Item 1.01

Entry into a Material Definitive Agreement

On March 21, 2007, Unidym, Inc. (“Unidym”), a Delaware corporation and majority-owned subsidiary of Arrowhead Research Corporation (“Arrowhead”), and Unidym Acquisition, LLC (“Merger LLC”), a Delaware limited liability company and wholly-owned subsidiary of Unidym, entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Carbon Nanotechnologies, Inc. (“CNI”), a Delaware corporation, and William A. McMinn as stockholder representative. Pursuant to the Merger Agreement, CNI will be merged with and into Merger LLC, with Merger LLC remaining as the surviving entity after the merger (“Merger”). After giving effect to the Merger, Unidym will be the sole managing member of Merger LLC. There are no material relationships among Unidym and CNI or any of their respective affiliates or any of the other parties to the Merger Agreement or the related ancillary agreements, other than in respect of such agreements themselves.

At the effective time of the Merger, each outstanding share of capital stock of CNI, other than shares of Series E Preferred Stock of CNI, will be converted into the right to receive approximately 0.19 fully paid and non-assessable shares of Series A Preferred Stock of Unidym. Each outstanding share of Series E Preferred Stock of CNI will be converted into the right to receive approximately 2.58 fully paid and non-assessable shares of Series B Preferred Stock Unidym. In addition, in connection with the Merger, each currently outstanding share of Series A Preferred Stock of Unidym will be converted into one share of Series B Preferred Stock of Unidym. All outstanding restricted stock units under CNI’s restricted stock unit plan and warrants to purchase shares of CNI capital stock will be assumed by Unidym. The Merger Agreement also provides that 20% of the issued and outstanding capital stock of Unidym (calculated after giving effect to the Merger) will be placed into an escrow account to settle certain claims for indemnification for breaches of or inaccuracies in Unidym’s and CNI’s representations and warranties, covenants and agreements.

The Merger and the Merger Agreement have been unanimously approved by the board of directors of Unidym and CNI and has been approved by a majority of the stockholders of each of Unidym and CNI.

The Merger Agreement contains customary representations and warranties and covenants by each of the parties. The closing of the Merger is subject to customary closing conditions. The parties to the Merger Agreement anticipate completing the Merger as soon as all such closing conditions have been satisfied.

The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and is incorporated by reference.

Item 3.02

Unregistered Sales of Equity Securities

The disclosure set forth in Item 1.01 hereof is hereby incorporated by reference in this Item 3.02.

THE MERGER

1.1 The Merger. At the Effective Time, and subject to and upon the terms and conditions of this Agreement and the provisions of the DGCL, the Company shall be merged

with and into Merger LLC, the separate existence of the Company shall cease, and Merger LLC shall continue as the surviving company and as a wholly-owned subsidiary of Parent. The surviving company after the Merger is sometimes referred to herein as the “Surviving Company.”

1.2 Effective Time. Unless this Agreement is earlier terminated pursuant to Section 8.1, the closing of the transactions contemplated by this Agreement (the “Closing”) will take place as promptly as practicable, but on the date on which the conditions set forth in Article VI are satisfied or waived (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions), at the offices of Goodwin Procter LLP, 10250 Constellation Blvd., 21st Floor, Los Angeles, California 90067-6221, unless another place or date is agreed to by Parent and the Company. The date upon which the Closing occurs is herein referred to as the “Closing Date.” On the Closing Date, the parties hereto shall cause the Merger to be consummated by filing a properly executed Certificate of Merger satisfying the requirements of the DGCL and the LLC Act in the form attached hereto as Exhibit B (the “Certificate of Merger”) with the Secretary of State of the State of Delaware in accordance with the relevant provisions of the DGCL and the LLC Act (the time of acceptance by the Secretary of State of the State of Delaware of such filing being referred to herein as the “Effective Time”).

1.4 Operating Agreement.

At the Effective Time and by virtue of the Merger, the officers of the Parent immediately prior to the Effective Time shall remain the officers of the Surviving Company, each to hold office in accordance with the Bylaws of the Parent, in substantially the form set forth on Exhibit D (the “Parent Bylaws”).

1.7 Conversion of Securities; Escrow.

(a) Company Capital Shares. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger LLC, the Company or the Stockholders:

(i) Each Company Common Share outstanding immediately prior to the Effective Time, other than Company Common Shares held in treasury by the Company or owned by Parent or Merger LLC or which constitute Dissenting Shares (as defined below), shall, by virtue of the Merger and without any action on the part of the holder thereof automatically be canceled and extinguished and be converted into the right to receive, upon surrender of a certificate representing any such shares in the manner provided in Section 1.9 hereof and upon the terms and subject to the conditions set forth in this Agreement and net of withholding and other Taxes, the number of fully paid and nonassessable shares of Parent Series A Preferred Stock, in the number set forth on the Post-Merger Capitalization Schedule, attached as Exhibit E hereto.

