4. Effect of the Merger on the Capital Stock of the Constituent Corporations; Exchange of Certificates.

(a) Effect on Capital Stock. As of the Effective Time of the Merger, by virtue of the Merger and without any action on the part of the holder of any shares of Target Common Stock:

(i) Capital Stock of Sub. Each issued and outstanding share of capital stock of Sub shall be converted into and become one fully paid and non-assessable share of Target Common Stock. Each stock certificate of Sub evidencing ownership of any such shares shall continue to evidence ownership of such shares of capital stock of the Surviving Corporation.

(ii) Cancellation of Treasury Stock. All shares of Target Common Stock that are owned by Target (as treasury stock), Acquiror or Sub shall be canceled and retired and shall cease to exist and no consideration shall be delivered in exchange therefor.

(iii) Conversion of Target Common Stock. The issued and outstanding shares of Target capital stock (other than shares to be canceled pursuant to Section 4(a)(ii) hereof and shares, if any, held by persons exercising dissenters’ rights in accordance with Section 1300 of the CGCL) held by a holder of record of Target capital stock immediately prior to the Effective Time shall be converted, without any action on the part of such holder, into the right to receive a number of whole shares of Class A common stock of Acquiror, $.01 par value (“Acquiror Common Stock”), determined by multiplying the number of shares of Target capital

-3-

stock held by such holder of Target capital stock by a fraction (the “Exchange Ratio”), the numerator of which is $6.50, and the denominator of which is the initial public offering price per share of Class A common stock of the Acquiror in connection with its initial public offering (the “Merger Consideration”) and rounding the product up for any fraction equal to or greater than one half, and rounding the product down for any fraction that is less than one half. The initial public offering price per share of Class A common stock of the Acquiror shall be determined by reference to the per share amount appearing under the column “Price to Public” on the cover page of the Acquiror’s prospectus, dated October 28, 2004, regarding the offering of 29,000,000 shares of Class A common stock of the Acquiror, without any deduction for underwriting discounts and commissions.

(iv) Conversion of Target Options. As of the Effective Time, each outstanding option to purchase shares of Target Common Stock granted pursuant to the PDI Inc. 1996 Equity Incentive Plan and the PDI Inc. 1998 Stock Plan (the “Target Stock Option Plans”), whether vested or unvested (a “Target Option”), will be converted into an option to purchase shares of Acquiror Common Stock (each, an “Acquiror Option”). In addition, the Target Stock Option Plans shall be terminated by resolution of the Target’s board of directors. Except as provided below, each such Target Option converted by Acquiror under this Agreement shall retain its respective vesting schedule as set forth under the applicable Target Stock Option Plan; however, the converted Target Options will be governed by the 2004 Omnibus Incentive Compensation Plan as of the Effective Time. The 2004 Omnibus Incentive Compensation Plan shall provide for terms and conditions such that the converted Target Options shall continue to be subject to the same terms and conditions that are comparable to those set forth in the applicable Target Stock Option Plan, except that (i) each such option will be exercisable for that number of whole shares of Acquiror Common Stock obtained by multiplying the number of shares of Target Common Stock that would be issuable upon exercise of such option immediately prior to the Effective Time, assuming that all vesting conditions applicable to such option were then satisfied, by the Exchange Ratio and rounded down to the nearest whole number of shares of Acquiror Common Stock, and (ii) the per share exercise price for the shares of Acquiror Common Stock issuable upon exercise of such converted Target Option will be equal to the quotient determined by dividing the exercise price per share of Target Common Stock at which such option was exercisable immediately prior to the Effective Time by the Exchange Ratio, rounded up to the nearest cent. Consistent with the terms of the Target Stock Option Plans and the documents governing the outstanding Target Options under such plans, the Merger will not terminate any of the outstanding Target Options under the Target Stock Option Plans or accelerate the exercisability or vesting of such options or the shares of Target Common Stock which will be subject to those options upon the conversion of the Target Options in connection with the Merger. It is the intention of the parties that the Target Options converted to Acquiror Options qualify, to the maximum extent permissible, following the Effective Time, as incentive stock options, as defined in Section 422 of the Code, to the extent, and only to the extent, the Target Options so converted qualified as incentive stock options prior to the Effective Time.

(iv) Dissenters’ Rights. If any holder of Target Common Stock (a “Dissenting Holder”) duly demands purchase of his, her or its shares of Target Common Stock in connection with the Merger under Chapter 13 of the CGCL (such shares being “Dissenting

-4-

Shares”), the Dissenting Shares shall not be converted into Merger Consideration but shall be converted into the right to receive an amount in cash equal to the fair market value of such shares as may be determined to be due with respect to such Dissenting Shares pursuant to the law of the State of California. After the Effective Time of the Merger, Acquiror shall issue and deliver to any holder of shares of Target Common Stock who shall have withdrawn his, her or its demand for purchase or have failed to perfect or shall have otherwise lost his, her or its right of purchase, in any case pursuant to the CGCL, upon surrender by such Dissenting Shareholder of his, her or its, certificate or certificates representing shares of Target Common Stock, the Merger Consideration to which such Dissenting Shareholder is then entitled under Section 4(a)(iii) of this Agreement.

(b) Exchange of Certificates.

(i) Exchange Agent. Prior to the Closing Date, Acquiror shall appoint The Bank of New York to act as Exchange Agent (the “Exchange Agent”) in the Merger.

(ii) Exchange Procedures. At the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate (i) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the certificates held by such person shall pass, only upon proper delivery of the certificates to the Exchange Agent and shall be in a form and have such other provisions as Acquiror may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the applicable Merger Consideration. Upon surrender of a certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such certificate shall be entitled to receive in exchange therefor the Merger Consideration with respect to such shares, without interest and the certificate so surrendered shall forthwith be canceled.

(iii) No Further Ownership Rights in Target Common Stock. All Merger Consideration delivered upon the surrender of certificates that represented shares of Target Common Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Target Common Stock theretofore represented by such certificates. At the close of business on the day on which the Effective Time occurs the stock transfer books of Target shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Target capital stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, certificates are presented to the Surviving Corporation or the Exchange Agent for transfer or any other reason, they shall be canceled and exchanged as provided in this Section 4.

5. TERMINATION

(a) Termination by Mutual Agreement. Notwithstanding the approval of this Agreement by the shareholders of Target, this Agreement may be terminated at any time prior to the Effective Time of the Merger by mutual written consent of the Constituent Corporations.

(b) Effects of Termination. In the event of the termination of this Agreement, this Agreement shall become void and there shall be no liability on the part of either Target or Sub or their respective officers or directors.

6. GENERAL PROVISIONS.

(a) Amendment. This Agreement may be amended by the boards of directors of the Constituent Corporations and the Acquiror hereto any time prior to the effective time of the Merger; however, after approval hereof by the shareholders of the Constituent Corporations, no amendment shall be made which by law requires the further approval of such shareholders without obtaining such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

(b) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.

(c) Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of New York, without giving effect to its principles governing conflicts of laws, except to the extent the laws of California or Delaware are mandatorily applicable to the Merger.

(d) Entire Agreement. This Agreement constitutes the entire agreement among such parties pertaining to the subject matter hereof and thereof, and the agreements contemplated hereby and all negotiations and drafts of the parties with regard to the transactions contemplated herein, and any and all written or oral agreements existing between the parties hereto regarding such transactions are expressly canceled.
