AGREEMENT AND PLAN OF MERGER, dated as of September 23, 2007 (this “Agreement”), among C-COR INCORPORATED, a Pennsylvania corporation (“C-COR” or the “Company”), ARRIS GROUP, INC., a Delaware corporation (“ARRIS”), and AIR MERGER SUBSIDIARY, INC., a Delaware corporation and wholly owned subsidiary of ARRIS (the “Merger Subsidiary”). C-COR, ARRIS, and the Merger Subsidiary are herein referred to collectively as the “Parties” and each individually as a “Party.”

W I T N E S S E T H

WHEREAS, the Boards of Directors of C-COR, ARRIS and the Merger Subsidiary have determined that it is in the best interests of their respective stockholders that C-COR, ARRIS and the Merger Subsidiary enter into a business combination under which C-COR will merge with and into the Merger Subsidiary (the “Merger”) and, in connection therewith, to make certain representations, warranties and agreements in connection with the Merger;

WHEREAS, the Boards of Directors of C-COR, ARRIS and the Merger Subsidiary have determined that the Merger and the other transactions contemplated hereby are consistent with, and in furtherance of, their respective business strategies and goals and have each adopted and approved this Agreement and the Merger upon the terms and conditions set forth herein; and

WHEREAS, for federal income tax purposes, it is intended that the Merger shall constitute a tax-free reorganization under Section 368 of the Internal Revenue Code of 1986, as amended and the Treasury regulations promulgated thereunder (the “Code”);

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

ARTICLE I

THE MERGER

SECTION 1.1 —The Merger. At the Effective Time and subject to and upon the terms and conditions of this Agreement, the Pennsylvania Business Corporation Law (“Pennsylvania Law”) and the Delaware General Corporation Law (“Delaware Law”), the Merger shall be consummated, whereby C-COR shall be merged with and into the Merger Subsidiary, the separate corporate existence of C-COR shall cease, and the Merger Subsidiary shall continue as the surviving corporation, which shall be a wholly owned subsidiary of ARRIS. The Merger Subsidiary as the surviving corporation after the Merger is herein sometimes referred to as the “Surviving Corporation,” and C-COR as the non-surviving corporation after the Merger is herein sometimes referred to as the “Merged Corporation.”

SECTION 1.2 —Effective Time. As promptly as practicable after the satisfaction or waiver of the conditions set forth in Article VIII hereof and the consummation of the Closing

referred to in Section 7.2(b) hereof, the Parties shall cause the Merger to be consummated by filing (i) Articles of Merger (the “Articles of Merger”) with the Department of State of the Commonwealth of Pennsylvania with respect to the Merger and (ii) a Certificate of Merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware with respect to the Merger, in such form as required by, and executed in accordance with, the relevant provisions of Pennsylvania Law and Delaware Law, as applicable (the time of such filing being the “Effective Time”).

SECTION 1.3 —Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of Pennsylvania Law and Delaware Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of C-COR and the Merger Subsidiary shall continue with, or vest in, as the case may be, the Merger Subsidiary as the Surviving Corporation, and all debts, liabilities and duties of C-COR and the Merger Subsidiary shall continue to be, or become, as the case may be, the debts, liabilities and duties of the Merger Subsidiary as the Surviving Corporation. As of the Effective Time, the Surviving Corporation shall be a direct wholly owned subsidiary of ARRIS.

SECTION 1.4 —Subsequent Actions. If, at any time after the Effective Time, the Surviving Corporation shall consider or be advised that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to continue in, vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties, privileges, franchises or assets of either of its constituent corporations acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, the directors and officers of the Surviving Corporation shall be directed and authorized to execute and deliver, in the name and on behalf of either of such constituent corporations, all such deeds, bills of sale, assignments and assurances and to take and do, in the name and on behalf of each of such corporations or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title and interest in, to and under such rights, properties, privileges, franchises or assets in the Surviving Corporation or otherwise to carry out this Agreement.

SECTION 1.5 —Certificate of Incorporation; Bylaws; Directors and Officers of Surviving Corporation. Unless otherwise agreed by C-COR and ARRIS before the Effective Time, at the Effective Time:

(a) the Certificate of Incorporation of the Merger Subsidiary immediately prior to the Effective Time shall be the Certificate of Incorporation of the Merger Subsidiary as the Surviving Corporation from and after the Effective Time, until thereafter amended as provided by Delaware Law and such Certificate of Incorporation, except that the name of the Merger Subsidiary as the Surviving Corporation shall be changed to “C-COR Incorporated;”

(b) the Bylaws of the Merger Subsidiary immediately prior to the Effective Time shall be the Bylaws of the Merger Subsidiary as the Surviving Corporation from and after the Effective Time, until thereafter amended as provided by Delaware Law, the Certificate of Incorporation and such Bylaws; and

(c) the directors of the Merger Subsidiary immediately prior to the Effective Time shall continue to serve as directors of the Surviving Corporation, and the officers of C-COR immediately prior to the Effective Time shall continue to serve in their respective offices as officers of the Surviving Corporation from and after the Effective Time, in each case until their successors are elected or appointed or until their resignation or removal. If, at the Effective Time, a vacancy shall exist in any office of the Surviving Corporation, such vacancy may thereafter be filled in the manner provided by Delaware Law and the Bylaws of the Merger Subsidiary as the Surviving Corporation.

ARTICLE II

EFFECT ON STOCK OF THE SURVIVING
CORPORATION AND THE MERGED CORPORATION

SECTION 2.1 —Conversion of Securities. The manner and basis of converting the shares of common stock of the Merged Corporation at the Effective Time, by virtue of the Merger and without any action on the part of any of the Parties or the holder of any of such securities, shall be as hereinafter set forth in this Article II.

SECTION 2.2— Conversion of Shares.

(a) Subject to Section 2.3, each share of C-COR Common Stock (as defined herein) issued and outstanding immediately before the Effective Time (excluding those held in the treasury of C-COR and those owned by ARRIS, referred to herein as the “Excluded C-COR Shares”) and all rights in respect thereof, shall at the Effective Time, without any action on the part of any holder thereof, forthwith cease to exist and be converted into and become exchangeable, at the election of the holder thereof: (i) for each share of C-COR Common Stock with respect to which an election to receive cash has been effectively made and not revoked or lost pursuant to Section 2.5 (a “Cash Election”), the right to receive in cash from ARRIS, without interest, an amount equal to $13.75 (the “Cash Consideration”), (collectively, “Cash Election Shares”); (ii) for each share of C-COR Common Stock with respect to which an election to receive ARRIS Common Stock (as defined herein) has been effectively made and not revoked or lost pursuant to Section 2.5 (a “Stock Election”), the right to receive from ARRIS a portion of a share of ARRIS Common Stock equal to 0.9642 of a share, subject to adjustment as set forth in Section 2.2(b) below, (the “Exchange Ratio”) of ARRIS Common Stock (the “Stock Consideration”), subject to adjustment as provided in Section 2.2(b) (collectively, the “Stock Election Shares”); and (iii) for each share of C-COR Common Stock other than shares as to which a Cash Election or a Stock Election has been effectively made and not revoked or lost pursuant to Section 2.5 (“Non-Election Shares”), the right to receive from ARRIS such Stock Consideration and/or Cash Consideration as is determined in accordance with Section 2.3(b). For purposes of this Agreement, the term “Merger Consideration” with respect to a given share of C-COR Common Stock shall mean either the Cash Consideration (with respect to a share of C-COR Common Stock representing the right to receive the Cash Consideration) or the Stock Consideration (with respect to a share of C-COR Common Stock representing the right to receive the Stock Consideration).

