11

(iv)Notwithstanding any other provision of this Agreement, if the Commission limits the number of Registrable Shares permitted to be registered on a particular Registration Statement (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater number of Registrable Shares), unless otherwise directed in writing by any Investor as to its Registrable Shares, the number of Registrable Shares to be registered on such Registration Statement will be reduced as follows:

(1)First, the Company shall reduce or eliminate any securities to be included other than Registrable Shares;

(2)Second, the Company shall reduce Registrable Shares (applied to the Investors on a pro rata basis based on the total number of unregistered Registrable Shares held by such Investors).

In the event of a cutback hereunder, the Company shall give the Investors at least three (3) Business Days prior written notice along with the calculations as to such Investor’s allotment.

(b)Fees and Expenses. All expenses incurred by the Company in complying with Section 9(a), including all registration, qualification and filing fees, printing expenses, fees and expenses of counsel for the Company, blue sky fees and expenses and the expense of any special audits incident to or required by any such registration (but excluding the fees of legal counsel for any Investor or any holder of Registrable Shares) shall be borne by the Company. All selling commissions applicable to the sale of Registrable Shares and all fees and expenses of legal counsel for any Investor or any holder of Registrable Shares related to the registration and sale of the Registrable Shares shall be borne by the Investor or holder of Registrable Shares incurring such commissions, fees or expenses; provided, however, that the Company shall pay the fees and expenses of one counsel for all Investors selling shares in such registration.

12

(c)Certain Actions and Notifications. In the case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Agreement, the Company shall, upon reasonable request, inform the Investors as to the status of such registration, qualification, exemption and compliance. At its expense the Company shall:

(i)except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under State Securities Laws which the Company determines to obtain, continuously effective with respect to the Investors, and to keep the applicable Registration Statement effective until the earlier of (A) two (2) years from the Closing Date, (B) the date by which all the Registrable Shares may be sold without volume or manner of sale restrictions which may be applicable to affiliates under Rule 144, or (C) the date on which all of the Registrable Shares are sold. The period of time during which the Company is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period”;

(ii)advise the Investors within five (5) Business Days:

(1)when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any post-effective amendment thereto has become effective;

(2)of any request by the Commission for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information;

(3)of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or, to the Company’s knowledge, the initiation of any proceedings for such purpose;

(4)of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Shares included therein for sale in any jurisdiction or, to the Company’s knowledge, the initiation or threatening of any proceeding for such purpose; and

(5)subject to the provisions of this Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein do not include any untrue statement of a material fact and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading;

(iii)use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iv)if any Investor so requests in writing, promptly furnish to such Investor, without charge, at least one copy of each Registration Statement and each post-effective amendment thereto, including financial statements and schedules, and, if explicitly requested, all exhibits in the form filed with the Commission;

13

(v)during the Registration Period, promptly deliver to the Investors, without charge, as many copies of each prospectus included in a Registration Statement and any amendment or supplement thereto as any Investor may reasonably request in writing; and the Company consents to the use, consistent with the provisions hereof, of the prospectus or any amendment or supplement thereto by such Investor of Registrable Shares in connection with the offering and sale of the Registrable Shares covered by a prospectus or any amendment or supplement thereto;

(vi)during the Registration Period, if any Investor so requests in writing, deliver to such Investor, without charge, (i) one copy of the following documents, other than those documents available via the Commission’s EDGAR system: (A) its annual report on Form 10-K (or similar form), (B) its definitive proxy statement with respect to its annual meeting of stockholders, (C) each of its quarterly reports on Form 10-Q, and (D) a copy of each full Registration Statement (the foregoing, in each case, excluding exhibits); and (ii) if explicitly requested, all exhibits excluded by the parenthetical to the immediately preceding clause (D); provided, that the Company shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system;

(vii)prior to any public offering of Registrable Shares pursuant to any Registration Statement, promptly take such actions as may be necessary to register or qualify or obtain an exemption for offer and sale under State Securities Laws of such United States jurisdictions as any Investor reasonably request in writing; provided that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction, and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Registrable Shares covered by any such Registration Statement;

(viii)upon the occurrence of any event contemplated by Section 9(c)(ii)(5), except for such times as the Company is permitted hereunder to suspend the use of a prospectus forming part of a Registration Statement, and taking into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders of the premature disclosure of such event, the Company shall use its commercially reasonable efforts to prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ix)otherwise use its commercially reasonable efforts to comply in all material respects with all applicable rules and regulations of the Commission which could affect the sale of the Registrable Shares;

14

(x)use its commercially reasonable efforts to cause all Registrable Shares to be listed on each securities exchange or market, if any, on which equity securities issued by the Company have been listed; and

(xi)cooperate with any broker-dealer through which any Investor proposes to resell its Registrable Shares in such broker-dealer’s filing with the FINRA Corporate Financing Department pursuant to FINRA Rule 5110, as requested by such Investor.

