The closing (the “Closing”) of the Merger shall take place at the offices of ▇▇▇▇▇▇▇▇▇ Will & ▇▇▇▇▇ LLC, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇ at 10:00 a.m., Central time, on a date to be specified by Insys and NeoPharm, which shall be no earlier than November 8, 2010 and, on or after that date, no later than the second Business Day following the satisfaction or (to the extent permitted by law) waiver by the party or parties entitled to the benefits thereof of the conditions set forth in Article VII (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or (to the extent permitted by law) waiver of those conditions), or at such other place, time and date as shall be agreed in writing between NeoPharm and Insys; provided, however, that, if any of the conditions set forth in Article VII is not satisfied or (to the extent permitted by law) waived on such second Business Day, then the Closing shall take place on the first Business Day on which all such conditions shall have been satisfied or (to the extent permitted by law) waived. The date on which the Closing occurs is referred to in this Agreement as the “Closing Date.”

1.3 Effective Time. Subject to the provisions of this Agreement, as soon as practicable on the Closing Date, the parties shall file with the Secretary of State of the State of Delaware a certificate of merger in such form as required by, and executed and acknowledged in accordance with, the relevant provisions of the Delaware Law, and, as soon as practicable on or after the Closing Date, shall make all other filings required under the Delaware Law or by the Secretary of State of the State of Delaware in connection with the Merger. The Merger shall become effective at the time that the certificate of merger relating to the Merger (the “Certificate of Merger”) has been duly filed with the Secretary of State of the State of Delaware, or at such later time as NeoPharm and Insys shall agree and specify in the Certificate of Merger (the time the Merger becomes effective being the “Effective Time”).

1.4 Effects. The Merger shall have the effects set forth in this Agreement and Section 259 of the Delaware Law.

1.5 Surviving Corporation Certificate of Incorporation and By-Laws. The certificate of incorporation of Insys, as in effect immediately prior to the Effective Time, shall be the certificate of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable law. The by-laws of Insys as in effect immediately prior to the Effective Time shall be the by-laws of the Surviving Corporation, until thereafter changed or amended as provided therein or by applicable law.

ARTICLE II

EFFECT ON CAPITAL STOCK;

EXCHANGE OF CERTIFICATES

2.1 Effect on Capital Stock.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of Insys, NeoPharm, Merger Sub or the holder of any shares of capital stock of Insys or Merger Sub:

(i) Capital Stock of Merger Sub. Each share of common stock, par value $.01 per share, of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be converted into one fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(ii) Cancellation of Treasury Stock. Each share of common stock, par value $.001 per share, of Insys (such shares, the “Insys Common Stock”), issued and outstanding immediately prior to the Effective Time that is owned by Insys shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(iii) Conversion of Insys Common Stock. Subject to Section 2.2(c), each share of Insys Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 2.1(a)(ii)), shall be converted into 0.133857945 fully paid and nonassessable shares of common stock, par value $0.0002145 per share, of NeoPharm (the “NeoPharm Common Stock”) and 0.102038229 fully paid and nonassessable shares of Convertible Preferred Stock (such shares of NeoPharm Common Stock and Convertible Preferred Stock into which shares of Insys Common Stock are converted pursuant to this Section 2.1(a)(iii), the “Merger Consideration”). All shares of Insys Common Stock converted pursuant to this Section 2.1(a)(iii), when so converted, shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented shares of Insys Common Stock (a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive certificates representing the Merger Consideration.

(b) Certain Adjustments. If, between the date of this Agreement and the Effective Time (and as permitted by Article V), the outstanding shares of NeoPharm Common Stock or Insys Common Stock shall have been changed into a different number of shares or a different class of shares by reason of any stock dividend, subdivision, reorganization, reclassification, recapitalization, stock split, reverse stock split, combination or exchange of shares, or any similar event shall have occurred, then the Merger Consideration shall be appropriately and proportionately adjusted to provide to the holders of NeoPharm Common Stock and the holders of Insys Common Stock the same economic effect as contemplated by this Agreement prior to such event.

