If Purchaser should in the future decide to dispose of any of the Purchased Units, Purchaser understands and agrees that it may do so only (a)(i) in compliance with the Securities Act and applicable state securities Law, as then in effect, or pursuant to an exemption therefrom (including Rule 144 under the Securities Act) or (ii) in the manner contemplated by any registration statement pursuant to which such securities are being offered, and (b) if no stop-transfer instructions will be in effect with respect to such securities.

Section 4.04 Nature of Purchaser. Purchaser represents and warrants to, and covenants and agrees with, Atlas that (a) it is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated by the Commission pursuant to the Securities Act and (b) 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 Securities, 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 investment.

Section 4.05 Receipt of Information; Authorization. Purchaser acknowledges that it has (a) had access to the Atlas SEC Documents, (b) had access to information regarding the Acquisition and its potential effect on Atlas’s operations and financial results and (c) been provided a reasonable opportunity to ask questions of and receive answers from Representatives of Atlas regarding such matters.

Section 4.06 Restricted Securities. Purchaser understands that the Purchased Securities it is purchasing are characterized as “restricted securities” under the federal securities Laws inasmuch as they are being acquired from Atlas 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 connection with the foregoing, Purchaser represents that it is knowledgeable with respect to Rule 144 of the Commission promulgated under the Securities Act.

Section 4.07 Certain Fees. No fees or commissions will be payable by Purchaser to brokers, finders or investment bankers with respect to the sale of any of the Purchased Securities or the consummation of the transactions contemplated by this Agreement. Atlas will not be liable for any such fees or commissions. Purchaser agrees that it will indemnify and hold harmless Atlas from and against any and all claims, demands or liabilities for broker’s, finder’s, placement or other similar fees or commissions incurred by Purchaser or alleged to have been incurred by Purchaser in connection with the purchase of Purchased Securities or the consummation of the transactions contemplated by this Agreement.

Section 4.08 Legend. The Purchased Securities (other than the Warrants) shall not be evidenced by physical certificates. It is understood that the certificates evidencing the Warrants and, if any certificates are issued for the other Purchased Securities, such certificates initially will bear the following legend:

“These securities have not been registered under the Securities Act of 1933, as amended. These securities may not be sold, offered for sale, pledged (except in connection with a bona fide margin account or other loan or financing arrangement secured by these securities) or hypothecated in the absence of a registration statement in effect with respect to the securities under such Act or pursuant to an exemption from registration thereunder and, in the case of a transaction exempt from registration, unless sold pursuant to Rule 144 under such Act or the issuer has received documentation reasonably satisfactory to it that such transaction does not require registration under such Act.”

Section 4.09 Short Selling. Purchaser represents that it has not entered into any Short Sales of any of the securities of Atlas owned by it between the time it first began discussions with Atlas about the transactions contemplated by this Agreement and the date hereof.

Section 4.10 Receipt of Information. The Purchaser (a) has carefully reviewed the Atlas SEC Documents and has been furnished with all other materials that it considers relevant to an investment in the Purchased Securities, has had a full opportunity to ask questions of and receive answers from Atlas or any person or persons acting on behalf of Atlas concerning the terms and conditions of an investment in the Purchased Securities; (b) has conducted, to the extent it

deemed necessary, an independent investigation of such matters as, in its judgment, is necessary for it to make an informed investment decision with respect to the Purchased Securities and Atlas; (c) is not relying upon, and has not relied upon, any statement, representation or warranty made by any person except for the statements, representations and warranties contained in this Agreement and the Atlas SEC Documents; and (d) has made all decisions in connection with the offer and sale of the Purchased Securities as the result of arm’s-length negotiations.

INDEMNIFICATION, COSTS AND EXPENSES

Section 7.01 Indemnification by Atlas. Atlas agrees to indemnify Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay and reimburse each of them for all costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of or in any way related to (i) any actual or proposed use by Atlas of the proceeds of the sale of the Purchased Units or (ii) the breach of any of the representations, warranties or covenants of Atlas contained herein; provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of such representation or warranty.

Section 7.02 Indemnification by Purchaser. Purchaser agrees to indemnify Atlas and its Representatives (collectively, “Atlas Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay and reimburse each of them for all costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of or in any way related to the breach of any of the representations, warranties or covenants of Purchaser contained herein.

Section 7.03 Indemnification Procedure. Promptly after any Atlas Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action or proceeding by a third party, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature

and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition 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, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense 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. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, involves no admission of wrongdoing or malfeasance by, and includes a complete release from liability of, the Indemnified Party.

Except as expressly permitted by this Section 8.04(c), such rights and obligations may not otherwise be transferred except with the prior written consent of Atlas (which consent shall not be unreasonably withheld), in which case the assignee shall be deemed to be a Purchaser hereunder with respect to such assigned rights or obligations and shall agree to be bound by the provisions of this Agreement.

Subject to the Limited Partnership Agreement, the legend described in Section 4.08 shall be removed and Atlas shall issue a certificate without such legend to the holder of Purchased Units, or shall instruct the transfer agent to remove such legend from the book-entry position evidencing the Purchased Units, if, unless otherwise required by state securities Laws, (i) such Purchased Units are sold pursuant to an effective registration statement, (ii) in connection with a sale, assignment or other transfer, such holder provides Atlas with an opinion of a law firm reasonably acceptable to Atlas, in a generally acceptable form, to the effect that such sale, assignment or transfer of such Purchased

(1) complete and manually sign the “Notice of Optional Conversion” (attached as Exhibit A hereto) or a facsimile thereof;

(2) deliver the completed Notice of Optional Conversion;

(3) if required, furnish appropriate endorsements and transfer documents to the Conversion Agent to the extent that Common Units issued, or cash paid by the Partnership, upon conversion of Preferred Units are to be issued in a name or paid to a Person other than the Holder; and

(4) pay all transfer or similar taxes, if any, required, under Section 8(b).

