Lender represents and warrants to Borrower ------------------------- that it is acquiring the Note for its own account for investment and not with a view to, or for a sale in connection with, any distribution thereof. 7.9 Assignment. Borrower shall not assign its rights or delegate any of ---------- its duties under any of the Loan Documents without Lender's prior written consent. Lender may freely assign its rights and obligations under the Loan Documents. 7.10 Conversion of Stock. Lender agrees that it will not convert to Common ------------------- Stock any of the shares of Series D Preferred Stock obtained upon conversion of a Note, until lender shall have purchased at least two PET scanners from Borrower pursuant to the terms of that certain Equipment Purchase Agreement dated as of the date hereof. 7.11 Ownership Change Under Section 382 of the Internal Revenue Code; --------------------------------------------------------------------- Special Restrictions Upon Transfer. -------------------------------- 7.11.1 Special Restrictions Upon Transfer. The following ------------------------------------- restrictions shall apply to the transfer of shares of Common Stock, issuable directly or indirectly upon the conversion of any Note. 7.11.2 Definitions. For purposes of this Section 7.11 the ----------- following terms shall have the following meanings: -9- "BOARD" means the Borrower's Board of Directors. "COMMON STOCK" shall mean the Common Stock of Borrower, par value $0.01 per share. "SECTION 382" means Section 382 of the Internal Revenue Code of 1986, as amended, and the regulations thereunder. "SPECIAL BOARD APPROVAL" shall mean the approval by the Board of Directors of Borrower acting in accordance with applicable law. 7.11.3 Purported Transfers Not Effective. Unless such transfer ------------------------------------ shall have been preceded by Special Board Approval, any purported transfer of Common Stock into which any Note is directly or indirectly convertible in excess of the number of shares that can be transferred without increasing the transferee's ownership interest percentage above 4.5% is not effective to transfer ownership of such excess shares (the "Prohibited Shares") from the ----------------- transferor (the "Initial Transferor") to the purported acquiror (the "Purported ------------------ --------- Acquiror"). For this purpose a transferee's ownership interest percentage shall - -------- be calculated pursuant to Section 382. By way of explanation, a transferees ownership interest is generally the sum of the transferee's direct ownership interest percentage as calculated pursuant to Section 382 and the transferee's indirect ownership interest as calculated pursuant to Section 382, with adjustments made to include ownership interests that, under ordinary circumstances, are not included in measuring ownership interests. In the event a Initial Transferor seeks a Special Board Approval, to the extent that the transaction reflected in the proposed request for a Special Board Approval does not result in an "ownership shift" in excess of 40% and does not result in an "ownership change" as those terms are used in Section 382, the approval of the Board will not be unreasonably withheld. Moreover, to the extent that the proceeds of any "ownership shift" of up to 40% results directly or indirectly in the receipt of cash by Borrower, the transaction will be presumed to be in the interest of Borrower unless it results in an "ownership change". 7.11.4 Transfer to Agent of Prohibited Shares; Sale by Agent; ------------------------------------------------------------ Payment of Proceeds. On demand by Borrower (which demand must be made within 30 - ------------------- days of the time Borrower learns of the transfer of Prohibited Shares), a Purported Acquiror must transfer any certificate or other evidence of ownership of the Prohibited Shares within the Purported Acquiror's possession or control, together with any dividends or other distributions that were received by the Purported Acquiror from Borrower with respect to the Prohibited Shares ("Prohibited Distributions"), to an agent designated by Borrower (the "Agent"). ------------------------- ----- The Agent will sell the Prohibited Shares in an arms-length transaction (over a public exchange, if reasonable possible), and the Purported Acquiror will receive an amount of sales proceeds not in excess of the price paid or consideration surrendered by the Purported Acquiror for the Prohibited Shares (or the fair market value of the Prohibited Shares at the time of an attempted transfer to the Purported Acquiror by gift, inheritance, or a similar transfer). If the Purported Acquiror has resold the Prohibited Shares prior to receiving the Borrower's demand to surrender the Prohibited Shares to the Agent, the Purported Acquiror shall be deemed to have sold the Prohibited Shares as agent for the Initial Transferor and shall be required to transfer to the Agent any Prohibited Distributions and the proceeds of such sale, except to the extent that the Agent grants written permission to the Purported Acquiror to retain a portion of such sales proceeds not exceeding the amount that the Purported Acquiror would have received from the Agent if the Agent rather than -10- the Purported Acquiror had resold the Prohibited Shares. If the Initial Transferor can be identified, the Agent will pay to the Initial Transferor any sales proceeds in excess of those due to the Purported Acquiror, together with any amounts received by the Agent from the Purported Acquiror that are attributable to Prohibited Distributions. If the Initial Transferor cannot be identified within 90 days, the Agent may pay any amounts due to the Initial Transferor into a court or governmental agency, if applicable law permits, and otherwise must transfer such amounts to a charity designated by Borrower. In no event shall amounts due to the Initial Transferor pursuant to Article inure to the benefit of Borrower or the Agent, but such amounts may be used to cover expenses incurred by Agent in attempting to identify the initial Transferor. If the Purported Acquiror fails to surrender the Prohibited Shares within the next 30 business days from demand by Borrower, then the Borrower will institute legal proceedings to compel the surrender. 7.11.5 Legend. Lender understands and agrees that each certificate ------ held by Lender representing a Note, and Series D Preferred Stock and Common Stock issuable upon conversion thereof, or any other securities issued in respect of a Note, and Series D Preferred Stock and Common Stock issuable upon conversion thereof upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall bear the following legend (in addition to any legend required by this Agreement, the other Agreements or under applicable federal or state securities laws): "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE RESTRICTED BY THE TERMS OF, AND ARE SUBJECT TO RESTRICTIONS ON TRANSFER AND RIGHTS OF SALE AS PROVIDED IN A LOAN AGREEMENT BETWEEN THE COMPANY AND THE HOLDER HEREOF, OR ITS SUCCESSOR, A COPY OF WHICH IS AVAILABLE FROM THE COMPANY."

Pursuant to that certain Statement of Designation Establishing Series D Preferred Stock of Positron Corporation filed with the Texas Secretary of State on May 21, 2004, the Series D Preferred Stock is junior to the Borrower's Series A Preferred Stock and Series C Preferred Stock, both as to dividends and as to distributions of assets upon liquidation or winding up of the Borrower. 1 SCHEDULE 3.5 Governmental Consent. - -------------------- In connection with the transactions contemplated by the Agreement, the Borrower filed a Statement of Designation Establishing Series D Preferred Stock of Positron Corporation with the Texas Secretary of State on May 21, 2004 and will file (i) a registration statement on an applicable form to register the shares of Series D Preferred Stock (and Common Stock issuable upon conversation thereof) issuable upon conversion of the Note, (ii) a proxy statement on Schedule 14A to approve an amendment to its Articles of Incorporation to increase the number of its authorized shares of Common Stock, and (iii) appropriate UCC-1 financing statements with applicable jurisdictions pursuant to the Security Agreement. 2 SCHEDULE 3.8 Litigation. - ---------- The Company received a warning letter ("Warning Letter") dated April 26, 2004 from the Department of Health and Human Services regarding various alleged deficiencies under the Current Good Manufacturing Practice requirements of the Quality System regulations for medical devices, a copy of which has been provided to Investor. The Borrower is subject to the following legal proceedings: PROFUTURES CAPITAL BRIDGE FUND, L.P. On September 26, 2000, ProFutures Bridge Capital Fund, L.P. ("ProFutures") filed a complaint against the Borrower in Colorado state court for declaratory relief and breach of contract (the "Complaint"). The Complaint alleged that the Borrower breached four stock purchase warrants issued to ProFutures on the basis that the Borrower failed to notify ProFutures of dilutive events and failed to register the full number of shares ProFutures was allegedly entitled to purchase under the warrants when, on February 14, 2000, the Borrower registered 1,500,000 shares of stock underlying ProFutures' warrants instead of 4,867,571. The Complaint further alleged that the Borrower's issuance of shares of common stock to Imatron, Inc. on or about January 22, 1999, (the "Imatron Transaction") was a dilutive event pursuant to the anti-dilution provisions contained in the four stock purchase warrants. The Complaint sought declarations that the consideration received by the Borrower in the Imatron Transaction increased the number of shares issuable under the warrants, the Borrower breached the warrants by failing to notify ProFutures of the Imatron Transaction and its effect on ProFutures' warrants at the time of the Imatron Transaction and that the Borrower further breached the warrants by failing to register the number of shares ProFutures alleged were purchasable under its warrants. The Complaint sought an unspecified amount of monetary damages. The Colorado State level case of ProFutures v. Positron, District Court, City and County of Denver, Colorado, Case No. 00CV7146, was tried before the Court in June 2002. The Court issued its Findings of Fact, Conclusions of Law and Judgment on November 13, 2002. The Court agreed with the Borrower's determination of the value of the consideration paid for the shares issued to Imatron and that there was no evidence of fraud by the Borrower. The Court agreed with ProFutures that the Borrower breached the 1996 stock purchase warrant with ProFutures by failing to give ProFutures written notice stating the adjusted exercise price and the new number of shares deliverable as a result of the Imatron Transaction and by failing to register the shares to which ProFutures was entitled under the warrant as a result of the Imatron Transaction. Nevertheless, the Court also found that ProFutures' alleged damages were uncertain and speculative and that ProFutures was not entitled to recover actual damages. Therefore ProFutures was awarded $1 in nominal damages. ProFutures has appealed the trial Court's findings and the Borrower has cross-appealed. Those appeals are presently pending before the Court of Appeals, State of Colorado. In the federal case of ProFutures v. Positron, et al., United States District Court for the District of Colorado, Case No. 02-N-0154, the Complaint alleged two causes of action against the Borrower: fraudulent transfer and injunctive relief. The allegations arose out of a June 2001 loan agreement between the Borrower and Imatron. The action was dismissed in 2002 without prejudice. 3 SCHEDULE 3.8 CONTINUED 10P10, L.P. In December 2001, 10P10, L.P., the Borrower's previous landlord for its premises located at 16350 Park Ten Place, Suite 150, Houston, Texas, filed a complaint (Cause No. 2001-65534 in the 165th Judicial District Court of Harris County, Texas) against the Borrower alleging breach of lease agreement. The Borrower disputes the amount of lease commissions and construction costs charged by 10P10, L.P. in conjunction with the subleasing of the premises. Although 10P10, L.P. asserted a claim in excess of $150,000, a subsequent analysis of the transactions under the lease has resulted in the reduction of the lease obligation alleged by 10P10, L.P. to approximately $97,000. Although the Borrower disputes the amount of the claim, due to the pending lawsuit, approximately $97,000 is recorded as an accrued liability as of December 31, 2003. The case is set for trial on a two week docket beginning in September 2004. RADIOLOGY CORPORATION OF AMERICA, INC. A judgment in the amount of $75,000 has been entered against the Borrower in Texas state court in favor of Radiology Corporation of America, Inc., a vendor to the Borrower. In satisfaction of the judgment the Borrower and the creditor have agreed that the judgment may be satisfied by five monthly payments of $15,000 each commencing March 10, 2004. 4 SCHEDULE 3.9 Compliance with Laws and Agreements. - ----------------------------------- See Warning Letter on Schedule 3.8. 5 SCHEDULE 3.10 Taxes. - ----- The following taxes are due and payable: Sales Tax: New York $94,881.78 Florida $7,875.00 Alabama $31,250.00 Texas $2,894.81 Property Tax: $321,884.17 6 EXHIBIT A --------- NOTE -1- EXHIBIT B --------- SECURITY AGREEMENT -1-