2.2 Exchange of Certificates.

(a) Exchange Procedures. At the Closing, NeoPharm shall deliver to each holder of record of a Certificate whose shares were converted pursuant to Section 2.1(a)(iii) into the Merger Consideration, upon proper surrender of such Certificate, stock certificates representing that number of whole shares of NeoPharm Common Stock and that number of whole shares of Convertible Preferred Stock into which the aggregate number of shares of Insys Common Stock previously represented by such Certificate pursuant to Section 2.1 has been converted, and the Certificate so surrendered shall immediately be canceled.

(b) No Further Ownership Rights in Insys Common Stock. The shares of NeoPharm Common Stock and Convertible Preferred Stock delivered upon conversion of shares of Insys Common Stock shall be deemed to have been delivered and paid in full satisfaction of all rights pertaining to such shares of Insys Common Stock. From and after the Effective Time, (i) all holders of Certificates shall cease to have any rights as stockholders of Insys other than the right to receive the Merger Consideration, and (ii) the stock transfer books of Insys shall be closed with respect to all shares of Insys Common Stock outstanding immediately prior to the Effective Time. From and after the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Insys Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates formerly representing shares of Insys Common Stock are presented to the Surviving Corporation or NeoPharm for any reason, such Certificates shall be canceled and exchanged as provided in this Article II.

(c) No Fractional Shares. No fractional shares of NeoPharm Common Stock or Convertible Preferred Stock shall be issued in connection with the Merger, no certificates or scrip representing fractional shares of NeoPharm Common Stock or Convertible Preferred Stock shall be delivered upon the conversion of Insys Common Stock pursuant to Section 2.1, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a holder of NeoPharm Common Stock or Convertible Preferred Stock. Notwithstanding any other provision of this Agreement, each holder of shares of Insys Common Stock converted pursuant to the Merger shall receive only that number of full shares of NeoPharm Common Stock and Convertible Preferred Stock to which such holder shall be entitled (after aggregating all shares represented by the Certificates delivered by such holder).

(d) Withholding Rights. NeoPharm shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of a Certificate pursuant to this Agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under applicable tax law. Any amounts so deducted, withheld and paid over to the appropriate taxing authority shall be treated for all purposes of this Agreement as having been paid to the holder of the Certificate in respect of which such deduction or withholding was made.

(e) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by NeoPharm, the posting by such Person of a bond, in such reasonable amount as NeoPharm may direct, as indemnity against any claim that may be

made against it with respect to such Certificate, shall deliver, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration.

(b) As used in this Agreement, “Competing Transaction” means, with respect to NeoPharm, any of (i) a transaction, including any tender offer, exchange offer or share exchange, pursuant to which any third Person (or group) other than the other party to this Agreement or such third Person’s Affiliates, or the stockholders of such third Person, directly or indirectly, acquires or would acquire beneficial ownership (as defined in Rule 13d-3 under the Securities Exchange Act of 1934) of 10% or more of the outstanding shares of NeoPharm Common Stock or of the outstanding voting power of NeoPharm (or options, rights or warrants to purchase, or securities convertible into or exchangeable for, such common stock or other securities representing such voting power), whether from NeoPharm or pursuant to a tender offer or exchange offer or otherwise, (ii) a merger, share exchange, consolidation or business combination pursuant to which any third Person or group of Persons (other than Insys or its Affiliates) party thereto, or the stockholders of such third Person or Persons, beneficially owns or would beneficially own 10% or more of the outstanding shares of common stock or the outstanding voting power of NeoPharm, or, if applicable, any surviving entity or the parent entity resulting from any such transaction, immediately upon consummation thereof, (iii) a recapitalization of NeoPharm or any transaction similar to a transaction referred to in clause (ii) above involving NeoPharm pursuant to which any third Person or group of Persons (other than Insys or its Affiliates) party thereto, or its stockholders, beneficially owns or would beneficially own 10% or more of the outstanding shares of common stock or the outstanding voting power of NeoPharm or, if applicable, the parent entity resulting from any such transaction immediately upon consummation thereof or (iv) any transaction pursuant to which any third Person or group of Persons (other than Insys or its Affiliates) directly or indirectly (including by way of merger, consolidation, share exchange, other business combination, partnership, joint venture or otherwise) acquires or would acquire control of assets of NeoPharm representing 10% or more of consolidated revenues, for the last 12 full calendar months or the fair market value of all the assets of NeoPharm immediately prior to such transaction.