The date that a Holder satisfies the foregoing requirements, or the requirements set forth in Section 8(b), if applicable, is the “Optional Conversion Date.”

(b) The Partnership shall pay any documentary, stamp or similar issue or transfer taxes that may be payable in respect of any issuance or delivery of Common Units upon conversion of Preferred Unit, other than the transfer taxes payable upon the issuance of Common Units upon conversion of Preferred Units in a name or names other than that of the Holder, which shall be paid by the converting Holder.

(c) Effective immediately prior to 5:00 p.m., New York City time, on the Mandatory Conversion Date or Optional Conversion Date, distributions on the converted Preferred Units shall cease to accrue and the converted Preferred Units shall cease to be outstanding, in each case subject to the right of Holders of such converted Preferred Units to receive the consideration issuable upon conversion which they are entitled to pursuant to Section 7 hereof.

(d) As of 5:00 p.m., New York City time, on the applicable Mandatory Conversion Date or Optional Conversion Date, as applicable, the issuance by the Partnership of Common Units upon conversion of Preferred Units shall become effective and the Person entitled to receive such Common Units shall be treated for all purposes as the record holder or holders of such Common Units. Prior to 5:00 p.m., New York City time, on the applicable Mandatory Conversion Date or Optional Conversion Date, as the case may be, the Common Units issuable upon conversion shall be deemed not outstanding for any purpose, and Holders of Preferred Units shall have no rights with respect to the Common Units issuable upon conversion by virtue of holding Preferred Units.

(e) In connection with the conversion of any Preferred Unit, no fractional Common Units shall be issued to the converting Holder. In lieu of any fractional Common Units issuable to a Holder upon conversion, the Partnership shall pay or deliver, as applicable, to the converting Holder, at its option, either (i) a number of Common Units rounded up to the next whole number of units, or (ii) an amount in cash (computed to the nearest cent) equal to the product of that same fraction and the Closing Price of Common Units on the Trading Day immediately preceding the Mandatory Conversion Date or Optional Conversion Date, as applicable.

(f) If more than one Preferred Unit shall be surrendered for conversion at one time by or for the same Holder, the number of Common Units issuable upon conversion of those Preferred Units shall be computed on the basis of the aggregate number of Preferred Units so surrendered.

(g) (i) With respect to any conversion of Preferred Units prior to the Mandatory Conversion Date,

(1) promptly following the Optional Conversion Date, the Partnership shall instruct the Conversion Agent to deliver or cause to be delivered to the converting Holder confirmation by book entry of the whole number of Common Units issued upon conversion of such Preferred Units; and

(2) on the Business Day immediately following the Partnership Optional Conversion Date, the Partnership shall deliver or cause to be delivered to the converting Holder any cash payment for any fractional units that the Partnership is obligated to pay under Section 8(e).

(ii) With respect to the mandatory conversion of Preferred Units under Section 7(a),

(1) promptly following the Mandatory Conversion Date, the Partnership shall instruct the Conversion Agent to deliver or cause to be delivered to the converting Holder confirmation by book entry of the whole number of Common Units issued upon conversion of such Preferred Units, and

(2) on the Business Day immediately following the Mandatory Conversion Date, the Partnership shall deliver or cause to be delivered to the converting Holder any cash payment for any fractional units that the Partnership is obligated to pay under Section 8(e).

9. Conversion Rate Adjustments. The Conversion Rate shall be adjusted from time to time by the Partnership in accordance with the provisions of this Section 9.

(a) If the Partnership issues Common Units as a distribution to all or substantially all holders of Common Units, or if the Partnership effects a split or combination of Common Units, the Conversion Rate shall be adjusted based on the following formula:

CR₁ = CR₀ × OS₁ / OS₀

where,

CR₀ = the Conversion Rate in effect immediately prior to the adjustment relating to such event;

CR₁ = the new Conversion Rate in effect taking such event into account;

OS₀ = the number of Common Units outstanding immediately prior to the effective time of the adjustment relating to such event; and

OS₁ = the number of Common Units outstanding immediately after the effective time of the adjustment relating to such event (giving effect to such distribution, split or share combination, as applicable, as of such effective time).

Any adjustment made pursuant to this Section 9(a) shall become effective immediately after 5:00 p.m., New York City time, on the Record Date or the effective date of such split or combination, as applicable. If any distribution of the type described in this Section 9(a) is not so paid or made, or the outstanding Common Units are not split or combined, as the case may be, the new Conversion Rate shall be immediately readjusted, effective as of the date the General Partner determines not to pay such distribution or to effect such split or combination, to the Conversion Rate that would then be in effect if such distribution, split or combination had not been announced.