(d)No Delays. The Investors shall not have the right to take any action to restrain, enjoin or otherwise delay any registration pursuant to Section 9(a) as a result of any controversy that may arise with respect to the interpretation or implementation of this Agreement.

(e)Special Interest. If the Company has not (i) filed the Initial Registration Statement by the Filing Date or (ii) effected the registration of the Registrable Shares by the Effectiveness Date (each such event referred to in clauses (i) and (ii), a “Registration Default”) or (iii) after the effective date of a Registration Statement, such Registration Statement ceases for any reason to remain continuously effective as to all Registrable Securities included in such Registration Statement, or the Holders are otherwise not permitted to utilize the Prospectus therein to resell such Registrable Securities, for more than 20 consecutive calendar days or more than an aggregate of 35 calendar days (which need not be consecutive calendar days) during any 12-month period (any such failure or breach under clause (iii) being referred to as a “Lapse Event” and, for purpose of clause (iii) the date on which such 20 or 35 calendar day period, as applicable, is exceeded being referred to as “Event Date”), then the Company shall pay to the Investors interest (“Special Interest”), not as a penalty, in an amount, with respect to clauses (i) and (ii) per annum equal to 0.15% of such Investor’s Purchase Price for each day that the Registration Default continues and, with respect to clause (iii), on each such Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each Investor an amount in cash, as liquidated damages and not as a penalty, equal to 0.15% of such Investor’s Purchase Price; provided, however, that the Company shall in no event be required to pay Special Interest for more than one Registration Default at any given time and in no event shall the maximum aggregate liquidated damages payable to an Investor under this Section 9(e) exceed 4% of such Investor’s Purchase Price. A Registration Default ends upon termination of the Registration Period or, if earlier, (x) in the case of a Registration Default under clause (i) of the definition thereof, when the Initial Registration Statement is filed with the Commission or (y) in the case of a Registration Default under clause (ii) of the definition thereof, when the Initial Registration Statement becomes or is declared effective by the Commission. All accrued Special Interest shall be paid by the Company to each Investor on a quarterly basis to an account designated in writing by such Investor. Notwithstanding anything contained herein to the contrary, the payment of Special Interest shall be the only remedy available to the Investor for any Registration Default.

15

(f)Indemnification.

(i)To the extent permitted by law, the Company shall indemnify each Investor and each person controlling such Investor within the meaning of Section 15 of the Securities Act, with respect to which any registration that has been effected pursuant to this Agreement, against all claims, losses, damages and liabilities (or action in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 9(f)(iii)), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, any amendment or supplement thereof, or other document incident to any registration, qualification or compliance or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, or any violation by the Company of any rule or regulation promulgated by the Securities Act applicable to the Company and relating to any action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse such Investor and each person controlling such Investor, for reasonable legal and other out-of-pocket expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred; provided that the Company will not be liable in any such case to the extent that any untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Investor for use in preparation of any Registration Statement, prospectus, amendment or supplement; provided however, that the Company will not be liable in any such case where the claim, loss, damage or liability arises out of the failure of such Investor to comply with the covenants and agreements contained in this Agreement respecting sales of Registrable Shares, and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus but eliminated or remedied in the amended prospectus on file with the Commission at the time any Registration Statement becomes effective or in an amended prospectus filed with the Commission pursuant to Rule 424(b) which meets the requirements of Section 10(a) of the Securities Act (each, a “Final Prospectus”), such indemnity shall not inure to the benefit of such Investor or any such controlling person, if a copy of a Final Prospectus furnished by the Company to such Investor for delivery was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and a Final Prospectus would have cured the defect giving rise to such loss, liability, claim or damage.

(ii)Each Investor shall, severally and not jointly, indemnify the Company, each of its directors and officers, and each person who controls the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 9(f)(iii)), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, any amendment or supplement thereof, or other document incident to any such registration, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, and will reimburse the Company, such directors and officers, and each person controlling the Company for reasonable legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred, in each case to the extent, but only to the extent, that such untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Investor expressly for use in the Registration Statement or any prospectus, amendment or supplement filed thereunder for the Registrable Shares of such Investor. Notwithstanding the foregoing, the maximum liability of such Investor under this section shall be limited to the net proceeds received by such Investor from the sale of Registrable Shares.

