The Company and its subsidiaries maintain internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as disclosed, or incorporated by reference, in each of the Time of Sale Information and the Offering Memorandum, there are no material weaknesses or significant deficiencies in the Company’s internal control over financial reporting.

     (dd) Insurance. The Company and its Significant Subsidiaries have insurance covering their respective properties, operations, personnel and businesses, including business interruption insurance, which insurance is in amounts and insures against such losses and risks as the Company has determined are adequate in all material respects to protect the Company and its subsidiaries and their businesses, taken as a whole; and neither the Company nor any of its Significant Subsidiaries has (i) received notice from any insurer or agent of such insurer that capital improvements or other expenditures are required or necessary to be made in order to continue such insurance or (ii) any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage at reasonable cost from similar insurers as may be necessary to continue its business, except as would not reasonably be expected to result in a Material Adverse Effect.

     (ee) No Unlawful Payments. Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company and the Guarantors, any director, officer, agent, employee or other person acting on behalf of the Company or any of its subsidiaries has during the last five years (i) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity; (ii) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; (iii) violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977, as amended; or (iv) made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment except as would not reasonably be expected to have a Material Adverse Effect.

     (ff) Compliance with Anti-Money Laundering Laws. The operations of the Company and its subsidiaries are and have been conducted at all times in compliance in all material respects with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the anti-money laundering statutes of all jurisdictions to which the Company and its subsidiaries are subject, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency having authority over the Company and its subsidiaries (collectively, the “Anti-Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries with respect to the Anti-Money Laundering Laws is pending or, to the knowledge of the Company, threatened except as would not reasonably be expected to have a Material Adverse Effect.

     (gg) Compliance with OFAC. None of the Company, any of its subsidiaries or, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”); and the Company will not directly or indirectly use the proceeds of the offering of the Securities hereunder, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions

administered by OFAC except as would not reasonably be expected to have a Material Adverse Effect.

     (hh) Solvency. On and immediately after the Closing Date, the Company (after giving effect to the issuance of the Securities and the other transactions related thereto as described in each of the Time of Sale Information and the Offering Memorandum) will be Solvent.

     (ii) No Restrictions on Subsidiaries.

     (jj) No Broker’s Fees. Neither the Company nor any of its subsidiaries is a party to any contract, agreement or understanding with any person (other than this Agreement) that would give rise to a valid claim against any of them or any Initial Purchaser for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Securities (other than as provided in this Agreement).

On the Closing Date, the Securities will not be of the same class as securities listed on a national securities exchange registered under Section 6 of the Exchange Act or quoted in an automated inter-dealer quotation system; and each of the Preliminary Offering Memorandum and the Offering Memorandum, as of its respective date, contains or will contain all the information that, if requested by a

     (mm) No General Solicitation or Directed Selling Efforts. None of the Company or any of its affiliates or any other person acting on its or their behalf (other than the Initial Purchasers, as to which no representation is made) has (i) solicited offers for, or offered or sold, the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act or (ii) engaged in any directed selling efforts within the meaning of Regulation S under the Securities Act (“Regulation S”), and all such persons have complied with the offering restrictions requirement of Regulation S.

     (nn) Securities Law Exemptions. Assuming the accuracy of the representations and warranties of the Initial Purchasers contained in Section 1(b) (including Annex C hereto) and their compliance with their agreements set forth therein, it is not necessary, in connection with the issuance and sale of the Securities to the Initial Purchasers and the offer, resale and delivery of the Securities by the Initial Purchasers in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum, to register the Securities under the Securities Act or to qualify the Indenture under the Trust Indenture Act.

     (ss) Sarbanes-Oxley Act.