(b) If the Partnership issues to all or substantially all holders of Common Units any rights, warrants, options or other securities entitling them to subscribe for or purchase Common Units, or if the Partnership issues to all holders of Common Units securities convertible into Common Units, in either case at an exercise price per Common Unit or a conversion price per Common Unit less than the volume-weighted average of the Closing Prices of Common Units over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-distribution Date for such issuance, the Conversion Rate shall be adjusted based on the following formula:

CR₁ = CR₀ × (OS₀ + X) / (OS₀ + Y)

where,

CR₀ = the Conversion Rate in effect immediately prior to the adjustment relating to such event;

CR₁ = the new Conversion Rate in effect taking such event into account;

OS₀ = the number of Common Units outstanding immediately prior to the effective time of the adjustment relating to such event;

X = the total number of Common Units issuable pursuant to such rights, warrants, options, convertible securities or other securities; and

Y = the number of Common Units equal to the quotient of (A) the aggregate price payable to exercise such rights, warrants, options, convertible securities or other securities and (B) the average of the Closing Prices of Common Units over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-distribution Date for such issuance.

Any adjustment made pursuant to this Section 9(b) shall become effective immediately after 5:00 p.m., New York City time, on the Record Date. For purposes of this Section 9(b), in determining whether any rights, warrants, options, convertible securities or other securities entitle the holders of Common Units to subscribe for or purchase, or exercise a conversion right for, Common Units at less than the applicable average of the Closing Prices of Common Units, and in determining the aggregate exercise or conversion price payable for such Common Units, there shall be taken into account any consideration the Partnership receives for such rights, warrants, options, convertible securities or other securities and any amount payable on exercise or conversion thereof, with the value of such consideration, if other than cash, to be determined by the General Partner in good faith. If any rights, warrants, options, convertible securities or other securities described in this Section 9(b) are not so issued, the Conversion Rate shall be readjusted, effective as of the date the General Partner publicly announces its decision not to issue such rights, warrants, options, convertible securities or other securities, to the Conversion Rate that would then be in effect without such issuance. If any rights, warrants, options, convertible securities or other securities described in this Section 9(b) are not exercised or converted prior to the expiration of the exercisability or convertibility thereof, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if

the adjustments made upon the issuance of such right, warrant, option, convertible security or other securities had been made on the basis of the delivery of only the number of Common Units actually delivered.

(c) (i) If the Partnership distributes evidences of its indebtedness or its other assets or property to all or substantially all holders of Common Units, excluding:

(A) distributions, rights, warrants, options, convertible securities or other securities as to which an adjustment was effected pursuant to Section 9(a) or (b) hereof,

(B) distributions paid exclusively in cash, and

then the Conversion Rate shall be adjusted based on the following formula:

CR₁ = CR₀ × SP₀ / (SP₀ – FMV)

where,

CR₀ = the Conversion Rate in effect immediately prior to the adjustment relating to such event;

CR₁ = the new Conversion Rate taking such event into account;

SP₀ = the average of the Closing Prices of Common Units over the ten consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-distribution Date for such distribution; and

FMV = the Fair Market Value (as determined by the General Partner in good faith) of the evidences of indebtedness, assets or property distributed with respect to each outstanding Common Unit as of the Ex-distribution Date for such distribution.

An adjustment to the Conversion Rate made pursuant to this Section 9(c)(i) shall be made successively whenever any such distribution is made and shall become effective immediately after 5:00 p.m., New York City time, on the Record Date.

(ii) If the Partnership distributes, to all holders of Common Units, common units of any class or series or any similar equity interest of or relating to a Subsidiary or other business unit of the Partnership, and such units or equity interests are listed for trading on a U.S. national securities exchange (a “Spin-off”), the Conversion Rate shall be adjusted based on the following formula:

CR₁ = CR₀ × (FMV₀ + MP₀) / MP₀

where,

CR₀ = the Conversion Rate in effect immediately prior to the adjustment relating to such event;

CR₁ = the new Conversion Rate taking such event into account;

FMV₀ = the average of the Closing Prices of the equity interest distributed to holders of Common Units applicable to one Common Unit over the first ten consecutive Trading Day period commencing on, and including, the Trading Day following the effective date of such Spin-off (such period, the “Valuation Period”); and

MP₀ = the average of the Closing Prices of Common Units over the Valuation Period.

If the application of the foregoing formula would result in a decrease in a fixed conversion rate, no adjustment to the Conversion Rate shall be made. An adjustment to the Conversion Rate made pursuant to this Section 9(c)(ii) shall occur on the final Trading Day of the Valuation Period; provided, that in respect of any conversion of Preferred Units within the ten consecutive Trading Days immediately following the date of the Spin-off, references with respect to the Spin-off to “ten consecutive Trading Day period” shall be deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such Spin-off and the Mandatory Conversion Date or Optional Conversion Date, as applicable, in determining the Conversion Rate.

(iii) If any such distribution or distribution described in this Section 9(c) is not paid or made, the new Conversion Rate shall be readjusted, effective as of the date the General Partner publicly announces its decision not to pay such distribution or distribution, to the Conversion Rate that would then be in effect without such distribution or distribution.