(ii) Each Company Preferred Share outstanding immediately prior to the Effective Time, other than Company Preferred Shares held in treasury by the Company or owned by Parent or Merger LLC or which constitute Dissenting Shares (as defined below), shall, by virtue of the Merger and without any action on the part of the holder thereof automatically be canceled and extinguished and be converted into the right to receive, upon surrender of a certificate representing any such shares in the manner provided in Section 1.9 hereof and upon the terms and subject to the conditions set forth in this Agreement and net of withholding and other Taxes, the number of fully paid and nonassessable shares of Parent Series B Preferred Stock, in the number set forth on the Post-Merger Capitalization Schedule, attached as Exhibit E hereto.

(ii) Each share of Parent Series A Preferred Stock outstanding immediately prior to the Effective Time, other than Parent Preferred Shares which constitute Dissenting Shares (as defined below), shall, by virtue of the Merger and without any action on the part of the holder thereof automatically be canceled and extinguished and be converted into shares of Parent Series B Preferred Stock, in the number set forth on the Post-Merger Capitalization Schedule, attached as Exhibit E hereto.

-3-

(c) Qualified Investor Status. Parent shall not be required to deliver any Parent Preferred Shares to any holder of Company Capital Shares that is receiving Merger Consideration pursuant to Section 1.7(a) hereof unless Parent shall have received from each such holder a duly executed investor representation letter substantially in the form attached hereto as Exhibit F (each a “Representation Letter”) on or prior to the Closing Date.

(d) Cancellation of Parent-Owned and Company-Owned Stock. Each Company Capital Share held in the treasury of the Company and each Company Capital Share owned by Parent or Merger LLC immediately prior to the Effective Time shall be cancelled and extinguished without any conversion thereof, and no payment or distribution shall be made with respect thereto.

(e) Company Stock Rights.

(i) Company Options. The Company shall take all steps necessary to terminate the Company Equity Incentive Plans and all option agreements such that all outstanding Company Options shall be cancelled and extinguished as of the Effective Time. The Company shall obtain, prior to the Closing, the consent from each holder of a Company Option to the termination of the Company Option pursuant to this Section 1.7(e)(i).

(ii) Restricted Stock Units.

(A) Parent shall assume the RSU Plan and each unvested Restricted Stock Unit (“Assumed Restricted Stock Unit”) that is outstanding as of the Effective Time, together with the restricted stock unit agreement representing each such Restricted Stock Unit. Each Assumed Restricted Stock Unit shall thereafter be exercisable for such number of Parent Common Shares as set forth on the Post-Merger Capitalization Schedule, attached as Exhibit E hereto and the vesting schedule for such Assumed Restricted Stock Unit shall remain unchanged and as set forth in the restricted stock unit agreement for such Assumed Restricted Stock Unit without any acceleration of vesting whatsoever. The Company and the Administrator of the RSU Plan (the “Administrator”) shall take all actions necessary or required under the RSU Plan and the restricted stock unit agreements to cause the RSU Plan and all Assumed Restricted Stock Units to be assumed on the terms and conditions set forth in the preceding sentence such that the vesting of no Assumed Restricted Stock Unit is accelerated.

(B) Each issued and outstanding unvested Restricted Stock Unit that was not granted by CNI pursuant to the RSU Plan shall be exchanged into the right to receive, upon surrender of the restricted stock unit agreement therefor in accordance with this Agreement, a restricted stock unit exercisable for such number of Parent Common Shares (the “Parent Restricted Stock Units”) as set forth on the Post-Merger Capitalization Schedule, attached as Exhibit E hereto and the vesting schedule for such Parent Restricted Stock Unit shall remain unchanged and as set forth in the restricted stock unit agreement for such Parent Restricted Stock Unit without any acceleration of vesting whatsoever. All holders of unvested Restricted Stock Units that were not issued pursuant to the RSU Plan shall be obligated to deliver to Parent a duly executed Representation Letter on or prior to the Closing Date, and Parent shall not be required to deliver any restricted stock unit agreement related to the Parent Restricted Stock Units to be held by such recipient until Parent receives such Representation Letter.