(b) In the event that the average closing price of the ARRIS Common Stock on the Nasdaq Global Select Market (as reported inThe Wall Street Journal) for the ten trading-day period ending the third trading day prior to the anticipated Closing Date (the “Average Trading Price”) is less than $12.83 (a “Decrease Event”) then ARRIS shall increase the amount of the Stock Consideration, which increase in the Stock Consideration, at ARRIS’ election by notice to the Exchange Agent and C-COR, may be paid as cash or additional shares of ARRIS Common Stock, such that the value of the aggregate Merger Consideration paid per share of C-COR Common Stock for all outstanding shares of C-COR Common Stock (other than Excluded C-COR Shares), calculated using the Average Trading Price (solely for purposes of determining the value of the shares of ARRIS Common Stock to be issued as Stock Consideration), equals $13.08. If the Average Trading Price is more than $15.69 (an “Increase Event”), then ARRIS shall decrease the amount of the Stock Consideration such that the value of the aggregate Merger Consideration paid per share of C-COR Common Stock for all outstanding shares of C-COR Common Stock (other than Excluded C-COR Shares), calculated using the Average Trading Price (solely for purposes of determining the value of the shares of ARRIS Common Stock to be issued as Stock Consideration), equals $14.43. Notwithstanding the foregoing, in making the adjustments to the Merger Consideration set forth in this Section 2.2(b), (i) ARRIS shall not be required to use an Average Trading Price of less than $11.41 or more than $17.11, and (ii) in the event of a Decrease Event, ARRIS shall not elect to pay such increase in cash to the extent that such increase in cash would result in counsel to C-COR or counsel to ARRIS being unable to deliver its opinion contemplated by Sections 8.2(d) or 8.3(d), respectively.

(c) Commencing immediately after the Effective Time, each certificate that, immediately prior to the Effective Time, represented issued and outstanding shares of C-COR Common Stock (“C-COR Shares”) shall evidence the right to receive the Merger Consideration on the basis hereinbefore set forth, but subject to the limitations set forth in this Article II.

(d) For all purposes of this Agreement, unless otherwise specified, all C-COR Shares held by retirement plans of C-COR subject to the requirements under Section 401(a) of the Code and all C-COR Shares held in non-qualified plans of C-COR (the “C-COR Retirement Plan Shares”) (i) shall be deemed to be issued and outstanding, (ii) shall not be deemed to be held in the treasury of C-COR and (iii) shall be converted into the right to receive the Merger Consideration in accordance with Section 2.2(a);provided,however, that all such C-COR Retirement Plan Shares shall be deemed Non-Election Shares for purposes of this Article II.

SECTION 2.3 —Allocation of Merger Consideration.

(a) Notwithstanding any other provision contained in this Agreement and subject to ARRIS’s rights under Section 2.3(b) to increase the Stock Consideration by adding cash instead of ARRIS Common Stock, (i) the number of shares of C-COR Common Stock to be converted into Stock Consideration pursuant to Section 2.2(a) (the “Stock Conversion Number”) shall be equal to the product obtained by multiplying (A) the number of shares of C-COR Common Stock outstanding immediately prior to the Effective Time by (B) 0.4909 and (ii) all of the other shares of C-COR Common Stock outstanding immediately prior to the Effective Time shall be converted into Cash Consideration (in case of each of clauses (i) and (ii), excluding the Excluded C-COR Shares).

(b) As soon as practicable after the Election Deadline (as defined herein) and in any event no more than five business days after the Closing Date (or such other date as C-COR and ARRIS shall agree), ARRIS shall cause the Exchange Agent to effect the allocation among holders of C-COR Common Stock (other than Excluded C-COR Shares) of rights to receive the Cash Consideration and the Stock Consideration as follows:

(i) If the aggregate number of C-COR Shares with respect to which Stock Elections shall have been made (the “Stock Election Number”) exceeds the Stock Conversion Number, then all Cash Election Shares and all Non-Election Shares of each holder thereof shall be converted into the right to receive the Cash Consideration and Stock Election Shares of each holder thereof will be converted into the right to receive the Stock Consideration in respect of that number of Stock Election Shares of such holder equal to the product obtained by multiplying (A) the number of Stock Election Shares held by such holder by (B) a fraction, the numerator of which is the Stock Conversion Number and the denominator of which is the Stock Election Number, with the remaining number of such holder’s Stock Election Shares being converted into the right to receive the Cash Consideration; and

(ii) If the Stock Election Number is less than the Stock Conversion Number (the amount by which the Stock Conversion Number exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), then all Stock Election Shares shall be converted into the right to receive the Stock Consideration and the Non-Election Shares and Cash Election Shares shall be treated in the following manner: (A) if the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Cash Election Shares shall be converted into the right to receive the Cash Consideration and the Non-Election Shares of each holder thereof shall be converted into the right to receive the Stock Consideration in respect of that number of Non-Election Shares equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares, with the remaining number of such holder’s Non-Election Shares being converted into the right to receive the Cash Consideration; or (B) if the Shortfall Number exceeds the number of Non-Election Shares, then all Non-Election Shares shall be converted into the right to receive the Stock Consideration and Cash Election Shares of each holder thereof shall be converted into the right to receive the Stock Consideration in respect of that number of Cash Election Shares equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which the Shortfall Number exceeds the total number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares, with the remaining number of such holder’s Cash Election Shares being converted into the right to receive the Cash Consideration.

SECTION 2.4 —Cancellation of Treasury Shares. Except as provided in Section 2.2(d), at the Effective Time, each share of C-COR Common Stock held in the treasury of C-COR or owned by ARRIS immediately prior to the Effective Time shall be canceled and retired and no shares of stock or other securities of ARRIS or the Surviving Corporation shall be issuable, and no payment or other consideration shall be made, with respect thereto.

SECTION 2.5 —Election of Merger Consideration and Exchange of Shares. Each holder of record of C-COR Common Stock (other than (i) Excluded C-COR Shares and (ii) C-COR Retirement Plan Shares) shall have the right, subject to the limitations set forth in this Article II to submit an election in accordance with the following procedures:

(a) Each holder may specify in a request made in accordance with the provisions of this Section 2.5 (herein called an “Election”) (i) the number of C-COR Shares owned by such holder with respect to which such holder desires to make a Stock Election and (ii) the number of C-COR Shares owned by such holder with respect to which such holder desires to make a Cash Election.

