by such
Holder(s) shall be the only Registrable Securities subject to reduction (and, if by more than one
Holder, on a pro rata basis by such Holders or on such other basis as would result in the exclusion

reduce the total number of Registrable Securities to be registered on behalf of such Holder, until

which is a part of the Shelf Registration Statement (in which event the Selling Holder shall

effect and shall take such other actions to permit registered sales of Registrable Securities as
contemplated in this Agreement.

Securities for sale for the benefit of the Holders will have a material adverse effect on the
price, timing or distribution of the Common Units in the Underwritten Offering, then the amount of
Registrable Securities to be offered for the accounts of Holders shall be determined based on the
provisions of <U>Section&nbsp;2.02(b)</U>. The notice required to be provided in this <U>Section

Each such Holder shall then have three Business Days after receiving such notice to request
inclusion of Registrable Securities in the Underwritten Offering, except that such Holder shall
have one Business Day after such Holder confirms receipt of the notice to request inclusion of
Registrable Securities in the Underwritten Offering in the case of a &#147;bought deal&#148; or &#147;overnight
transaction&#148; where no preliminary prospectus is used. If no request for inclusion from a Holder is
received within the specified time, each such Holder shall have no further right to participate in
such Underwritten Offering. If, at any time after giving written notice of its intention to
undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, the

held by a court or government agency of competent jurisdiction to be unavailable to any indemnified
party or is insufficient to hold them harmless in respect of any Losses, then each such
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 Loss in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one hand and of such
indemnified party on the other in connection with the statements or omissions which resulted in
such Losses, as well as any other relevant equitable considerations; <I>provided, however</I>, that in no
event shall such Selling Holder be required to contribute an aggregate amount in excess of the
dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale
of Registrable Securities giving rise to such indemnification. The relative fault of the
indemnifying party on the one hand and the indemnified party on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact has been made by, or relates to,
information supplied by such party, and the parties&#146; relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission. The parties hereto
agree that it would not be just and equitable if contributions pursuant to this paragraph were to
be determined by pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to herein. The amount paid by an indemnified
party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed
to include any legal and other expenses reasonably incurred by such indemnified party in connection
with investigating or defending any Loss which is the subject of this paragraph. No person guilty
of fraudulent misrepresentation (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.