(c) NeoPharm shall (i) promptly advise Insys orally and in writing of any request for confidential information in connection with a NeoPharm Acquisition Proposal or of any NeoPharm Acquisition Proposal, the material terms and conditions of such request or the NeoPharm Acquisition Proposal and the identity of the person making such request or NeoPharm Acquisition Proposal, and (ii) keep Insys promptly advised of all significant developments which could reasonably be expected to culminate in the NeoPharm Board exercising any of its rights under Section 5.5(d)

(d) Notwithstanding anything to the contrary set forth in this Section 5.5 or elsewhere in this Agreement, if at any time prior to the Effective Time or the valid termination of this Agreement pursuant to Article VIII, (i) NeoPharm has otherwise complied with its obligations under Section 5.5(a) and NeoPharm has received from a third party a written NeoPharm Acquisition Proposal that the NeoPharm Board (acting through the Special Committee or otherwise) believes in good faith to be bona fide, (ii) the NeoPharm Board (acting through the Special Committee or otherwise) determines in good faith, after consultation with its financial advisors and legal counsel, that such NeoPharm Acquisition Proposal either constitutes or is reasonably likely to lead to a Superior Proposal (as defined below), (iii) the NeoPharm Board determines (acting through the Special Committee or otherwise) in good faith, after consultation with its legal counsel, that failure to take such action would be inconsistent with its fiduciary obligations to the NeoPharm’s stockholders under Delaware Law, (iv) NeoPharm provides Insys at least two business days’ prior written notice of its intention to take such action, which notice shall include the information with respect to such NeoPharm Acquisition Proposal that is specified in Section 5.5(c), and (v) at the end of such two business day period, the NeoPharm Board concludes in good faith, after consultation with its outside legal counsel and financial advisors (and taking into account any adjustment or modification of the terms of this Agreement proposed by Insys), that the NeoPharm Acquisition Proposal continues to be a Superior Proposal and that the failure to take such action would be inconsistent with its fiduciary obligations to the NeoPharm’s stockholders under Delaware Law, then NeoPharm may (A) furnish information regarding NeoPharm to the Person making the NeoPharm Acquisition Proposal and (B) participate in discussions or negotiations with the Person making the NeoPharm Acquisition Proposal regarding the NeoPharm Acquisition Proposal.

(e) For purposes of this Agreement, “Superior Proposal” shall mean any bona fide written NeoPharm Acquisition Proposal not solicited in violation of Section 5.5, that (i) the NeoPharm Board (acting through the Special Committee or otherwise) determines in its good faith judgment, after receiving the advice of its financial advisor, is more favorable from a financial point of view to the NeoPharm stockholders (in their capacity as such) than the Merger, (ii) is not subject to a financing or due diligence condition and (iii) the NeoPharm Board (acting through the Special Committee or otherwise) determines is reasonably capable of being consummated on the terms proposed, taking into account all financing, legal, regulatory and other aspects of such proposal and any other relevant factors permitted by applicable law.

