the foregoing, if the Company waives the restrictions on Transfer applicable to Daniel Och or the Existing Partners pursuant to the Operating Group Limited Partnership Agreements, and such waiver permits the Transfer or sale, on a cumulative basis, of (i) at least 10% of the Class A Shares owned by Daniel Och as of the closing of the Initial Offering or (ii) at least 10% of the Class A Shares owned by Daniel Och and the other Existing Partners in the aggregate as of the closing of the Initial Offering (in all cases, calculated as if all of the then issued and outstanding Och-Ziff Operating Group A Units had been exchanged for Class A Shares pursuant to the terms of the Exchange Agreement but disregarding any Class A restricted share units), Investor will be granted a pro rata waiver of the restrictions on Transfer set forth in this Section 6.1(a) with respect to the Purchased Class A Shares (based on the ratio of the number of Purchased Class A Shares held by Investor on the Closing Date to the number of Class A Shares held by the Existing Partners on the Closing Date (calculated as if all of the then issued and outstanding Och-Ziff Operating Group A units had been exchanged for Class A Shares pursuant to the terms of the Exchange Agreement, but disregarding any Class A restricted share units)). The waiver provided for in the preceding sentence will only be effective to the extent it would cause there to be an increase in the percentage of Purchased Class A Shares as to which the restrictions on Transfer have lapsed, pursuant to Section 6.1(b).

(b) On each of the second, third, fourth and fifth anniversaries of the Closing Date of the Initial Offering, the restrictions on Transfer set forth in Section 6.1(a) will terminate as to a number of the Purchased Class A Shares equal to 25% of the Purchased Class A Shares held by Investor on the Closing Date. Notwithstanding the foregoing, the restrictions on Transfer set forth in Section 6.1(a) will terminate in their entirety upon the occurrence of a payment of at least $100 million by the Company to Investor or its Permitted Transferees constituting indemnification under the terms of this Agreement.

(c) The restrictions on Transfer set forth in this Section 6.1 shall be waivable at any time by the Chief Executive Officer of the Company.

(d) Notwithstanding the restrictions set forth in this Section 6.1, Guarantor shall have the right to pledge the shares of Investor and Investor shall have the right to pledge its Purchased Class A Shares as security for a bridge loan pursuant to which the Guarantor shall be the obligor or shall provide a full and unconditional guarantee with a term not to exceed six (6) months, it being understood that upon foreclosure, the maker or makers of such loan shall not succeed to the rights of Investor referred to under Section 6.2, Section 8.4, Section 8.5, Section 8.7 and Section 8.11. Such maker or makers shall be subject to the restrictions on Transfer set forth in Section 6.1(a) and the drag-along rights set forth in Section 6.3.

Section 6.2 Tag-Along Rights

(a) Notwithstanding anything to the contrary in this Agreement, in connection with the Transfer (other than a pledge, hypothecation, mortgage or encumbrance), in one or a series of related transactions, by the Existing Partners to a single Person or group of Persons (other than to Permitted Transferees) of Company Securities representing in the

7

aggregate at least 9.9% of the outstanding Class A Shares of the Company (calculated on a fully-diluted basis and as if all then issued and outstanding Och-Ziff Operating Group A Units had been exchanged for Class A Shares pursuant to the terms of the Exchange Agreement) at any time prior to the end of the Restriction Period in a transaction exempt from registration under the Securities Act and any similar applicable state securities laws (a “Tag-Along Sale”), prior to the consummation thereof, Investor shall be afforded the opportunity to join in such Transfer on a pro rata basis, as provided in Section 6.2(b) below. For the avoidance of doubt, sales by the Existing Partners pursuant to the provisions of Rule 144 shall not be subject to the provisions of this Section 6.2.

(b) Prior to consummation of the Tag-Along Sale, the Existing Partners proposing to Transfer Company Securities in the Tag-Along Sale (the “Tag-Along Sellers”) shall cause the Person or group of Persons that proposes to acquire such Company Securities (the “Proposed Purchaser”) to offer in writing (the “Tag-Along Offer”) to purchase Class A Shares owned by Investor, such that the number of Class A Shares so offered to be purchased from Investor shall be equal to the product obtained by multiplying the aggregate number of Company Securities proposed to be purchased by the Proposed Purchaser (calculated on a fully-diluted basis and as if all then issued and outstanding Och-Ziff Operating Group A Units had been exchanged for Class A Shares) by such Investor’s Pro Rata Portion. In addition, the Tag-Along Offer shall set forth the consideration for which the Tag-Along Sale is proposed to be made and all other material terms and conditions of the Tag-Along Sale. If the Tag-Along Offer is accepted by Investor within five Business Days after receipt of the Tag-Along Offer, then the number of Company Securities to be sold to the Proposed Purchaser by the Tag-Along Sellers (calculated on a fully-diluted basis and as if all then issued and outstanding Och-Ziff Operating Group A Units had been exchanged for Class A Shares) shall be reduced by the number of Class A Shares to be purchased by the Proposed Purchaser from Investor. The purchase from Investor shall be made on the same terms and conditions (including timing of receipt of consideration and choice of consideration, if any) as the Proposed Purchaser shall have offered to purchase Company Securities to be sold by the Tag-Along Sellers, and the Investor shall otherwise be required to Transfer the Class A Shares upon the same terms, conditions, and provisions as the Tag-Along Sellers, including making the same representations, warranties, covenants, indemnities and agreements that the Tag-Along Sellers agree to make. “Pro Rata Portion” shall mean for purposes of this Section 6.2, with reference to the Investor, a fraction, the numerator of which is the number of Class A Shares then held by Investor, and the denominator of which is the number of issued and outstanding Company Securities calculated on a fully-diluted basis and as if all then issued and outstanding Och-Ziff Operating Group A Units had been exchanged for Class A Shares.

Section 6.3 Drag-Along Rights.

(a) If at any time prior to expiration of this Agreement, if any Existing Partner or a group of Existing Partners is proposing to dispose of or sell (other than to Permitted Transferees) Company Securities representing in the aggregate at least 50% of the Class A Shares of the Company then outstanding (calculated on a fully-diluted basis and as if all then issued and outstanding Och-Ziff Operating Group A Units had been exchanged pursuant to the

8

terms of the Exchange Agreement for Class A Shares) pursuant to a bona fide offer from a third party (a “Drag-Along Sale”), such Existing Partner(s) may, at its/their option, require the Investor, each other Permitted Transferee of the Investor that holds any of the Purchased Class A Shares, to sell that number of Class A Shares as determined in accordance with Section 6.3(d) below to the purchaser in the Drag-Along Sale (the “Purchaser”) by giving written notice (the “Notice”) to the Investor not later than ten (10) Business Days prior to the consummation of the sale contemplated by the Drag-Along Sale (the “Drag-Along Right”); provided, however, that if the Existing Partners exercise the Drag Along Right, the Existing Partners shall cause all Existing Partners holding Class A Shares (or equity exchangeable for Class A Shares) to sell that number of shares as determined in accordance with Section 6.3(d) to such Purchaser on the same terms and conditions. The Notice shall contain written notice of the exercise of such Existing Partners’ rights pursuant to Section 6.3 of this Agreement, setting forth the consideration per share to be paid by the Purchaser and the other material terms and conditions of the Drag-Along Sale.

(b) The purchase of Class A Shares by a Purchaser from the Investor (or its Permitted Transferees) pursuant to this Section 6.3 shall be on the same terms and conditions, including the per share price and the date of sale, as applicable to the Existing Partners and stated in the Notice provided to the Investor pursuant to Section 6.3(a) above.

(c) Within five (5) Business Days following the date of the Notice, the Investor (or its Permitted Transferees) shall deliver to the Existing Partners such Class A Shares owned by the Investor (or its Permitted Transferees) and determined in accordance with Section 6.3(d) below and a limited power-of-attorney authorizing such Existing Partners to sell such shares pursuant to the terms of the Drag-Along Sale and such other transfer instruments and other documents as are reasonably requested by the Existing Partners in order to effect such sale.

(d) If the Existing Partners exercise their rights pursuant to Section 6.3(a) with respect to the Class A Shares, the Investor (or its Permitted Transferees) and each Existing Partner shall sell that number of Class A Shares equal to the product of (A) the total number of Class A Shares to be acquired pursuant to the Drag-Along Sale, times (B) a fraction, the numerator of which shall be the total number of Class A Shares then held by the Investor (or its Permitted Transferees) in the case of Investor, or the total number of Class A Shares and Och-Ziff Operating Group A Units then held by the Existing Partners in the case of an Existing Partner, and the denominator of which shall be the sum of (i) the total number of Class A Shares and Och-Ziff Operating Group A Units then collectively owned by the Existing Partners and (ii) the total number of Class A Shares then owned by the Investor (and its Permitted Transferees).

Section 6.4 Legend. Each certificate representing Purchased Class A Shares shall contain the following legend:

“THE SHARES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO THE PROVISIONS OF THE SECOND AMENDED AND RESTATED LIMITED LIABILITY COMPANY AGREEMENT OF THE COMPANY (THE “LLC AGREEMENT”) AND A SECURITIES PURCHASE AND

Re: Och-Ziff Capital Management Group, LLC – Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with Och-Ziff Capital Management Group, LLC, a Delaware limited liability company (the “Company”), providing for a public offering of Class A shares representing Class A limited liability interests of the Company (the “Shares”) pursuant to a Registration Statement on Form S-1 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer, dispose of or hedge, directly or indirectly, or enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of any Shares (including, without limitation, Shares that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the SEC and securities that may be issued upon exercise of a share option or warrant), or any securities convertible into or exercisable or exchangeable for Shares, whether any such transaction is to be settled by delivery of Shares or other such securities, in cash or otherwise (collectively the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Shares.

B-1

The initial Lock-Up Period will commence on the date of this Lock-Up Agreement and continue for 180 days after the public offering date set forth on the final prospectus used to sell the Shares (the “Public Offering Date”) pursuant to the Underwriting Agreement; provided, however, that if (1) during the last 17 days of the initial Lock-Up Period, the Company releases earnings results or announces material news or a material event or (2) prior to the expiration of the initial Lock-Up Period, the Company announces that it will release earnings results during the 15-day period following the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be automatically extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the announcement of the material news or material event, as applicable, unless the Representatives waive, in writing, such extension.

The undersigned hereby acknowledges that the Company has agreed in the Underwriting Agreement to provide written notice of any event that would result in an extension of the Lock-Up Period pursuant to the previous paragraph to the undersigned (in accordance with Section 13 of the Underwriting Agreement) and agrees that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the initial Lock-Up Period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as such may have been extended pursuant to the previous paragraph) has expired.

Notwithstanding the foregoing, (a) the undersigned may pledge the Undersigned’s Shares as security for the bride loan referred to in Section 6.1(d) in the Securities Purchase and Investment Agreement dated [ ] (the “Purchase Agreement”) and (b) the undersigned may transfer the Undersigned’s Shares to any Permitted Transferee as defined in the Purchase Agreement. The undersigned now has, and for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever except as set forth in the Purchase Agreement. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Undersigned’s Shares except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.
