(v) No consent, approval or waiver is required under any instrument or agreement to which such Selling Stockholder is a party or by which such Selling Stockholder is bound or under which he, she or it is entitled to any right or benefit, in connection with the offering, sale or purchase by the Underwriters of any of the Shares which may be sold by such Selling Stockholder under this Agreement or the consummation by such Selling Stockholder of any of the other transactions contemplated hereby. (vi) There are no affiliations or associations between any member of the NASD and such Selling Stockholder or any affiliate of such Selling Stockholder, except as set forth in the Registration Statement. 2. PURCHASE, SALE AND DELIVERY OF THE FIRM SHARES. (a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Sellers agree to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $17.955 per share, the number of Firm Shares set forth opposite the name of each Underwriter in Schedule I hereof, subject to adjustments in accordance with Section 9 hereof. The number of Firm Shares to be purchased by each Underwriter from each Seller shall be as nearly as practicable in the same proportion to the total number of Firm Shares being sold by each Seller as the number of Firm Shares being purchased by each Underwriter bears to the total number of Firm Shares to be sold hereunder. The obligations of the Company and of each of the Selling Stockholders shall be several and not joint. (b) Certificates in negotiable form for the total number of the Shares to be sold hereunder by the Selling Stockholders have been placed in custody with the Company as custodian (the "Custodian") pursuant to the Custody Agreement (the "Custodian Agreement") executed by 13 EXECUTION COPY each Selling Stockholder for delivery of all Firm Shares and any Option Shares to be sold hereunder by the Selling Stockholders. Each of the Selling Stockholders specifically agrees that the Firm Shares and any Option Shares represented by the certificates held in custody for the Selling Stockholders under the Custodian Agreement are subject to the interests of the Underwriters hereunder, that the arrangements made by the Selling Stockholders for such custody are to that extent irrevocable, and that the obligations of the Selling Stockholders hereunder shall not be terminable by any act or deed of the Selling Stockholders (or by any other person, firm or corporation including the Company, the Custodian or the Underwriters) or by operation of law (including the death of an individual Selling Stockholder or the dissolution of a corporate Selling Stockholder) or by the occurrence of any other event or events, except as set forth in the Custodian Agreement. If any such event should occur prior to the delivery to the Underwriters of the Firm Shares or the Option Shares hereunder, certificates for the Firm Shares or the Options Shares, as the case may be, shall be delivered by the Custodian in accordance with the terms and conditions of this Agreement as if such event has not occurred. The Custodian is authorized to receive and acknowledge receipt of the proceeds of sale of the Shares held by it against delivery of such Shares. (c) Payment for the Firm Shares to be sold hereunder is to be made in Federal (same day) funds to an account designated by the Company for the shares to be sold by it and to an account designated by the Custodian for the shares to be sold by the Selling Stockholders, in each case against delivery of certificates therefor to the Representatives for the several accounts of the Underwriters. Such payment and delivery are to be made through the facilities of The Depository Trust Company at 10:00 a.m., New York time, on the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as you and the Company shall agree upon, such time and date being herein referred to as the "Closing Date." (As used herein, "business day" means a day on which the New York Stock Exchange is open for trading and on which banks in New York are open for business and not permitted by law or executive order to be closed.) (d) In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Selling Stockholders listed on Schedule III hereto hereby grant an option to the several Underwriters to purchase the Option Shares at the price per share as set forth in the first paragraph of this Section 2. The maximum number of Option Shares to be sold by the Selling Stockholders is set forth opposite their respective names on Schedule III hereto. The option granted hereby may be exercised in whole or in part by giving written notice (i) at any time before the Closing Date and (ii) at any time, from time to time thereafter within 30 days after the date of this Agreement, by you, as