     (tt) Amended and Restated Credit Facility. The Amended and Restated Credit Facility has been fully and validly authorized by the Company and the Guarantors and, when duly executed and delivered by the Company and the Guarantors and assuming the Amended and Restated Credit Facility is a valid and binding agreement of each of the other parties thereto, will be the valid and legally binding obligation of the Company and the Guarantor, enforceable against the Company and the Guarantors in accordance with its terms, subject to the Enforceability Exception.

connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto) or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representative expressly for use therein, it being understood and agreed that the only such information consists of the following: the information in the fourth sentence of the eleventh paragraph and the thirteenth paragraph under the heading “Plan of Distribution” in the Preliminary Offering Memorandum and the Offering Memorandum.

     (b) Indemnification of the Company. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors, each of their respective directors and officers and each person, if any, who controls the Company or the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto), it being understood and agreed that the only such information consists of the following: the information in the fourth sentence of the eleventh paragraph and the thirteenth paragraph under the heading “Plan of Distribution” in the Preliminary Offering Memorandum and the Offering Memorandum.

     (c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel

reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by the Representative and any such separate firm for the Company, the Guarantors, their respective directors and officers and any control persons of the Company and the Guarantors shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

     (d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company and the Guarantors on the one hand and the Initial Purchasers on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Guarantors or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

     (e) Limitation on Liability. The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other reasonable expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

     (f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

     8. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange (the “NYSE”) or NASDAQ; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on the NYSE or NASDAQ; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery, of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum.

     9. Defaulting Initial Purchaser.

     (a) If, on the Closing Date, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non defaulting Initial Purchasers or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

     (b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder plus such

Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

     (c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company or the Guarantors, except that the Company and the Guarantors will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

     (d) Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company, the Guarantors or any non-defaulting Initial Purchaser for damages caused by its default.

     10. Payment of Expenses.

     (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and the Guarantors jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer Written Communication and the Offering Memorandum (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s and the Guarantors’ counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and Collateral Agent and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (x) (i) all filing costs and expenses relating to the granting and perfection of the security interests in the Collateral, as set forth in the Pledge Agreement and (ii) the reasonable fees and expenses of counsel for the Initial Purchasers in connection with all matters relating to the granting and perfection of security interests in the Collateral for the

Securities (including, without limitation, the Intercreditor Agreement) in an amount not to exceed $100,000 (provided reasonably detailed invoices are provided).

     (b) If (i) this Agreement is terminated pursuant to Section 8, (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company and the Guarantors jointly and severally agree to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby.

     11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, officers and directors of each Initial Purchaser and the Company and the Guarantors referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor by reason of such purchase.

     12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Guarantors and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company, the Guarantors or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Guarantors or the Initial Purchasers.

For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the term “Exchange Act” means the Securities Exchange Act of 1934, as amended; (d) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (e) the term “written communication” has the meaning set forth in Rule 405 under the Securities Act.

The Letter Agreement also assigns all of Schonfeld’s responsibilities under the Asset Purchase Agreement to its parent company, SGH, and extends the initial term of Opus’s portfolio margining agreement with PFSI from April 30, 2017 to April 30, 2019. The foregoing description of the Letter Agreement is qualified in its entirety by reference to the Letter Agreement, a copy of which is included as Exhibit 2.1 to the Company’s 8-K filed on April 28, 2010, which is incorporated by reference herein.

Re:       12.5% Senior Second Lien Secured Notes due 2017 of Penson Worldwide, Inc.

Ladies and Gentlemen:

     We have acted as special counsel for Penson Worldwide, Inc., a Delaware corporation (the “Company”) in connection with the Purchase Agreement, dated April 29, 2010 (the “Purchase Agreement”), among the Company, SAI Holdings, Inc. (“SAI”), Penson Holdings, Inc. (“Holdings”) and J.P. Morgan Securities Inc., as representative of the Initial Purchasers (as defined in the Purchase Agreement). All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Purchase Agreement. This opinion is being delivered to you pursuant to Section 6(f) of the Purchase Agreement.

