 Exhibit 10.6 

RESTRICTED UNIT AWARD AGREEMENT 
 This
RESTRICTED UNIT AWARD AGREEMENT (this “Agreement”) is made by and among Black Stone Minerals Company, L.P., a Delaware limited partnership (the
“Company”), Black Stone Natural Resources, L.L.C., a Delaware limited liability company and the general partner of the Company, and Thomas L. Carter, Jr. (the “Participant”) effective as of January 1, 2012 (the
“Grant Date”). 
 WHEREAS, the Company desires to grant to the Participant the Black Stone Units
specified herein, subject to the terms and conditions of this Agreement; and 
 WHEREAS, the Participant desires to
have the opportunity to hold such Black Stone Units, subject to the terms and conditions of this Agreement; 
 NOW,
THEREFORE, in consideration of the premises, mutual covenants and agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties
hereto, intending to be legally bound hereby, agree as follows: 
  

	1.	 Grant of Restricted Black Stone Units. Effective as of the Grant Date, the Company shall cause to be issued in the Participant’s
name 1,398,904 Black Stone Units as Restricted Units. The Company shall cause electronic book entries evidencing the Units and the Shares comprising such Restricted Units, and any additional Units or Shares or rights to acquire Units or
Shares distributed by the Company or the General Partner in respect of such Restricted Units during any Restricted Period (the “Retained Distributions”), to be issued in the Participant’s name. During the Restricted Period such
electronic book entries shall include a restrictive legend to the effect that ownership of the Units and the Shares comprising such Restricted Units (and any Retained Distributions), and the enjoyment of all rights appurtenant thereto, are subject
to the restrictions, terms, and conditions provided in this Agreement. The Participant shall have the right to vote the Restricted Units awarded to the Participant and to receive and retain all regular Distributions (other than Retained
Distributions), and to exercise all other rights, powers and privileges of a holder of Black Stone Units, with respect to such Restricted Units, with the exception that (a) the Company shall not remove the restrictive legend included in the
electronic book entries evidencing the Units and the Shares comprising such Restricted Units regarding the ownership of such Units and Shares until the Forfeiture Restrictions applicable thereto shall have expired, (b) the Company shall retain
custody of all Retained Distributions made or declared with respect to the Restricted Units (and such Retained Distributions shall be subject to the same restrictions, terms and conditions as are applicable to the Restricted Units) until such time,
if ever, as the Restricted Units with respect to which such Retained Distributions shall have been made, paid, or declared shall have become vested, and such Retained Distributions shall not bear interest or be segregated in separate accounts and
(c) the Participant may not sell, assign, transfer, pledge, exchange, encumber, or dispose of the Restricted Units or any Retained Distributions during the Restricted Period. The Participant hereby authorizes the Company to terminate, cancel
and revoke any electronic book entry evidencing the Units or the Shares comprising the Restricted Units and any 










	 	
securities constituting Retained Distributions which are forfeited pursuant to the terms of this Agreement and to transfer to the Company all of such Restricted Units and securities constituting
Retained Distributions. If during the Restricted Period the Company or the General Partner is not the surviving entity in any merger, consolidation, share or unit exchange or other reorganization or similar business transaction (or survives only as
a subsidiary of an entity other than an entity that was wholly-owned by the Company or the General Partner immediately prior to such merger, consolidation or other reorganization) then any consideration from such merger, consolidation, share or unit
exchange, reorganization or other business transaction that is attributable to the Restricted Units may be substituted by the Committee for the Units or the Shares comprising the Restricted Units as determined by the Committee and such consideration
shall be subject to the same restrictions, terms and conditions as were applicable to the Units or the Shares comprising the Restricted Units that are exchanged for such consideration until such time, if ever, as the Restricted Units with respect to
which such consideration shall have been received would have become vested. The Company may amend this Agreement as reasonably necessary, as determined by the Company, to reflect the substitution of any consideration from a merger, consolidation,
reorganization or other transaction for any Units or Shares comprising the Restricted Units. In accepting this Agreement and the award of Restricted Units set forth in this Agreement the Participant accepts and agrees to be bound by all the terms
and conditions of this Agreement.

transfer agent, if any, to stop registration of the transfer of the Units and the Shares comprising the Black Stone Units.