Representatives of the several Underwriters, to the Company, the Attorney-in-Fact, and the Custodian setting forth the number of Option Shares as to which the several Underwriters are exercising the option and the time and date at which such certificates are to be delivered. If the option granted hereby is exercised in part, the respective number of Option Shares to be sold by each of the Selling Stockholders listed in Schedule III hereto shall be allocated between them in the order of priority set forth on Schedule III hereto. The time and date at which certificates for Option Shares are to be delivered shall be determined by the Representatives but shall not be earlier than three nor later than 10 full business days after the 14 EXECUTION COPY exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the "Option Closing Date"). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The number of Option Shares to be purchased by each Underwriter shall be in the same proportion to the total number of Option Shares being purchased as the number of Firm Shares being purchased by such Underwriter bears to the total number of Firm Shares, adjusted by you in such manner as to avoid fractional shares. The option with respect to the Option Shares granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters. You, as Representatives of the several Underwriters, may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Company and the Attorney-in-Fact. To the extent, if any, that the option is exercised, payment for the Option Shares shall be made on the Option Closing Date in Federal (same day) funds drawn to the order of the Company for the Option Shares to be sold by it and to the order of "Color Kinetics Incorporated, as Custodian" for the Option Shares to be sold by the Selling Stockholders against delivery of certificates therefor through the facilities of The Depository Trust Company, New York, New York. (e) If on the Closing Date or Option Closing Date, as the case may be, any Selling Stockholder fails to sell the Firm Shares or Option Shares which such Selling Stockholder has agreed to sell on such date as set forth in Schedule II hereto, the Company agrees that it will sell or arrange for the sale of that number of shares of Common Stock to the Underwriters which represents Firm Shares or the Option Shares which such Selling Stockholder has failed to so sell, as set forth in Schedule II hereto, or such lesser number as may be requested by the Representatives. 3. OFFERING BY THE UNDERWRITERS. It is understood that the several Underwriters are to make a public offering of the Firm Shares as soon as the Representatives deem it advisable to do so. The Firm Shares are to be initially offered to the public at the initial public offering price set forth in the Prospectus. The Representatives may from time to time thereafter change the public offering price and other selling terms. It is further understood that you will act as the Representatives for the Underwriters in the offering and sale of the Shares in accordance with a Master Agreement Among Underwriters entered into by you and the several other Underwriters. 4. COVENANTS OF THE COMPANY AND THE SELLING STOCKHOLDERS.

The Company will use its best efforts to prevent the issuance of any such order and to obtain as soon as possible the lifting thereof, if issued. (v) The Company will cooperate with the Representatives in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representatives may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent.

The Company will deliver to the Representatives at or before the Closing Date, four signed copies of the Registration Statement and all amendments thereto including all exhibits filed therewith, and will deliver to the Representatives such number of copies of the Registration Statement (including such number of copies of the exhibits filed therewith that may reasonably be requested), including documents incorporated by reference therein, and of all amendments thereto, as the Representatives may reasonably request. (vii) The Company will comply with the Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus. If during the period in which a prospectus (or, in lieu thereof, the notice referred to under Rule 173(a) under the Act) is required by law to be delivered by an Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with any law, the Company promptly will either (i) prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus or (ii) prepare and file with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the Prospectus so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the law.

(xvi) The Company will maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Company, a registrar for the Common Stock.