(d) If the Partnership or any Subsidiary makes a payment in respect of a tender or exchange offer for Common Units (other than a tender offer solely to holders of fewer than 100 Common Units), to the extent that the cash and value of any other consideration included in the payment per Common Unit exceeds the average of the Closing Prices of Common Units over the ten consecutive Trading Day period commencing on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Conversion Rate shall be adjusted based on the following formula:

CR₁ = CR₀ × (AC + (SP₁ × OS₁)) / (SP₁ × OS₀)

where,

CR₀ = the Conversion Rate in effect immediately prior to the adjustment relating to such event;

CR₁ = the new Conversion Rate taking such event into account;

AC = the Fair Market Value (as determined by the General Partner in good faith), on the Expiration Date, of the aggregate value of all cash and any other consideration paid or payable for units accepted for purchase or exchange in such tender or exchange offer;

OS₀ = the number of Common Units outstanding immediately prior to the Expiration Date (prior to giving effect to such tender offer or exchange offer);

OS₁ = the number of Common Units outstanding immediately after the Expiration Date (after giving effect to such tender offer or exchange offer); and

SP₁ = the average of the Closing Prices of Common Units over the ten consecutive Trading Day period commencing on the Trading Day next succeeding the Expiration Date (such period, the “Tender Offer Valuation Period”).

If the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made. Any adjustment to the Conversion Rate made pursuant to this Section 9(d) shall become effective immediately after 5:00 p.m., New York City time, on the final Trading Day of the Tender Offer Valuation Period; provided, that in respect of any conversion within the ten consecutive Trading Days next succeeding the Expiration Date, references with respect to “ten consecutive Trading Day period” shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Expiration Date and the Mandatory Conversion Date, Optional Conversion Date or Reorganization Event Conversion Date, as applicable, in determining the Conversion Rate.

If the Partnership or one of its Subsidiaries is obligated to purchase Common Units pursuant to any such tender or exchange offer, but the Partnership, or such Subsidiary, is permanently prevented by applicable law from effecting any such purchase, or all such purchases are rescinded, then the new Conversation Rate shall be readjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made.

(e) Notwithstanding the provisions of this Section 9, no adjustment to the Conversion Rate shall be made if Holders may participate in the transaction that would otherwise give rise to such adjustment on an as-converted basis and without converting their Preferred Units.

(f) Notwithstanding the provisions of this Section 9, no adjustment to the Conversion Rate need be made if the Common Units to be issued upon conversion will actually receive the consideration provided in, or be subject to, the transaction or event that would otherwise trigger the adjustment.

(g) No adjustment to the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least one percent (1%) of the Conversion Rate then in effect; provided, that any adjustments that by reason of this Section 9(g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 9 shall be made by the Partnership and

shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000th) of a unit, as the case may be. Notwithstanding the foregoing, all adjustments not previously made shall have effect with respect to any conversion of Preferred Units.

(h) To the fullest extent permitted by law, the Partnership may (but is not required to) make such increases in the Conversion Rate, in addition to those required by this Section 9, as the General Partner considers to be advisable to avoid or diminish any income tax to holders of Common Units or rights to purchase Common Units resulting from any distribution or distribution of Common Units (or rights or warrants to acquire Common Unit) or from any event treated as such for income tax purposes. To the fullest extent permitted by applicable law, the Partnership from time to time may (but is not required to) increase the Conversion Rate by any amount for any period of time if the period is at least 20 days and the increase is irrevocable during the period and the General Partner determines in good faith that such increase would be in the best interest of the Partnership, which determination shall be conclusive.

(i) If the Partnership shall be required to withhold taxes on constructive distributions to a Holder and the Partnership pays the applicable withholding taxes, the Partnership may, at its option, set off any such payment against cash, Common Units or other assets distributable or payable to such Holder.

(j) Whenever the Conversion Rate is adjusted as herein provided, the Partnership shall promptly file with the Conversion Agent an Officer’s certificate setting forth the Conversion Rate after such adjustment and a brief statement setting forth in reasonable detail the method by which the adjustment to the Conversion Rate was determined. Unless and until a responsible officer of the Conversion Agent shall have received such Officer’s certificate, the Conversion Agent shall not be deemed to have knowledge of any adjustment of the Conversion Rates and may assume that the last Conversion Rates of which it has knowledge are still in effect. Promptly after delivery of such certificate, the Partnership shall prepare a notice of such adjustment of Conversion Rates setting forth the adjusted Conversion Rates and the date on which each adjustment becomes effective and shall promptly mail such notice of adjustment of the Conversion Rate to each Holder at its last address appearing in the Unit register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

10. Conversion Upon Certain Reorganization Events. If an event described in Section 11(a) is anticipated to occur in which the Partnership is not the surviving entity, then the Partnership may, at its option, cause the conversion of all, but not less than all, outstanding Preferred Units (the “Reorganization Event Conversion”). The Reorganization Event Conversion shall occur on the effective date of such Reorganization Event (the “Reorganization Event Conversion Date”). If the Partnership exercises this option, each Holder of the Preferred Units shall receive the Reference Property. In order for the Partnership to exercise its option for a Reorganization Event Conversion, the Partnership must provide written notice to the Holders not later than 30 days prior to the anticipated effective date of the Reorganization Event.