 - 4 - 









	 	(a)	General Vesting Rules. The Forfeiture Restrictions shall lapse as to the Restricted Units that are granted hereby in accordance with the following schedule provided that the Participant employment with the
Company and all of its Affiliates has not terminated prior to the applicable lapse date: 

  

	 	(i)	the Forfeiture Restrictions shall lapse as to one-third of the Restricted Units subject to this Agreement on the first anniversary of the Grant Date; 


 

	 	(ii)	the Forfeiture Restrictions shall lapse as to an additional one-third of the Restricted Units subject to this Agreement on the second anniversary of the Grant Date; and 


 

	 	(iii)	the Forfeiture Restrictions shall lapse as to the remaining one-third of the Restricted Units subject to this Agreement on the third anniversary of the Grant Date. 


If the Participant’s employment relationship with the Company and all of its Affiliates terminates before the applicable lapse date set
forth in this subsection (a), except as otherwise specified in subsection (b) below, the Forfeiture Restrictions then applicable to the Restricted Units shall not lapse and all the Restricted Units then subject to the Forfeiture
Restrictions shall be forfeited to the Company upon such termination of the Participant’s employment. 
 Upon the lapse of the
Forfeiture Restrictions with respect to a Black Stone Unit granted hereby the Company shall remove the restrictive legend included in the electronic book entry evidencing the Unit and the Share comprising such Black Stone Unit regarding the
ownership of the Unit and the Share and such Black Stone Unit shall be transferable by the Participant (except to the extent that any proposed transfer would, in the opinion of counsel satisfactory to the Company, constitute a violation of the
Limited Partnership Agreement of the Company, the Limited Liability Company Agreement of the General Partner, any other agreement regulating the transfer of Units or Shares, or any applicable securities law). 

Under procedures established by the Company from time to time, not later than 30 days prior to the applicable lapse date set forth above
in this subsection (a), the Participant may request that the Company purchase from the Participant on such lapse date up to 50 percent (50%) of the Restricted Units that vest on such lapse date, provided, however, that the Company has
no obligation to purchase any or all of such Restricted Units and the Company may deny the Participant’s request, in whole or in part, as determined in the sole discretion of the Company. 

 

	 	(b)	 Death, Disability or Termination Without Cause. Notwithstanding any provisions of Section 4(a) to the contrary, if the Participant’s
employment terminates due to the Participant’s death or Disability or if the Company terminates the Participant’s employment without Cause then on the date the Participant’s employment terminates due to his or her death or Disability
or the date the Company 



  
 - 5 - 









	 	
terminates the Participant’s employment without Cause the Forfeiture Restrictions shall lapse as to that number of the Restricted Units described in each of Section 4(a)(i),
(ii) and (iii) on the date the Participant’s employment terminates that have not previously vested pursuant to such provision equal to the product of (i) the quotient of (A) the number of days the Participant was employed
during the portion of the Restricted Period described in such provision divided by (B) the number of days in the portion of the Restricted Period described in such provision times (ii) the number of Restricted Units described in that
provision on the date the Participant’s employment terminates that have not previously vested pursuant to such provision, and the Participant shall forfeit to the Company all rights to all of the remaining Restricted Units awarded under this
Agreement. No determination made by the Committee under this Section 4 will have any effect on the finality of the termination of the Participant’s employment by the Company. The Committee, in the Committee’s sole and absolute
discretion, shall make all determinations required or necessary under this Section 4. In the event of conduct by the Participant which violates, or which the Committee believes may violate, the provisions of Section 4, the Company may
withhold any payments due the Participant pending a determination of the potential breach and forfeiture. The determination of whether the Participant’s conduct violates the provisions of Section 4 shall be made by the Committee after full
consideration of the facts presented both on behalf of the Company, any Affiliate and the Participant. Based on the Board’s knowledge of the manner in which the Participant now fulfills his or her responsibilities to the Company and performs
his or her duties, the Committee agrees that it is not now aware of any circumstance that would constitute Cause under this Agreement with respect to the Participant. The decision of the Committee, in the Committee’s discretion, as to all such
matters including the commission of the act and the damage done to the Company or an Affiliate shall be final and binding upon all interested parties. No decision of the Committee shall affect the finality of the discharge, if any, of the
Participant by the Company or an Affiliate in any manner. 