In rendering such opinion Foley Hoag LLP may rely as to matters governed by the laws of states other than Massachusetts or Federal laws on local counsel in such jurisdictions and as to the matters set forth in subparagraphs (xiii) through (xvii) on the opinions of other counsel representing the respective Selling Stockholders, provided that in each case Foley Hoag LLP shall state that they believe that they and the Underwriters are justified in relying on such other counsel. 24 EXECUTION COPY In addition to the matters set forth above, such opinion shall also include a statement to the effect that nothing has come to the attention of such counsel which leads them to believe that (i) the Registration Statement, at the time it became effective under the Act (including the information deemed to be a part of the Registration Statement at the time it became effective pursuant to Rules 430A, 430B or 430C under the Act) and as of the Closing Date or the Option Closing Date, as the case may be, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the General Disclosure Package, as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading and (iii) the Prospectus, or any supplement thereto, on the date it was filed pursuant to the Rules and Regulations and as of the Closing Date or the Option Closing Date, as the case may be, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that such counsel need express no view as to financial statements and schedules and other financial data therein). With respect to such statement, Foley Hoag LLP may state that their belief is based upon the procedures set forth therein, but is without independent check and verification. (c) The Representatives shall have received on the Closing Date or the Option Closing Date, as the case may be, the opinion of Smith, Anderson, Blount, Dorsett, Mitchell & Jernigan LLP, counsel for Cree, Inc., dated the Closing Date or the Option Closing Date, as the case may be, addressed to the Underwriters (and stating that it may be relied upon by counsel to the Underwriters) to the effect that: (i) This Agreement has been duly authorized by, and executed and delivered on behalf of, Cree. (ii) Cree has full legal right, power and authority, and any approval required by law (except such as have been made or previously obtained under the Act, and other than as required by State securities and Blue Sky laws as to which such counsel need express no opinion), to sell, assign, transfer and deliver the portion of the Shares to be sold by Cree. (iii) The Custodian Agreement and the Power of Attorney executed and delivered by Cree are valid and binding and enforceable against Cree in accordance with their respective terms. (iv) Assuming that payment for and delivery of the Shares to be sold by Cree has been made as provided herein, and assuming that at the time of such sale the Underwriters do not have "notice of any adverse claim" (within the meaning of Article 8 of the Uniform Commercial Code) to such Shares, the Underwriters will have acquired good and marketable title to the Shares being sold by Cree on the Closing Date, and the Option Closing Date, as the case may be, free and clear of any adverse claim, as defined in Article 8 of the Uniform Commercial Code. 25 EXECUTION COPY (v) No consent, approval or waiver is required under any instrument or agreement known to counsel for Cree to which Cree is a party or by which Cree is bound or under which it is entitled to any right or benefit in connection with the offering, sale or purchase by the Underwriters of any of the Shares which may be sold by Cree under this Agreement or the consummation by Cree of any of the other transactions contemplated hereby. In rendering such opinion, counsel for Cree may (x) expressly assume, based upon the representations and warranties of the Company contained in the Agreement and/or the opinion of counsel for the Company provided for in this Agreement, that the Shares to be sold by Cree have been duly and validly issued by the Company to Cree and are fully paid and non-assessable; (y) expressly assume, based upon the representations and warranties of Cree contained in the Underwriting Agreement that Cree has, on the Closing Date, or the Option Closing Date, as the case may be, good and marketable title to the Shares to be sold and delivered on such date; and (z) expressly identify those instruments or agreements that are within the knowledge of counsel for Cree for purposes of the opinion set forth in Section 6(c)(v) as (A) all documents filed as exhibits to Cree's Annual Report on Form 10-K for the fiscal year ended June 25, 2006 and subsequent periodic reports filed with the Commission prior to the date of this Agreement and (B) all agreements relating to Cree's acquisition of any of the Shares from the Company. (d) The Representatives shall have received on the Closing Date or the Option Closing Date, as the case may be, the opinion of Wolf Greenfield & Sacks, P.C., counsel for the Company, dated the Closing Date or the Option Closing Date, as the case may be, addressed to the Underwriters (and stating that it may be relied upon by counsel to the Underwriters) to the effect that: (i) As to the statements under the captions "Our Business - Intellectual Property Strategy," "Risks Related to Our Business - If we are unable to obtain and maintain patent protection for our technology and otherwise protect our intellectual property, the value of our technology and products will be adversely affected," and "Our Business - Intellectual Property Strategy and Technology" nothing has come to the attention of such counsel which caused them to believe that these portions of the Prospectus Supplement as of the date of the opinion, contained any untrue statement of a material fact or omitted to state a 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. (ii) To the knowledge of such counsel, no material action, suit, claim or proceeding relating to patents, patent rights or licenses, trademarks or trademark rights, copyrights, collaborative research, licenses or royalty arrangements or agreements or trade secrets, know-how or proprietary techniques, including processes and substances, owned by or affecting the business or operations of the Company, are pending or threatened against the Company or any of its officers or directors, other than those specifically identified in the portion of the Prospectus Suupplement under the caption "Our Business - Legal Proceedings." 