Notwithstanding the foregoing, no Holder may Transfer any Lock-Up Shares for which the Lock-Up Term has terminated as a result of the satisfaction of the Price Condition (x) until the Shelf Registration Statement (as defined in the Registration Rights Agreement) is declared effective by the U.S. Securities and Exchange Commission or (y) unless pursuant to an available exemption from registration under the Securities Act of 1933, as amended.

(b) Notwithstanding the foregoing restrictions on Transfer set forth in Section 2(a), each Holder may:

(i) Transfer its Lock-Up Shares to any Permitted Transferee; and

(ii) exercise any options or warrants to purchase shares of BRPA Common Stock (which exercises may be effected on a cashless basis to the extent the instruments representing such options or warrants permit exercises on a cashless basis); provided, however, that such Holder shall otherwise comply with any restrictions on Transfer applicable to such underlying shares of BRPA Common Stock;

(iii) enter any trading plan providing for the sale of shares of BRPA Common Stock by such Holder, which trading plan meets the requirements of Rule 10b5-1(c) under the Securities Exchange Act of 1934, as it may be amended from time to time; provided, however, that such plan does not provide for, or permit, the sale of any BRPA Common Stock during the Lock-Up Term and no public announcement or filing is voluntarily made or required regarding such plan during the Lock-Up Term;

provided, however, that in the case of any Transfer or distribution pursuant to Subsection 2(b)(i), (x) in each case, such Permitted Transferees must enter into a written agreement agreeing to be bound by this Agreement, including the restrictions on Transfer set forth in Section 2(a), and (y) such Permitted Transferee (other than a Permitted Transferee as defined in clause (E) or (F) of the definition of Permitted Transferee) agrees to promptly Transfer such Lock-Up Shares back to such Holder if such Permitted Transferee ceases to be a Permitted Transferee for any reason prior to the date such Lock-Up Shares become freely transferable.

Section 3. General Provisions.

(a) Amendments and Waivers. The provisions of this Agreement may be amended, modified or waived only with the prior written consent of BRPA and Holders representing a majority of the Lock-Up Shares; provided that (i) no such amendment, modification or waiver that would adversely affect a Holder in a manner that is different from any other Holder shall be effective against such Holder without the prior written consent of such Holder and (ii) if any amendment, modification, waiver or release of this Agreement provides any Holder with rights superior to the rights provided to other Holders, such amendment, modification or waiver shall provide such rights to all Holders of Lock-Up Shares. The failure or delay of any Person to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such Person thereafter to enforce each and every provision of this Agreement in accordance with its terms. A waiver or consent to or of any breach or default by any Person in the performance by that Person of his, her or its obligations under this Agreement shall not be deemed to be a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person under this Agreement.

(b) Remedies. The parties to this Agreement and their successors and assigns shall be entitled to enforce their rights under this Agreement specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto and their successors and assigns agree and acknowledge that a breach of this Agreement would cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and remedies existing hereunder, any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this Agreement.

(c) Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited, invalid, illegal or unenforceable in any respect under any applicable law or regulation in any jurisdiction, such prohibition, invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or in any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such jurisdiction as if such prohibited, invalid, illegal or unenforceable provision had never been contained herein.

(d) Entire Agreement. Except as otherwise provided herein, this Agreement contains the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any way.

(e) Successors and Assigns. This Agreement shall bind and inure to the benefit and be enforceable by BRPA and its successors and assigns and the Holders and their respective successors and assigns (whether so expressed or not). In addition, whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit Holders are also for the benefit of, and enforceable by, any subsequent or successor Holder.

(f) Notices. Any notice, demand or other communication to be given under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given or delivered (i) when delivered personally to the recipient, (ii) when sent by confirmed electronic mail if sent during normal business hours of the recipient but, if not, then on the next Business Day, (iii) one Business Day after it is sent to the recipient by reputable overnight courier service (charges prepaid) or (iv) three Business Days after it is mailed to the recipient by first class mail, return receipt requested.