11. Effect of Reclassification, Consolidation, Merger or Sale on Conversion.

(a) Subject to the Partnership’s right to convert the Preferred Units under Section 10, in the event of:

(i) any consolidation, merger or combination of the Partnership with or into another Person (other than a merger or consolidation in which the Partnership is the continuing Partnership and in which the Common Units outstanding immediately prior to the merger or consolidation are not exchanged for cash, securities or other property of the Partnership or another Person);

(ii) any sale, transfer, lease or conveyance of all or substantially all of the properties and assets of the Partnership to any other person; or

(iii) any statutory exchange of the Partnership’s securities with another Person (other than in connection with a merger or acquisition covered by clause (i) above),

in each case where Common Units are exchanged for, or converted into, stock, securities, property or assets (including cash or any combination thereof) (a “Reorganization Event”), each Preferred Unit outstanding immediately prior to such Reorganization Event shall, without the consent of the Holder, become convertible into the kind of securities, cash and other property that such Holder would have been entitled to receive if such Holder had converted its Preferred Units into Common Units immediately prior to such Reorganization Event (the “Reference Property”). In such event, on the Reorganization Event Conversion Date, the applicable Conversion Rate then in effect shall be applied to determine the amount and value of securities, cash or property a Holder would have received in such transaction (without interest thereon and without any right to distributions thereon which have a Record Date prior to the date such Preferred Units are actually converted).

(b) Subject to the notice requirements of Section 10 regarding certain transactions as set forth in Section 11(a), the Partnership shall cause notice of the application of this Section 11 to be delivered to each Holder at the address of such Holder within twenty (20) days after the occurrence of any of the events specified in Section 11(a). Failure to deliver such notice shall not affect the legality or validity of any conversion pursuant to this Section 11.

(c) The above provisions of this Section 11 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances, provided, that if Section 10 applies to any event or occurrence, this Section 11 shall not apply to such event or occurrence.

12. Notices. The Partnership shall distribute to the Holders of Preferred Units copies of all notices, materials, annual and quarterly reports, proxy statements, information statements and any other documents distributed generally to the holders of Common Units of the Partnership, at such times and by such method as such documents are distributed to such holders of such Common Units.

13. No Reissuance. No Preferred Units acquired by the Partnership by reason of redemption, purchase, conversion or otherwise shall be reissued.

14. Transfers. No Preferred Unit shall be transferable by any Holder of Preferred Units, except in compliance with all federal and applicable state securities laws. Prior to any transfer, and as a condition thereto, the General Partner may require such documentation, including appropriate opinions of legal counsel, as it, in its sole discretion, deems necessary.

15. Severability of Provisions. If any right, preference or limitation of the Preferred Units set forth in this Certificate of Designation (as this Certificate of Designation may be amended from time to time) is invalid, unlawful or incapable of being enforced by reason of any rule or law or public policy, all other rights, preferences and limitations set forth in this Certificate of Designation, which can be given effect without the invalid, unlawful or unenforceable right, preference or limitation shall nevertheless remain in full force and effect, and no right, preference or limitation herein set forth be deemed dependent upon any such other right, preference or limitation unless so expressed herein.

Section 2. Exercise of Warrant.

(a) Subject to the terms and conditions hereof, Warrants may be exercised by the Holder, in whole or in part, at any time on any Business Day on or after the opening of business on the Warrant Date and prior to 11:59 P.M. New York Time on the Expiration Date by (i) delivery of a written notice, in the form attached as Exhibit A hereto (the “Exercise Notice”), of such holder’s election to exercise his Warrants, which notice shall specify the number of Warrant Units to be purchased and, (ii) payment to the Partnership of an amount equal to the Warrant Exercise Price multiplied by the number of Warrant Units as to which his Warrant is being exercised (the “Aggregate Exercise Price”) by wire transfer of immediately available funds (or by check if the Partnership has not provided the holder with wire transfer instructions for such payment). In the event of any exercise of the rights represented by the Warrant in compliance with this Section 2(a), the Partnership shall on the second (2^nd) Business Day (the “Warrant Unit Delivery Date”) following the date of its receipt of the later of the Exercise Notice and the Aggregate Exercise Price (the “Exercise Delivery Documents”), issue the Warrant Units to which the Holder shall be entitled by registering such Warrant Units in the name of the Holder or its designee upon the books and records of the Partnership, the number of Common Units to which the Holder shall be entitled. Upon the later of the date of delivery of (x) the Exercise Notice and (y) the Aggregate Exercise Price referred to in clause (ii) above, a Holder of Warrants shall be deemed for all purposes to have become the Holder of record of the Warrant Units with respect to which his Warrant has been exercised (the date thereof being referred to as the “Deemed Issuance Date”), irrespective of the date of delivery of the Warrant Units. In the case of a dispute as to the determination of the Warrant Exercise Price, or the arithmetic calculation of the number of Warrant Units, the Partnership shall promptly issue to the

Holder the number of Warrant Units that is not disputed and shall submit the disputed determinations or arithmetic calculations to the Holder via facsimile within two (2) Business Days of receipt of the Holder’s Exercise Notice. If the Holder and the Partnership are unable to agree upon the determination of the Warrant Exercise Price, or arithmetic calculation of the number of Warrant Units within one (1) Business Day of such disputed determination or arithmetic calculation being submitted to the Holder, then the Partnership shall promptly submit via facsimile (i) the disputed determination of the Warrant Exercise Price to an independent, reputable investment banking firm agreed to by the Partnership and the Holder of the Warrant or (ii) the disputed arithmetic calculation of the number of Warrant Units to its independent, outside public accountant. The Partnership shall direct the investment banking firm or the accountant, as the case may be, to perform the determinations or calculations and notify the Partnership and the Holder of the results no later than two (2) Business Days after the date it receives the disputed determinations or calculations. Such investment banking firm’s or accountant’s determination or calculation, as the case may be, shall be deemed conclusive absent demonstrable error.