26 EXECUTION COPY (iii) The Company is listed in the records of the United States Patent and Trademark Office (USPTO) as the holder of record of the patents listed on a schedule to such opinion (the "Patents") and each of the applications listed on a schedule to such opinion (the "Applications"). To the knowledge of such counsel, the Company is the sole owner of the Patents and Applications, and there are no claims of third parties to any ownership interest with respect to any of the Patents or Applications, and no lien appears of record at the USPTO. To the knowledge of such counsel, the Applications are being pursued by the Company. Such counsel is not aware of any material defect in formalities in connection with the filing of the Applications on behalf of the Company. (iv) The Company is listed in the records of the appropriate foreign patent offices as the sole holder of record of the foreign patents listed on a schedule to such opinion (the "Foreign Patents") and each of the applications listed on a schedule to such opinion (the "Foreign Applications"). Such counsel has no reason to believe that the Company is not the sole owner of the Foreign Patents and Foreign Applications, and knows of no claims of third parties to any ownership interest or lien with respect to any of the Foreign Patents or Foreign Applications. To the knowledge of such counsel, the Foreign Applications are being pursued by the Company. Such counsel is not aware of any material defect in formalities in connection with the filing of the Foreign Applications on behalf of the Company. (v) Nothing has come to the attention of such counsel which has caused such counsel to believe that the Patents or Foreign Patents do not include valid claims or are not enforceable. Such counsel has no knowledge of any facts or any reason that would prevent valid and enforceable claims from being issued or granted in any allowed Application or Foreign Application, thereby affording the Company useful patent protection with respect thereto. (e) The Representatives shall have received on the Closing Date or the Option Closing Date, as the case may be, the opinion of Lowrie Lando & Anastasi, LLP, counsel for the Company, dated the Closing Date or the Option Closing Date, as the case may be, addressed to the Underwriters (and stating that it may be relied upon by counsel to the Underwriters) to the effect that: (i) As to the statements under the captions "Risks Related to Our Business - We may incur substantial costs or lose important rights as a result of litigation or other proceedings relating to patent and other intellectual property rights," and "Our Business - Legal Proceedings," nothing has come to the attention of such counsel which caused them to believe that the above-mentioned sections of the Registration Statement and the Prospectus and any amendment or supplement thereto made available and reviewed by such counsel, at the time the Registration Statement became effective and at all times subsequent thereto up to and on the Closing Date and on any Option Closing Date, contained any untrue statement of a material fact or omitted to state a 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. 27 EXECUTION COPY (ii) Such counsel knows of no material action, suit, claim or proceeding relating to patents, patent rights or licenses, trademarks or trademark rights, copyrights, collaborative research, licenses or royalty arrangements or agreements or trade secrets, know-how or proprietary techniques, including processes and substances, owned by or affecting the business or operations of the Company which are pending or threatened against the Company or any of its officers or directors, other than as appear in the above-mentioned sections of the Registration Statement and the Prospectus. (f) The Representatives shall have received from Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel for the Underwriters, an opinion dated the Closing Date or the Option Closing Date, as the case may be, substantially to the effect that (i) the Company is a corporation duly incorporated and validly existing under, and by virtue of the laws of the State of Delaware, (ii) the Firm Shares and the Optional Shares have been duly authorized and, when issued and delivered in accordance with the terms hereto, will be validly issued, fully paid and non-assessable and (iii) the Company is a duly incorporated and validly existing corporation under the laws of the State of Delaware. In rendering such opinion Wilson Sonsini Goodrich & Rosati, Professional Corporation may rely as to all matters governed other than by the laws of the State of Delaware or Federal laws on the opinion of counsel referred to in Paragraph (b) of this Section 6. In addition to the matters set forth above, such opinion shall also include a statement to the effect that nothing has come to the attention of such counsel which leads them to believe that (i) the Registration Statement, or any amendment thereto, as of the time it became effective under the Act (including the information deemed to be a part of the Registration Statement at the time it became effective pursuant to Rules 430A, 430B or 430C under the Act) contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the General Disclosure Package, as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading and (iii) the Prospectus, or any supplement thereto, on the date it was filed pursuant to the Rules and Regulations and as of the date hereof, contained or contains an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that such counsel need express no view as to financial statements and schedules and other financial data therein). With respect to such statement, Wilson Sonsini Goodrich & Rosati, Professional Corporation may state that their belief is based upon the procedures set forth therein, but is without independent check and verification.

