Section 1350, As Adopted Pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 2 Independent Auditors' Report To the Plan Administrator of Cytogen Retirement Savings Plan: We have audited the accompanying statements of net assets available for plan benefits of Cytogen Retirement Savings Plan (the Plan) as of December 31, 2002 and 2001, and the related statement of changes in net assets available for plan benefits for the year ended December 31, 2002. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan as of December 31, 2002 and 2001, and the changes in net assets available for plan benefits of the Plan for the year ended December 31, 2002, in conformity with accounting principles generally accepted in the United States of America. Our audit was performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ KPMG LLP ------------ Princeton, New Jersey June 23, 2003 3 CYTOGEN RETIREMENT SAVINGS PLAN Statements of Net Assets Available for Plan Benefits December 31, 2002 and 2001 2002 2001 ------------ ------------ Assets: Investments $ 3,699,908 $ 5,266,813 Participant contributions receivable 13,044 16,990 Employer contributions receivable 18,612 47,510 Interest receivable 61 - Participant loans 34,066 - ------------ ------------ Net assets available for plan benefits $ 3,765,691 $ 5,331,313 ============ ============ See accompanying notes to financial statements. 4 CYTOGEN RETIREMENT SAVINGS PLAN Statement of Changes in Net Assets Available for Plan Benefits Year Ended December 31, 2002 Net assets available for plan benefits, beginning of year $ 5,331,313 Additions: Investment income: Dividend income from investments 89,599 Interest income from loans 586 Other income 118 ----------- 90,303 ----------- Contributions: Participants 366,478 Employer 97,768 Rollovers 705 ----------- 464,951 ----------- Total additions 555,254 ----------- Deductions: Net depreciation in fair value of investments 1,017,153 Benefits paid to participants 1,099,850 Plan expenses 3,873 ----------- Total deductions 2,120,876 ----------- Net decrease (1,565,622) ----------- Net assets available for plan benefits, end of year $ 3,765,691 =========== See accompanying notes to financial statements. 5 CYTOGEN RETIREMENT SAVINGS PLAN Notes to Financial Statements December 31, 2002 and 2001 (1) Description of the Plan (a) Organization The Cytogen Retirement Savings Plan (the Plan) is a defined contribution plan for the employees of Cytogen Corporation (the Employer or the Company) that was established on December 15, 1986. The Plan is governed by the provisions of the Employee Retirement Income Security Act of 1974 (ERISA), as amended, and is intended to comply with Sections 401(a) and 401(k) of the Internal Revenue Code. The following description of the Plan provides only general information. Participants should refer to the Plan document for a more complete description of the Plan's provisions. (b) Eligibility Each employee becomes eligible to participate in the Plan as of the date when the employee attains the age of 21 years and has completed six months of service. (c) Administration The Employer designates a person or persons to serve as administrator under the Plan, who performs all such duties as are necessary to operate, administer, and manage the Plan. The expenses necessary to administer the Plan are generally borne by the Employer, including necessary professional assistance. (d) Contributions Beginning January 1, 2002, each active participant may enter into a written salary deferral agreement with the Employer in which the employee may elect to defer an amount of up to 75% of his or her compensation, subject to the maximum contribution level set by the Internal Revenue Code. If the participant is age 50 or older during the calendar year and makes the maximum allowable pre-tax contribution to the Plan, the participant is entitled to make an additional "catch-up contribution" up to the maximum allowable pre-tax contribution. The Employer, at its discretion, may make a matching contribution in an amount up to 50% of the employee contribution, not to exceed limitations set forth by the Plan. The Employer may also make an annual Employer discretionary contribution under the Plan in an amount that the Employer's Board of Directors shall determine by resolution. The allocation of this discretionary contribution shall be made in the proportion that the compensation paid to each participant during the Plan year bears to the compensation paid to all such participants, subject to limitations set forth by the Plan. The Employer has the ability to make discretionary or matching contribution in cash or Cytogen common stock. The Plan also permits the rollover of cash transferred from other employee benefit plans which are qualified under the Internal Revenue Code. Rollovers of cash are included as part of asset additions in the statement of changes in net assets available for plan benefits. For the year ended December 31, 2002, rollovers of cash amounted to $705. 6 CYTOGEN RETIREMENT SAVINGS PLAN Notes to Financial Statements December 31, 2002 and 2001 (e) Vesting and Forfeitures A participant's interest in the Employer matching or discretionary contribution vests over four years of service, at which time it becomes 100% vested. Vesting credit shall be given for each year of service, except plan years during which a participant did not complete at least 1,000 hours of service. If a participant terminates employment and is not 100% vested, the nonvested portion of the participant's account shall be placed in a separate account and will become a forfeiture upon the date such terminated participant incurs a one-year break in service. These forfeitures shall be used by the Employer to reduce the Employer's contribution or to pay plan expenses. Forfeitures used during 2002 were $47,639. (f) Distributions/Benefits A participant who attains the normal retirement age shall have a vesting percentage of 100%. If a participant retires from the active service of the Employer on or after the normal retirement date, then he or she is entitled to receive a distribution of the entire value of his or her vested participant account, or may elect to an annuity distribution as permited under the Plan. A participant who retires from the service of the Employer on account of disability shall have a vesting percentage of 100% and is entitled to receive a distribution of the entire value of their participant account. (g) Participant Loans All participants in the Plan may obtain, under certain conditions, a loan secured by the participant's account balance. The amount of all outstanding loans to a participant may not exceed the lesser of 50% of the participant's vested account balance or $50,000. The loans are made at a rate equivalent to rates charged by a professional lender in similar circumstances. Loans are repaid in no more than five years, except if the loan is for the purchase of the participant's primary residence, in which case the repayment period may exceed five years.

Investments are stated at market value. (b) Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the financial statements and the related disclosures during the reporting period. Actual results could differ from those estimates. (c) Valuation of Investments Investments represent units in a series of funds managed by the investment manager. The Plan's investment funds are stated at market value, as determined based on market quotes of the underlying assets. (d) Plan Expenses All administrative costs associated with the operation of the Plan are generally paid by the Employer in accordance with the terms of the Plan. (e) Purchases and Sales of Securities Purchases and sales of securities are recorded on a trade date basis. 9 CYTOGEN RETIREMENT SAVINGS PLAN Notes to Financial Statements December 31, 2002 and 2001 (3) Investments The following table presents the current values of individual assets that represent 5% or more of the Plan's net assets available for plan benefits as of December 31, 2002 and 2001 as follows: Description?Issuer of Investment 2002 2001 -------------------------------------------- ----------- ----------- Merrill Lynch Fundamentaal Growth Fund, Inc. $ 568,680 $ - Federated Capital Appreciation Fund 594,925 - Merrill Lynch U.S. Government Mortgage Fund 472,823 - Merrill Lynch Retirement Preservation Trust 1,513,160 - MFS Emerging Growth Fund - 433,869 Massachusetts Investor Trust - 324,116 Massachusetts Investor Growth Stock Fund - 1,096,579 MFS Research Fund - 384,914 MFS Capital Opportunities Fund - 577,702 MFS Government Securities Fund - 667,617 MFS Global Equity Fund - 349,929 MFS Fixed Fund - 877,372 (4) Tax Status The trust established under the Plan is qualified under the Internal Revenue Code as exempt from federal income taxes.