(b) Subject to the terms and conditions hereof, at or prior to the Effective Time, ARRIS and C-COR shall jointly appoint an exchange agent to effect the exchange of C-COR Shares for the Merger Consideration in accordance with the provisions of this Article II (the “Exchange Agent”). Prior to the Effective Time, ARRIS shall deposit, or cause to be deposited, with the Exchange Agent cash and certificates representing ARRIS Common Stock sufficient to pay all amounts for conversion of C-COR Shares in accordance with the provisions of Section 2.2 hereof, it being understood that any and all interest earned on funds deposited with the Exchange Agent shall be turned over to ARRIS. Commencing immediately after the Effective Time and until the appointment of the Exchange Agent shall be terminated, each holder of a certificate or certificates theretofore representing C-COR Shares may surrender the same to the Exchange Agent, and, after the appointment of the Exchange Agent shall be terminated, any such holder may surrender any such certificate to ARRIS. Each holder shall be entitled upon such surrender to receive in exchange therefor the Cash Consideration and a certificate or certificates representing the number of full shares of the Stock Consideration into which the C-COR Shares theretofore represented by the certificate or certificates so surrendered shall have been converted in accordance with the provisions of Section 2.2 hereof, together with a cash payment in lieu of fractional shares, if any, in accordance with Section 2.7 hereof. All such shares of ARRIS Common Stock issued as Stock Consideration shall be issued at the Effective Time. Until so surrendered and exchanged, each outstanding certificate that, prior to the Effective Time, represented issued and outstanding C-COR Shares shall be for all corporate purposes of ARRIS, other than the payment of dividends and other distributions, if any, to evidence the right to receive the Merger Consideration. Unless and until any such certificate theretofore representing C-COR Shares is so surrendered, no dividend or other distribution, if any, payable to the holders of record of ARRIS Common Stock as of any date subsequent to the Effective Time shall be paid to the holder of such certificate in respect thereof. Except as otherwise provided in Section 2.6 hereof, upon the surrender of any such certificate theretofore representing C-COR Shares, however, the record holder of the certificate or certificates representing shares of ARRIS Common Stock issued in exchange therefor shall receive from the Exchange Agent or from ARRIS, as the case may be, payment of the amount of dividends and other distributions, if any, that as of any date subsequent to the Effective Time and until such surrender shall have become payable with respect to such number of shares of ARRIS Common Stock (“Pre-Surrender Dividends”). No interest shall be payable with respect to the payment of Pre-Surrender Dividends upon the surrender of certificates theretofore representing C-COR Shares. After the appointment of the Exchange Agent shall have been terminated, any holders of certificates representing C-COR Shares which have not received payment of Pre-Surrender Dividends shall look only to ARRIS for payment thereof. Notwithstanding the foregoing provisions of this

Section 2.5(b), neither the Exchange Agent nor any Party shall be liable to a holder of C-COR Shares for any Cash Consideration, Stock Consideration, any dividends or distributions thereon or any cash payment for fractional shares as contemplated by Section 2.7, delivered to a public official pursuant to any applicable abandoned property, escheat or similar law or to a transferee.

(c) ARRIS shall cause the Exchange Agent to mail to the shareholders of C-COR entitled to vote at the C-COR Stockholders’ Meeting (as defined herein), at the time that the Joint Proxy Statement (as defined herein) is provided to the stockholders of C-COR, a form reasonably acceptable to C-COR (the “Form of Election”) pursuant to which C-COR’s stockholders shall be entitled to exercise their right to make an Election prior to the Election Deadline (as defined herein), and shall cause the Exchange Agent to use all reasonable efforts to make available as promptly as possible a Form of Election to any stockholder of C-COR who requests such Form of Election following the initial mailing of the Form of Election and prior to the Election Deadline. In no event shall the initial mailing of the Form of Election to C-COR’s stockholders be made less than 20 days prior to the Election Deadline.

(d) Any Election shall have been made properly only if the person authorized to receive Elections and to act as Exchange Agent under this Agreement, shall have received, by 5:00 p.m. New York City time on the date of the Election Deadline, a Form of Election properly completed and signed. As used herein, “Election Deadline” means 5:00 p.m. New York City time on the date that is the business day prior to the date of the C-COR Stockholders Meeting (or at such other date and time as C-COR and ARRIS shall agree). ARRIS and C-COR shall cooperate to issue a press release announcing the date of the Election Deadline not more than fifteen business days before, and at least five business days prior to, the Election Deadline (and, if C-COR and ARRIS shall agree to any extension thereof, C-COR and ARRIS shall make a public announcement of any such extension as far as reasonably practicable prior to such new Election Deadline).

(e) If ARRIS shall determine in its reasonable discretion that any Election is not properly made with respect to any C-COR Shares, such Election shall be deemed to be not in effect, thereafter timely filed. Any stockholder of C-COR may, at any time prior to the Election Deadline, change his, her or its Election by written notice received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed, revised Form of Election. Any stockholder of C-COR may, at any time prior to the Election Deadline, revoke his, her or its Election by written notice received by the Exchange Agent prior to the Election Deadline.

(f) Each of the Exchange Agent, ARRIS and the Surviving Corporation will be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any holder of shares of C-COR Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any other applicable state, local or foreign law related to Taxes. To the extent that amounts are so withheld by the Surviving Corporation or ARRIS, as the case may be, such withheld amounts (i) will be remitted by ARRIS or the Surviving Corporation, as the case may be, to the applicable governmental entity, and (ii) will be treated for all purposes of this Agreement as having been paid to the holder of the share of C-COR Common Stock in respect of which such deduction and withholding was made by the Surviving Corporation or ARRIS, as the case may be.

(g) If any certificate formerly representing C-COR Shares 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 ARRIS, the posting by such person of a bond, in such reasonable amount as ARRIS may direct, as indemnity against any claim that may be made against it with respect to such certificate, the Exchange Agent shall pay, in exchange for such lost, stolen or destroyed certificate, the Merger Consideration to be paid in respect of C-COR Shares represented by such certificate, as contemplated by this Section 2.5.

SECTION 2.6 —Transfer Books. The stock transfer books of C-COR shall be closed at the Effective Time and no transfer of any C-COR Shares will thereafter be recorded on any of such stock transfer books. In the event of a transfer of ownership of C-COR Shares that is not registered in the stock transfer records of C-COR at the Effective Time, cash and a certificate or certificates representing the number of full shares of ARRIS Common Stock into which such C-COR Shares shall have been converted shall be issued to the transferee together with a cash payment in lieu of fractional shares, if any, in accordance with Section 2.7 hereof, and a cash payment in the amount of Pre-Surrender Dividends, if any, in accordance with Section 2.5(b) hereof, if the certificate or certificates representing such C-COR Shares is or are surrendered as provided in Section 2.5 hereof, accompanied by all documents required to evidence and effect such transfer and by evidence of payment of any applicable stock transfer tax.

SECTION 2.7 —No Fractional Share Certificates. Notwithstanding any other provision of this Agreement, each holder of shares of C-COR Common Stock exchanged pursuant to the Merger who otherwise would have been entitled to receive a fraction of a share of ARRIS Common Stock (after taking into account all certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of ARRIS Common Stock multiplied by the Average Trading Price. No such holder will be entitled to dividends, voting rights, or any other rights as a stockholder in respect of any fractional shares.

SECTION 2.8 —Options to Purchase C-COR Common Stock.

(a) At the Effective Time, each option granted by C-COR to purchase shares of C-COR Common Stock that is outstanding and unexercised immediately prior to the Effective Time (the “Assumed Equity Awards”), whether vested or unvested, shall be assumed by ARRIS and converted into an option or warrant to purchase shares of ARRIS Common Stock in such amount and at such exercise price as provided below and otherwise having the same terms, conditions and restrictions as are in effect immediately prior to the Effective Time (except to the extent that such terms, conditions and restrictions may be altered in accordance with their terms as a result of the transactions contemplated hereby):

(i) the number of shares of ARRIS Common Stock to be subject to the new option or warrant shall be equal to the product of (x) the number of shares of C-COR Common Stock subject to the original option or warrant multiplied by (y) 0.9642 (the “Option Exchange Ratio”), rounded down to the nearest whole share;provided,however, that (A) in the event of a Decrease Event under Section 2.2(b), the Option Exchange Ratio shall be the quotient obtained by dividing $13.08 by the Average Trading Price, and (B) in the event of an Increase Event under Section 2.2(b), the Option Exchange

Ratio shall be the quotient obtained by dividing $14.43 by the Average Trading Price, in the case of either (A) or (B), rounded down to the nearest whole share;provided,further, that ARRIS shall not be required to use an Average Trading Price of less than $11.41 or more than $17.11; and

(ii) the exercise price per share of ARRIS Common Stock under the new option or warrant shall be equal to the result of (x) the exercise price per share of the C-COR Common Stock under the original option or warrant divided by (y) the applicable Option Exchange Ratio, rounded up to the nearest cent.

(b) For purposes of Section 4(b) of the C-COR Amended and Restated Incentive Plan (the “Incentive Plan”), the provisions of Section 2.8(a) constitute an adjustment in the number and option price of shares subject to, and the consideration to be issued upon the exercise of, outstanding Options (as defined in the Incentive Plan), as determined appropriate by the Board of Directors of C-COR, as of the Effective Time, and no further action or amendment of the Incentive Plan shall be necessary to implement such adjustment.

(c) The adjustments provided herein shall, to the extent applicable, be effected in a manner consistent with Section 409A of the Code so as not to be treated as new grants or awards or as a change in the form of payment, and with respect to any options that are “incentive stock options” (as defined in Section 422 of the Code) shall be effected in a manner consistent with Section 424(a) of the Code.

(d) ARRIS shall take all corporate actions necessary to reserve for issuance a sufficient number of shares of ARRIS Common Stock for delivery upon exercise of the Assumed Equity Awards assumed in accordance with this Section 2.8. Within ten (10) business days following the Effective Time, ARRIS shall file a registration statement on Form S-8 (or any successor form) with respect to ARRIS Common Stock subject to such Assumed Equity Awards and shall use its reasonable best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such Assumed Equity Awards remain outstanding.

(e) As of the Effective Time, ARRIS shall assume the obligations and succeed to the rights of C-COR under the Incentive Plan with respect to the Assumed Equity Awards.

(f) At the Effective Time, each warrant granted by C-COR to purchase shares of C-COR Common Stock that is outstanding and unexercised immediately prior to the Effective Time, whether vested or unvested, shall be canceled and no shares of stock or other securities of ARRIS or the Surviving Corporation shall be issuable, and no payment or other consideration shall be made with respect thereto. C-COR will take all steps reasonably necessary to notify the holders of such warrants of the anticipated Effective Time as required by the applicable warrant agreements.

SECTION 2.9 —Restricted Stock. At the Effective Time, each share of C-COR Common Stock awarded pursuant to any plan, arrangement or transaction, and outstanding immediately prior to the Effective Time shall be treated as fully vested and shall be exchanged in accordance with Section 2.2 hereof with respect to such percentage of such award equal to the

percentage of the applicable restriction period for such award that has elapsed as of the Effective Time.

SECTION 2.10 —Certain Adjustments. If between the date hereof and the Effective Time, the outstanding shares of C-COR Common Stock or of ARRIS Common Stock shall be changed into a different number of shares by reason of any reclassification, recapitalization, split-up, combination or exchange of shares, or any dividend payable in stock or other securities shall be declared thereon with a record date within such period, the Exchange Ratio and Option Exchange Ratio shall be adjusted accordingly to provide to the holders of C-COR Common Stock and ARRIS Common Stock the same economic effect as contemplated by this Agreement prior to such reclassification, recapitalization, split-up, combination, exchange or dividend.

C-COR and its Subsidiaries are in compliance with the terms of the C-COR Permits, except where the failure to so comply would not have a Material Adverse Effect.

SECTION 4.7 —SEC Filings; Financial Statements.

(a) C-COR has filed all forms, reports and documents required to be filed with the SEC and has made available to ARRIS (i) its Annual Reports on Form 10-K for the fiscal years

ended June 24, 2005, June 30, 2006 and June 29, 2007, (ii) all proxy statements relating to C-COR’s meetings of stockholders (whether annual or special) held since June 25, 2004, (iii) all other reports or registration statements filed by C-COR with the Securities and Exchange Commission (the “SEC”) since June 25, 2004, and (iv) all amendments and supplements to all such reports and registration statements filed by C-COR with the SEC since June 25, 2004 (collectively, the “C-COR SEC Reports”). Except as disclosed in Section 4.7(a) of the C-COR Disclosure Schedule, the C-COR SEC Reports (i) were prepared in all material respects in accordance with the requirements of the 1933 Act (as defined herein) or the Exchange Act, as the case may be, and (ii) did not at the time they were filed (or if amended or superseded by a filing prior to the date of this Agreement, then on the date of such filing) contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. None of C-COR’s Subsidiaries is required to file any forms, reports or other documents with the SEC.

(b) Except as disclosed in Section 4.7(b) of the C-COR Disclosure Schedule, each of the consolidated financial statements (including, in each case, any related notes thereto) contained in the C-COR SEC Reports was prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto), and each fairly presents in all material respects the consolidated financial position of C-COR and its Subsidiaries as at the respective dates thereof and the consolidated results of its operations and cash flows for the periods indicated, except that the unaudited interim financial statements were subject to normal and recurring year-end adjustments which were not, or are not expected to be, material in amount.

(c) C-COR has established and maintains “disclosure controls and procedures” (as defined in Rule 13a-15(e) promulgated under the Exchange Act) that are reasonably designed to ensure that material information (both financial and non-financial) relating to C-COR and its Subsidiaries required to be disclosed by C-COR in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to C-COR’s principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding disclosure and to make the certifications of the principal executive officer and the principal financial officer of C-COR required by Section 302 of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”) with respect to such reports. For purposes of this Agreement, “principal executive officer” and “principal financial officer” shall have the meanings given to such terms in Sarbanes-Oxley.