-4-

(f) Company Warrant. Each unexercised and outstanding Company Warrant shall be exchanged into the right to receive, upon surrender of the Company Warrant therefor, a warrant exercisable for such number of shares of Parent Common Shares as set forth on the Post-Merger Capitalization Schedule, attached as Exhibit E hereto and terms of such Company Warrant shall remain unchanged and as set forth in the Company Warrant agreement. The holder of the Company Warrant shall be obligated to deliver to Parent a duly executed Representation Letter on or prior to the Closing Date and the Company shall take all necessary steps to obtain written evidence reasonably satisfactory to Parent as to the acceptance by the holder of the outstanding Company Warrant as to the foregoing.

(g) Escrow. At Closing, twenty percent (20%) of Parent’s issued and outstanding Parent Capital Shares shall be held in escrow pursuant to Article VII of this Agreement. The approval of this Agreement by the Stockholders will also constitute their approval of the terms and provisions of the Escrow Agreement, which is an integral term of the Merger. The Escrow Shares will be withheld in accordance with the provisions of Section 1.9 hereof. The delivery of the Escrow Shares will be made on behalf of the Stockholders and the holders of Parent Capital Shares in accordance with the provisions hereof, with the same force and effect as if such shares had been delivered by Parent directly to such holders and subsequently delivered by such holders to the Escrow Agent.

(h) No Fractional Shares. No fraction of a Parent Preferred Share will be issued, but in lieu thereof, each holder of Company Capital Shares who would otherwise be entitled to a fraction of a Parent Preferred Shares (after aggregating all fractional Parent Preferred Shares to be received by such holder) shall be entitled to receive from Parent such number of whole number of Parent Preferred Shares, rounded up or down to the nearest whole number (with a fractional interest equal to 0.5 rounded upward to the nearest whole number).

(i) Withholding Rights; Deductions from Consideration. Each of the Surviving Company and Parent shall be entitled to deduct and withhold from any payment to any Person under this Agreement or any other Transaction Agreements (i) such amounts as it is required to deduct and withhold with respect to the making of such payment or any other Tax withholding obligation with respect to the Merger under the Code or any provision of state, local or foreign Tax Law and (ii) to the extent applicable, the amount of any outstanding loans (including any accrued but unpaid interest thereon and any other amounts in respect thereof) owed by such Person to the Company as of the Closing. To the extent that amounts are so withheld or deducted by the Surviving Company or by Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction and withholding was made by the Surviving Company or by Parent, as the case may be.

(j) No Further Ownership Rights in Company Capital Shares. The amounts paid or payable upon the surrender for exchange of Company Capital Shares in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such Company Capital Shares, and there shall be no further registration of transfers on the records of the Surviving Company of Company Capital Shares which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Company for any reason, they shall be canceled and exchanged as provided in this Article I.

-5-

(k) Capital of Merger LLC. The ownership interests in Merger LLC immediately prior to the Effective Time shall be converted into and become the membership interests of the Surviving Company.

1.8 Dissenting Shares.

(a) Immediately after the execution and delivery of this Agreement, the Company shall solicit the approval by written consent of the execution and delivery by the Company of this Agreement and the consummation of the Merger, by the Stockholders holding the requisite number of shares of each class of Company Capital Shares required (the “Stockholder Approval”) to (i) approve the execution and delivery of this Agreement and the consummation of the Merger in accordance with the DGCL, the LLC Act and the Company Certificate of Incorporation, the Escrow Agreement and all other transactions contemplated hereby and thereby, and appoint William A. McMinn as the initial Stockholder Representative, and (ii) acknowledge that such approval is irrevocable and that such holder is aware of its rights to dissent pursuant to Section 262 of the DGCL, a copy of which was attached to such written consent, and that such holder has received and read a copy of Section 262 of the DGCL. The written consent shall be accompanied by an information statement containing (i) a description of the appraisal rights of holders of all Company Capital Shares available under Section 262 of the DGCL and (ii) such information concerning this Agreement and the transactions contemplated hereby as Parent shall have previously approved, and the form of Representation Letters to be completed and returned to the Company.

(b) After the effective date of the written consent described in Section 1.8(a), the Company shall give prompt notice of the taking of the actions described in Section 1.8(a) to all holders of Company Capital Shares not executing the written consent described therein.

(c) Notwithstanding any provision of this Agreement to the contrary, Company Capital Shares that are outstanding immediately prior to the Effective Time and which are held by Stockholders of the Company who shall not have voted in favor of the Merger or consented thereto in writing and who shall have demanded properly in writing appraisal for such shares in accordance with Section 262 of the DGCL (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to receive the Merger Consideration set forth in Section 1.8(a) hereof. Such stockholders shall be entitled to receive such consideration as is determined to be due with respect to such Dissenting Shares in accordance with the provisions of Section 262 of the DGCL, except that all Dissenting Shares held by stockholders of the Company who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to appraisal of such shares under Section 262 of the DGCL shall thereupon be deemed to have been converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration pursuant to Section 1.8(a) hereof in the manner provided in Section 1.8 hereof of the Certificate or Certificates that formerly evidenced by such Dissenting Shares.