     In connection with the opinions expressed below, we have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the certificate of incorporation of the Company and Holdings, (ii) the bylaws of the Company and Holdings, (iii) the Purchase Agreement, (iv) the Indenture, (v) the Securities issued on the date hereof, (vi) the Intercreditor Agreement, (vii) the Pledge Agreement (the documents referred to in (iii) through (vii), collectively, the “Transaction Documents”) (viii) the Time of Sale Information, (ix) the Offering Memorandum and (x) such other documents and records as we have deemed appropriate for the purposes of the opinions set forth herein.

     We have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of the documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as certified, facsimile or photostatic copies and the authenticity of the originals of all documents submitted to us as copies. We have also assumed (i) that the Purchase Agreement, the Indenture, the Intercreditor Agreement and the Pledge Agreement constitute valid and binding obligations of each party thereto, other than the Company and Holdings, and (ii) the due authorization, execution and delivery of each of the

Transaction Documents by each party thereto, other than the Company and Holdings, in accordance with the laws of its jurisdiction of incorporation or organization.

As to any facts that are material to the opinions hereinafter expressed that we did not independently establish or verify, we have relied, without investigation, upon the representations of the Company, SAI and Holdings contained in the Purchase Agreement and upon certificates of officers of the Company and Holdings.

     In rendering the opinions and making the statements set forth herein, whenever an opinion or statement herein is qualified by “to our knowledge,” “known to us” or by words of similar import, it is intended to indicate that, during the course of our representation of the Company in the subject transaction, no information has come to the attention of those lawyers in our firm who have rendered legal services in connection with the transactions contemplated by the Offering Memorandum that gives us actual knowledge of the inaccuracy of such statement or opinion. Except as specifically set forth herein, we have not undertaken any independent investigation to determine the accuracy of facts material to any such statement or opinion, and no inference as to such statement or opinion should be drawn from the fact of our representation of the Company. In making judgments in respect of matters of materiality, we have, to the extent we deemed appropriate, relied upon management and other representatives of the Company in assessing the possible impact of such items upon the Company.

     Based upon and subject to the foregoing and to the limitations and qualifications described below, we are of the opinion that:

(a) The Company and Holdings have been duly organized and are validly existing and in good standing under the laws of the State of Delaware, are duly qualified to do business and are in good standing in each jurisdiction listed on Schedule 2 hereto, and have all corporate power and authority to own, lease and operate their respective properties and to conduct the businesses as described in the Time of Sale Memorandum and the Offering Memorandum.

(d) The Indenture has been duly authorized, executed and delivered by the Company and Holdings and, assuming due execution and delivery thereof by SAI and the Trustee and Collateral Agent, constitutes a valid and legally binding agreement of the Company and the Guarantors enforceable against the Company and the Guarantors in accordance

with its terms; and the Indenture conforms in all material respects with the requirements of the Trust Indenture Act and the rules and regulations of the Commission applicable to an indenture that is qualified thereunder.

(e) The Securities have been duly authorized, executed and delivered by the Company and, when duly authenticated as provided in the Indenture and paid for as provided in the Purchase Agreement, will be duly and validly issued and outstanding and will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, subject to the Enforceability Exceptions, and will be entitled to the benefits of the Indenture; and the Guarantee has been duly authorized by Holdings and, assuming due authorization by SAI of the Guarantee, when the Guarantees have been duly executed, authenticated, issued and delivered as provided in the Indenture and paid for as provided in the Purchase Agreement, will be valid and legally binding obligations of the Guarantors, enforceable against the Guarantors in accordance with their terms, subject to the Enforceability Exceptions, and will be entitled to the benefits of the Indenture.

(f) The Purchase Agreement has been duly authorized, executed and delivered by the Company and Holdings.

(g) The Pledge Agreement has been duly authorized, executed and delivered by the Company and Holdings and, assuming due authorization, execution and delivery thereof by SAI, and constitutes a valid and legally binding agreement of the Company and the Guarantors enforceable against the Company and the Guarantors in accordance with its terms.

To ensure compliance with the requirements imposed by the Internal Revenue Service, we inform you (i) that any United States federal tax advice contained in this communication (including any attachment) is not intended or written to be used, and cannot be used, by any taxpayer for the purpose of avoiding penalties under the United States Internal Revenue Code; (ii) such advice was written in support of the promotion, marketing or recommending of the transactions or matters addressed herein and (iii) taxpayers should seek advice based on their particular circumstances from an independent tax advisor.

(o) Neither the Company nor any of its subsidiaries is, and after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in each of the Time of Sale Information and the Offering Memorandum none of them will be required to register as, an “investment company” as defined in the Investment Company Act.

(p) Neither the issuance, sale and delivery of the Securities nor the application of the proceeds thereof by the Company as described in each of the Time of Sale Information and the Offering Memorandum will violate Regulation T, U or X of the Board of Governors of the Federal Reserve System or any other regulation of such Board of Governors.

(q) Assuming the accuracy of the representations and warranties, and the compliance with the agreements, of the Company, the Guarantors and the Initial Purchasers contained in the Purchase Agreement, it is not necessary, in connection with the issuance and sale of the Securities to the Initial Purchasers and the initial offer, resale and delivery of the Securities by the Initial Purchasers in the manner contemplated by the Purchase Agreement, the Time of Sale Information and the Offering Memorandum, to register the Securities under the Securities Act or to qualify the Indenture under the Trust Indenture Act.

     Our opinions expressed above are subject to the following limitations, exceptions, qualifications and assumptions:

1. For purposes of our opinions in paragraph (a) above as to the valid existence and good standing of the Company and Holdings and the due qualification of the Company and Holdings to do business as a foreign corporation in each jurisdiction in which their respective ownership or lease or property or the conduct of their respective businesses requires such qualification, we have relied solely upon good standing or similar certificates issued by appropriate authorities in the subject jurisdictions.

2. The enforceability opinions expressed in paragraphs (d), (e), (g), (h) and (s) above are subject to bankruptcy, insolvency, fraudulent transfer and other similar laws affecting the rights and remedies of creditors generally and general principles of equity, including concepts of materiality, reasonableness, good faith and fair dealing.

3. Rights to indemnification and contribution in the Purchase Agreement may be limited by applicable securities laws and principles of public policy.

4. For purposes of the opinions in paragraphs (j) and (k) above, we have considered only such laws and regulations that in our experience are typically applicable to a transaction of the nature contemplated by the Purchase Agreement.

5. For the purposes of the opinions expressed in clause (i) of paragraph (j), certain of the agreements listed on Schedule 3 state that they are governed by the laws of jurisdictions other than the laws of the State of New York. We have made no investigation of any such other laws or consulted with counsel admitted to practice law in such jurisdictions. We have not examined the question of what law would govern the interpretation or enforcement of any such agreement and have merely assumed that they would be interpreted in accordance with their plain meaning. We have not reviewed the covenants in the any such agreement that contain financial ratios or other financial restrictions and no opinion is provided with respect thereto.

6. Our opinion regarding tax matters set forth in paragraph (l) hereof is based upon existing law, regulations, administrative pronouncements and judicial authority, all as in effect as of today’s date. It represents our best legal judgment as to the matters addressed

therein, but is not binding on the Internal Revenue Service or the courts. Accordingly, no assurance can be given that the opinion expressed therein, if contested, would be sustained by a court. Furthermore, the authorities upon which we rely may be changed at any time with retroactive effect. No assurances can be given as to the effect of any such change on our opinion.

7. In connection with the opinions set forth in paragraphs (r), (s), (t), and (u), we have assumed that each of the Pledgors has, or has power to transfer, rights (to the extent necessary to grant a security interest) in the Collateral (as defined in the Pledge Agreement) existing on the date hereof and will have, or will have the power to transfer, rights (to such extent) in property which becomes the Collateral (as defined in the Pledge Agreement) after the date hereof.

8. In connection with the opinions set forth in paragraphs (s) and (u), the perfection of a security interest in any collateral consisting of “proceeds” (as defined in the Texas UCC) is subject to limitations set forth in Section 9-315 of the Texas UCC.

9. In connection with the opinions set forth in paragraphs (r) and (t), the perfection of a security interest in any collateral consisting of “proceeds” (as defined in the Delaware UCC) is subject to limitations set forth in Section 9-315 of the Delaware UCC.

10. Except to the extent expressly set forth in paragraph (s), we express no opinion regarding the priority of any security interest.

11. Except as expressly provided in paragraph (s), (t) and (u), we express no opinion as to the perfection of any lien on or security interest in any real or personal property, tangible or intangible, providing or intended to provide collateral security for the Notes Obligations (as defined in the Pledge Agreement).

12. The opinions expressed in this opinion letter are limited to the laws of the State of New York, the General Corporation Law of the State of Delaware, the Delaware UCC, the Texas UCC and the Federal laws of the United States of America, and we express no opinion with respect to any other laws of any state or jurisdiction. With respect to our opinions relating to the Delaware UCC and the Texas UCC, respectively, we have, with your permission, (i) confined our investigation of the Delaware UCC and the Texas UCC, respectively, to an examination of the relevant provisions of the UCC as in effect in the State of Delaware and the State of Texas, respectively, as set forth in the CCH Secured Transactions Guide (as updated through September 19, 2006) and the O’Connor’s Business and Commerce Code Plus (2009-10), without regard to any case law decided thereunder or other laws or regulations relating thereto. We note that the Intercreditor Agreement and the Pledge Agreement provide that they are to be governed by the laws of the State of New York.

     This opinion letter is effective only as of the date hereof. We do not assume responsibility for updating this opinion letter as of any date subsequent to its date, and we assume no responsibility for advising you of any changes with respect to any matters described in this opinion letter that may occur, or facts that may come to our attention, subsequent to the date hereof.

     This opinion letter is furnished by us solely for the benefit of the Initial Purchasers in connection with the transactions contemplated by the Purchase Agreement and may not be relied upon by the Initial Purchasers for any other purpose, nor may it be furnished to or relied upon by any other person or entity for any purpose whatsoever; provided, however, that U.S. Bank National Association, as Trustee under the Indenture, may rely on our opinions in paragraphs (a), (d), (e) and (q) above, subject to the limitations and qualifications set forth herein. This opinion letter is not to be quoted in whole or in part or otherwise referred to or used, nor is it to be filed with any governmental agency or any other person, without our express written consent.

Re:       12.5% Senior Second Lien Secured Notes due 2017 of Penson Worldwide, Inc.

Ladies and Gentlemen:

     We have acted as special counsel for Penson Worldwide, Inc., a Delaware corporation (the “Company”) in connection with the Purchase Agreement, dated April 29, 2010 (the “Purchase Agreement”), among the Company, SAI Holdings, Inc. (“SAI”), Penson Holdings, Inc. (“Holdings”) and J.P. Morgan Securities Inc., as representative of the Initial Purchasers (as defined in the Purchase Agreement). All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Purchase Agreement. This opinion is being delivered to you pursuant to Section 6(f) of the Purchase Agreement.

     The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Time of Sale Information and the Offering Memorandum, and we have not undertaken any obligation to verify independently any of the factual matters set forth in the Time of Sale Information and the Offering Memorandum. Moreover, many of the determinations required to be made in the preparation of the Time of Sale Information and the Offering Memorandum involve matters of a non-legal nature.

     Subject to the foregoing, we confirm to you that we have participated in conferences with officers and other representatives of the Company, representatives of the Initial Purchasers and their counsel, representatives of the independent registered public accounting firm of the Company and representatives of FTI Consulting, Inc. an advisor to the Company in connection with the Ridge Acquisition, at which conferences the contents of the Time of Sale Information and the Offering Memorandum and related matters were discussed and, although we are not passing upon and need not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Time of Sale Information and the Offering Memorandum (except as and to the extent set forth in paragraphs (i) and (l) of the opinion letter of even date herewith delivered to you by us), on the basis of the foregoing and the information disclosed to us, but without independent check and verification, and relying as to materiality on representations and statements of officers and other representatives of the Company, nothing has come to our attention that has led us to believe that the Time of Sale Information, at the Time of

Sale (which we assume to be the date of the Purchase Agreement), contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or that the Offering Memorandum, as of its date and the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that we do not express any belief with respect to the financial statements, schedules, notes, other financial and accounting data and statistical data derived therefrom, included in the Time of Sale Information or the Offering Memorandum).

     This letter is effective only as of the date hereof. We do not assume responsibility for updating this letter as of any date subsequent to its date, and we assume no responsibility for advising you of any changes with respect to any matters described in this letter that may occur, or facts that may come to our attention, subsequent to the date hereof.

     This letter is furnished by us solely for the benefit of the Initial Purchasers in connection with the transactions contemplated by the Purchase Agreement and may not be relied upon by the Initial Purchasers for any other purpose, nor may it be furnished to or relied upon by any other person or entity for any purpose whatsoever. This letter is not to be quoted in whole or in part or otherwise referred to or used, nor is it to be filed with any governmental agency or any other person, without our express written consent.

ANNEX D-2

Opinion of In-House Counsel for the Company

May 6, 2010

J.P. Morgan Securities Inc.
UBS Securities LLC
Morgan Keegan & Company, Inc.
JMP Securities LLC

Ladies and Gentlemen:

          I have acted as counsel to Penson Worldwide Inc., a Delaware corporation (the “Company”), in connection with the issuance of the Company’s ___% Senior Second Lien Secured Notes Due 2017 (the “Notes”) pursuant to that certain Indenture dated as of May 6, 2010 (the “Indenture”) among the Company, SAI Holdings, Inc., a Texas corporation (“SAI”), Penson Holdings, Inc., a Delaware corporation (“PHI”), and U.S. Bank National Association, as trustee (“Trustee”) for the holders of the Notes (the “Notes Offering”). I have also acted as counsel to Penson Financial Services, Inc., a North Carolina corporation (“PFSI”), Penson GHCO, an Illinois general partnership (“Penson GHCO”), GHP1, Inc., a Texas corporation (“GHP1”) and Penson Financial Services Canada Inc. a federal corporation incorporated under the laws of Canada (“Penson Canada,” and together with the Company, PFSI, Penson GHCO, GHP1, SAI, and PHI each a “Penson Entity” and collectively, the “Penson Entities”) in connection with the Notes Offering. This opinion letter is being delivered to you pursuant to Section 6(f) the Purchase Agreement dated as of April 29, 2010 (the “Purchase Agreement”) among J.P. Morgan Securities Inc., as representative (the “Representative”) of the initial purchasers listed on Schedule1 thereto (collectively the “Initial Purchasers”), the Company, SAI and PHI. Capitalized terms used herein and defined in the Purchase Agreement are used as therein defined, unless otherwise defined herein.

          In connection with this opinion, I have examined a copy of: (a) the Indenture executed by the parties thereto; (b) the global note evidencing the Notes (the “Securities”) issued pursuant to the Indenture executed by the Company and the Trustee; (c) the Purchase Agreement executed by the parties thereto, (d) the Pledge Agreement executed by the parties thereto, (e) the Intercreditor Agreement executed by the parties thereto, (f) the Time of Sale Information; (g) the Offering Memorandum; (h) a copy of the organizational documents (“Organizational Documents”) and good standing certificates (the “Good Standing Certificates”) for the Company, SAI, PHI, PFSI, GHP1 and Penson Canada set forth on the Schedule I hereto, (i) Unanimous Written Consent of the Board of Directors of SAI, dated as of April 29, 2010 (the “SAI Resolutions”); and (j) such other documents, records, agreements and certificates as I have deemed appropriate. I have also reviewed such matters of Texas law, Delaware General Corporation Law and Federal law (collectively, “Applicable Law”) as I have considered relevant for the purposes of this opinion. The documents referred to in clauses (a)-(e) are referred to herein at times as the “Transaction Documents.”