(d) C-COR has established and maintains a “system of internal control over financial reporting” (as defined in Rule 13a-15(f) promulgated under the Exchange Act) (“internal controls”). Such internal controls are sufficient to provide reasonable assurance regarding the reliability of C-COR’s financial reporting and the preparation of C-COR’s financial statements for external purposes in accordance with GAAP (as defined herein). C-COR has disclosed, based on its most recent evaluation of internal controls prior to the date hereof, to C-COR’s auditors and audit committee (i) any significant deficiencies and material weaknesses known to C-COR in the design or operation of internal controls which are reasonably likely to adversely affect in a material respect C-COR’s ability to record, process, summarize and report financial information

and (ii) any material fraud known to C-COR that involves management or other employees who have a significant role in internal controls. C-COR has made available to ARRIS a summary of any such disclosure regarding material weaknesses and fraud made by management to C-COR’s auditors and audit committee since July 1, 2005. For purposes of this Agreement, a “significant deficiency” in controls means an internal control deficiency that adversely affects an entity’s ability to initiate, authorize, record, process, or report external financial data reliably in accordance with GAAP. A “significant deficiency” may be a single deficiency or a combination of deficiencies that results in more than a remote likelihood that a misstatement of the annual or interim financial statements that is more than inconsequential will not be prevented or detected. For purposes of this Agreement, a “material weakness” in internal controls means a significant deficiency, or a combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.

SECTION 4.8 —Absence of Certain Changes or Events.

SECTION 4.9 —No Undisclosed Liabilities. Except as is disclosed in Section 4.9 of the C-COR Disclosure Schedule, neither C-COR nor any of its Subsidiaries has any liabilities (absolute, accrued, contingent or otherwise), except liabilities (a) in the aggregate adequately provided for in C-COR’s audited balance sheet (including any related notes thereto) as of June 29, 2007 (the “2007 C-COR Balance Sheet”), (b) incurred in the ordinary course of business and not required under GAAP to be reflected on the 2007 C-COR Balance Sheet, (c) incurred since June 29, 2007, in the ordinary course of business consistent with past practice, or (d) incurred in connection with this Agreement.

SECTION 4.10 —Absence of Litigation. Except as set forth in Section 4.10 of the C-COR Disclosure Schedule, there are no claims, actions, suits or proceedings pending or, to the knowledge of C-COR, overtly threatened and to the knowledge of C-COR, there are no investigations pending or threatened against C-COR or any of its Subsidiaries, or any properties or rights of C-COR or any of its Subsidiaries, before any court, arbitrator or administrative, governmental or regulatory authority or body, domestic or foreign, could reasonably be expected to result in a liability in excess of $500,000.

SECTION 4.11 —Joint Proxy Statement. None of the information supplied or to be supplied by or on behalf of C-COR for inclusion or incorporation by reference in the registration

statement to be filed with the SEC by ARRIS in connection with the issuance of shares of ARRIS Common Stock in the Merger (the “Registration Statement”) will, at the time the Registration Statement becomes effective under the 1933 Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. None of the information supplied or to be supplied by or on behalf of C-COR for inclusion or incorporation by reference in the joint proxy statement, in definitive form, relating to the meetings of C-COR and ARRIS stockholders to be held in connection with the Merger, or in the related proxy and notice of meeting, or soliciting material used in connection therewith (referred to herein collectively as the “Joint Proxy Statement”) will, at the dates mailed to stockholders and at the times of the C-COR Stockholders’ Meeting and the ARRIS Stockholders’ Meeting (as defined herein), contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

Except under valid and binding confidentiality obligations, there has been no material disclosure by C-COR or any of its Subsidiaries to a third party of any confidential information or trade secrets used in connection with the conduct of C-COR’s business.

(m) C-COR and its Subsidiaries have valid registrations for each of the domain names set forth in Section 4.21(a) of the C-COR Disclosure Schedule.

compiled from the associated source code in accordance with the means currently employed by C-COR. Except for any components of the source code licensed in from third parties, C-COR has actual and sole possession of the complete source code of C-COR Software. Except as set forth on Section 4.21(n) of the C-COR Disclosure Schedule, other than C-COR’s or any of its Subsidiaries’ delivery of C-COR source code to third party escrow agents or their disclosure of such source code to third parties as part of a software development kit made available by C-COR or any of its Subsidiaries in the ordinary course of business, no event has occurred, and to the knowledge of C-COR no circumstance or condition exists, that (with or without notice or lapse of time) will, or could reasonably be expected to, result in the disclosure or delivery to any third party of the source code for C-COR Software. C-COR Software (as used or distributed by C-COR or its Subsidiaries) does not contain any “back door,” “time bomb,” “Trojan horse,” “worm,” “drop dead device,” “virus” (as these terms are commonly used in the computer software industry), or other Software routines or hardware components intentionally designed to permit unauthorized access, to disrupt, disable or erase software, hardware or data, or to perform any other similar type of unauthorized activities.

(o) Except as set forth in Section 4.21(o) of the C-COR Disclosure Schedule, none of C-COR Software or any Owned Intellectual Property are, in whole or in part, subject to the provision of any open source or other similar type of license agreement or distribution model that (i) requires the distribution or making available of the source code for C-COR Software to the general public, (ii) prohibits or limits C-COR or any of its Subsidiaries from charging a fee or receiving consideration in connection with sublicensing or distributing any C-COR Software, (iii) except as specifically permitted by law, grants any right to any third party (other than C-COR and its Subsidiaries) or otherwise allows any such third party to decompile, disassemble or otherwise reverse-engineer any C-COR Software, or (iv) requires the licensing of any C-COR Software to the general public for the purpose of permitting others to make derivative works of C-COR Software (any such open source or other type of license agreement or distribution model described in clause (i), (ii), (iii) or (iv) above, a “Limited License”). By way of clarification, but not limitation, the term “Limited License” includes (A) GNU’s General Public License (GPL) or Lesser/Library GPL (LGPL), (B) the Artistic License (e.g., PERL), (C) the Mozilla Public License, (D) the Netscape Public License, (E) the Sun Community Source License (SCSL), and (F) the Sun Industry Standards License (SISL). To the knowledge of C-COR, none of C-COR Software incorporates, or is distributed with, any Software that is subject to a Limited License, nor does any C-COR Software constitute a derivative work of or dynamically link with any such Software.

(p) Except as set forth on Section 4.21(p) of the C-COR Disclosure Schedule, no government funding, facilities of a university, college, or other educational institution or research center was used in the creation or development of the Owned Intellectual Property or C-COR Software.

SECTION 5.5 —No Conflict, Required Filings and Consents.

(a) Section 5.5(a) of the ARRIS Disclosure Schedule includes a list of all agreements to which ARRIS or any of its Subsidiaries is a party or by which any of them is bound that, as of the date hereof are required to be filed as “material contracts” with the SEC pursuant to the requirements of the Exchange Act (collectively, the “ARRIS Material Contracts”).

(b) Except as set forth in Section 5.5(b) of the ARRIS Disclosure Schedule, the execution and delivery of this Agreement by ARRIS does not, and the performance of this Agreement by ARRIS will not, (i) conflict with or violate the Certificate of Incorporation, By-laws or Subsidiary Documents of ARRIS or any of its Subsidiaries, (ii) conflict with or violate any law, rule, regulation, order, judgment or decree applicable to ARRIS or any of its Subsidiaries or by which its or their respective properties are bound or affected, or (iii) result in any breach of or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or impair ARRIS’ or any of its Subsidiaries’ rights or alter the rights or obligations of any third party under, or give to others any rights of termination, amendment, acceleration or cancellation of any ARRIS Material Contract, or result in the creation of a lien or encumbrance on any of the properties or assets of ARRIS or any of its Subsidiaries pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which ARRIS or any of its Subsidiaries is a party or by which ARRIS or any of its Subsidiaries or its or any of their respective properties are bound or affected, except in any such case for any such conflicts, violations, breaches, defaults, liens or other occurrences with respect to (ii) and (iii) above that would not have a Material Adverse Effect.

(a) Except as disclosed in Section 5.6(a) of the ARRIS Disclosure Schedule, neither ARRIS nor any of its Subsidiaries is in conflict with, or in default or violation of, (i) any law, rule, regulation, order, judgment or decree applicable to ARRIS or any of its Subsidiaries or by which its or any of their respective properties is bound or affected or (ii) any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or any other instrument or obligation to which ARRIS or any of its Subsidiaries is a party or by which ARRIS or any of its Subsidiaries or its or any of their respective properties is bound or affected, except for any such conflicts, defaults or violations that would not have a Material Adverse Effect.

ARRIS and its Subsidiaries are in compliance with the terms of the ARRIS Permits, except where the failure to so comply would not have a Material Adverse Effect.

SECTION 5.7 —SEC Filings; Financial Statements.

(a) ARRIS has filed all forms, reports and documents required to be filed with the SEC and has made available to C-COR (i) its Annual Reports on Form 10-K for the fiscal years ended December 31, 2004, 2005 and 2006, respectively, (ii) its Quarterly Reports on Form 10-Q for the periods ended September 30, 2006, March 31, 2007 and June 30, 2007 (iii) all proxy statements relating to ARRIS’ meetings of stockholders (whether annual or special) held since January 1, 2004, (iv) all other reports or registration statements (other than Reports on Form 10-Q not referred to in clause (ii) above) filed by ARRIS with the SEC since January 1, 2004, and (v) all amendments and supplements to all such reports and registration statements filed by ARRIS with the SEC since January 1, 2004 (collectively, the “ARRIS SEC Reports”). Except as disclosed in Section 5.7 of the ARRIS Disclosure Schedule, the ARRIS SEC Reports (i) were prepared in all material respects in accordance with the requirements of the 1933 Act or the Exchange Act, as the case may be, and (ii) did not at the time they were filed (or if amended or superseded by a filing prior to the date of this Agreement, then on the date of such filing) contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. None of the ARRIS’ Subsidiaries is required to file any forms, reports or other documents with the SEC.

(b) Each of the consolidated financial statements (including, in each case, any related notes thereto) contained in the ARRIS SEC Reports was prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto), and each fairly presents in all material respects the consolidated financial position of ARRIS and its Subsidiaries as at the respective dates thereof and the consolidated results of its operations and cash flows for the periods indicated, except that the unaudited interim financial

statements were or are subject to normal and recurring year-end adjustments which were not. or are not expected to be, material in amount.

(c) ARRIS has established and maintains “disclosure controls and procedures” (as defined in Rule 13a-15(e) promulgated under the Exchange Act) that are reasonably designed to ensure that material information (both financial and non-financial) relating to ARRIS and its Subsidiaries required to be disclosed by ARRIS in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to ARRIS’ principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding disclosure and to make the certifications of the principal executive officer and the principal financial officer of ARRIS required by Sarbanes-Oxley with respect to such reports. For purposes of this Agreement, “principal executive officer” and “principal financial officer” shall have the meanings given to such terms in Sarbanes-Oxley.

(d) ARRIS has established and maintains a “system of internal control over financial reporting” (as defined in Rule 13a-15(f) promulgated under the Exchange Act) (“internal controls”). Such internal controls are sufficient to provide reasonable assurance regarding the reliability of ARRIS’ financial reporting and the preparation of ARRIS’ financial statements for external purposes in accordance with GAAP. ARRIS has disclosed, based on its most recent evaluation of internal controls prior to the date hereof, to ARRIS’ auditors and audit committee (i) any significant deficiencies and material weaknesses known to ARRIS in the design or operation of internal controls which are reasonably likely to adversely affect in a material respect ARRIS’ ability to record, process, summarize and report financial information and (ii) any material fraud known to ARRIS that involves management or other employees who have a significant role in internal controls. ARRIS has made available to C-COR a summary of any such disclosure regarding material weaknesses and fraud made by management to ARRIS’ auditors and audit committee since December 31, 2004. For purposes of this Agreement, a “significant deficiency” in controls means an internal control deficiency that adversely affects an entity’s ability to initiate, authorize, record, process, or report external financial data reliably in accordance with GAAP. A “significant deficiency” may be a single deficiency or a combination of deficiencies that results in more than a remote likelihood that a misstatement of the annual or interim financial statements that is more than inconsequential will not be prevented or detected. For purposes of this Agreement, a “material weakness” in internal controls means a significant deficiency, or a combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.

SECTION 5.11 —Joint Proxy Statement. None of the information supplied or to be supplied by or on behalf of ARRIS for inclusion or incorporation by reference in the Registration Statement will, at the time the Registration Statement becomes effective under the 1933 Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. None of the information supplied or to be supplied by or on behalf of ARRIS for inclusion or incorporation by reference in the Joint Proxy Statement, will, at the dates mailed to stockholders and at the times of the C-COR Stockholders’ Meeting and the ARRIS Stockholders’ Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading. The information provided by ARRIS for the Registration Statement and the Joint Proxy Statement (except for information relating solely to C-COR) will comply as to form in all material respects with the provisions of the 1933 Act and the Exchange Act and the rules and regulations promulgated thereunder.

SECTION 5.12 —Employee Benefit Plans, Employment Agreements.

(j) ARRIS and its Subsidiaries have valid registrations for each of the domain names owned by ARRIS. The registration of each such domain name is free and clear of all liens and is

in full force and effect. ARRIS has paid all fees required to maintain each such registration. Neither ARRIS nor any of its Subsidiaries has received written notice of any claim asserted against ARRIS or any of its Subsidiaries adverse to its rights to such domain names, and, to the knowledge of ARRIS, none of ARRIS’ registrations or uses of the domain names has been disturbed or placed “on hold.”

(k) To the knowledge of ARRIS, all ARRIS Software is free from any material defect or programming or documentation error, including major bugs, logic errors or failures of such software to operate in all material respects as described in the related documentation, and substantially conforms to the specifications of such software, other than those defects, errors, bugs or failures that would not have a Material Adverse Effect on ARRIS.

(l) Except as set forth in Section 5.16(l) of the ARRIS Disclosure Schedule, none of the ARRIS Software or any ARRIS Owned Intellectual Property are, in whole or in part, subject to the provision of any open source or other similar type of license agreement or distribution model that (i) requires the distribution or making available of the source code for ARRIS Software to the general public, (ii) prohibits or limits ARRIS or any of its Subsidiaries from charging a fee or receiving consideration in connection with sublicensing or distributing any ARRIS Software, (iii) except as specifically permitted by law, grants any right to any third party (other than ARRIS and its Subsidiaries) or otherwise allows any such third party to decompile, disassemble or otherwise reverse-engineer any ARRIS Software, or (iv) requires the licensing of any ARRIS Software to the general public for the purpose of permitting others to make derivative works of ARRIS Software.

SECTION 5.19 —Brokers. No broker, finder or investment banker (other than UBS Securities LLC) is entitled to any brokerage, finder’s or other fee or commission in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of ARRIS.

certificates separate from the certificates representing the shares of ARRIS Common Stock and (b) the rights becoming exercisable under the ARRIS Rights Agreement.

SECTION 6.2 —No Solicitation by C-COR.

(a) C-COR shall not, nor shall it permit or authorize any of its Subsidiaries or any officer, director, employee, accountant, counsel, financial advisor, agent or other representative of C-COR or any of its Subsidiaries (collectively, the “C-COR Representatives”) to, on its or any of its Subsidiaries’ behalf, directly or indirectly,

(ii) participate in any discussions or negotiations, furnish to any person any information or data relating to C-COR or its Subsidiaries, provide access to any of the properties, books, records or employees of C-COR or its Subsidiaries or take any other action, in each such case regarding or to facilitate the making of any proposal that constitutes, or may reasonably be expected to lead to, any Takeover Proposal,

(iii) enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other similar agreement or commitment with respect to any Takeover Proposal (an “Alternative Acquisition Agreement”) or agree to, approve, endorse or resolve to recommend or approve any Takeover Proposal, except in each case as otherwise specifically provided in Section 6.2(b),

(iv) grant any waiver or release under any standstill or similar agreement by any third party who has made a Takeover Proposal,

(v) take any action to exempt any third party from the restrictions on “business combinations” contained in Subchapters “C” through “J” of Chapter 25 of Pennsylvania Law or otherwise cause such restrictions not to apply, or

(vi) authorize or direct any C-COR Representative to take any such action;

provided,however, that nothing contained in this Section 6.2(a) or any other provision of this Agreement shall prohibit C-COR or the Board of Directors of C-COR from (A) taking and disclosing to C-COR’s stockholders a position required by Rules 14d-9 and 14e-2 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act, (B) making such disclosure to C-COR’s stockholders as, in the good faith judgment of the Board of Directors of C-COR, after receiving advice from its outside counsel and its financial advisors, C-COR is required under Pennsylvania Law in order to comply with its fiduciary duties, or (C) notifying any third party solely of the existence of, and restrictions under, the provisions of this Section 6.2, provided that C-COR may not, except as permitted by Section 6.2(b), withdraw or modify, or propose to withdraw or modify, its approval or recommendation of this Agreement or the transactions contemplated hereby, including the Merger, or approve or recommend, or propose to approve or recommend, any Takeover Proposal, or enter into any Alternative Acquisition Agreement. Upon execution of this Agreement, C-COR shall, and it shall cause C-COR Representatives and its Subsidiaries to, immediately terminate any existing activities, discussions, solicitations or negotiations with any third party conducted previously with respect to any Takeover Proposal and, if requested by ARRIS, to request the return and/or destruction of any materials previously provided in connection with any such activities, discussions, solicitations or negotiations.

Notwithstanding any of the foregoing restrictions set forth in Section 6.1 or this Section 6.2(a), nothing in this Agreement prevents C-COR or the Board of Directors of C-COR from furnishing (or causing to be furnished), prior to, but not after, the time the vote is taken with

respect to adoption of this Agreement and approval of the Merger at the Meeting of the stockholders of C-COR, information concerning its business, properties or assets to any third party pursuant to a confidentiality agreement with terms and conditions substantially similar to those of the Confidentiality Agreement (as defined herein), so long as such information is contemporaneously provided to ARRIS, and may negotiate and participate in discussions and negotiations with such third party who has made a bona fide, written Takeover Proposal,but only if: (w) such Takeover Proposal was made after the date of this Agreement (it being understood that such a Takeover Proposal made after the date of this Agreement by a third party who has made a Takeover Proposal prior to the date of this Agreement is considered a new Takeover Proposal made after the date of this Agreement); (x) none of C-COR, its Subsidiaries nor the C-COR Representatives has solicited, initiated, or knowingly facilitated or encouraged any Takeover Proposal, or otherwise directly or indirectly violated this Section 6.2 (other than unintentional breaches that (1) have not directly or indirectly resulted in the making of such Takeover Proposal and (2) otherwise have had only an immaterial impact on ARRIS’ rights under this Section 6.2); (y) such third party has submitted a Takeover Proposal that the Board of Directors of C-COR has determined, after receiving advice from its outside legal counsel and its financial advisors, either (i) constitutes a Superior Proposal (as defined below) or (ii) is reasonably likely to lead to a Superior Proposal; and (z) the Board of Directors of C-COR determines in good faith, after receiving advice from its outside counsel and its financial advisors, that such action is required to discharge the Board of Directors of C-COR’s fiduciary duties to C-COR’s stockholders under Pennsylvania Law. C-COR shall not release or permit the release of any third party from, or waive or permit the waiver of any provision of, any confidentiality, standstill (other than to permit the making of a Takeover Proposal) or similar agreement to which C-COR is a party or under which C-COR has any rights. C-COR shall promptly (and in any event within one business day) notify ARRIS telephonically and in writing of the existence of any proposal, discussion, negotiation or inquiry received by C-COR that is or could reasonably be expected to constitute or lead to a Takeover Proposal, and C-COR shall promptly communicate in writing to ARRIS the terms and conditions of any such proposal, discussion, negotiation or inquiry which it may receive, and provide a copy of any written proposal (to the extent permissible by the terms thereof) and the identity of the third party making the same. C-COR shall inform ARRIS within one business day after any change to the material terms of any such Takeover Proposal. Within one business day after any determination by the C-COR Board that a Takeover Proposal constitutes a Superior Proposal, C-COR shall deliver to ARRIS and Merger Subsidiary a written notice advising them of such determination, specifying the terms and conditions of such Superior Proposal and the identity of the third party making such Superior Proposal, and providing ARRIS and Merger Subsidiary with a copy of the Superior Proposal to the extent permissible by the terms thereof.

(b) Neither the Board of Directors of C-COR nor any committee thereof shall (i) withdraw or modify, or propose to withdraw or modify, in a manner adverse to ARRIS or Merger Subsidiary, the recommendation of the Board of Directors of C-COR, (ii) approve or recommend, or propose to approve or recommend, any Takeover Proposal or (iii) enter into any Alternative Acquisition Agreement (other than a confidentiality agreement expressly permitted by and in accordance with Section 6.2(a)). Notwithstanding the foregoing, prior to, but not after, the time the vote is taken with respect to the adoption of this Agreement and approval of the Merger at the Meeting of the stockholders of C-COR, the Board of Directors of C-COR may make a Change in C-COR Recommendation in a manner adverse to ARRIS or Merger

Subsidiary (including, for such purpose, a withdrawal of such recommendation by the Board of Directors of C-COR) (a “Change in C-COR Recommendation”) and/or approve or recommend a Superior Proposal (and, in connection therewith, take such action as shall be necessary to exempt such Superior Proposal from any Takeover Statute (as defined herein) and the C-COR Rights Agreement), and C-COR may enter into an Alternative Acquisition Agreement with respect to a Superior Proposal in connection with the termination of this Agreement, in each case if (A) C-COR has received a Superior Proposal that is pending at the time C-COR determines to take such action, (B) the C-COR Board has determined in good faith, after receiving advice from its outside counsel and its financial advisors, that such action is required to discharge the fiduciary duties of the Board of Directors of C-COR to C-COR’s stockholders under Pennsylvania Law and (C) at least three business days have passed following ARRIS’ receipt of an Adverse Recommendation Notice (as defined below), and ARRIS does not make an offer within such three business day period that is at least as favorable to C-COR’s stockholders as the Superior Proposal, as concluded by the Board of Directors of C-COR in its good faith judgment, after receiving advice from its outside counsel and its financial advisors (it being agreed that the Board of Directors of C-COR shall convene a meeting to consider any such offer by ARRIS as promptly as possible following receipt of such offer and that the Board of Directors of C-COR shall not withhold, withdraw or modify the recommendation of the Board of Directors of C-COR until the earlier of the receipt of ARRIS’ revised offer or three business days after receipt by ARRIS of the Adverse Recommendation Notice).

(i) The term “Adverse Recommendation Notice” means a written notice from C-COR advising ARRIS that the Board of Directors of C-COR has received a Superior Proposal that it intends to accept or recommend or advising ARRIS that it intends to make a Change in C-COR Recommendation, specifying the material terms and conditions of such Superior Proposal and the other information required by Section 6.2(a);provided,however, any material amendment to the financial terms or other material terms of such Superior Proposal shall require a new Adverse Recommendation Notice and a new three business day period pursuant to Section 6.2(b) hereof.

(ii) The term “Competing Transaction” means any transaction, other than the transactions contemplated by this Agreement, to acquire beneficial ownership (as defined under Rule 13(d) promulgated under the Exchange Act) of (A) assets that constitute 20% or more of the consolidated revenues, net income or assets of C-COR and its Subsidiaries or (B) 20% or more (in number or voting power) of any class of equity securities or other capital stock of C-COR or any of its Subsidiaries, in any such case pursuant to any transaction or series of transactions, including (I) a merger, consolidation, share exchange, or other business combination (including any so-called merger-of-equals and whether or not C-COR is the entity surviving any such transaction) involving C-COR or any of its Subsidiaries, (II) a sale, issuance, exchange, transfer or other disposition of shares of capital stock of C-COR or any of its Subsidiaries, (III) a sale, lease, license, exchange, transfer or other disposition of assets of C-COR or any of its Subsidiaries or (IV) a tender offer, exchange offer or similar transaction with

respect to either C-COR or any of its Subsidiaries, including any single or multi-step transaction or series of related transactions, which is structured to permit such third party or another third party to acquire beneficial ownership of assets that constitute 20% or more of the consolidated revenues, net income or assets of C-COR and its Subsidiaries, or 20% or more of the equity interest in either C-COR or any of its Subsidiaries.

(iii) The term “Superior Proposal” means an unsolicited written proposal or offer (whether a Takeover Proposal or otherwise) by a third party to acquire (whether by way of merger, acquisition or otherwise), directly or indirectly, greater than 50% of the shares of C-COR Common Stock then outstanding (or the effect of which would be that the stockholders of C-COR beneficially own less than 50% of the voting power of the combined or ongoing entity), or to acquire all or substantially all of the assets of C-COR and (A) otherwise on terms which the Board of Directors of C-COR determines in good faith, after consultation with its financial advisors, and taking into account all terms and conditions of the proposal or offer that it deems relevant (including all legal, financial, regulatory and other aspects, including any financing condition and time to consummation), to be more favorable to C-COR’s stockholders from a financial point of view than the Merger, and (B) that, in the good faith reasonable judgment of the Board of Directors of C-COR, is reasonably likely to be consummated.

(iv) The term “Takeover Proposal” means any inquiry, proposal, offer or indication of interest (including any inquiry, proposal, offer or indication of interest to its stockholders), whether in writing or otherwise, from a third party that constitutes, or could reasonably be expected to lead to, a Competing Transaction.

SECTION 6.3 —Conduct of Business by ARRIS Pending the Merger. ARRIS covenants and agrees that, except as contemplated by this Agreement, during the period from the date of this Agreement and continuing until the earlier of the termination of this Agreement, unless C-COR shall otherwise consent in writing (which consent shall not be unreasonably withheld), ARRIS shall conduct its business and shall cause the businesses of its Subsidiaries to be conducted only in, and ARRIS and its Subsidiaries shall not take any action except in, the ordinary course of business and in the manner consistent with past practice; and ARRIS shall use reasonable commercial efforts to preserve substantially intact the business organization of ARRIS and its Subsidiaries, to keep available the services of the present officers, employees and consultants of ARRIS and its Subsidiaries and to preserve the present relationships of ARRIS and its Subsidiaries with customers, suppliers and other persons with which ARRIS or any of its Subsidiaries has significant business relations or take any actions which would reasonably be expected to interfere with or delay the consummation of the Merger or otherwise breach this Agreement. By way of amplification and not limitation, except as contemplated by this Agreement, neither ARRIS nor any of its Subsidiaries shall, during the period from the date of this Agreement and continuing until the earlier of the termination of this Agreement or the Merger, directly or indirectly do, or propose to do, any of the following without the prior written consent of C-COR (which consent shall not be unreasonably withheld):

(a) amend or otherwise change the Articles of Incorporation, Bylaws or Subsidiary Documents of ARRIS or any of its Subsidiaries;

(b) (i) declare, set aside, make or pay any dividend or other distribution (whether in cash, stock or property or any combination thereof) in respect of any of its capital stock, except that a wholly owned Subsidiary of ARRIS may declare and pay a dividend or make advances to ARRIS or (ii) split, combine or reclassify any of its capital stock or issue or authorize or propose the issuance of any other securities in respect of, in lieu of or in substitution for shares of its capital stock; and

(c) take, or agree in writing or otherwise to take, any of the actions described in Sections 6.3(a) and (b) above, or any action which would make any of the representations or warranties of ARRIS contained in this Agreement untrue or incorrect or prevent ARRIS from performing or cause ARRIS not to perform its covenants hereunder.

SECTION 6.4 —Recommendation of the Board of Directors of ARRIS. The Board of Directors of ARRIS shall recommend the approval of the issuance of ARRIS Common Stock pursuant to this Agreement in the Joint Proxy Statement. Neither the Board of Directors of ARRIS nor any committee thereof shall withdraw or modify, or propose to or resolve to withdraw or modify, in a manner adverse to C-COR, the ARRIS Board Recommendation.
