This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and permitted assigns. Neither the Sellers nor the Purchaser shall assign this Agreement or any of their respective rights or obligations hereunder without the prior written consent of the other Party.

6.7 No Third Party Beneficiaries.

This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and permitted assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other person.

6.8 Survival.

Unless this Agreement is terminated by mutual consent of the Sellers and the Purchaser, the representations and warranties of the Sellers and the Purchaser contained in Articles II and III shall survive the Closing Dates and the delivery, in whole or in part, of the Purchased Units.

6.9 Termination.

Notwithstanding anything to the contrary in this Agreement, this Agreement may be terminated and the transactions contemplated hereby may be abandoned at any time prior to the Second Closing Date:

(a) by the mutual written agreement of Seller and Purchaser;

(b) by Purchaser if the First Closing has not occurred on or prior to the fifth (5^th) day after the date hereof (the “First Termination Date”) or the Second Closing has not occurred on or prior to the sixtieth (60^th) day after the First Closing Date (the “Second Termination Date”, and with the First Termination Date, each a “Termination Date”); provided that Purchaser is not at such time in breach in any material respect of any of its representations or obligations hereunder;

(c) by Seller if the First Closing has not occurred on or prior to the First Termination Date or the Second Closing has not occurred on or prior to the Second Termination Date, provided that Seller is not at such time in breach in any material respect of any of its representations or obligations hereunder;

(d) by either Party if there has been a breach by the other Party of any representation, warranty, covenant or agreement set forth in this Agreement and the effect of such breach would be to cause the conditions to the terminating Party’s obligations to consummate the Closing not to be capable of being satisfied, and such breach is not cured or is not reasonably capable of being cured within 10 days of receiving written notice of such breach or alleged breach from the terminating Party, it being understood and agreed that this Agreement may not be terminated pursuant to this Section 6.9(d) during such 10-day period or following such10-day period if such breach is cured during such 10-day period (provided, however, that such 10-day period shall not extend the applicable Termination Date); or

(e) by either Party if there shall be in effect a final, non-appealable law, rule, regulation, order, judgment or decree (including federal and state securities laws) (“Order”) of a federal, state, local or foreign government, governmental authority, regulatory or administrative agency, governmental department, board, bureau, agency or instrumentality, or court or tribunal of competent jurisdiction restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated hereby; it being agreed that the Parties shall promptly appeal any adverse determination which is appealable (and pursue such appeal with reasonable diligence); provided, however, that the right to terminate this Agreement under this Section 6.9(e) shall not be available to a Party if such Order was primarily due to the failure of such Party to perform any of its obligations under this Agreement.

If this Agreement is terminated and the transactions contemplated hereby are abandoned in accordance with this Section 6.9, this Agreement shall become void and of no further force and effect (other than this Section 6.9, Section 6.8 and Sections 6.11, 6.12, and 6.13 each of which shall survive the termination of this Agreement and be enforceable by the Parties and, for the avoidance of doubt, with respect to the transfer of any Purchased Units pursuant to a Closing that has already occurred, which transfer shall remain in full force and effect), and there shall be no liability or obligation on the part of any Party to the other Party, except for material breaches of this Agreement prior to the time of such termination and pursuant to Sections 6.11 and 6.12. Nothing in this Section 6.9 shall be deemed to impair the right of either Party to compel specific performance by the other Party of its obligations under this Agreement.

6.10 Release of Escrow Amount.

If the Second Closing has not occurred by the Termination Date, on the first business day following the termination of this Agreement, Purchaser and each Seller will jointly instruct the Escrow Agent under the Escrow Agreement to release to the Purchaser the Escrow Amount. The Escrow Agreement shall provide for the payment to the Sellers of any interest on the Escrow Amount. For the avoidance of doubt, upon the release of the Escrow Amount to the Purchaser, the Sellers shall be under no obligation to sell the Second Closing Units hereunder.