16

(iii)Each party entitled to indemnification under this Section 9(f) (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld, conditioned or delayed), and the Indemnified Party may participate in such defense at such Indemnified Party’s expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement, unless such failure is materially prejudicial to the Indemnifying Party in defending such claim or litigation. An Indemnifying Party shall not be liable for any settlement of an action or claim effected without its written consent (which consent shall not be unreasonably withheld, conditioned or delayed). No Indemnifying Party, in its defense of any such claim or litigation, shall, except with the consent of each Indemnified Party (which consent shall note be unreasonably withheld, conditioned or delayed), consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

(iv)If the indemnification provided for in this Section 9(f) is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 9(f) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 9(f), no Investor shall be required to contribute pursuant to this Section 9(f), in the aggregate, any amount in excess of the amount by which the net proceeds actually received by such Investor from the sale of the Registrable Shares exceeds the amount of any damages that such Investor has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

17

(g)Disclosure, Etc.

(i)Not less than five (5) Business Days prior to the filing of each Registration Statement, the Company shall furnish to each Investor copies of such Registration Statement and all exhibits being filed therewith, and shall consider in good faith the reasonable comments of such Investor. For purposes of clarification, the Company shall not be obligated to provide the Investors advance copies of any universal shelf registration statement registering securities in addition to those required hereunder.

(ii)Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event requiring the preparation of a supplement or amendment to a prospectus relating to Registrable Shares so that, as thereafter delivered to the Investor, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, such Investor will forthwith discontinue disposition of Registrable Shares pursuant to a Registration Statement and prospectus contemplated by Section 9(a) until its receipt of copies of the supplemented or amended prospectus from the Company and, if so directed by the Company, such Investor shall deliver to the Company all copies, other than permanent file copies then in such Investor’s possession, of the prospectus covering such Registrable Shares current at the time of receipt of such notice.

(iii)Each Investor shall suspend, upon request of the Company, any disposition of Registrable Shares pursuant to any Registration Statement and prospectus contemplated by Section 9(a) during the occurrence or existence of any pending corporate development with respect to the Company that the Board of Directors of the Company believes in good faith may be material and that, in the determination of the Board of Directors of the Company, makes it not in the best interest of the Company to allow continued availability of a Registration Statement or prospectus. The Company shall be entitled to exercise its right under this paragraph to suspend the availability of a Registration Statement and prospectus for a period not to exceed 60 calendar days (which need not be consecutive days) in any 12-month period.

(iv)Upon the occurrence of any event contemplated by Section 9(g)(iii), as promptly as reasonably possible under the circumstances taking into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders of the premature disclosure of such event, the Company shall prepare a supplement or amendment, including a post-effective amendment, to a Registration Statement or a supplement to the related prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither a Registration Statement nor such prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The Company will use its best efforts to ensure that the use of the prospectus may be resumed as promptly as is practicable. The Company shall be entitled to exercise its right under this Section 9(g) to suspend the availability of a Registration Statement and prospectus for a period not to exceed 60 calendar days (which need not be consecutive days) in any 12-month period.

18

(v)As a condition to the inclusion of its Registrable Shares, each Investor shall furnish to the Company such information regarding such Investor and the distribution proposed by such Investor as the Company may reasonably request in writing, including completing a Registration Statement Questionnaire in the form provided by the Company, or as shall be required in connection with any registration referred to in this Section 9.

(vi)Each Investor hereby covenants with the Company not to make any sale of the Registrable Shares without effectively causing the prospectus delivery requirements under the Securities Act to be satisfied (unless such sale is pursuant to Rule 144).

(vii)Each Investor agrees not to take any action with respect to any distribution deemed to be made pursuant to a Registration Statement which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or law.

(viii)At the end of the Registration Period, each Investor shall discontinue sales of shares pursuant to any Registration Statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by any such Registration Statement which remain unsold, and the Investors shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company.

(h)Assignment. The rights to cause the Company to register Registrable Shares granted to the Investors by the Company under Section 9(a) may be assigned by any Investor in connection with a transfer by such Investor of all or a portion of its Registrable Shares, provided, however, that such Investor must give the Company at least 10 days prior notice of such transfer for such transfer to be reflected in the Registration Statement or any amendment thereto and that (i) such transfer may otherwise be effected in accordance with applicable securities laws; (ii) such Investor gives prior written notice to the Company at least 10 days prior to the transfer; and (iii) such transferee agrees to comply with the terms and provisions of this Agreement, and such transfer is otherwise in compliance with this Agreement. Except as specifically permitted by this Section 9(h), the rights of an Investor with respect to Registrable Shares as set out herein shall not be transferable to any other person, and any attempted transfer by any Investor shall cause all rights of such Investor therein to be forfeited.

(i)Waivers. The rights of any Investor under any provision of this Section 9 may be waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely) or amended by an instrument in writing signed by such Investor.

10.Investors’ Covenant to Convert. Promptly (and in any event within 10 Business Days) following (a) the effectiveness of a registration statement covering the resale of the Conversion Shares under the Securities Act, and (b) June 30 of each year, each Investor shall submit a Notice of Conversion (as defined in the Certificate of Designations) to the Company in accordance with Section 6 of the Certificate of Designations to effect a conversion of the Series A Preferred Stock such that following such conversion such Investor will either (x) have converted all of the remaining shares of Series A Preferred Stock owned by such Investor, or (y) own a number of shares of Common Stock equal to the Beneficial Ownership Limit (as defined in the Certificate of Designations) applicable to such Investor.

provided, that the Company shall (a) cause such legend to be promptly removed once a registration statement covering the resale of any Securities is effective under the Securities Act or if such legend is no longer required under applicable law and (b) in connection with any sale made under the Registration Statement or Rule 144, promptly (and in any event within five (5) Business Days after receipt by the Company of a request therefor accompanied by all reasonably required documentation) deliver, or cause to be delivered, to any Investor new certificate(s) representing the Conversion Shares that are free from all restrictive and other legends or, at the request of such Investor, via DWAC transfer to such Investor’s account.

12.Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

13.Certain Transactions. Each Investor, severally and not jointly, covenants that neither it, nor any affiliate acting on its behalf or pursuant to any understanding with it, will execute any purchases or sales, including short sales, of any of the Company’s securities during the period commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 8(b).

20

16.Assignability. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Investors. Subject to Section 9(h), any Investor may assign any or all of its rights under this Agreement to any person to whom such Investor assigns or transfers any Securities; provided that such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions of this Agreement that apply to the “Investors”.

17.Waiver of Jury Trial. THE COMPANY AND EACH INVESTOR IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY LEGAL PROCEEDING ARISING OUT OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

Each Investor shall be entitled to independently protect and enforce its rights, including the rights arising out of this Agreement, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose.

ANNEX I

RULE 506 DISCLOSURE

The following is a description of matters that are required to be disclosed pursuant to an undertaking to which Oppenheimer & Co. Inc. (“Oppenheimer”) is subject or pursuant to Rule 506(e) adopted under the Securities Act of 1933, as amended, with respect to Oppenheimer and its financial advisors who may be paid for soliciting sales of securities pursuant to Rule 506.

1.             On February 26, 2010 Oppenheimer entered into a Consent Order with the Massachusetts Securities Division (the “Division”). The Order concerned alleged violations of the Massachusetts Uniform Securities Act with respect to Oppenheimer’s sale of auction rate securities. The order found that Oppenheimer violated Section 204(a)(2)(G) of Chapter 110A of Massachusetts General Laws. Oppenheimer was required to buy back illiquid auction rate securities from investors and pay hearing costs in an amount totaling $250,000.

2.             On July 9, 2007 Oppenheimer entered into a Consent Order with the Massachusetts Securities Division (the “Division”). The Order alleged that Oppenheimer failed to supervise a registered representative who engaged in unlawful activities. The Division alleged that Oppenheimer made false and misleading filings to the Division during the course of its investigation of the matters addressed in the Order and accordingly violated Massachusetts General Laws, Chapter 110A, Section 404. Oppenheimer was required to pay a fine of $1,000,000, make restitution to the investor, cease and desist from further violations and retain an independent consultant.

3.             On January 27, 2015, Oppenheimer entered into an order with the Securities and Exchange Commission (“SEC”) pursuant to which Oppenheimer was censured and agreed to (i) pay $10 million, comprised of $4,168,400 in disgorgement, $753,471 in prejudgment interest and $5,078,129 in civil penalties; (ii) cease and desist from committing or causing any violations of Sections 15(a) and 17(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) and Rules 17a-3 and 17a-8 adopted thereunder and of Section 5 of the Securities Act of 1933 (the “Securities Act”); and (iii) retain an independent consultant over a five-year period to conduct a review of Oppenheimer’s policies and procedures as they relate to compliance with Section 5 of the Securities Act, the Bank Secrecy Act, the Patriot Act, Oppenheimer’s AML program and the proper recognition of liabilities and expenses associated with foreign entities trading on behalf of customers and U.S. customers trading through foreign financial institutions. This settlement was based on Oppenheimer’s conduct relating to two separate customer accounts. The first account involved aiding and abetting a customer’s violation of the broker-dealer registration requirements under the Exchange Act, failure to file Suspicious Activity Reports to report potential misconduct by this customer and failure to properly report, withhold and recognize backup withholding taxes. The second account involved failure to respond to red flags and conduct an inquiry into whether a customer’s unregistered sales of penny stocks were exempt from Securities Act registration requirements and failure to reasonably supervise with a view toward detecting and preventing violations of the registration provisions. Oppenheimer also agreed to pay an additional $10 million in civil penalties to settle a parallel action by the Treasury Department’s Financial Crimes Enforcement Network.
