The Reporting Persons acquired certain of the shares of Common Stock in connection with a private placement by the Issuer (the “Offering”) which closed on October 22, 2009 (the “Issuance Date”).  In the Offering, the Issuer sold a total of (i) 7,954,543 shares of the Common Stock (collectively, the “Shares”), (ii) warrants to purchase an aggregate of 3,977,270 shares of the Common Stock (the “Warrants”) at an exercise price of $0.88 per share, for a purchase price of $0.125 per share and (iii) rights to purchase an aggregate of up to 5,165,286 shares of the Common Stock (the “Purchase Rights”) at a second closing to occur on May 14, 2010 or such earlier date as the purchasers having agreed to purchase a majority of the shares in such second closing mutually agree upon (the “Second Closing”), at a purchase price of $0.968 per share, for a purchase price of $0.125 per share.

The Warrants were exercisable on the Issuance Date and expire at 5:00 p.m. New York City time on January 7, 2015, subject to the Limitation on Exercise described in Item 5 below.
 
The Purchasing Funds purchased an aggregate of 3,977,272 Shares, 1,988,636 Warrants and 2,582,644 Purchase Rights as follows:

    3,160,131     $ 2,780,915.28       1,580,066     $ 197,508.25       2,052,033     $ 256,504.13

    89,236     $ 78,527.68       44,618     $ 5,577.25       57,946     $ 7,243.25  

Prior to participating in the Offering, the Reporting Persons expended an aggregate of approximately $3,984,745.98 to purchase an aggregate of 2,884,546 shares of Common Stock (the “Previous Holdings”). Such transactions were effected in public offerings and open market purchases and the common stock was acquired in the ordinary course of business.  

The funds used to purchase the Previous Holdings and the Shares, Warrants and Purchase Rights reported in Item 5 below were provided from the available working capital of the entities there indicated.

ITEM 4.                   Purpose of Transactions.
 
The Purchasing Funds acquired the Previous Holdings, Shares, Warrants and Purchase Rights solely for investment. The Reporting Persons expect to review from time to time the investment positions of these entities and may, depending on market and other conditions, increase or decrease their holdings.
 
Whether the entities purchase any additional shares of Common Stock, including by exercise of the Warrants or the Purchase Rights, or dispose of any shares of Common Stock, and the amount and timing of any such transactions, will depend upon the Reporting Persons’ continuing assessments of pertinent factors, including the availability of shares of Common Stock for purchase at particular price levels, the Issuer’s business and prospects, other business investment opportunities, economic conditions, stock market conditions, money market conditions, the attitudes and actions of the board of directors and management of the Issuer, the availability and nature of opportunities to dispose of shares in the Issuer and other plans and requirements of the particular entities. Depending upon their assessments of these factors from time to time, the Reporting Persons may change their present intentions as stated above, including determining to acquire additional shares of Common Stock (by means of open market purchases, privately negotiated purchases, exercise of some or all of the Warrants or Purchase rights, or otherwise) or to dispose of some or all of the shares of Common Stock under their control. At the present time the Reporting Persons do not have any plans or proposals with respect to any extraordinary corporate transaction involving the Issuer or any sale of its assets or any change in its board of directors, management, capitalization, dividend strategy, charter or by-laws, or any other change in its business or corporate structure or with respect to the delisting or deregistration of any of its securities including, without limitation, those matters described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Pursuant to the terms of the Securities Purchase Agreement described in Item 6, Baker has the right to designate a representative (the “Baker Director Designee”) to the board of directors of the Issuer as soon as practicable and no later than December 31, 2009.  The Issuer shall cause the Baker Director Designee to be promptly appointed or elected to the board of directors of the Issuer including, if necessary, by amending its Bylaws to increase the number of authorized directors to enable the Baker Director Designee to be elected or appointed by the board of directors of the Issuer to the vacant seat created thereby.  The Baker Director Designee shall be acceptable to the majority of board of directors of the Issuer, with such acceptance not to be unreasonably withheld.
 
In addition, in the event that the Purchasing Funds purchase no less than all of the Common Stock for which they hold the Purchase Rights described above at the Second Closing, Baker shall have the right to designate an additional representative (the “Second Baker Director Designee”) to the board of directors of the Issuer concurrently with the Second Closing.  The Issuer shall cause the Second Baker Director Designee to be promptly appointed or elected to the board of directors of the Issuer including, if necessary, by securing the resignation of an incumbent director as necessary to enable the Second Baker Director Designee to be elected or appointed by the board of directors of the Issuer to the vacant seat created thereby.  The Second Baker Director Designee shall be acceptable to the majority of the board of directors of the Issuer, with such acceptance not to be unreasonably withheld.
 
Also in connection with the Securities Purchase Agreement, Baker was given certain observer rights and related rights with respect to the board of directors of the Issuer, as described in Item 6 below.