(k) The Company and the Selling Stockholders shall have furnished to the Representatives such further certificates and documents confirming the representations and warranties, covenants and conditions contained herein and related matters as the Representatives may reasonably have requested. (l) The Firm Shares and Option Shares, if any, have been duly listed, subject to notice of issuance, on the Nasdaq Global Market.

The opinions and certificates mentioned in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in all material respects satisfactory to the Representatives and to Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel for the Underwriters. If any of the conditions hereinabove provided for in this Section 6 shall not have been fulfilled when and as required by this Agreement to be fulfilled, the obligations of the 30 EXECUTION COPY Underwriters hereunder may be terminated by the Representatives by notifying the Company and the Selling Stockholders of such termination in writing or by telegram at or prior to the Closing Date or the Option Closing Date, as the case may be. In such event, the Selling Stockholders, the Company and the Underwriters shall not be under any obligation to each other (except to the extent provided in Sections 5 and 8 hereof). 7. CONDITIONS OF THE OBLIGATIONS OF THE SELLERS. The obligations of the Sellers to sell and deliver the portion of the Shares required to be delivered as and when specified in this Agreement are subject to the conditions that at the Closing Date or the Option Closing Date, as the case may be, no stop order suspending the effectiveness of the Registration Statement shall have been issued and in effect or proceedings therefor initiated or threatened. 8. INDEMNIFICATION. (a) The Company agrees: (1) to indemnify and hold harmless each Underwriter, the directors, officers, agents, representatives and attorneys of each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter, the directors, officers, agents, representatives and attorneys of each Underwriter or any such controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, (ii) with respect to the Registration Statement or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) with respect to any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iv) with respect to any Issuer Free Writing Prospectus, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, when considered together with the General Disclosure Package and in the light of the circumstances under which they were made, not misleading; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use therein, 31 EXECUTION COPY it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 13 herein; and (2) to reimburse each Underwriter, each Underwriters' directors, officers, agents, representatives and attorneys, and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Underwriter, each Underwriters' directors, officers, agents, representatives and attorneys or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters were not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto. (b) Each Selling Stockholder, severally and not jointly, agrees to indemnify the Underwriters, each Underwriters' directors, officers, agents, representatives and attorneys and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter or controlling person may become subject under the Act or otherwise insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, or (ii) with respect to the Registration Statement or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) with respect to any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iv) with respect to any Issuer Free Writing Prospectus, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, when considered together with the General Disclosure Package and in the light of the circumstances under which they were made, not misleading; provided, however, that the Selling Stockholders will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company or the Selling Stockholders by or through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 13 herein; provided further, that Cree will be liable in each case only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, or such amendment or supplement, in reliance upon and in conformity with written 32 EXECUTION COPY information furnished to the Company by or through Cree specifically for use therein. The liability of a Selling Stockholder under the indemnity agreement contained in this paragraph shall be limited to an amount not exceeding the net proceeds received by such Selling Stockholder from the sale of Shares hereunder (after deducting the underwriting discount). This indemnity obligation will be in addition to any liability which the Company or the Selling Stockholders may otherwise have. (c) Each Underwriter severally and not jointly will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the Registration Statement, the Selling Stockholders, and each person, if any, who controls the Company or the Selling Stockholders within the meaning of the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer, Selling Stockholder or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, (ii) with respect to the Registration Statement or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) with respect to any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iv) with respect to any Issuer Free Writing Prospectus, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, when considered together with the General Disclosure Package and in the light of the circumstances under which they were made, not misleading, and will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, Selling Stockholder or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 13 herein. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have. (d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 8, such person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing. No indemnification provided for in Section 8(a), (b) or (c) shall be available to any party who shall fail to give notice as provided in this Section 8(d) if the party to whom notice was not given was unaware of the proceeding to which such 33 EXECUTION COPY notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a), (b) or (c). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel reasonably acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by you in the case of parties indemnified pursuant to Section 8(a) or (b) and by the Company and the Selling Stockholders in the case of parties indemnified pursuant to Section 8(c). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding. (e) To the extent the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the 34 EXECUTION COPY Company and the Selling Stockholders on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholders on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholders bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Stockholders on the one hand or the Underwriters on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 8(e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter, (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation, and (iii) no Selling Stockholder shall be required to contribute any amount in excess of the proceeds received by such Selling Stockholder from the Underwriters in the offering. The Underwriters' obligations in this Section 8(e) to contribute are several in proportion to their respective underwriting obligations and not joint. (f) In any proceeding relating to the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any supplement or amendment thereto, each party against whom contribution may be sought under this Section 8 hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be served upon it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join it as an additional defendant in any such proceeding in which such other contributing party is a party. 35 EXECUTION COPY (g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter, its directors or officers or any person controlling any Underwriter, the Company, its directors or officers or any persons controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, its directors or officers or any person controlling any Underwriter, or to the Company, its directors or officers, or any person controlling the Company, or to a Selling Stockholder or any person controlling a Selling Stockholder, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8. 36 EXECUTION COPY 9. DEFAULT BY UNDERWRITERS. If on the Closing Date or the Option Closing Date, as the case may be, any Underwriter shall fail to purchase and pay for the portion of the Shares which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company or a Selling Stockholder), you, as Representatives of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company and the Selling Stockholders such amounts as may be agreed upon and upon the terms set forth herein, the Shares which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours you, as such Representatives, shall not have procured such other Underwriters, or any others, to purchase the Shares agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of shares with respect to which such default shall occur does not exceed 10% of the Shares to be purchased on the Closing Date or the Option Closing Date, as the case may be, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Shares which they are obligated to purchase hereunder, to purchase the Shares which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of shares of Shares with respect to which such default shall occur exceeds 10% of the Shares to be purchased on the Closing Date or the Option Closing Date, as the case may be, the Company and the Selling Stockholders or you as the Representatives of the Underwriters will have the right, by written notice given within the next 36-hour period to the parties to this Agreement, to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company or of the Selling Stockholders except to the extent provided in Sections 5 and 8 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section 9, the Closing Date or Option Closing Date, as the case may be, may be postponed for such period, not exceeding seven days, as you, as Representatives, may determine in order that the required changes in the Registration Statement, the General Disclosure Package or in the Prospectus or in any other documents or arrangements may be effected. The term "Underwriter" includes any person substituted for a defaulting Underwriter. Any action taken under this Section 9 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. 10. NOTICES.

As Representative of the Several Underwriters c/o Deutsche Bank Securities Inc. 60 Wall Street, 4th Floor New York, New York 10005 Ladies and Gentlemen: The undersigned understands that Deutsche Bank Securities Inc., as representative (the "Representative") of the several underwriters (the "Underwriters"), proposes to enter into an Underwriting Agreement (the "Underwriting Agreement") with Color Kinetics Incorporated (the "Company"), providing for the public offering by the Underwriters, including the Representative, of common stock, par value $0.001 per share (the "Common Stock"), of the Company and certain selling shareholders (the "Public Offering"). To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned agrees that, without the prior written consent of the Representative, the undersigned will not, directly or indirectly, offer, sell, pledge, contract to sell (including any short sale), grant any option to purchase or otherwise dispose of any shares of Common Stock (including, without limitation, shares of Common Stock of the Company which may be deemed to be beneficially owned by the undersigned on the date hereof in accordance with the rules and regulations of the Securities and Exchange Commission, shares of Common Stock which may be issued upon exercise of a stock option or warrant and any other security convertible into or exchangeable for Common Stock) or enter into any Hedging Transaction (as defined below) relating to the Common Stock (each of the foregoing referred to as a "Disposition") during the period specified in the following paragraph (the "Lock-Up Period"). The foregoing restriction is expressly intended to preclude the undersigned from engaging in any Hedging Transaction or other transaction which is designed to or reasonably expected to lead to or result in a Disposition during the Lock-Up Period even if the securities would be disposed of by someone other than the 46 EXECUTION COPY undersigned. "Hedging Transaction" means any short sale (whether or not against the box) or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from the Common Stock. The initial Lock-Up Period will commence on the date hereof and continue until, and include, the date that is 90 days after the date of the final prospectus relating to the Public Offering (the "Initial Lock-Up Period"); provided, however, that if (1) during the last 17 days of the Initial Lock-Up Period, (A) the Company releases earnings results, or (B) the Company discloses, through a press release or the filing of a Current Report on Form 8-K, the occurrence of a material event relating to the Company, or (2) prior to the expiration of the Initial Lock-Up Period, the Company announces that it will release earnings results during the 16-day period following the last day of the Initial Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of the release of the earnings results or the announcement of material news or the occurrence of a material event relating to the Company, as the case may be, unless the Representative waives, in writing, such extension. Notwithstanding the foregoing, the undersigned may transfer (a) shares of Common Stock acquired in open market transactions by the undersigned after pricing of the Public Offering, (b) shares of Common Stock in connection with the net exercise of stock options or warrants held by the undersigned (provided that any such shares issued upon net exercise of stock options or warrants shall continue to be subject to the applicable provisions of this agreement), and (c) any or all of the undersigned's shares of Common Stock or other Company securities if the transfer is (i) by gift, will or intestacy, (ii) to his or her family for estate planning purposes (including family trusts, family corporations, family limited liability companies or family partnerships, the direct or indirect beneficiaries of which are the undersigned and his or her immediate family) or (iii) by distribution to partners, members or shareholders of the undersigned; provided, however, that in the case of a transfer pursuant to clause (c) above, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding the securities subject to the provisions of this Lock-Up Agreement. The undersigned agrees that the Company may, and that the undersigned will, (i) with respect to any shares of Common Stock or other Company securities for which the undersigned is the record holder, cause the transfer agent for the Company to note stop transfer instructions with respect to such securities on the transfer books and records of the Company and (ii) with respect to any shares of Common Stock or other Company securities for which the undersigned is the beneficial holder but not the record holder, cause the record holder of such securities to cause the transfer agent for the Company to note stop transfer instructions with respect to such securities on the transfer books and records of the Company. In addition, the undersigned hereby waives any and all notice requirements and rights with respect to registration of securities pursuant to any agreement, understanding or otherwise setting forth the terms of any security of the Company held by the undersigned, including any registration 47 EXECUTION COPY rights agreement to which the undersigned and the Company may be party; provided that such waiver shall apply only to the proposed Public Offering, and any other action taken by the Company in connection with the proposed Public Offering. The undersigned hereby agrees that, to the extent that the terms of this Lock-Up Agreement conflict with or are in any way inconsistent with any registration rights agreement to which the undersigned and the Company may be a party, this Lock-Up Agreement supersedes such registration rights agreement. The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned and any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned. Notwithstanding anything herein to the contrary, if the Company notifies the Representative in writing that it does not intend to proceed with the Public Offering, if the Underwriting Agreement does not become effective by 11:59 p.m., Boston, Massachusetts time, on March 31, 2007, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to the payment for and delivery of the Shares, then this agreement shall be of no further force or effect.
