On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, each Selling Stockholder, severally and not jointly, agrees to sell to the Underwriters the number of Additional Shares set forth opposite its name on Schedule III hereto, and the Underwriters shall have the right to purchase, severally and not jointly, up to an aggregate of 3,966,060 Additional Shares.

(c) Each Selling Stockholder agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement, each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) of the Securities Act, or the Prospectus (if used within the period set forth in paragraph (f) of Section 7 hereof and as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made but only with respect to the Selling Stockholder Information provided by such Selling Stockholder. The liability of each Selling Stockholder under the indemnity agreement contained in this paragraph shall be limited to an amount equal to the net proceeds received by such Selling Stockholder from the sale of Shares by it under this Agreement.

(d) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each Selling Stockholder, the directors and officers of the Company and each Selling Stockholder who sign the Registration Statement and each person, if any, who controls the Company or any Selling Stockholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the preliminary prospectus, the Time of Sale Prospectus, any other free writing prospectus that the Company has filed or is required to file pursuant to Rule 433(d) of the Securities Act or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made, but only with reference to information relating to such Underwriter furnished to the Company in writing by Deutsche Bank and Xxxxxx Brothers on behalf of such Underwriter expressly for use in the Registration Statement, the preliminary prospectus, the Time of Sale

Prospectus, any other free writing prospectus that the Company has filed or is required to file pursuant to Rule 433(d) of the Securities Act or the Prospectus or any amendment or supplement thereto.

(e) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a), 9(b), 9(c) or 9(d), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable 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, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (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. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Stockholders and all persons, if any, who control any Selling Stockholder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Underwriters authorized to appoint counsel under this Section set forth in Schedule IV hereto. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Stockholders and such control persons of the Selling Stockholders, such firm shall be designated in writing by the Time Warner Selling Stockholders. 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. No

indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(f) To the extent the indemnification provided for in Section 9(a), 9(b), 9(c) or 9(d) is unavailable to an indemnified party in respect of any losses, claims, damages or liabilities referred to under such paragraph, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) if the indemnifying party is the Company (other than as set forth in clause 9(f)(iii) below) or the Selling Stockholders, in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares, (ii) if the indemnifying person is an Underwriter, in such proportion as is appropriate to reflect the relative fault of such Underwriter on the one hand and the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (iii) if the indemnifying person is the Company and the indemnified party is any Selling Stockholder, in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and such Selling Stockholder on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, or (iv) if the allocation provided by clause 9(f)(i), 9(f)(ii) or 9(f)(iii) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(f)(i) above or the relative fault referred to in clause 9(f)(ii) and 9(f)(iii) but also the relative fault (in cases covered by clause 9(f)(i)) or such relative benefits (in cases covered by clause 9(f)(ii) and 9(f)(iii)) of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company or the Selling Stockholders on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Selling Stockholders and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate public offering price of the Shares. The relative fault of the Company or the Selling Stockholders on the one hand and the Underwriters on the other hand 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 or by the Underwriters and the parties’ relative intent, knowledge, access to information

and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. The liability of any Selling Stockholder under the contribution agreement contained in this paragraph shall be limited to an amount equal to the net proceeds received by such Selling Stockholder from the sale of Shares by it under this Agreement.

(g) The Company, the Selling Stockholders and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 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 that does not take account of the equitable considerations referred to in Section 9(f). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(f) shall be deemed to include, subject to the limitations set forth above, 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 Section 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(h) The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company and the Selling Stockholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, by or on behalf of any Selling Stockholder, the officers or directors of any Selling Stockholder or any person controlling any Selling Stockholder, or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

10. Termination. The Underwriters may terminate this Agreement by notice given by Deutsche Bank and Xxxxxx Brothers to the Company and the Selling Stockholders, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange or the Nasdaq Stock Market, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States

shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the judgment of Deutsche Bank and Xxxxxx Brothers, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the judgment of Deutsche Bank and Xxxxxx Brothers, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

11. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Firm Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Firm Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Firm Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as Deutsche Bank and Xxxxxx Brothers may specify, to purchase the Firm Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Firm Shares that any Underwriter has agreed to purchase on such date pursuant to this Agreement be increased pursuant to this Section 11 by an amount in excess of one-ninth of such number of Firm Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Shares to be purchased, and arrangements satisfactory to Deutsche Bank and Xxxxxx Brothers, the Company and the Selling Stockholders for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders. In any such case either Deutsche Bank and Xxxxxx Brothers or the Selling Stockholders shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on

such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any one of them, because of any failure or refusal on the part of the Company or the Selling Stockholders to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company or the Selling Stockholders shall be unable to perform their obligations under this Agreement, the Company or the Selling Stockholders as the case may be will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

12. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

13. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

14. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

15. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

16. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to Deutsche Bank and Xxxxxx Brothers at the addresses set forth in Schedule IV hereto; if to the Company shall be delivered, mailed or sent to the address set forth in Schedule IV hereto; and if to the Selling Stockholders shall be delivered, mailed or sent to the addresses set forth in Schedule IV hereto.

Dear Sirs and Mesdames:

The undersigned understands that Deutsche Bank Securities Inc., Xxxxxx Brothers Inc. and X.X. Xxxxxx Securities Inc. (the “Underwriters”) severally propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Time Warner Telecom Inc., a Delaware corporation (the “Company”), and certain selling stockholders of the Company (the “Selling Stockholders”) providing for the public offering by the Underwriters of some of the Selling Stockholders’ shares of Class A common stock, par value $.01 per share of the Company (the “Securities”) (such offering referred to as the “Offering”).

To induce the Underwriters that may participate in the Offering to continue their efforts in connection with the Offering, the undersigned hereby agrees that, without the prior written consent of Deutsche Bank Securities Inc. and Xxxxxx Brothers Inc. on behalf of the Underwriters, he or she will not, during the period commencing on the date hereof and ending 90 days after the date of the final prospectus supplement relating to the Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of common stock of the Company or any securities convertible into or exercisable or exchangeable for common stock, or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the common stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (i) sales of shares of Class A Common Stock through existing Rule 10b5-1 plans as in effect on September 14, 2006, (ii) the transfer by a bona fide gift of Class A Common Stock, provided that (a) the transferee shall enter into a written agreement accepting the restrictions set forth in the preceding sentence and (b) no filing of a registration statement with the Commission or other filing with the Commission, including under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be

A-1

required or shall be voluntarily made in respect of the transfer during the 90-day restricted period, and (iii) transactions relating to shares of Class A Common Stock or other securities of the Company acquired in open market transactions after the completion of the Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made during the 90-day restricted period in connection with subsequent sales of Class A Common Stock or other securities of the Company acquired in such open market transactions.

In addition, the undersigned agrees that, without the prior written consent of Deutsche Bank Securities Inc. and Xxxxxx Brothers Inc. on behalf of the Underwriters, he or she will not, during the period commencing on the date hereof and ending 90 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Class A Common Stock or any security convertible into or exercisable or exchangeable for Class A Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Class A Common Stock except in compliance with the foregoing restrictions.

The undersigned understands that the Company, the Selling Stockholders and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the Offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

The undersigned understands that whether or not the Offering actually occurs depends on a number of factors, including market conditions. The Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

Very truly yours,
