Neither Parent, the Company nor the Stockholder will issue any press release or make any other public statement, and shall not authorize or permit any of its Subsidiaries or Affiliates or any of its or their Representatives to issue any press release or make any other public statement with respect to the Merger Agreement, this Agreement, the Registration Rights Agreement or any of the transactions contemplated by the Merger Agreement, this Agreement or the Registration Rights Agreement without the prior written consent of the other parties hereto (such consent not to be unreasonably withheld, conditioned or delayed), except as may be required by Law or by any listing requirement with the Nasdaq or the Toronto Stock Exchange, including any filings required under the Securities Act or the Exchange Act.

The Stockholder has approved the Certificate of Amendment. The Stockholder hereby waives its right of first offer under the Amended and Restated Preferred Stock Purchase Agreement, dated as of November 26, 2003, by and between the Company and the Stockholder, in connection with the Merger Agreement and the transactions contemplated thereby.

ARTICLE VI

MISCELLANEOUS

6.1. Termination. This Agreement shall remain in effect until the earliest to occur of (i) the termination of the Merger Agreement in accordance with its terms, and (ii) the delivery of written notice of termination by the Stockholder to Parent following any Fundamental Amendment effected without the prior written consent of the Stockholder, and upon the occurrence of the earliest of such events this Agreement shall terminate and be of no further force; provided, however, that the provisions of Section 5.6, this Section 6.1, the last sentence of Section 6.2(a) and Sections 6.4 through 6.13 shall survive any termination of this Agreement. Nothing in this Section 6.1 and no termination of this Agreement shall relieve or otherwise limit any party of liability for willful breach of this Agreement. “Fundamental Amendment” means

the execution by the Company, Parent, US Corp. and Merger Sub of an amendment to, or waiver by the Company, Parent, US Corp. or Merger Sub of any provision of, the Offer or the Merger Agreement that reduces the amount of the Offer Price or the Merger Consideration, changes the form of the Offer Price or the Merger Consideration to include or substitute therefor a form other than cash and Parent Common Stock, or decreases the ratio of cash to Parent Common Stock included in the Offer Price or the Merger Consideration. If the Stockholder does not exercise the termination right described above within five business days following the date the Stockholder is notified that such Fundamental Amendment is effected, then this Agreement shall give effect to any modified terms incorporated from the Merger Agreement and, except as so modified, shall continue in full force and effect.

6.2. Legends; Stop Transfer Order.

(a) In furtherance of this Agreement, the Stockholder hereby authorizes and instructs the Company to instruct its transfer agent to enter a stop transfer order with respect to all of the Covered Shares held of record by the Stockholder and to legend the share certificates. The Company agrees that as promptly as practicable after the date of this Agreement it shall give such stop transfer instructions to the transfer agent for the Company Stock and to legend the share certificates. The Company agrees that, (i) if this Agreement is terminated in accordance with Section 6.1, then, promptly following the termination of this Agreement, (ii) if Merger Sub accepts the Covered Shares for payment pursuant to the terms of the Offer, then, concurrently with such acceptance (and in any event within such time as would not delay receipt by the Stockholder of the Offer Price), or (iii) if the transactions contemplated by the Merger Agreement are effected as a One Step Merger, then, immediately following the Closing (and in any event within such time as would not delay receipt by the Stockholder of the Merger Consideration), the Company will cause any stop transfer instructions imposed pursuant to this Section 6.2 to be lifted and any legended certificates delivered pursuant to this Section 6.2 to be replaced with certificates not bearing such legend.

(b) Each certificate representing Covered Shares held of record by the Stockholder shall bear the following legend on the face thereof:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON VOTING, TRANSFER AND CERTAIN OTHER LIMITATIONS SET FORTH IN THAT CERTAIN STOCKHOLDER AGREEMENT DATED AS OF FEBRUARY 25, 2008, AMONG SXC HEALTH SOLUTIONS CORP., NEW MOUNTAIN AFFILIATED INVESTORS, L.P. AND NATIONAL MEDICAL HEALTH CARD SYSTEMS, INC., AS THE SAME MAY BE AMENDED FROM TIME TO TIME, COPIES OF WHICH STOCKHOLDER AGREEMENT ARE ON FILE AT THE PRINCIPAL OFFICE OF NATIONAL MEDICAL HEALTH CARD SYSTEMS, INC.”

The Stockholder will cause all of its Existing Shares held of record by the Stockholder and any securities that become Covered Shares held of record by the Stockholder after the date hereof to be delivered to the Company for the purpose of applying such legend (if not so endorsed upon issuance). The Company shall return to the delivering party, as promptly as possible, any securities so delivered. The delivery of such securities by the delivering party shall not in any way affect such party’s rights with respect to such securities.

6.3. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to any Covered Shares, except as otherwise provided herein. All rights, ownership and economic benefits of and relating to the Covered Shares shall remain vested in and belong to the Stockholder, and Parent shall have no authority to direct the Stockholder in the voting or disposition of any of the Covered Shares, except as otherwise provided herein.

6.4. Notices.

(a) All notices and other communications hereunder shall be in writing and shall be deemed given if delivered personally, by facsimile (upon telephonic confirmation of receipt), on the first business day following the date of dispatch if delivered by a recognized next day courier service or on the third business day following the date of mailing if delivered by registered or certified mail, return receipt requested, post prepaid.

6.5. Interpretation. The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement, and Section references are to this Agreement unless otherwise specified. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The meanings given to terms defined herein shall be equally applicable to both the singular and plural forms of such terms. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. This Agreement is the product of negotiation by the parties having the assistance of counsel and other advisers. It is the intention of the parties that this Agreement not be construed more strictly with regard to one party than with regard to the others.

6.6. Counterparts. This Agreement may be executed by facsimile and in counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

6.7. Entire Agreement. This Agreement, the Registration Rights Agreement and, to the extent referenced herein, the Merger Agreement, together with the several agreements and other documents and instruments referred to herein or therein or annexed hereto or thereto,

embody the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede and preempt any prior understandings, agreements or representations by or among the parties, written and oral, that may have related to the subject matter hereof in any way.

6.8. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. (a) This Agreement, and all claims or causes of action (whether at law, in contract or in tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance hereof, shall be governed by and construed in accordance with the Laws of the State of Delaware, without giving effect to any choice or conflict of Law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Court of Chancery of the State of Delaware (and any appellate court of the State of Delaware) and the Federal courts of the United States of America located in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any Action with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to lawfully serve process, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and (c) to the fullest extent permitted by applicable Law, that (i) the Action in any such court is brought in an inconvenient forum, (ii) the venue of such Action is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

(b) Each party hereto hereby waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any Action arising out of or relating to this Agreement. Each party hereto (i) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such party would not, in the event of any Action, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other parties hereto have been induced to enter into this Agreement, by, among other things, the mutual waiver and certifications in this Section 6.8.

6.9. Amendment; Waiver; Expenses.

(a) This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto. Each party may waive any right of such party hereunder by an instrument in writing signed by such party and delivered to Parent, the Company and the Stockholder.

(b) The Stockholder agrees that it is solely responsible (without reimbursement from the Company) for all costs and expenses (including all fees and expenses of

counsel) incurred by the Stockholder in connection with this Agreement and the Registration Rights Agreement.

6.10. Remedies. All rights, powers and remedies provided under this Agreement or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise or beginning of the exercise of any thereof by any party shall not preclude the simultaneous or later exercise of any other such right, power or remedy by such party.

6.11. Severability. Any term or provision of this Agreement which is determined by a court of competent jurisdiction to be invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction, and if any provision of this Agreement is determined to be so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable, in all cases so long as neither the economic nor legal substance of the transactions contemplated hereby is affected in any manner adverse to any party or its stockholders or partners, as applicable. Upon any such determination, the parties shall negotiate in good faith in an effort to agree upon a suitable and equitable substitute provision to effect the original intent of the parties as closely as possible and to the end that the transactions contemplated hereby shall be fulfilled to the maximum extent possible.

6.12. Successors and Assigns; Third Party Beneficiaries. Neither this Agreement nor any of the rights or obligations of any party under this Agreement shall be assigned, in whole or in part (by operation of law or otherwise), by any party without the prior written consent of the other parties hereto. Subject to the foregoing, this Agreement shall bind and inure to the benefit of and be enforceable by the parties hereto and their respective successors and permitted assigns. Nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties hereto or their respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement.

6.13. Stockholder Capacity. The restrictions and covenants of the Stockholder hereunder shall not be binding, and shall have no effect, in any way with respect to any director or officer of the Company or any of its Subsidiaries in such Person’s capacity as such a director or officer, nor shall any action taken by any such director or officer in his or her capacity as such be deemed a breach by the Stockholder of this Agreement.

ANNEX A

IRREVOCABLE PROXY

Dated as of February 25, 2008

The undersigned Stockholder (the “Stockholder”) of National Medical Health Card Systems, Inc., a Delaware corporation (the “Company”), hereby irrevocably (to the fullest extent permitted by law) appoints Xxxxxx Xxxxx and Xxxxxxx Xxxx, as the sole and exclusive attorneys and proxies of the undersigned, with full power of substitution and resubstitution, to vote and exercise all voting and related rights (to the full extent that the undersigned is entitled to do so) with respect to all of the shares of capital stock of the Company that now are or hereafter may be beneficially owned by the undersigned, and any and all other shares or securities of the Company issued or issuable in respect thereof on or after the date hereof (collectively, the “Covered Shares”), in accordance with the terms of this Proxy. The Covered Shares beneficially owned by the Stockholder as of the date of this Proxy are listed on the signature page of this Proxy, along with the number(s) of the stock certificate(s) representing such Covered Shares. Upon the Stockholder’s execution of this Proxy, any and all prior proxies given by the undersigned with respect to any Covered Shares are hereby revoked and terminated, and the Stockholder agrees not to grant any subsequent proxies with respect to the Covered Shares, with respect to any of the matters referred to in any of clauses (a) through (c) below until after the Expiration Time (as defined below).

This Proxy is irrevocable (to the fullest extent permitted by law), is coupled with an interest and is granted pursuant to that certain Stockholder Agreement of even date herewith (the “Stockholder Agreement”) by and among SXC Health Solutions Corp., a corporation organized under the laws of Yukon Territory, Canada (“Parent”), the Company and the undersigned Stockholder of the Company, and is granted in consideration of Parent entering into that certain Agreement and Plan of Merger of even date herewith (as it may hereafter be amended from time to time in accordance with the provisions thereof, the “Merger Agreement”) by and among Parent, SXC Health Solutions, Inc., a Texas corporation (“US Corp.”), Comet Merger Corporation, a newly-formed Delaware corporation that is wholly-owned by US Corp. and an indirect wholly-owned subsidiary of Parent (“Merger Sub”), and the Company. The Merger Agreement provides that Merger Sub will commence an exchange offer (the “Offer”) to acquire all of the outstanding shares of common stock, par value $0.001 per share, of the Company (“Company Common Stock”), and following the consummation of the Offer (or, subject to certain conditions, in lieu thereof), Merger Sub will merge with and into the Company (the “Merger”) and the Stockholder will be entitled to receive the merger consideration specified therein. The term “Expiration Time”, as used in this Proxy, shall mean the earliest to occur of (i) the Operative Date, (ii) a Change in Recommendation, (iii) the termination of the Merger Agreement in accordance with its terms, and (iv) the termination of the Stockholder Agreement in accordance with its terms.

The attorneys and proxies named above, and each of them, are hereby authorized and empowered by the Stockholder, at any time prior to the Expiration Time, to act as the Stockholder’s attorney and proxy to vote all of the Covered Shares, and to exercise all voting, consent and similar rights of the undersigned with respect to all of the Covered Shares

(including, without limitation, the power to execute and deliver written consents) at every annual or special meeting of stockholders of the Company (and at every adjournment or postponement thereof), and in every written consent in lieu of such meeting:

(a) in favor of the adoption of the Merger Agreement and any related proposal in furtherance thereof, as reasonably requested by Parent, submitted for the vote or written consent of stockholders;

(b) against any action or agreement submitted for the vote or written consent of stockholders that the Stockholder knows is in opposition to, or competitive or materially inconsistent with, the Offer or the Merger or that the Stockholder knows would result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company contained in the Merger Agreement, or of the Stockholder contained in the Stockholder Agreement; and

(c) against any Acquisition Proposal (as defined in the Merger Agreement) and against any other action, agreement or transaction submitted for the vote or written consent of stockholders that the Stockholder knows would impede, interfere with, delay, postpone, discourage, frustrate the purposes of or adversely affect the Offer or the Merger or the other transactions contemplated by the Merger Agreement or the Stockholder Agreement or the performance by the Company of its obligations under the Merger Agreement or by the Stockholder of its obligations under the Stockholder Agreement, including, but not limited to: (A) any extraordinary corporate transaction, such as a merger, consolidation or other business combination involving the Company or any subsidiary of the Company; (B) any sale, lease or transfer of a material amount of assets of the Company (including capital stock or other equity interests in its Subsidiaries) or any subsidiary of the Company; (C) any reorganization, recapitalization, dissolution or liquidation of the Company or any subsidiary of the Company; (D) any change in a majority of the board of directors of the Company; (E) any amendment to the Company’s certificate of incorporation or bylaws (except for any amendment to increase the authorized capital stock); and (F) any change in the capitalization of the Company or the Company’s corporate structure.

Any term or provision of this Proxy that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the Stockholder agrees that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Proxy shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Stockholder agrees to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

The restrictions and covenants of the Stockholder hereunder shall not be binding, and shall have no effect, in any way with respect to any director or officer of the Company or any of its Subsidiaries in such Person’s capacity as such a director or officer, nor shall any action taken by any such director or officer in his or her capacity as such be deemed a breach by the Stockholder of this Proxy.

Any obligation of the Stockholder hereunder shall be binding upon the successors and assigns of the Stockholder.

This Proxy shall terminate, and be of no further force and effect, automatically upon the Expiration Time.