  

	5.	Tax Withholding. To the extent that the receipt of the Restricted Units or the lapse of any Forfeiture Restrictions results in income to the Participant for federal, state, local or foreign income,
employment or other tax purposes with respect to which the Company, the General Partner or any Affiliate has a withholding obligation, the Participant shall deliver to the Company at the time of such receipt or lapse, as the case may be, such amount
of money as the Company, the General Partner or any Affiliate may require to meet its obligation under applicable tax laws or regulations, and, if the Participant fails to do so, the Company, the General Partner or any Affiliate is authorized to
withhold from the Black Stone Units granted hereby or from any cash or other remuneration then or thereafter payable to the Participant in any capacity any tax required to be withheld by reason of such resulting income, sufficient to satisfy the
withholding obligation. 

  

	6.	No Fractional Units or Shares. All provisions of this Agreement concern whole Units and Shares. If the application of any provision hereunder would yield a fractional Unit or Share, such fractional
Unit or Share shall be rounded down to the next whole Unit or Share if it is less than 0.5 and rounded up to the next whole Unit or Share if it is 0.5 or more.

	7.	Capital Adjustments and Reorganizations. 

  

	 	(a)	The existence of the Restricted Units shall not affect in any way the right or power of the Company or the General Partner to make or authorize any adjustment, recapitalization, reorganization or other change in its
capital structure or its business, engage in any merger or consolidation, issue any debt or equity securities, dissolve or liquidate, or sell, lease, exchange or otherwise dispose of all or any part of its assets or business, or engage in any other
act or proceeding. 

  

	 	(b)	If the Company shall effect a subdivision or consolidation of the Units or other capital readjustment, the payment of a distribution in Units with respect to the Units, or other increase or reduction of the number of
Units outstanding, without receiving compensation therefore in money, services or property, then the number of Restricted Units awarded under this Agreement shall be appropriately adjusted by the Committee. 


 

	 	(c)	If the General Partner shall effect a subdivision or consolidation of the Shares or other capital readjustment, the payment of a distribution in Shares with respect to the Shares, or other increase or reduction of the
number of Shares outstanding, without receiving compensation therefore in money, services or property, then the number of Restricted Units awarded under this Agreement shall be appropriately adjusted by the Committee. 


 

	8.	Employment Relationship. For purposes of this Agreement, the Participant shall be considered to be in the employment of the Company or an Affiliate as long as the Participant has an employment
relationship with the Company or an Affiliate. The Committee shall determine any questions as to whether and when there has been a termination of such employment relationship, and the cause of such termination, under this Agreement and the
Committee’s determination shall be final and binding on all persons for purposes of this Agreement. 

  

	9.	Agreement Not an Employment Agreement. This Agreement is not an employment agreement or contract between the Company and the Participant that gives the Participant the right to be retained in the

Company or any of its Affiliates for any specified term, to interfere with the rights of the Company to discharge the Participant at any time, or to interfere with the Participant’s right to terminate his or her employment at any time.

thereunder.

written instrument executed and delivered by the party waiving compliance hereof shall waive any of the terms or conditions of this Agreement. Any waiver granted by the Company shall be effective only if executed and delivered by a duly authorized
executive officer of the Company other than the Participant. The failure of any party at any time or times to require performance of any provisions hereof shall in no manner affect the right to enforce the same. No waiver by any party of any term or
condition, or the breach of any term or condition contained in this Agreement, in one or more instances, shall be construed as a continuing waiver of any such condition or breach, a waiver of any other condition, or the breach of any other term or
condition. If the Company changes its transfer procedures regarding Units or Shares the Participant agrees that the Company may amend this Agreement as reasonably necessary, as determined by the Company, to reflect such changes.