(b) If this Warrant is submitted for exercise, as may be required by Section 2(d), and unless the rights represented by this Warrant shall have expired or shall have been fully exercised, the Partnership shall, as soon as practicable and in no event later than four (4) Business Days after receipt of this Warrant (the “Warrant Delivery Date”) and at its own expense, issue a new Warrant identical in all respects to this Warrant except it shall represent rights to purchase the number of Warrant Units purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Units with respect to which such Warrant is exercised.

(c) No fractional Common Units are to be issued upon the exercise of this Warrant, but rather the number of Common Units issued upon exercise of this Warrant shall be rounded up or down to the nearest whole number (with 0.5 rounded up).

(d) Book-Entry. Notwithstanding anything to the contrary set forth herein, upon exercise of this Warrant in accordance with the terms hereof, the Holder shall not be required to physically surrender this Warrant to the Partnership unless it is being exercised for all of the Warrant Units represented by the Warrant. The Holder and the Partnership shall maintain records showing the number of Warrant Units exercised and issued and the dates of such exercises or shall use such other method, reasonably satisfactory to the Holder and the Partnership, so as not to require physical surrender of this Warrant upon each such exercise. In the event of any dispute or discrepancy, such records of the Partnership establishing the number of Warrant Units to which the Holder is entitled shall be controlling and determinative in the absence of demonstrable error. Notwithstanding the foregoing, if this Warrant is exercised as aforesaid, the Holder may not transfer this Warrant unless the holder first physically surrenders this Warrant to the Partnership, whereupon the Partnership will forthwith issue and deliver upon the order of the Holder a new Warrant of like tenor, registered as the holder may request, representing in the aggregate the remaining number of Warrant Units represented by this Warrant. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following exercise of any portion of this Warrant, the number of Warrant Units represented by this Warrant may be less than the number stated on the face hereof. Each Warrant shall bear the following legend:

ANY TRANSFEREE OF THIS WARRANT SHOULD CAREFULLY REVIEW THE TERMS OF THIS WARRANT, INCLUDING SECTION 2(d) HEREOF. THE SECURITIES REPRESENTED BY THIS WARRANT MAY BE LESS THAN THE NUMBER SET FORTH ON THE FACE HEREOF PURSUANT TO SECTION 2(d) HEREOF.

Section 3. Covenants. The Partnership hereby covenants and agrees as follows:

(e) This Warrant is, and any Warrants issued in substitution for or replacement of this Warrant will upon issuance be, duly authorized and validly issued.

(f) All Warrant Units that may be issued upon the exercise of the rights represented by the Warrants will, upon issuance, be validly issued, fully paid and nonassessable, subject to applicable provisions of the Delaware Revised Uniform Limited Partnership Act.

(g) During the period within which the rights represented by the Warrant may be exercised, the Partnership will at all times have authorized and reserved a sufficient number of Common Units to provide for the exercise of the rights then represented by the Warrants.

(h) The Partnership shall promptly secure the listing of the Common Units issuable upon exercise of this Warrant on the Principal Market (subject to official notice of issuance upon exercise of this Warrant) and each other market or exchange on which the Common Units are traded or listed and shall maintain, so long as any other Common Units shall be so traded or listed, such listing of all Common Units from time to time issuable upon the exercise of this Warrant; and the Partnership shall so list on the Principal Market and each other market or exchange on which the Common Units are traded or listed and shall maintain such listing of, any other shares of capital stock of the Partnership issuable upon the exercise of this Warrant if and so long as any shares of the same class shall be listed on the Principal Market and each other market or exchange on which the Common Units is traded or listed.

(i) The Partnership will not, by amendment of its Partnership Agreement or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of the Warrants and in the taking of all such action as may reasonably be requested by the Holder of any Warrant in order to protect the exercise privilege of such Holder against impairment, consistent with the tenor and purpose of the Warrants. Without limiting the generality of the foregoing, the Partnership will take all such actions as may be necessary or appropriate in order that the Partnership may validly and legally issue Common Units upon the exercise of any Warrants.

(j) The Warrants will be binding upon any entity succeeding to the Partnership by merger, consolidation or acquisition of all or substantially all of the Partnership’s assets.

Section 4. Taxes. The Partnership shall pay any and all taxes (excluding income taxes, franchise taxes or other taxes levied on gross earnings, profits or the like of Holders of Warrants) that may be payable with respect to the issuance and delivery of Warrant Units upon exercise of Warrants.

Section 5. Holder not deemed a Limited Partner. The Holder, as such, shall not be entitled to vote or receive dividends or be deemed the Holder of Common Units for any purpose solely due to its ownership of the Warrant, nor shall anything contained in the Warrant be construed to confer upon the Holder, as such, any of the rights of a limited partner of the Partnership or any right to vote, give or withhold consent to any Partnership action (whether any reorganization, issue of partnership units or interests, reclassification of partnership units of interests, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive distributions or subscription rights, or otherwise, prior to the Deemed Issuance Date of the Warrant Units that such Holder is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any obligations or liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a Limited Partner of the Partnership, whether such liabilities are asserted by the Partnership or by creditors of the Partnership.

