The Common Stock was acquired in the ordinary course of the Funds’ business and is held by each of the Funds in separate accounts maintained for each of the Funds at the Funds’ prime broker. While the Funds’ agreement with their prime broker permits the prime broker to extend margin credit to the Funds as and when required to open or carry positions in the accounts, subject to applicable federal margin regulations, stock exchange rules and the prime broker’s credit policies, the Funds did not purchase any of the shares of Common Stock on margin.

The reporting persons are filing this Schedule 13D in accordance with Rule 13d-1(f) under the Securities Exchange Act of 1934, as amended. The reporting persons may in the future, subject to the terms of the agreement described in Item 6 of this Schedule 13D, determine to purchase more Common Stock and/or dispose of Common Stock in the ordinary course of their investment activities, as market and other conditions dictate. However, in connection with the agreement described in Item 6 of this Schedule 13D, the filing persons may from time to time be provided with information by the issuer and may convey to the issuer their views or opinions with regard to the matters set forth therein.

Item 6.	Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
	On February 4, 2008, the filing persons entered into an agreement (the “February 4th Agreement”) with the issuer pursuant to which, in connection with discussions that the filing persons had requested with the issuer, the filing persons agreed to treat as confidential certain information concerning the issuer that may be provided to the filing persons no later than July 31, 2008, to use it solely for the purpose of evaluating the filing persons’ investment in the issuer, and not to disclose it without the prior written consent of the issuer or as may be required by applicable laws, rules and/or regulations. Pursuant to the February 4th Agreement, the filing persons also agreed not to: (a) acquire, offer to acquire, or agree to acquire, directly or indirectly, any voting securities or direct or indirect rights to acquire any voting securities of the issuer, any subsidiary, successor to or person in control thereof, or any assets of the issuer or any subsidiary, division of the issuer or of any such successor or controlling person thereof; (b) make or participate in any solicitation of proxies to vote, or seek to advise or influence any person or entity with respect to the voting of any voting securities of the issuer; (c) make any public announcement with respect to, or submit a proposal for or offer of any extraordinary transaction involving the issuer or any of its securities or assets; (d) form, join or in any way participate in a "group" as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (other than a group comprised solely of the filing persons), in connection with any of the foregoing; (e) amend its stated purpose, as set forth in Item 4 of its Schedule 13D/A filed on January 22, 2008, or otherwise act or seek to control or influence the management, Board of Directors or policies of the issuer (which shall not, however, prohibit confidential communication to management of the filing persons’ views and opinions); (f) take any action that could reasonably be expected to require the issuer to make a public announcement regarding the possibility of any of the foregoing events; or (g) request that the issuer or any of its representatives amend or waive any of the foregoing provisions (b) through (e) (the “Standstill Clause”). The February 4th Agreement expired on July 31, 2008. On August 25, 2008, the filing persons entered into an agreement (the “August 25th Agreement”) with the issuer on substantially the same terms and conditions as the February 4th Agreement, except that the August 25th Agreement did not contain the Standstill Clause. On March 15, 2009, the filing persons entered into an agreement (the “March 15th Agreement”) with the issuer on substantially the same terms and conditions as the August 25th Agreement, except for the addition of a termination clause. Notwithstanding the foregoing, and as set forth in Item 4, above, the reporting persons continue to hold the Common Stock for investment in the ordinary course of their investment activities and have not acquired the Common Stock with any purpose of, or with the effect of, acquiring, changing or influencing the control of the issuer, or in connection with or as a participant in any transaction having that purpose or effect. The foregoing description of the March 15th Agreement is not intended to be complete and is qualified in its entirety by reference to the copy of the agreement filed herewith as Exhibit B and incorporated by reference herein.

Attention: Lawrence A. Oberman,

Douglas Granat and Steven G. Simon

Gentlemen:

In connection with discussions (the “Communications”) that you have requested to have with Scientific Learning Corporation, a Delaware corporation (the “Company”), the Company expects to make available to you certain information concerning the Company beginning on or after the date of this letter and ending no later than when this agreement is terminated. . This letter replaces and supersedes the letter agreement between you and the Company dated August 25, 2008 which, according to its terms, expires today. As a condition to such information being furnished to you and your directors, officers, employees, agents, advisors and affiliates (including, without limitation, attorneys, accountants, consultants and financial advisors) (collectively, “Representatives”), you agree to treat any information concerning the Company (whether prepared by the Company, its advisors or otherwise and irrespective of the form of communication) which is furnished hereunder to you or to your Representatives now or in the future by or on behalf of the Company (herein collectively referred to as the “Protected Material”) in accordance with the provisions of this letter agreement, and to take or abstain from taking certain other actions hereinafter set forth.

1. Protected Material. The term “Protected Material” also shall be deemed to include all notes, analyses, compilations, studies, interpretations or other documents prepared by you or your Representatives which contain, reflect or are based upon, in whole or in part, the information furnished to you or your Representatives pursuant hereto which is not available to the general public. The term “Protected Material” does not include information which (i) is or becomes generally available to the public other than as a result of a breach of this Agreement by you or your Representatives, (ii) was within your possession prior to its being furnished to you by or on behalf of the Company, provided that the source of such information was not known by you to be bound by a confidentiality agreement with or other contractual, legal or fiduciary obligation of confidentiality to the Company, (iii) is or becomes available to you on a non- confidential basis from a source other than the Company provided that such source was not known by you to be bound by a confidentiality agreement with or other contractual, legal or fiduciary obligation of confidentiality to the Company or any other party with respect to such

information, (iv) is disclosed by the Company to a third party without a duty of confidentiality, (v) is disclosed under operation of law in accordance with Section 3 or 4 below, or (vi) is disclosed by you or your Representatives with the Company’s prior written approval.

2. Purpose and Use of Protected Material. You agree that you and your Representatives shall use the Protected Material solely for the purpose of evaluating your investment in the Company, and that the Protected Material will be kept confidential, and you and your Representatives will not disclose or use for purposes other than evaluating your investment in the Company any of the Protected Material in any manner whatsoever.

3. Non-Disclosure. In addition, you agree that, without the prior written consent of the Company, neither you nor your Representatives will disclose to any other person the fact that any Protected Material has been made available hereunder; provided, that you may make such disclosure if in the opinion of your counsel, such disclosure is necessary to avoid committing a violation of law. In such event, you shall use your best efforts to give the Company advance notice of such disclosure.

4. Required Disclosure. In the event that you or your Representatives are requested or required (by oral questions, interrogatories, requests for information or documents in legal proceedings, subpoena, civil investigative demand or other similar process) to disclose any of the Protected Material, you shall provide the Company with prompt notice of any such request or requirement so that the Company may seek a protective order or other appropriate remedy and/or waive compliance with the provisions of this letter agreement. If, in the absence of a protective order or other remedy or the receipt of a waiver by the Company, you or any of your Representatives are nonetheless, in the opinion of counsel legally compelled to disclose the Protected Material to any tribunal, you or your Representative may, without liability hereunder, disclose to such tribunal only that portion of the Protected Material which such counsel advises is legally required to be disclosed, provided that you exercise your reasonable efforts to preserve the confidentiality of the Protected Material, including, without limitation, by cooperating with the Company to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Protected Material by such tribunal.

5. No Representation of Accuracy. You understand and acknowledge that neither the Company nor any of its representatives makes any representation or warranty, express or implied, as to the accuracy or completeness of the Protected Material made available to you. You agree that neither the Company nor any of its Representatives shall have any liability to you or to any of your Representatives relating to or resulting from the use of or reliance upon such Protected Material or any errors therein or omissions therefrom.

6. No Legal Obligation. You agree that the Company is not bound under any legal obligation of any kind whatsoever with respect to you by virtue of this letter agreement except for the matters specifically agreed to herein. You further acknowledge and agree that the Company reserves the right, in its sole discretion, to provide or not provide Protected Material to you or your Representatives under this letter agreement and to terminate Communications at any time.

7. Waiver. It is understood and agreed that no failure or delay by the Company in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or future exercise thereof or the exercise of any other right, power or privilege hereunder.

8. Securities Laws. You acknowledge and agree that you are aware (and that your Representatives are aware or, upon receipt of any Protected Material, will be advised by you) of the restrictions imposed by the United States federal securities laws on a person possessing material non-public information about a public company and that you and your Representatives will comply with such laws.

9. Miscellaneous. You agree to be responsible for any breach of this agreement by any of your Representatives. In case any provision of this agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions of the agreement shall not in any way be affected or impaired thereby.

10. Injunctive Relief. It is further understood and agreed that money damages would not be a sufficient remedy for any breach of this letter agreement by you or any of your Representatives and that the Company shall be entitled to equitable relief, including injunction and specific performance, as a remedy for any such breach. Such remedies shall not be deemed to be the exclusive remedies for a breach of this letter agreement but shall be in addition to all other remedies available at law or equity. In the event of litigation relating to this letter agreement, if a court of competent jurisdiction determines that you or any of your Representatives have breached this letter agreement, then you shall be liable and pay to the Company the reasonable legal fees incurred in connection with such litigation, including an appeal therefrom.

11. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California applicable to agreements made and to be performed within such State.

12. Term; Termination. Information may be provided under this Agreement until the Agreement is terminated. Either party may terminate this Agreement prior to its expiration by giving 5 days prior written notice to the other party, but the obligations of this Agreement will continue with respect to information disclosed prior to the effective date of the termination. You acknowledge that information disclosed under this Agreement prior to termination may continue to constitute material non-public information about a public company after termination, and you agree that after termination, you and your Representatives will continue to comply with the restrictions imposed by the United States federal securities laws on persons possessing such information.

(Remainder of page intentionally left blank)

Please confirm your agreement with the foregoing by signing and returning one copy of this letter to the undersigned, whereupon this letter agreement shall become a binding agreement between you and the Company.

		Very truly yours,