6.11 Indemnification Obligations of Seller.

Each Seller shall jointly and severally defend, indemnify and hold harmless Purchaser and its affiliates (including the Company) and their respective officers, directors, shareholders, successors and permitted assigns (all such Persons are collectively referred to herein as the “Purchaser Indemnitees”) against and from all liabilities, demands, claims, regulatory, legislative or judicial proceedings or investigations, assessments, taxes, levies, losses, fines, penalties, damages, costs, interest, deficiencies and expenses, including, without limitation, reasonable attorneys’, accountants’, investigators’, and experts’ fees and expenses, sustained or incurred in connection with the defense, investigation, adjudication, settlement or other resolution of any claim (“Damages”) sustained or incurred by any of the Purchaser Indemnitees resulting from or arising out of or by virtue of: (a) any inaccuracy in or breach of any representation and warranty made by such Seller in this Agreement; and (b) any breach by such Seller or failure by such Seller to comply with any of the covenants or obligations of such Seller under this Agreement.

6.12 Indemnification Obligations of Purchaser.

Purchaser shall defend, indemnify, save and keep harmless each Seller and its affiliates (including the Company) and their respective officers, directors, shareholders, successors and permitted assigns (all such Persons are collectively referred to herein as the “Seller Indemnitees”) against and from all Damages sustained or incurred by any of them resulting from or arising out of or by virtue of: (a) any inaccuracy in or breach of any representation and warranty made by Purchaser in this Agreement; (b) any breach by Purchaser of, or failure by Purchaser to comply with, any of its covenants or obligations under this Agreement; and (c) any actions or omission taken by the Purchaser after the First Closing not in the control of the Sellers, including, without limitation, related to the issuance of additional units of the Company or Rhino GP or to indebtedness of the Company that is not repaid at or prior to the Second Closing (including, without limitation resulting from any default under the Credit Agreement resulting from consummation of the transactions contemplated by this Agreement).

6.13 No Strict Construction.

The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

In the event that any signature is delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of an executed signature page, such signature page shall create a valid and binding obligation of the Party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.

6.15 Confidentiality.

The Purchaser and the Sellers each hereby agrees, without the prior written consent of the other, to not disclose, and to otherwise keep confidential, the sale of the Purchased Units contemplated hereby, except to the extent that disclosure thereof is required by law, rule or regulation or as required or requested by any competent governmental, regulatory or supervisory authority or has become publicly known through no fault of such Party; provided, however, that the Purchaser and the Sellers may disclose information regarding such sale to their respective accountants, attorneys, limited partners, shareholders and other interest holders; provided, further, however, that the Parties acknowledge that the Company will be required to file a current report on Form 8-K disclosing this Agreement and the Sellers and Purchaser and other parties may be required to make filings pursuant to Section 13 and 16 of the Exchange Act.

No provision in this Lock-Up Letter Agreement shall be deemed to restrict or prohibit (1) the exercise, exchange or conversion by the undersigned of any securities exercisable or exchangeable for or convertible into Common Units or Subordinate Units, as applicable; provided that any Common Units or Subordinate Units received upon exercise of options granted to the undersigned will also be subject to this Lock-Up Letter Agreement, (2) transfers of Common Units or Subordinate Units or securities convertible into or exercisable or exchangeable for Common Units or Subordinate Units as a bona fide gift, by will or intestacy or to a family member or trust for the benefit of a family member (for purposes of this lock-up agreement, “family member” means any relationship by blood, marriage or adoption, not more remote than first cousin), (3) to an entity wholly owned, directly or indirectly, by the undersigned and/or family members of the undersigned or for their benefit, (4) transfers of Common Units or Subordinate Units or securities convertible into or exercisable or exchangeable for Common Units or Subordinate Units to a charity or educational institution or (5) transactions in Common Units or Subordinate Units or securities convertible into or exercisable or exchangeable for Common Units or Subordinate Units for the purpose of paying taxes due in connection with any grant or vesting of securities of the Company; provided, that in the case of any transfer pursuant to the foregoing clauses (2), (3) or (4), any such transfer shall not involve a disposition for value.