Section 6. Representations of Holder. The holder of this Warrant, by the acceptance hereof, represents that it is acquiring this Warrant, and upon exercise hereof will acquire the Warrant Units, for its own account and not with a view towards, or for resale in connection with, the public sale or distribution of this Warrant or the Warrant Units, except pursuant to sales registered or exempted under the Securities Act; provided, however, that by making the representations herein, the Holder does not agree to hold this Warrant or any of the Warrant Units for any minimum or other specific term and reserves the right to dispose of this Warrant and the Warrant Units at any time in accordance with or pursuant to a registration statement or an exemption under the Securities Act. The Holder further represents, by acceptance hereof, that, as of this date, such holder is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D promulgated by the Securities and Exchange Commission under the Securities Act (an “Accredited Investor”) and has had the opportunity to ask questions and receive answers concerning the Partnership, the Warrant and the offering thereof from the Partnership. Each delivery of an Exercise Notice shall constitute confirmation at such time by the Holder of the representations concerning the Warrant Units set forth in the first two sentences of this Section 6, unless contemporaneous with the delivery of such Exercise Notice, the Holder notifies the Partnership in writing that it is not making such representations (a “Representation Notice”). If the Holder delivers a Representation Notice in connection with an exercise, it shall be a condition to such holder’s exercise of this Warrant and the Partnership’s obligations set forth in Section 2 in connection with such exercise, that the Partnership receive such other representations as the Partnership considers reasonably necessary to assure the Partnership that the issuance of its securities upon exercise of this Warrant shall not violate any United States or state securities laws, and the time periods for the Partnership’s compliance with its obligations set forth in Section 2 shall be tolled until such Holder provides the Partnership with such other representations.

Section 7. Ownership and Transfer.

(a) The Partnership shall maintain at its principal executive offices or at the offices of its transfer agent (or such other office or agency of the Partnership as it may designate by notice to the Holder), a register for this Warrant, in which the Partnership shall record the name and address of the person in whose name this Warrant has been issued, as well as the name and address of each transferee. The Partnership may treat the person in whose name any Warrant is registered on the register as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant.

(b) This Warrant and the rights granted hereunder shall be assignable by the Holder without the consent of the Partnership. Neither the Warrant nor the Warrant Units shall be transferable by any Holder except in compliance will all federal and applicable state securities laws. Prior to any transfer, and as a condition thereto, the Partnership’s general partner may require such documentation, including appropriate opinions of legal counsel, as it, in its sole discretion, deems necessary.

(c) The Partnership is obligated to register the Warrant Units for resale under the Securities Act pursuant to the Registration Rights Agreement, and the Holder (and assignees thereof) is entitled to the registration rights in respect of the Warrant Units as set forth in the Registration Rights Agreement.

Section 8. Adjustments. The Warrant Exercise Price and the number of Common Units issuable upon exercise of this Warrant shall be subject to adjustment from time to time as follows; provided, that if more than one subsection of this Section 8 is applicable to a single event, the subsection shall be applied that produces the largest adjustment and no single event shall cause an adjustment under more than one subsection of this Section 8 so as to result in duplication:

(a) Stock Splits, Subdivisions, Reclassifications or Combinations. If the Partnership shall (i) declare and pay a dividend or make a distribution on its Common Units in Common Units, (ii) subdivide or reclassify the outstanding Common Units into a greater number of units, or (iii) combine or reclassify the outstanding Common Units into a smaller number of units, the number of Warrant Units issuable upon exercise of this Warrant at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be proportionately adjusted so that a Warrant Holder after such date shall be entitled to purchase the number of Warrant Units which such Holder would have owned or been entitled to receive in respect of Common Units subject to this Warrant after such date had this Warrant been exercised immediately prior to such date. In such event, the Warrant Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be adjusted to the number obtained by dividing (x) the product of (1) the number of Warrant Units issuable upon the exercise of this Warrant before such adjustment and (2) the Warrant Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the dividend, distribution, subdivision, combination or reclassification giving rise to this adjustment by (y) the new number of Warrant Units issuable upon exercise of the Warrant determined pursuant to the immediately preceding sentence.

(b) Distributions. In case the Partnership shall fix a record date for the making of a distribution to all holders of Common Units of securities, evidences of indebtedness, assets, cash, rights or warrants (excluding Ordinary Cash Dividends, dividends of its Common Units and other dividends or distributions referred to in Section 8(a)), in each such case, the Warrant Exercise Price in effect prior to such record date shall be reduced immediately thereafter to the price determined by multiplying the Warrant Exercise Price in effect immediately prior to the reduction by the quotient of (x) the Weighted Average Price of the Common Units on the last trading day preceding the first date on which the Common Unit trades regular way on the Principal Market on which the Common Unit is listed or admitted to trading without the right to receive such distribution, minus the amount of cash and/or the fair market value of the securities, evidences of indebtedness, assets, rights or warrants to be so distributed in respect of one Common Unit as determined by the Board of Directors of the Partnership’s general partner in good faith (the “Fair Market Value”) divided by (y) such Weighted Average Price on such date specified in clause (x); such adjustment shall be made successively whenever such a record date is fixed. In such event, the number of Warrant Units issuable upon the exercise of this Warrant shall be increased to the number obtained by dividing (x) the product of (1) the number of Warrant Units issuable upon the exercise of this Warrant before such adjustment, and (2) the Warrant Exercise Price in effect immediately prior to the distribution giving rise to this adjustment by (y) the new Warrant Exercise Price determined in accordance with the immediately preceding sentence. In the case of adjustment for a cash dividend that is, or is coincident with, an Ordinary Cash Dividend, the Fair Market Value shall be reduced by the per unit amount of the portion of the cash dividend that would constitute an Ordinary Cash Dividend. In the event that such distribution is not so made, the Warrant Exercise Price and the number of Warrant Units issuable upon exercise of this Warrant then in effect shall be readjusted, effective as of the date when the Board of Directors of the Partnership’s general partner determines not to distribute such units, evidences of indebtedness, assets, rights, cash or warrants, as the case may be, to the Warrant Exercise Price that would then be in effect and the number of Warrant Units that would then be issuable upon exercise of this Warrant if such record date had not been fixed.

(c) Certain Repurchases of Common Units. In case the Partnership effects a Pro Rata Repurchase of Common Units, then the Warrant Exercise Price shall be reduced to the price determined by multiplying the Warrant Exercise Price in effect immediately prior to the Effective Date of such Pro Rata Repurchase by a fraction of which the numerator shall be (i) the product of (x) the number of Common Units outstanding immediately before such Pro Rata Repurchase and (y) the Weighted Average Price of a share of Common Units on the trading day immediately preceding the first public announcement by the Partnership or any of its Affiliates of the intent to effect such Pro Rata Repurchase, minus (ii) the aggregate purchase price of the Pro Rata Repurchase, and of which the denominator shall be the product of (i) the number of Common Units outstanding immediately prior to such Pro Rata Repurchase minus the number of Common Units so repurchased and (ii) the Weighted Average Price per Common Unit on the trading day immediately preceding the first public announcement by the Partnership or any of its Affiliates of the intent to effect such Pro Rata Repurchase. In such event, the number of Common Units issuable upon the exercise of this Warrant shall be increased to the number obtained by dividing (x) the product of (1) the number of Common Units issuable upon the exercise of this Warrant before such adjustment, and (2) the Warrant Exercise Price in effect

immediately prior to the Pro Rata Repurchase giving rise to this adjustment by (y) the new Warrant Exercise Price determined in accordance with the immediately preceding sentence. For the avoidance of doubt, no increase to the Warrant Exercise Price or decrease in the number of unit issuable upon exercise of this Warrant shall be made pursuant to this Section 13(c).

(d) Business Combinations. In case of any Business Combination or reclassification of Common Units (other than a reclassification of Common Units referred to in Section 8(a)), the Warrantholder’s right to receive Warrant Units upon exercise of this Warrant shall be converted into the right to exercise this Warrant to acquire the number of units or other securities or property (including cash) which the Common Unit issuable (at the time of such Business Combination or reclassification) upon exercise of this Warrant immediately prior to such Business Combination or reclassification would have been entitled to receive upon consummation of such Business Combination or reclassification; and in any such case, if necessary, the provisions set forth herein with respect to the rights and interests thereafter of the Holder shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to the Holder’s right to exercise this Warrant in exchange for any shares of stock or other securities or property pursuant to this paragraph. In determining the kind and amount of units, securities or the property receivable upon exercise of this Warrant following the consummation of such Business Combination, if the holders of Common Units have the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination, then the consideration that the Warrantholder shall be entitled to receive upon exercise shall be deemed to be the types and amounts of consideration received by the majority of all holders of the common stock that affirmatively make an election (or of all such holders if none make an election).

(e) Rounding of Calculations; Minimum Adjustments. All calculations under this Section 8 shall be made to the nearest one-tenth (1/10th) of a cent or to the nearest one hundredth (1/100th) of a share, as the case may be. Any provision of this Section 8 to the contrary notwithstanding, no adjustment in the Warrant Exercise Price or the number of Common Units into which this Warrant is exercisable shall be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a Common Unit, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or 1/10th of a Common Unit, or more.

(f) Timing of Issuance of Additional Common Units Upon Certain Adjustments. In any case in which the provisions of this Section 8 shall require that an adjustment shall become effective immediately after a record date for an event, the Partnership may defer until the occurrence of such event (i) issuing to the holder of this Warrant exercised after such record date and before the occurrence of such event the additional Common Units issuable upon such exercise by reason of the adjustment required by such event over and above the Common Units issuable upon such exercise before giving effect to such adjustment and (ii) paying to such holder any amount of cash in lieu of fractional Common Units; provided, however, that the Partnership upon request shall deliver to such holder a due bill or other appropriate instrument evidencing such holder’s right to receive such additional units, and such cash, upon the occurrence of the event requiring such adjustment.

(g) Statement Regarding Adjustments. Whenever the number of Warrant Units into which this Warrant is exercisable shall be adjusted as provided in this Section 8, the Partnership shall forthwith file at the principal office of the Partnership a statement showing in reasonable detail the facts requiring such adjustment and the number of Warrant Units into which Warrants shall be exercisable after such adjustment, and the Partnership shall also cause a copy of such statement to be sent by mail, first class postage prepaid, to the Holder at the address appearing in the Partnership’s records.

(h) Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustment pursuant to this Section 8, the Partnership shall take any action which may be necessary, including obtaining regulatory, or limited partner approvals or exemptions, in order that the Partnership may thereafter validly and legally issue as fully paid and nonassessable all Warrant Units issuable pursuant to the Warrants.

(i) Adjustment Rules. Any adjustments pursuant to this Section 8 shall be made successively whenever an event referred to herein shall occur.

Section 9. Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Partnership shall promptly, on receipt of an indemnification undertaking by the Holder (or in the case of a mutilated Warrant, the Warrant), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed.

Section 10. Notice. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Warrant must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (iii) one (1) Business Day after deposit with a nationally recognized overnight delivery service, in each case properly addressed to the party to receive the same. The addresses and facsimile numbers for such communications shall be:
