(a) Anything in the Subordinated Agreements to the contrary notwithstanding, each Investor hereby subordinates and defers the payment of the Subordinated Obligations, and the Subordinated Obligations are and shall be hereby made expressly subordinate and junior in right of payment to the prior indefeasible payment in full in cash of the Senior Indebtedness and termination of the Senior Credit Agreement and the Indenture, and the Subordinated Obligations are hereby subordinated as a claim against the Companies and the Management Stockholders (relating to the Senior Indebtedness) or any of the assets of, or ownership interests in, the Companies whether such claim be (i) in the event of any distribution of the assets of a Company upon any voluntary or involuntary dissolution, winding-up, total or partial liquidation or reorganization, or bankruptcy, insolvency, receivership or other statutory or common law 4 proceedings or arrangements involving a Company or the readjustment of the liabilities of a Company or any assignment for the benefit of creditors or any marshaling of the assets or liabilities of a Company (any of the foregoing being hereinafter referred to as a "Reorganization"), (ii) in connection with a sale of the Companies pursuant to the Subordinated Agreements or otherwise or (iii) other than in connection with any Reorganization or any such sale, to the prior indefeasible payment in full in cash of the Senior Indebtedness and termination of the Senior Credit Agreement and the Indenture. In furtherance of the foregoing, except as provided in Section 3.6 hereof, the Companies will not make, and no holder of Subordinated Obligations will accept or receive, any payment of Subordinated Obligations until all the Senior Indebtedness has been indefeasibly paid and satisfied in full in cash and the Senior Credit Agreement and the Indenture have been terminated. (b) Further, so long as any Claim (as defined in Section 5 hereof) of Agent or any of the Senior Lenders or the Trustee or any Senior Subordinated Noteholder against any of the Companies, the Management Stockholders (relating to the Senior Indebtedness) or any portion of the Senior Indebtedness remains outstanding or unsatisfied, and until the Senior Credit Agreement and the Indenture have been terminated, each Investor agrees that it shall not (i) exercise any of its rights under the Warrants or any other option, warrant, call or other Right (other than, subject to Section 8 hereof, the Investors' rights under Articles VI and VIII of the Warrant Agreement and under any irrevocable proxy granted to effectuate the Investors' rights under Articles VI and VIII of the Warrant Agreement) it may now have or hereafter acquire with respect to any portion of the capital stock of any of the Companies (collectively, "Equity Rights"), whether acquired pursuant to the Subordinated Agreements or otherwise (A) unless after the exercise of such Warrants or other Equity Rights, the Investors will not own, directly or indirectly, 65% or more of Radio One or any other Company nor be entitled to elect or designate for election a majority of the Board of Directors of any Company, (B) if as a result of such exercise of the Warrants or other Equity Rights, Hughes and Liggins shall not continue to directly own of record and beneficially and to control 35% or more of Radio One and the Companies or would not be entitled to elect or designate for election a majority of the Board of Directors of any Company and (C) so long as any capital stock to be issued in connection with the exercise of its Warrant is required to be pledged to the Agent for the benefit of the Senior Lenders, unless such Investor shall have first (x) notified the Senior Lenders and the Trustee of its desire to exercise its Warrant, (y) instructed and notified Radio One that any capital stock to be issued in connection with the exercise of any Warrant of any Investor shall be delivered directly to Agent as security for the Primary Senior Indebtedness and (z) such Investor shall simultaneously pledge such capital stock to the Agent for the benefit of the Senior Lenders pursuant to a pledge agreement in form and substance satisfactory to the Senior Lenders and deliver to Agent stock powers (executed in blank) covering such capital stock, (ii) exercise any rights it now has or hereafter acquires to require a Company to repurchase any of the Warrants pursuant to the Subordinated Agreements or otherwise, or (iii) accept any sums in consideration of repurchase of any of the Warrants. 5 3.3 Distributions in Reorganization. (a) In the event of any Reorganization relative to a Company or property of a Company, all of the Senior Indebtedness shall first have been indefeasibly paid in full in cash and the Senior Credit Agreement and the Indenture shall have been terminated before any payment whatsoever is made upon or in respect of the Subordinated Obligations (including but not limited to payments on account of redemption, liquidation, dividends, or principal, premium, interest or otherwise), and in any such proceedings any payment or distribution of any kind or character whatsoever, whether in cash or property or securities which may be payable or deliverable in respect of the Subordinated Obligations shall be paid or delivered directly to the (i) Agent for the benefit of the Senior Lenders for application in payment of the Primary Senior Indebtedness, unless and until the Investors shall have received notice in writing from the Agent that all such Primary Senior Indebtedness shall have been indefeasibly paid and satisfied in full in cash and the Senior Credit Agreement shall have been terminated, and (ii) thereafter to the Trustee, for the benefit of the Senior Subordinated Noteholders, for application in payment of the Senior Subordinated Notes and all monetary obligations of any Company under the Indenture, unless and until the Investors shall have received notice in writing from the Trustee that all such Senior Subordinated Notes and all monetary obligations under the Indenture of any Company shall have been indefeasibly paid and satisfied in full in cash and the Indenture shall have been terminated. In the event that, notwithstanding the foregoing, upon any such Reorganization, any payment or distribution of assets of a Company of any kind or character whatsoever, whether in cash, property or securities, shall be received by any holder of the Subordinated Obligations before all of the Senior Indebtedness is indefeasibly paid in full in cash and the Senior Credit Agreement and the Indenture have been terminated, the Investors agree hereby to cause all such payments and distributions to be immediately paid over, first, to the Agent for the benefit of the Senior Lenders, for application to the payment of all Primary Senior Indebtedness remaining unpaid until the Investors shall have received notice in writing from the Agent that all such Primary Senior Indebtedness shall have been indefeasibly paid in full in cash and the Senior Credit Agreement has been terminated, and second, to the Trustee for the benefit of the Senior Subordinated Noteholders, for application to the payment of all Senior Subordinated Notes and all other monetary obligations of any Company under the Indenture, until the Investors shall have received notice in writing from the Trustee that all such Senior Subordinated Notes and such other monetary obligations shall have been indefeasibly paid in full in cash and the Indenture has been terminated. (b) Until such time as the Senior Indebtedness has been indefeasibly paid and satisfied in full in cash and the Senior Credit Agreement and the Indenture shall have been terminated, each of the Investors irrevocably authorizes and empowers the Agent, on behalf of the Senior Lenders, and at such time as the Primary Senior Indebtedness shall have been indefeasibly paid in full, the Trustee, on behalf of the Senior Subordinated Noteholders, in any proceedings under any Reorganization (i) to file a proof of claim on behalf of any or all of the Investors with respect to the Subordinated Obligations if any such Investor fails to file proof of its claims prior to 30 days before the expiration of the time period during which such claims must be submitted, (ii) to accept and receive any payment or distribution which may be payable or deliverable at any time upon or in respect of such Subordinated Obligations, provided that at such time as the Primary Senior Indebtedness shall have been indefeasibly paid in full, amounts received thereafter by the Agent, if any, shall be delivered by the Agent to the Trustee for the benefit of the Senior Subordinated 6 Noteholders, (iii) to prove any and all claims, or seek enforcement thereof, of each of the Investors in any Reorganization proceeding and (iv) to take such other action as may be reasonably necessary to effectuate any of the foregoing. Upon the Agent's or the Trustee's reasonable request, each Investor agrees severally and not jointly to provide to the Agent and the Trustee, all information and documents necessary to present claims or prove claims or seek enforcement thereof as aforesaid. The Investors shall retain the exclusive right to vote their claims in any Reorganization; provided, that no Investor shall be entitled to take any action or vote in any way and each such Investor hereby agrees severally and not jointly to not take any action or vote in any way, so as to contest (i) the validity or the enforceability of the Senior Credit Agreement, any of the other Loan Documents or any of the liens or security interests which secure the payment or performance of the Primary Senior Indebtedness, (ii) the validity or the enforceability of the Indenture, the Senior Subordinated Notes, the Subordinated Guaranties or any other document executed in connection therewith, or (iii) the validity or enforceability of this Agreement or any agreement or instrument to the extent evidencing or relating to the Senior Indebtedness. Neither the Agent and the Senior Lenders, nor the Trustee and the Senior Subordinated Noteholders, shall in any event be liable for any failure to prove the Subordinated Obligations; for failure to exercise any rights with respect thereto; or for failure to collect any sums payable thereon or for failure to take any affirmative action in connection therewith. 3.4 Effect of Provisions. The provisions hereof as to subordination are solely for the purpose of defining the relative rights of the holders of Senior Indebtedness on the one hand, and the holders of the Subordinated Obligations on the other hand, and, except as otherwise expressly provided herein, none of such provisions shall impair, as between the Companies and the holders of the Subordinated Obligations, the obligations of the Companies, which are unconditional and absolute to pay to such holders all of the Subordinated Obligations in accordance with the terms thereof. 3.5 Subrogation, etc. The holders of the Subordinated Obligations shall not be subrogated to the rights of the holders of the Senior Indebtedness in respect of payments or distributions of assets of, or ownership interests in, the Companies made on the Senior Indebtedness, if at all under applicable law, until the Senior Indebtedness shall have been indefeasibly paid in full in cash and the Senior Credit Agreement and the Indenture have been terminated. 3.6 Permitted Payments of Subordinated Obligations. Radio One may, from time to time, pay or cause to be paid to any holder of Subordinated Obligations, and any such holder may accept and retain, payments or other distributions, including without limitation in respect of any redemption or other payment in respect of the Preferred Stock, to the extent, and solely to the extent, permitted (i) under the Senior Credit Agreement, so long as any Primary Senior Indebtedness thereunder remains unpaid and the Senior Credit Agreement has not been terminated, and (ii) under the Indenture, so long as the Senior Subordinated Notes, and all monetary obligations in connection therewith, remain unpaid, and the Indenture has not been terminated. 4.

If any holder of Subordinated Obligations shall receive any payment with respect to the Subordinated Obligations in any form and from any source 7 whatsoever (including, without limitation, any payment or distribution of collateral security, if any, or the proceeds of any collateral security) in violation of this Agreement, it shall hold such payment in trust first, for the benefit of the Senior Lenders and, promptly upon discovery or notice of such violation, pay it over to Agent for the benefit of the Senior Lenders for application to payment of the Primary Senior Indebtedness; and upon receipt of notice from the Agent that the Primary Senior Indebtedness has been paid in full and the Senior Credit Agreement has been terminated, shall thereafter, pay it over to the Trustee for the benefit of the Senior Subordinated Noteholders for application in payment of the Senior Subordinated Notes and other monetary obligations under the Indenture. 5.

As used herein, the term "Claims" shall mean the Senior Indebtedness and any and all now existing and future indebtedness, obligations or liabilities, including without limitation any post petition interest, of the Companies to Agent and the Senior Lenders, or the Trustee and the Senior Subordinated Noteholders, whether direct or indirect, absolute or contingent, secured or unsecured, arising under the Senior Credit Agreement, the Notes, or any other Loan Documents, or the Indenture or the Senior Subordinated Notes, or the Subordinated Guaranties, as now written or as amended, modified, restated, supplemented, renewed, extended, increased, rearranged or substituted hereafter or by operation of law or otherwise, including any and all expenses (including reasonable attorneys' fees) incurred in connection therewith and any interest thereon.

Requirement of Notice. (a) The Investors agree to notify Agent and the Senior Lenders and the Trustee, on behalf of the Senior Subordinated Noteholders immediately upon the happening of any of the following: (i) the Investors declare an event of default, elect to exercise rights of any mandatory redemption or put in respect of the Preferred Stock, or elect to exercise any rights to convert the Preferred Stock or Warrants into common stock or indebtedness of the Company or any Subsidiary, under any of the Subordinated Agreements; (ii) the waiver by the Investors of any material default or redemption event under any of the Subordinated Agreements; (iii) the acceleration or occurrence of any event requiring redemption of the Subordinated Obligations, or event which provides increased voting rights to the Investors, or creates a Change of Control (as defined in the Senior Credit Agreement or the Indenture); (iv) actual knowledge of the occurrence of a breach by the Company or any Subsidiary of any event under Section 10 of the Preferred Stockholders Agreement or under the Warrant Agreement which permits the Investors to require the Company to seek a sale of the Company or its assets, or a refinancing of its indebtedness and obligations in respect of the Preferred Stock, in each case, subject to the terms hereof; or (v) actual knowledge of any breach by an Investor under this Agreement, or any Loan Document to which an Investor is a party executed in connection with the Senior Credit Agreement, or the Indenture.

In the event of any inconsistency between the terms of this instrument/agreement and the terms of such Standstill Agreement, the terms of the Standstill Agreement shall govern and be controlling." 8. Limit on Right of Action. Each Investor, for itself and its successors and assigns, agrees for the benefit of the holders of the Senior Indebtedness that until indefeasible payment in full in cash of the Senior Indebtedness and termination of the Senior Credit Agreement and the Indenture, such Investor will not take any action to accelerate or demand payment by a Company of the Subordinated Obligations, or exercise a right of redemption or a put (to the Company) in respect of the Subordinated Obligations, or exercise any of its remedies in respect of the Subordinated Obligations, to initiate any Reorganization of, or litigation against, a Company, or to foreclose or otherwise realize on any Lien, if any, given by a Company or any other Person to secure the Subordinated Obligations; provided, however, that the Investors may accelerate or exercise a right of redemption of the Subordinated Obligations upon the earlier to occur of (i) a Reorganization of the Company (provided that the Investors agree to rescind any acceleration or notice of mandatory redemption resulting from a Reorganization which is an involuntary proceeding dismissed or discharged within 60 days thereof), (ii) the acceleration of the Primary Senior Indebtedness by the holders thereof, (iii) the date which is 180 days after the date the Investors notify the Agent that one of the events under subsections (a), (b) or (c) of Section 10 of the Preferred Stockholders Agreement has occurred so long as such event is continuing at the time of acceleration or exercise of the right of redemption or a put (to the Company); provided further, however, after prior written notice to Agent, the Investors may also initiate litigation against the Companies and the Management Stockholders after either one of the events set forth in the foregoing subsections (i) or (ii) have occurred. Notwithstanding the foregoing, the Investors may (x) sue for specific performance of any of the covenants in the Subordinated Agreements pursuant to their Rights thereunder so long as such action is not in conflict with this Agreement, does not involve an acceleration or an exercise of the right of mandatory redemption or a put (to the Company) of the Subordinated Obligations, the creation of any liens, the payment of, or determination of, any obligation for money damages or the payment of any sums whatsoever to the Investors, and (y) take the actions contemplated by Section 10 of the Preferred Stockholders Agreement and Article VI or Article VIII of the Warrant Agreement pursuant to their rights thereunder as in effect on the date hereof; provided, however, that at such time as the Agent and/or the Senior Lenders have commenced to actively pursue the exercise of their Rights under the Loan Documents to conduct a sale of the Collateral securing the Primary Senior Indebtedness, either pursuant to the exercise of foreclosure Rights, an agreed-upon-sale, or deed-in-lieu of foreclosure, or otherwise, or the Trustee on behalf of the Senior Subordinated Noteholders has commenced to actively pursue the exercise of their Rights under the Senior Subordinated Notes or the Indenture, then the Investors shall no 10 longer have the right to take any of the actions permitted to be taken by the Investors hereunder (other than acceleration or exercise of a right to require the Company to redeem any or all shares of Preferred Stock under Section 8.1 of the Preferred Stockholders Agreement, as applicable, the actions permitted under Section 3.3 hereof, or actions to perfect the Investors' rights to payment from any excess proceeds arising from the Pledged Shares after payment in full of the Senior Indebtedness and the termination of the Senior Credit Agreement and the Indenture) until such date as the Agent and/or the Senior Lenders and/or the Trustee on behalf of the Senior Subordinated Noteholders cease such efforts. If at any time the Agent, the Senior Lenders or the Trustee, on behalf of the Senior Subordinated Noteholder should begin or resume to actively pursue the exercise of their Rights under the Loan Documents or the Indenture or the Subordinated Guaranties, including the conducting of a sale of any of the Collateral by the Agent or any Senior Lender, then the Investors shall again cease taking any actions permitted hereunder. In the event of a dispute with respect to this provision, it shall be the Investors' burden of proof that the Agent or the Senior Lenders or the Trustee on behalf of the Senior Subordinated Noteholders have failed or ceased to actively pursue the exercise of the Rights as described herein. 9.

If at any time hereafter, Agent and the Senior Lenders shall, in their own judgment, determine to discontinue the extension of credit to the Companies, they may do so. This Agreement shall continue in full force and effect until the Senior Indebtedness shall have been indefeasibly paid in full in cash and the Senior Credit Agreement and the Indenture have been terminated. Notwithstanding the foregoing, Agent and the Senior Lenders agree that they shall not, without the prior consent of Investors holding a majority in interest of the Preferred Stock, modify the Loan Documents (a) to increase the rates of interest payable thereunder above the default rate of interest prescribed by Section 4.1(c) of the Senior Credit Agreement; provided that this clause shall not restrict or prohibit the Agent or the Senior Lenders from charging fees in connection with the Loan Documents, amendments or waivers relating thereto and/or in connection with any over-advance facility that may be extended from time to time in the Senior Lenders' discretion, (b) amend or modify the Senior Credit Agreement so as to further restrict Radio One's ability to make interest or dividend payments on the Subordinated Obligations, (c) to increase the Senior Indebtedness in violation of Section 1.2 hereof or (d) extend the maturity date past the maturity date of the Subordinated Obligations. 14.

The Trustee shall notify Radio One promptly of any claim for which it may seek indemnity. Failure by the Trustee so to notify Radio One shall not relieve Radio One of its obligations hereunder. Radio One shall defend the claim and the Trustee may have separate 12 counsel and Radio One shall pay the fees and expenses of such counsel. Radio One need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee's own wilful misconduct, negligence or bad faith. 15.

The liability of the Investors hereunder shall be reinstated and revived, and the rights of the holders of the Senior Indebtedness shall continue, with respect to any amount at any time paid on account of the Senior Indebtedness which shall thereafter be required to be restored or returned by the holders of the Senior Indebtedness in any Reorganization (including without limitation, any repayment made pursuant to any provision of Chapter 5 of Title 11, United States Code), all as though such amount had not been paid. 18.