          I have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to me as originals, the conformity to the original documents of all documents submitted to me as certified, facsimile, pdf, or photostatic copies, and the authenticity of the originals of all documents submitted to me as copies. I have also assumed that the Transaction Documents have been duly executed by the Trustee and the Representative and delivered by the parties thereto. I have also assumed the accuracy and completeness of representations and warranties of each of the respective Penson Entities set forth in the Transaction Documents and the due performance by each party of its respective obligations under such documents, and that each of the Transaction Documents constitutes a valid and binding obligation of all parties and are enforceable in accordance with their terms against all parties. As to certain factual matters, I have relied, without any independent verification, upon certificates provided by public officials and the representations of the respective Penson Entities set forth in the Transaction Documents together with certificates in support of this opinion dated the date hereof of the Chief Executive Officer of the Company, a Vice Chairman of PFSI, the Executive Vice President of SAI, the President of PHI, a Director of Penson Canada and the Chairman of GHP1 (in its capacity as partner in Penson GHCO). Except as specifically set forth herein, I have not undertaken any search of any filings of any governmental authority or agency or with any court or arbitrator, nor have I undertaken any independent investigation to determine the accuracy of facts material to any such statement or opinion, and no inference as to such statement or opinion should be drawn from the fact of my representation of the Penson Entities.

          In rendering the opinions set forth herein, whenever a statement or opinion herein is qualified by “to my knowledge,” or by words of similar import, it is intended to indicate that, during the course of my representation of the Penson Entities, no information has come to my attention that gives me actual knowledge of the inaccuracy of such statement or opinion. Except as specifically set forth herein, I have not undertaken any independent investigation to determine the accuracy of facts material to any such statement or opinion, and no inference as to such statement or opinion should be drawn from the fact of my representation of the Penson Entities or employment with the Company. In making judgments in respect of matters of materiality, I have relied upon other representatives of the Penson Entities in assessing the possible impact of such items.

          Based upon the foregoing, and subject to the limitations set forth below as well as in the Transaction Documents (and their respective schedules and exhibits), I am of the opinion that:

1)

Each of PFSI, Penson GHCO, Penson Canada, PHI, GHP1 and SAI (each a “Covered Subsidiary” and, collectively, the “Covered Subsidiaries”) has been duly organized and is validly existing and in good standing under the laws of its respective jurisdictions of organization, is duly qualified to do business and is in good standing in each jurisdiction listed opposite its name on Schedule I attached hereto, and has all corporate or general partnership power, as applicable, and authority to own, lease and operate its respective properties and to conduct its businesses as described in the Time of Sale Information and the Offering Memorandum, except where the failure to have such power or authority would not, individually or in the aggregate, have a Material Adverse Effect.

	2)		Each Covered Subsidiary is duly qualified to do business as a foreign corporation in the jurisdictions listed opposite its name on Schedule I attached hereto, with the requisite corporate or general partnership power and authority to own, lease and operate its properties and to conduct its business as described in the Time of Sale Information and the Offering Memorandum, except where the failure to be so qualified or have such power or authority would not, individually or in the aggregate, have a Material Adverse Effect.
	3)		All the outstanding shares of capital stock or other equity interests of each Covered Subsidiary have been duly and validly authorized and issued, and, to the extent permissible as a matter of law, are fully paid and non-assessable.

	6)		The Purchase Agreement has been duly authorized, executed and delivered by SAI.

I have not reviewed the covenants in the any such indentures, agreements or instruments that contain financial ratios or other financial restrictions and no opinion is provided with respect thereto.

the creation, attachment, perfection, priority or enforceability of any security interest.