-6-

(d) The Company shall give Parent and the Stockholder Representative (i) prompt notice of any written demands for appraisal of any Company Capital Shares, withdrawals of such demands, and any other instruments or notices served pursuant to the DGCL on the Company and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent and the Stockholder Representative, voluntarily make any payment with respect to any demands for appraisal of Company Capital Shares or offer to settle or settle any such demands. Notwithstanding the foregoing, to the extent that Parent or the Company (i) makes any payment or payments in respect of any Dissenting Shares in excess of the consideration that otherwise would have been payable in respect of such shares in accordance with this Agreement or (ii) incurs any other costs or expenses (including specifically, but without limitation, attorneys’ fees, costs and expenses in connection with any action or proceeding or in connection with any investigation) in respect of any Dissenting Shares (other than payments for such shares) (together “Dissenting Share Payments”), Parent shall be indemnified under the terms of Article VII (subject to the conditions and limitations therein) for the amount of such Dissenting Share Payments.

1.9 Surrender of Certificates.

(a) Parent shall act as exchange agent (the “Exchange Agent”) in the Merger. Parent shall deposit the Company Escrow Shares with the Escrow Agent out of the aggregate number of Parent Preferred Shares otherwise issuable pursuant to Section 1.7 hereof on behalf of the holders of Company Capital Shares and pursuant to Article VII hereof and the Escrow Agreement.

(b) Promptly after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates (the “Certificates”) which immediately prior to the Effective Time represented outstanding shares of Company Capital Shares whose shares were converted into the right to receive the Merger Consideration pursuant to Section 1.7(a) hereof, (i) a letter of transmittal (a “Letter of Transmittal”) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing Parent Preferred Shares and, in lieu of fractional shares thereof, cash pursuant to Section 1.7(h) hereof. Upon surrender of a Certificate (or Certificates) for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other customary documents as may be required pursuant to such instructions, the holder of such Certificate(s) shall be entitled to receive in exchange therefor a certificate representing the number of whole Parent Preferred Shares (less the number of Parent Preferred Shares to be deposited with the Escrow Agent on such holder’s behalf pursuant to Section 1.7(g) and Article VII hereof) to which such holder is entitled pursuant to Section 1.7(a) hereof, and the Certificate(s) so surrendered shall forthwith be canceled.

Such shares shall be beneficially owned by the holders on whose behalf such shares were deposited with the Escrow Agent and shall be available to Parent as provided in Article VII and the Escrow Agreement. Until so surrendered, each outstanding Certificate that,

-7-

prior to the Effective Time, represented shares of Company Capital Shares (other than Dissenting Shares) will be deemed from and after the Effective Time, for all corporate purposes, other than the payment of dividends, to evidence the ownership of the number of full Parent Preferred Shares into which such shares of Company Capital Shares shall have been so converted and the right to receive an amount in cash in lieu of the issuance of any fractional shares in accordance with Section 1.7(h) hereof.

(c) No dividends or other distributions declared or made after the Effective Time with respect to Parent Preferred Shares with a record date after the Effective Time will be paid to the holder of any unsurrendered Certificate with respect to the Parent Preferred Shares represented thereby until the holder of record of such Certificate shall surrender such Certificate in exchange for Parent Preferred Shares in accordance with the terms of this Agreement. Subject to applicable law, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole Parent Preferred Shares issued in exchange therefor, without interest, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole Parent Preferred Shares.

(d) If any certificate for Parent Preferred Shares is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it will be a condition of the issuance thereof that the Certificate so surrendered will be properly endorsed and otherwise in proper form for transfer and that the Person requesting such exchange will have paid to Parent or any agent designated by it any transfer or other taxes required by reason of the issuance of a certificate for Parent Preferred Shares in any name other than that of the registered holder of the Certificate surrendered, or established to the satisfaction of Parent or any agent designated by it that such tax has been paid or is not payable.

(e) Notwithstanding anything to the contrary in this Section 1.9, none of the Exchange Agent, Parent, the Surviving Company or any party hereto shall be liable to a holder of Parent Preferred Shares for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

(f) In the event any Certificates to be surrendered in accordance with Section 1.9(b) shall have been lost, stolen or destroyed, the Parent shall deem such lost, stolen or destroyed Certificates surrendered for purposes of Section 1.9(b), upon the receipt of an affidavit of that fact, in a form reasonably satisfactory to Parent, by the holder thereof pursuant to which such holder would agree to indemnify Parent and its Affiliates against any claim that may be made against Parent or its Affiliates with respect to the Certificates alleged to have been lost, stolen or destroyed.

1.10 Further Assurances. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Company with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Merger LLC, the officers, managers and directors of the Company and Merger LLC are fully authorized in the name of their respective corporation or company or otherwise to take, and will take, all such lawful and necessary action.

To the extent the Company’s actual Transition Obligations are in excess of twenty percent (20%) of the estimates set forth on Schedule 4.8, the Company will give Parent notice of such increased cash needs and the Company and Parent shall negotiate in good faith a share adjustment to the Parent’s stockholders to account for such increased expenses; provided, however, no share adjustment shall required if, as of the Closing Date, the sum of the Company’s Bank Debt and all payments made pursuant to this Section 4.8 aggregates less than $5.4 Million.

During the period from the Agreement Date through the Closing Date all revenues received on account of the Company or any of its Affiliates shall be promptly deposited into the existing bank accounts of the Company (or any new accounts established with the knowledge and consent of Parent) (the “Accounts”) and shall be used only to pay Transition Obligations.

-49-

(c) Unsecured Note of Parent. The Transition Obligations actually paid by Parent will be recorded on a simple grid note, evidencing an unsecured obligation of the Company to Parent, attached as Exhibit N.

ARROWHEAD SUBSIDIARY, UNIDYM, TO MERGE WITH CARBON

NANOTECHNOLOGIES, INC.

Combination Creates Leader in Carbon Nanotubes

PASADENA, Calif. – March 22, 2007 – Arrowhead Research Corporation (NASDAQ: ARWR) announced today that its majority-owned subsidiary, Unidym, Inc., has entered into a definitive agreement to merge with Carbon Nanotechnologies, Inc. (“CNI”). The transaction is expected to close in early April. The combined company, which will operate under the Unidym name, will have the dominant portfolio of carbon nanotube-related patents and be positioned as a leader in bringing carbon nanotube-based products to market.

“CNI is the largest manufacturer of carbon nanotubes in the world and has hundreds of customers, in addition to partnerships and licensing arrangements with companies like Motorola, Sumitomo, IBM, DuPont, and Johnson Matthey,” said R. Bruce Stewart, Arrowhead’s Chairman. “We believe this deal is transformational for the industry and will enable more rapid commercialization of products incorporating nanotubes since so much of the intellectual property can now be licensed from one company.”

CNI was founded in 2000 by the late Rice University professor Richard Smalley who received the Nobel Prize for his work in carbon nanotubes. His pioneering work led to a suite of patents that covers technologies being used today to develop nanotube-based products. CNI has more than 100 patents (including 54 issued U.S. patents) and patent applications covering compositions of matter, methods of manufacturing, processing and products incorporating carbon nanotubes, with over 5000 claims in various stages of prosecution.

“We chose Unidym as our partner because Unidym has the most advanced carbon nanotube-based electronic products with billion dollar market potential, as well as an impressive carbon nanotube patent portfolio of its own,” said Bob Gower, CEO of Carbon Nanotechnologies, Inc.

Unidym, founded by distinguished UCLA professor Dr. George Gruner, is developing carbon nanotube-based products for the electronics industry. The company’s first product is a transparent electrode that is intended to replace the indium tin oxide (ITO) electrodes in products such as flat-panel displays used in televisions, laptop computers, mobile phones and touch screens, solar cells, and solid state lighting. The total existing market for this product is approximately $1 billion. Unidym has already provided samples to potential customers in each of its target industries. Unidym’s second product is a carbon nanotube-based thin film transistor (TFT) intended for the emerging flexible (also known as printable) electronics industry.

“Unidym now has critical mass,” stated Sean Olson, President of Unidym. “Unidym will use its expansive patent portfolio to protect its first three products – transparent

electrodes, fuel cell electrodes, and thin film transistors – and to immediately pursue licensing opportunities for a range of other nanotube-based products such as targeted therapeutics, medical devices, field emission displays, batteries, sporting goods and composite materials.”

Upon closing, Arrowhead will retain majority-ownership of Unidym. Under the terms of the definitive agreement, all outstanding shares of capital stock of CNI will be converted into shares of Series A Preferred Stock of Unidym. In connection with the merger, Arrowhead will exchange $5.4 million worth of Arrowhead common stock for Series E preferred stock in CNI prior to the closing of the merger. In addition, Arrowhead is transferring to Unidym the rights and obligations of its research agreement with Duke University and the University of Florida and Arrowhead will accelerate $4 million of future capital contributions to Unidym on the closing date.