9.4 Interpretation. When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. 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. Any capitalized term used in any Exhibit but not otherwise defined therein shall have the meaning assigned to such term in this Agreement. 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 words “hereof,” “hereto,” “hereby,” “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. The term “or” is not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. Any agreement, instrument or law defined or referred to herein means such agreement, instrument or law as from time to time amended, modified or supplemented, unless otherwise specifically indicated. References to a person are also to its permitted successors and assigns. Unless otherwise specifically indicated, all references to “dollars” and “$” will be deemed references to the lawful money of the United States of America. No provision of this Agreement will be interpreted in favor of, or against, any of the parties to this Agreement by reason of the extent to which any such party or its counsel participated in the drafting thereof or by reason of the extent to which any such provision is inconsistent with any prior draft of this Agreement, and no rule of strict construction will be applied against any party hereto. The Insys Disclosure Schedule and the NeoPharm Disclosure Schedule, as well as all other schedules and all exhibits hereto, will be deemed part of this Agreement and included in any reference to this Agreement. The Insys Disclosure Schedule and the NeoPharm Disclosure Schedule set forth items of disclosure with specific reference to the particular Section or subsection of this Agreement to which the information in the Insys Disclosure Schedule or NeoPharm Disclosure Schedule, as the case may be, relates; provided, however, that any fact or item that is disclosed in any section of the Insys Disclosure Schedule or the NeoPharm Disclosure Schedule so as to make its relevance (i) to other representations made elsewhere in the Agreement, (ii) to the information called for by other sections of the Insys Disclosure Schedule or the NeoPharm Disclosure Schedule or (iii) to the annexes or exhibits to this Agreement reasonably apparent shall be deemed to qualify such representations or to be disclosed in such other sections of the Insys Disclosure Schedule, the NeoPharm Disclosure Schedule or the annexes or exhibits to this Agreement, as the case may be,

notwithstanding the omission of any appropriate cross-reference thereto; provided, further, that, notwithstanding anything in this Agreement to the contrary, the inclusion of an item in either such disclosure schedule as an exception to a representation or warranty will not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item has had or would reasonably be expected to have a Material Adverse Effect on Insys or NeoPharm, as the case may be. This Agreement will not be interpreted or construed to require any Person to take any action, or fail to take any action, if to do so would violate any applicable law. References to the “other party” or “either party” will be deemed to refer to NeoPharm and Merger Sub, collectively, on the one hand, and Insys, on the other hand. All electronic communications from a Person shall be deemed to be “written” for purposes of this Agreement.

9.5 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as either the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party or such party waives its rights under this Section 9.5 with respect thereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

9.6 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties.

9.7 Entire Agreement; No Third Party Beneficiaries. This Agreement, taken together with the Insys Disclosure Schedule and the NeoPharm Disclosure Schedule and the Contingent Payment Right Agreement, (a) constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the Merger and the other transactions contemplated by this Agreement and (b) except as provided in Section 6.5 or the Contingent Payment Rights Agreement, are not intended to confer upon any Person other than the parties any rights or remedies.

9.8 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER ANY APPLICABLE PRINCIPLES OF CONFLICT OF LAWS OF THE STATE OF DELAWARE.

9.9 Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties without the prior written consent of the other parties. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

9.10 Specific Enforcement. The parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor and therefore fully intend for specific performance to be the principal remedy for breaches of this Agreement. It is accordingly agreed that, prior to the termination of this Agreement pursuant to Article VIII, the parties shall be entitled to an Injunction or Injunctions to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement in any court referred to in Section 9.11(a), without proof of actual damages, this being in addition to any other remedy to which they are entitled at law or in equity. The parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, nor to object to a remedy of specific performance on the basis that a remedy of monetary damages would provide an adequate remedy for any such breach. Each party further acknowledges and agrees that the agreements contained in this Section 9.10 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, the other party would not enter into this Agreement. Each party further agrees that no other party hereto or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 9.10, and each party hereto irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

9.11 Jurisdiction. Each of the parties hereto hereby (a) agrees that any claim, suit, action or other proceeding, directly or indirectly, arising out of, under or relating to this Agreement, its negotiation or the transactions contemplated by this Agreement, will be heard and determined in the Chancery Court of the State of Delaware (and each agrees that no such claim, action, suit or other proceeding relating to this Agreement will be brought by it or any of its affiliates except in such court), subject to any appeal, provided that if jurisdiction is not then available in the Chancery Court of the State of Delaware, then any such claim, suit, action or other proceeding may be brought in any Delaware state court or any federal court located in the State of Delaware and (b) irrevocably and unconditionally submits to the exclusive jurisdiction of any such court in any such claim, suit, action or other proceeding and irrevocably and unconditionally waives the defense of an inconvenient forum to the maintenance of any such claim, suit, action or other proceeding. Each of the parties hereto further agrees that, to the fullest extent permitted by applicable law, service of any process, summons, notice or document by U.S. registered mail to such Person’s respective address set forth in Section 9.2 will be effective service of process for any claim, action, suit or other proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. The parties hereto hereby agree that a final judgment in any such claim, suit, action or other proceeding will be conclusive, subject to any appeal, and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law. In connection with any such proceeding that results in a judgment, the non-prevailing party will pay the prevailing party its reasonable costs and expenses (including attorney’s fees and expenses) incurred in connection with such proceeding.

9.12 Waiver of Jury Trial. 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 SUIT, ACTION OR OTHER PROCEEDING,

DIRECTLY OR INDIRECTLY, ARISING OUT OF, UNDER OR RELATING TO THIS AGREEMENT, ITS NEGOTIATION OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY HERETO (A) 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, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) 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 9.12.

9.13 Publicity. Insys and NeoPharm shall consult with each other before issuing, and give each other the opportunity to review and comment upon, any press release or other public statements with respect to the transactions contemplated by this Agreement, including the Merger, and shall not issue any such press release or make any such public statement prior to such consultation, except as such party may reasonably conclude may be required by applicable law or court process.

IN WITNESS WHEREOF, Insys, NeoPharm and Merger Sub have caused this Agreement to be executed by their respective officers thereunto duly authorized as of the date first above written.

PART II

CONTINGENT PAYMENT RIGHTS

Section 1. CPRs.

The CPRs represent the right of Holders to receive contingent cash payments pursuant to this Agreement. Each Holder shall be entitled to one CPR for each share of NeoPharm Common Stock owned by such Holder immediately prior to the Effective Time.

Section 2. Nontransferable.

The CPRs shall not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted Transfer.

Section 3. No Certificate; Registration; Registration of Transfer; Change of Address.

3.1 The CPRs shall not be evidenced by a certificate or other instrument.

3.2 The Rights Agent shall keep a register (the “CPR Register”) for the purpose of registering CPRs and transfers of CPRs as herein provided. The CPR Register will show one position for Cede & Co. representing all the CPRs issued with respect to the shares of NeoPharm Common Stock held by DTC on behalf of beneficial owners of shares of NeoPharm Common Stock as of immediately prior to the time the Merger becomes effective. Neither NeoPharm nor the Rights Agent will have any responsibility whatsoever directly to the beneficial owners with respect to transfers of CPRs unless and until such CPRs are transferred into the name of such beneficial owners in accordance with Section 2.2 of this Agreement. With respect to any payments to be made under Section 2.4 below, the Rights Agent will accomplish the payment to any beneficial owners of shares of NeoPharm Common Stock held of record by Cede & Co., as nominee, by sending one lump payment to DTC. The Rights Agent will have no responsibilities whatsoever with regards to distribution of payments by DTC to such beneficial owners.

3.3 Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CPR must be in writing and accompanied by a written instrument of transfer in form reasonably satisfactory to the Right Agent, and NeoPharm, duly executed by the Holder thereof, his attorney duly authorized in writing, personal representative or survivor and setting forth in reasonable detail the circumstances relating to the transfer and the authority of the party presenting the CPR for transfer, which authority shall include, if applicable, a signature guarantee from an eligible guarantor institution participating in a signature guarantee program approved by the Securities Transfer Association and any other reasonable evidence of authority

that may be required by the Rights Agent. Upon receipt of such written notice, NeoPharm shall, subject to its reasonable determination that the transfer instrument is in proper form and the transfer otherwise complies with the other terms and conditions herein (including the provisions of Section 2.2), instruct the Rights Agent to register the transfer of the CPRs in the CPR Register. All duly transferred CPRs registered in the CPR Register shall be the valid obligations of NeoPharm, evidencing the same right, and shall entitle the transferee to the same benefits and rights under this Agreement, as those held by the transferor. No transfer of a CPR shall be valid until registered in the CPR Register, and any transfer not duly registered in the CPR Register will be void ab initio. Any transfer or assignment of the CPRs shall be without charge (other than the cost of any transfer tax) to the Holder.

3.4 A Holder may make a written request to the Rights Agent to change such Holder’s address of record in the CPR Register. The written request must be duly executed by the Holder. Upon receipt of such written notice, the Rights Agent shall promptly record the change of address in the CPR Register.

Section 4. Payment Procedures.

4.1 If (i) the Merger has occurred, and (ii) the CPR Payment Event shall occur before the fifth anniversary of the Effective Date of the Merger, then, provided that doing so is not prohibited by or in violation of any law, within nine months following the occurrence of the CPR Payment Event NeoPharm shall deliver to the Rights Agent (i) a notice to the effect that the Holders are entitled to receive the CPR Payment Amount and (ii) $20,000,000 in cash, representing the aggregate CPR Payment Amount payable to the Holders.

4.2 Within five Business Days after receiving the notice and cash described in Section 2.4(a), the Rights Agent shall pay the CPR Payment Amount to each of the Holders (the amount which each Holder is entitled to receive will be based on the applicable CPR Payment Amount multiplied by the number of CPRs held by such Holder as reflected on the CPR Register) by check mailed to the address of each Holder as reflected in the CPR Register as of the close of business on the last Business Day prior to such CPR Payment Date. The Rights Agent shall have no obligation to pay the CPR Amount except to the extent it has received the necessary funds from NeoPharm.

4.3 NeoPharm shall be entitled to deduct and withhold, or cause to be deducted or withheld, from each payment pursuant to Section 2.4(b), such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld and paid over to or deposited with the relevant Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made. Prior to making any such tax withholdings or causing any such tax withholdings to be made with respect to any Holder, the Rights Agent shall, to the extent practicable, provide notice to the Holder of such potential withholding and a reasonable opportunity for the Holder to provide any necessary tax forms (including an IRS Form W-9 or an applicable IRS Form W-8) in order to avoid or reduce such withholding amounts. The CPRs shall not be treated as an interest in a joint venture or partnership for tax purposes.

4.4 Any portion of any CPR Payment Amount that remains undistributed to the Holders for one month after any CPR Payment Date shall be delivered by the Rights Agent to NeoPharm, upon demand, and any Holder shall thereafter look only to NeoPharm for payment of such CPR Payment Amount, but shall have no greater rights against NeoPharm than may be accorded to general unsecured creditors of NeoPharm under applicable law.

4.5 Neither NeoPharm nor the Rights Agent shall be liable to any person in respect of any CPR Payment Amount delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any CPR Payment Amount has not been paid prior to two years after the CPR Payment Date (or immediately prior to such earlier date on which the CPR Payment Amount would otherwise escheat to or become the property of any Governmental Entity), any such CPR Payment Amount shall, to the extent permitted by applicable law, become the property of NeoPharm, free and clear of all claims or interest of any person previously entitled thereto.

(f) The Company acknowledges that the bank accounts maintained by Computershare in connection with the services provided under this Agreement will be in its name and that Computershare may receive investment earnings in connection with the investment at Computershare risk and for its benefit of funds held in those accounts from time to time.

Section 5. No Voting, Dividends Or Interest; No Equity Or Ownership Interest In NeoPharm.

5.1 The CPRs shall not have any voting or dividend rights, and interest shall not accrue on any amounts payable on the CPRs to any Holder.

5.2 The CPRs shall not represent any equity or ownership interest in NeoPharm or in any constituent company to the Merger.

Section 6. Ability To Abandon The CPR.

The Holder of a CPR may at any time at its option abandon all of its rights in any CPR by transferring the CPR to NeoPharm without consideration therefor. Nothing in this Section 2.6 is intended to prohibit NeoPharm from offering to acquire CPRs for consideration in its sole discretion.

PART III

THE RIGHTS AGENT

Section 1. Certain Duties And Responsibilities.

The Rights Agent shall not have any liability for any actions taken or not taken in connection with this Agreement, except to the extent of its willful misconduct, bad faith or gross negligence. No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers. Notwithstanding anything contained herein to the contrary, the Rights Agent’s aggregate liability during any term of this Agreement

with respect to, arising from, or arising in connection with this Agreement, or from all services provided or omitted to be provided under this Agreement, whether in contract, or in tort, or otherwise, is limited to, and shall not exceed, the amounts paid hereunder by the NeoPharm to the Rights Agent as fees and charges, but not including reimbursable expenses.

Section 2. Certain Rights of Rights Agent.

The Rights Agent undertakes to perform such duties and only such duties as are specifically set forth in this Agreement, and no implied covenants or obligations shall be read into this Agreement against the Rights Agent. In addition:

2.1 the Rights Agent may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

2.2 whenever the Rights Agent shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Rights Agent may, in the absence of bad faith, gross negligence or willful misconduct on its part, rely upon a certificate signed by the chief executive officer, president, chief financial officer, any vice president, the controller, the treasurer or the secretary, in each case of NeoPharm, in his or her capacity as such an officer, and delivered to the Rights Agent.;

2.3 the Rights Agent may engage and consult with counsel of its selection and the written advice of such counsel or any opinion of counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

2.4 the permissive rights of the Rights Agent to do things enumerated in this Agreement shall not be construed as a duty;

2.5 the Rights Agent shall not be required to give any note or surety in respect of the execution of such powers or otherwise in respect of the premises;

2.6 NeoPharm agrees to indemnify Rights Agent for, and hold Rights Agent harmless against, any loss, liability, claim, demands, suits or expense arising out of or in connection with Rights Agent’s duties under this Agreement, including the costs and expenses of defending Rights Agent against any claims, charges, demands, suits or loss, unless such loss shall have been determined by a court of competent jurisdiction to be a result of Rights Agent’s gross negligence, bad faith or willful or intentional misconduct; and

2.7 NeoPharm agrees (i) to pay the fees and expenses of the Rights Agent in connection with this Agreement as agreed upon in writing by Rights Agent and NeoPharm on or prior to the date hereof, and (ii) to reimburse the Rights Agent for all taxes and governmental charges, reasonable expenses and other charges of any kind and nature incurred by the Rights Agent in the execution of this Agreement (other than taxes measured by the Rights Agent’s net income).

Section 3. Resignation and Removal; Appointment of Successor.

3.1 The Rights Agent may resign at any time by giving written notice thereof to NeoPharm specifying a date when such resignation shall take effect, which notice shall be sent at least 60 days prior to the date so specified. NeoPharm shall have the right to remove Rights Agent at any time by a Board Resolution specifying a date when such removal shall take effect. Notice of such removal shall be given by NeoPharm to Rights Agent, which notice shall be sent at least 60 days prior to the date so specified.

3.2 If the Rights Agent shall resign, be removed or become incapable of acting, NeoPharm, by a Board Resolution, shall promptly appoint a qualified successor Rights Agent, which may be NeoPharm or a Holder. The successor Rights Agent so appointed shall, forthwith upon its acceptance of such appointment in accordance with this Section 3.3(b), become the successor Rights Agent.

3.3 NeoPharm shall give notice of each resignation and each removal of a Rights Agent and each appointment of a successor Rights Agent by mailing written notice of such event by first-class mail, postage prepaid, to the Holders as their names and addresses appear in the CPR Register. Each notice shall include the name and address of the successor Rights Agent. If NeoPharm fails to send such notice within ten days after acceptance of appointment by a successor Rights Agent, the successor Rights Agent shall cause the notice to be mailed at the expense of NeoPharm.

Section 4. Acceptance of Appointment By Successor.

Every successor Rights Agent appointed hereunder shall execute, acknowledge and deliver to NeoPharm and to the retiring Rights Agent an instrument accepting such appointment and a counterpart of this Agreement, and thereupon such successor Rights Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Rights Agent; but, on request of NeoPharm or the successor Rights Agent, such retiring Rights Agent shall execute and deliver an instrument transferring to such successor Rights Agent all the rights, powers and trusts of the retiring Rights Agent.

PART IV

Section 1. Amendments Without Consent of Holders.

1.1 Without the consent of any Holders, NeoPharm, when authorized by a Board Resolution, the Rights Agent, in the Rights Agent’s sole and absolute discretion, and the consent of Insys with respect to any amendments prior to the effective time of the Merger, at any time and from time to time, may amend this Agreement, for any of the following purposes:
