therein and any supplements and amendments thereto or to the Registration

(b) Before amending or supplementing the Registration Statement, the Time of
Sale Prospectus or the Prospectus, to furnish to each Underwriter a copy of each
such proposed amendment or supplement and not to file any such proposed
amendment or supplement to which the Underwriters reasonably object.

prospectus to be prepared by or on behalf of, used by, or referred to by the
Company and not to use or refer to any proposed free writing prospectus to which

it is necessary to amend or supplement the Time of Sale Prospectus to comply
with applicable law, forthwith to prepare, file with the Commission and furnish,

amendments or supplements to the Time of Sale Prospectus so that the statements
in the Time of Sale Prospectus as so amended or supplemented will not, in the
light of the circumstances when delivered to a prospective purchaser, be
misleading or so that the Time of Sale Prospectus, as amended or supplemented,
will no longer conflict with the Registration Statement, or so that the Time of
Sale Prospectus, as amended or supplemented, will comply with applicable law.

 

23

Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the
Securities Act) is required by law to be delivered in connection with sales by
an Underwriter or dealer, any event shall occur or condition exist as a result
of which it is necessary to amend or supplement the Prospectus in order to make
the statements therein, in the light of the circumstances when the Prospectus
(or in lieu thereof the notice referred to in Rule 173(a) under the Securities
Act) is delivered to a purchaser, not misleading, or if, in the reasonable
opinion of counsel for the Underwriters, it is necessary to amend or supplement
the Prospectus to comply with applicable law, forthwith to prepare, file with
the Commission and furnish, at its own expense, to the Underwriters and to the
dealers (whose names and addresses Deutsche Bank and Lehman Brothers will
furnish to the Company) to which Shares may have been sold by Deutsche Bank,
Lehman Brothers and J.P. Morgan Securities Inc. on behalf of the Underwriters
and to any other dealers upon request, either amendments or supplements to the
Prospectus so that the statements in the Prospectus as so amended or
supplemented will not, in the light of the circumstances when the Prospectus (or
in lieu thereof the notice referred to in Rule 173(a) under the Securities Act)
is delivered to a purchaser, be misleading or so that the Prospectus, as amended
or supplemented, will comply with applicable law.

8. Covenants of the Underwriters. Each Underwriter severally covenants with the
Company not to take any action that would result in the Company being required
to file with the Commission under Rule 433(d) a free writing prospectus prepared
by or on behalf of such Underwriter that otherwise would not be required to be
filed by the Company thereunder, but for the action of the Underwriter. The
Underwriters further covenant with the Company to pay or cause to be paid the
costs and expenses of the Company relating to investor presentations on any
“road show” undertaken in connection with the marketing of the offering of the
Shares.

9. Indemnity and Contribution. (a) The Company agrees to indemnify and hold

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, any electronic roadshow or the Prospectus
or any amendment or supplement 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, except insofar as such losses, claims,
damages or liabilities are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information relating to any
Underwriter furnished to the Company in writing by such Underwriter through
Deutsche Bank and Lehman Brothers expressly for use therein.

(b) The Company agrees to indemnify and hold harmless each Selling Stockholder,
each person, if any, who controls any Selling Stockholder within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act, and
each affiliate of any Selling Stockholder 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, any electronic road show 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

 

26

--------------------------------------------------------------------------------

circumstances in which they were made, except for losses, claims, damages or
liabilities with respect to Selling Stockholder Information provided by such
Selling Stockholder.

(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 Lehman Brothers on behalf of such Underwriter
expressly for use in the Registration Statement, the preliminary prospectus, the
Time of Sale

 

27

--------------------------------------------------------------------------------

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

 

28

--------------------------------------------------------------------------------

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

 

29

--------------------------------------------------------------------------------

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 Lehman 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

 

30

--------------------------------------------------------------------------------

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 Lehman 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 Lehman 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 Lehman 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 Lehman 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 Lehman 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

 

31

--------------------------------------------------------------------------------

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 Lehman 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

Dear Sirs and Mesdames:

The undersigned understands that Deutsche Bank Securities Inc., Lehman Brothers
Inc. and J.P. Morgan 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
Lehman 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 Lehman 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,

    (Name)