ITEM 5.                   Interest in Securities of the Issuer.

(a) and (b)  Set forth below is the aggregate number of shares of the Common Stock held by the Purchasing Funds, Baker/ Tisch Investments, L.P. and Baker Bros. Investments II, L.P. and beneficially owned by the Reporting Persons, including shares that may be acquired upon the exercise of the Purchase Rights at a purchase price of $0.968 per share, as of the date hereof by each of the following, together with the percentage of outstanding shares of the Common Stock that such number represents based upon (i) 31,376,432 shares of the Common Stock outstanding as reported on the Issuer’s SEC Form 10-Q filed on August 4, 2009 in addition to (ii) 7,954,543 shares of the Common Stock issued on October 22, 2009, pursuant to the Securities Purchase Agreement described in Item 6. Such percentage figures are calculated on the basis that the Purchase Rights held by the Purchasing Funds are deemed exercised into shares of Common Stock but other outstanding derivative securities for the Common Stock are not deemed converted or exercised in shares of the Common Stock.

Registration Rights Agreement

In connection with the Securities Purchase Agreement, on October 22, 2009, the Issuer entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Purchasing Funds and the other parties thereto.

The Issuer agreed to use its best efforts to cause the registration statement to be declared effective by the SEC within 90 days after the initial closing date of October 22, 2009 (or 120 days in the event the registration statement is reviewed by the SEC). If the Issuer fails to meet either of these deadlines, fails to meet filing or effectiveness deadlines with respect to any additional registration statements required by the Registration Rights Agreement or fails to keep any registration statements continuously effective (with limited exceptions), the Issuer may be obligated to pay to the holders of the Shares, Warrants and Purchase Rights liquidated damages in the amount of 1% per month of the purchase price for the Shares, Warrants and Purchase Rights, up to a maximum cap of 8%.

Re:           Board Observation Rights
 
Ladies and Gentlemen:

Pursuant to Section 8.3 of that certain Securities Purchase Agreement by and among A.P. Pharma, Inc. (the “Company”) and the purchasers listed therein, dated October 19, 2009 (the “Purchase Agreement”), the Company hereby agrees as follows:
 
1.           Observation Rights; Board Materials.  The Company covenants and agrees that  Baker Brothers Investments (the “Investor”) may designate a representative (the “Observer”) to be present at all regular, special and telephonic meetings of the Company’s Board of Directors (the “Board”), and that the Company will give the Investor notice of such meetings, by telecopy or by such other means as such notices are delivered to the members of the Board, at the same time notice is provided or delivered to the Board.  Board materials that are sent to the members of the Board in their capacity as such shall be sent to the Observer simultaneously by the Company by means reasonably designed to insure timely receipt by the Observer.  Upon reasonable notice and at a scheduled meeting of the Board or such other time, if any, as the Board may determine in its sole discretion, the Observer may address the Board with respect to the Investor’s concerns regarding significant business issues facing the Company.  The Investor hereby agrees that any non-public proprietary information obtained by the Investor and/or Observer as a result of the Observer’s attendance at Board meetings, or in connection with the Investor’s and/or Observer’s receipt of Board materials, shall be held in confidence and will not be disclosed by the Investor or any affiliates of the Investor or the Observer, except to the extent otherwise required by law.  In addition, the Observer agrees and covenants to be bound by all applicable restrictions placed on the Company’s board of directors, including trading windows and black-out periods relating to the sale of the Company’s securities.
 
Notwithstanding the provisions of the first paragraph of this Section 1, the Company shall be entitled to recuse the Observer from portions of any Board meeting and to redact portions of any Board materials delivered to the Investor and/or the Observer where recusal or redaction is reasonably necessary, in the opinion of counsel to the Company, (i) to preserve attorney-client privilege, (ii) to protect highly confidential information or trade secrets (in each case as determined in good faith by the Board of Directors) or (iii) in the event the Board intends to discuss or vote upon any matter in which the Investor and/or the Observer have a material business or financial interest (other than by reason of the Investor’s and/or the Observer’s interests as a stockholder of the Company).  Further, the members of the Board shall be entitled to hold Executive Sessions (as hereinafter defined) which the Observer may not be invited to attend.  “Executive Sessions” shall mean meetings of the members of the Board in which the Company’s Chief Executive Officer is not present.
 

2.           Termination or Suspension of Rights.  The rights under Section 1 of this letter agreement shall terminate on May 14, 2010 and shall not apply at any time that the Second Baker Director Designee (as defined in the Purchase Agreement) is serving on the Board.  The confidentiality provision hereof will survive any termination of this letter agreement.
 
3.           Counterparts.  This letter agreement may be executed in counterparts and signature pages may be delivered by facsimile, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument.
 
 
   
 
Sincerely,
 
A.P. PHARMA, INC.
