Exhibit 10.1

COVAD COMMUNICATIONS GROUP, INC.

INDEMNIFICATION AGREEMENT

     This Indemnification Agreement (“Agreement”) is made as of this 11th day of April, 2007, by
and between Covad Communications Group, Inc., a Delaware corporation (the “Company”), and Justin
Spencer (“Indemnitee”).

     WHEREAS, the Company and Indemnitee recognize the increasing difficulty in obtaining
directors’ and officers’ liability insurance, the significant increases in the cost of such
insurance and the general reductions in the coverage of such insurance;

     WHEREAS, the Company and Indemnitee further recognize the substantial increase in corporate
litigation in general, subjecting officers and directors to expensive litigation risks at the same
time as the availability and coverage of liability insurance has been severely limited; and

     WHEREAS, the Company desires to attract and retain the services of highly qualified
individuals, such as Indemnitee, to serve as officers and directors of the Company and to indemnify
its officers and directors so as to provide them with the maximum protection permitted by law.

     NOW, THEREFORE, in consideration for Indemnitee’s services as an officer or director of the
Company, the Company and Indemnitee hereby agree as follows:

     1. Indemnification.

          (a) Third Party Proceedings. The Company shall indemnify Indemnitee if Indemnitee is or was a
party or is threatened to be made a party to any threatened, pending or completed action, suit,
proceeding or any alternative dispute resolution mechanism, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the Company) by reason of the fact
that Indemnitee is or was a director, officer, employee or agent of the Company, or any subsidiary
of the Company, or by reason of the fact that Indemnitee is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines
and amounts paid in settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) actually and reasonably incurred by Indemnitee in
connection with such action, suit or proceeding if Indemnitee acted in good faith and in a manner
Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and,
with respect to any criminal action or proceeding, had no reasonable cause to believe Indemnitee’s
conduct was unlawful. The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself,
create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee
reasonably believed to be in or not opposed to the best interests of the Company, and, with respect
to any criminal action or proceeding, had reasonable cause to believe that Indemnitee’s conduct was
unlawful.

 

 

          (b) Proceedings By or in the Right of the Company. The Company shall indemnify Indemnitee if
Indemnitee was or is a party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the Company or any subsidiary of the Company to
procure a judgment in its favor by reason of the fact that Indemnitee is or was a director,
officer, employee or agent of the Company, or any subsidiary of the Company, or by reason of the
fact that Indemnitee is or was serving at the request of the Company as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys’ fees) and, to the fullest extent permitted by law, amounts
paid in settlement actually and reasonably incurred by Indemnitee in connection with the defense or
settlement of such action or suit if Indemnitee acted in good faith and in a manner Indemnitee
reasonably believed to be in or not opposed to the best interests of the Company, except that no
indemnification shall be made in respect of any claim, issue or matter as to which Indemnitee shall
have been adjudged to be liable to the Company unless and only to the extent that the Court of
Chancery of the State of Delaware or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in view of all the
circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery of the State of Delaware or such other court shall deem
proper.

          (c) Mandatory Payment of Expenses. To the extent that Indemnitee has been successful on the
merits or otherwise in defense of any action, suit or proceeding referred to in Subsections (a) and
(b) of this Section 1, or in defense of any claim, issue or matter therein, Indemnitee shall be
indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by
Indemnitee in connection therewith.

     2. Agreement to Serve. In consideration of the protection afforded by this Agreement, if
Indemnitee is a director of the Company he agrees to serve at least for the 90 days after the
effective date of this Agreement as a director and not to resign voluntarily during such period
without the written consent of a majority of the Board of Directors. If Indemnitee is an officer of
the Company not serving under an employment contract, he agrees to serve in such capacity at least
for 90 days and not to resign voluntarily during such period without the written consent of a
majority of the Board of Directors. Following the applicable period set forth above, Indemnitee
agrees to continue to serve in such capacity at the will of the Company (or under separate
agreement, if such agreement exists) so long as he is duly appointed or elected and qualified in
accordance with the applicable provisions of the Bylaws of the Company or any subsidiary of the
Company or until such time as he tenders his resignation in writing. Nothing contained in this
Agreement is intended to create in Indemnitee any right to continued employment.

     3. Expenses; Indemnification Procedure.

          (a) Advancement of Expenses. The Company shall advance all expenses incurred by Indemnitee in
connection with the investigation, defense, settlement or appeal of any civil or criminal action,
suit or proceeding referenced in Section 1(a) or (b) hereof (but not amounts actually paid in
settlement of any such action, suit or proceeding). Indemnitee hereby undertakes to repay such
amounts advanced only if, and to the extent that, it shall ultimately be determined that

-2-

 

Indemnitee
is not entitled to be indemnified by the Company as authorized hereby. The advances to
be made hereunder shall be paid by the Company to Indemnitee within thirty (30) days following
delivery of a written request therefor by Indemnitee to the Company.

          (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a condition precedent to his right
to be indemnified under this Agreement, give the Company notice in writing as soon as practicable
of any claim made against Indemnitee for which indemnification will or could be sought under this
Agreement. Notice to the Company shall be directed to the President of the Company at the address
shown on the signature page of this Agreement (or such other address as the Company shall designate
in writing to Indemnitee and given as provided in Section 14). In addition, Indemnitee shall give
the Company such information and cooperation as it may reasonably require and as shall be within
Indemnitee’s power.

          (c) Procedure. Any indemnification and advances provided for in Section 1 and this Section 3
shall be made no later than thirty (30) days after receipt of the written request of Indemnitee.
If a claim under this Agreement, under any statute, or under any provision of the Company’s
Certificate of Incorporation or Bylaws providing for indemnification, is not paid in full by the
Company within thirty (30) days after a written request for payment thereof has first been received
by the Company, Indemnitee may, but need not, at any time thereafter bring an action against the
Company to recover the unpaid amount of the claim and, subject to Section 14 of this Agreement,
Indemnitee shall also be entitled to be paid for the expenses (including attorneys’ fees) of
bringing such action. It shall be a defense to any such action (other than an action brought to
enforce a claim for expenses incurred in connection with any action, suit or proceeding in advance
of its final disposition) that Indemnitee has not met the standards of conduct which make it
permissible under applicable law for the Company to indemnify Indemnitee for the amount claimed.
However, Indemnitee shall be entitled to receive interim payments of expenses pursuant to
Subsection 3(a) unless and until such defense may be finally adjudicated by court order or judgment
from which no further right of appeal exists. It is the parties’ intention that if the Company
contests Indemnitee’s right to indemnification, the question of Indemnitee’s right to
indemnification shall be for the court to decide, and neither the failure of the Company (including
its Board of Directors, any committee or subgroup of the Board of Directors, independent legal
counsel, or its stockholders) to have made a determination that indemnification of Indemnitee is
proper in the circumstances because Indemnitee has met the applicable standard of conduct required
by applicable law, nor an actual determination by the Company (including it Board of Directors, any
committee or subgroup of the Board of Directors, independent legal counsel, or its stockholders)
that Indemnitee has not met such applicable standard of conduct, shall create a presumption that
Indemnitee has or has not met the applicable standard of conduct.

          (d) Notice to Insurers. If, at the time of the receipt of a notice of a claim pursuant to
Section 3(b) hereof, the Company has director and officer liability insurance in effect, the
Company shall give prompt notice of the commencement of such proceeding to the insurers in
accordance with the procedures set forth in the respective policies. The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee,
all amounts payable as a result of such proceeding in accordance with the terms of such policies.

-3-

 

          (e) Selection of Counsel. In the event the Company shall be obligated under Section 3(a)
hereof to pay the expenses of any proceeding against Indemnitee, the Company, if appropriate, shall
be entitled to assume the defense of such proceeding, with counsel subject to the approval of
Indemnitee, which shall not be unreasonably withheld. After delivery of written notice of the
assumption of the defense, approval of such counsel by Indemnitee as described above and the
retention of such counsel by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees of counsel subsequently incurred by Indemnitee with respect to the same
proceeding, provided that (i) Indemnitee shall have the right to employ his counsel in any such
proceeding at Indemnitee’s expense; and (ii) if (A) the employment of counsel by Indemnitee has
been previously authorized by the Company, (B) Indemnitee shall have reasonably concluded that
there may be a conflict of interest between the Company and Indemnitee in the conduct of any such
defense, or (C) the Company shall not, in fact, have employed counsel to assume the defense of such
proceeding, then the fees and expenses of Indemnitee’s counsel shall be at the expense of the
Company.

     4. Additional Indemnification Rights; Nonexclusivity.

          (a) Scope. Notwithstanding any other provision of this Agreement, the Company hereby agrees
to indemnify the Indemnitee to the fullest extent permitted by law, notwithstanding that such
indemnification is not specifically authorized by the other provisions of this Agreement, the
Company’s Certificate of Incorporation, the Company’s Bylaws or by statute. In the event of any
change, after the date of this Agreement, in any applicable law, statute, or rule which expands the
right of a Delaware corporation to indemnify a member of its board of directors or an officer, such
changes shall be, ipso facto, within the purview of Indemnitee’s rights and Company’s obligations,
under this Agreement. In the event of any change in any applicable law, statute or rule which
narrows the right of a Delaware corporation to indemnify a member of its board of directors or an
officer, such changes, to the extent not otherwise required by such law, statute or rule to be
applied to this Agreement shall have no effect on this Agreement or the parties’ rights and
obligations hereunder.

          (b) Nonexclusivity. The indemnification provided by this Agreement shall not be deemed
exclusive of any rights to which Indemnitee may be entitled under the Company’s Certificate of
Incorporation, its Bylaws, any agreement, any vote of stockholders or disinterested Directors, the
General Corporation Law of the State of Delaware, or otherwise, both as to action in Indemnitee’s
official capacity and as to action in another capacity while holding such office. The
indemnification provided under this Agreement shall continue as to Indemnitee for any action taken
or not taken while serving in an indemnified capacity even though he may have ceased to serve in
such capacity at the time of any action, suit or other covered proceeding.

     5. Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement
to indemnification by the Company for some or a portion of the expenses, judgments, fines or
penalties actually or reasonably incurred by him in the investigation, defense, appeal or
settlement of any civil or criminal action, suit or proceeding, but not, however, for the total
amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion of such
expenses, judgments, fines or penalties to which Indemnitee is entitled.

-4-

 

     6. Mutual Acknowledgement. Both the Company and Indemnitee acknowledge that in certain
instances, Federal law or applicable public policy may prohibit the Company from indemnifying its
directors and officers under this Agreement or otherwise. Indemnitee understands and acknowledges
that the Company has undertaken or may be required in the future to undertake with the Securities
and Exchange Commission to submit the question of indemnification to a court in certain
circumstances for a determination of the Company’s right under public policy to indemnify
Indemnitee.

     7. Officer and Director Liability Insurance. The Company shall, from time to time, make the
good faith determination whether or not it is practicable for the Company to obtain and maintain a
policy or policies of insurance with reputable insurance companies providing the officers and
directors of the Company with coverage for losses from wrongful acts, or to ensure the Company’s
performance of its indemnification obligations under this Agreement. Among other considerations,
the Company will weigh the costs of obtaining such insurance coverage against the protection
afforded by such coverage. In all policies of director and officer liability insurance, Indemnitee
shall be named as an insured in such a manner as to provide Indemnitee the same rights and benefits
as are accorded to the most favorably insured of the Company’s directors, if Indemnitee is a
director; or of the Company’s officers, if Indemnitee is not a director of the Company but is an
officer. Notwithstanding the foregoing, the Company shall have no obligation to obtain or maintain
such insurance if the Company determines in good faith that such insurance is not reasonably
available, if the premium costs for such insurance are disproportionate to the amount of coverage
provided, if the coverage provided by such insurance is limited by exclusions so as to provide an
insufficient benefit, or if Indemnitee is covered by similar insurance maintained by a subsidiary
or parent of the Company.

     8. Severability. Nothing in this Agreement is intended to require or shall be construed as
requiring the Company to do or fail to do any act in violation of applicable law. The Company’s
inability, pursuant to court order, to perform its obligations under this Agreement shall not
constitute a breach of this Agreement. The provisions of this Agreement shall be severable as
provided in this Section 8. If this Agreement or any portion hereof shall be invalidated on any
ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify
Indemnitee to the full extent permitted by any applicable portion of this Agreement that shall not
have been invalidated, and the balance of this Agreement not so invalidated shall be enforceable in
accordance with its terms.

     9. Exceptions. Any other provision herein to the contrary notwithstanding, the Company shall
not be obligated pursuant to the terms of this Agreement:

          (a) Claims Initiated by Indemnitee. To indemnify or advance expenses to Indemnitee with
respect to proceedings or claims initiated or brought voluntarily by Indemnitee and not by way of
defense, except with respect to proceedings brought to establish or enforce a right to
indemnification under this Agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law, but such indemnification or advancement of
expenses may be provided by the Company in specific cases if the Board of Directors has approved
the initiation or bringing of such suit; or

-5-

 

          (b) Lack of Good Faith. To indemnify Indemnitee for any expenses incurred by the Indemnitee
with respect to any proceeding instituted by Indemnitee to enforce or interpret this Agreement, if
a court of competent jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous; or

          (c) Insured Claims. To indemnify Indemnitee for expenses or liabilities of any type
whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes or penalties, and
amounts paid in settlement) which have been paid directly to Indemnitee by an insurance carrier
under a policy of officers’ and directors’ liability insurance maintained by the Company.

          (d) Claims Under Section 16(b). To indemnify Indemnitee for expenses and the payment of
profits arising from the purchase and sale by Indemnitee of securities in violation of Section
16(b) of the Securities Exchange Act of 1934, as amended, or any similar successor statute.

     10. Construction of Certain Phrases.

          (a) For purposes of this Agreement, references to the “Company” shall include, in addition to
the resulting corporation, any constituent corporation (including any constituent of a constituent)
absorbed in a consolidation or merger which, if its separate existence had continued, would have
had power and authority to indemnify its directors, officers, and employees or agents, so that if
Indemnitee is or was a director, officer, employee or agent of such constituent corporation, or is
or was serving at the request of such constituent corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other enterprise, Indemnitee
shall stand in the same position under the provisions of this Agreement with respect to the
resulting or surviving corporation as Indemnitee would have with respect to such constituent
corporation if its separate existence had continued.

          (b) For purposes of this Agreement, references to “other enterprises” shall include employee
benefit plans; references to “fines” shall include any excise taxes assessed on Indemnitee with
respect to an employee benefit plan; and references to “serving at the request of the Company”
shall include any service as a director, officer, employee or agent of the Company which imposes
duties on, or involves services by, such director, officer, employee or agent with respect to an
employee benefit plan, its participants, or beneficiaries; and if Indemnitee acted in good faith
and in a manner Indemnitee reasonably believed to be in the interest of the participants and
beneficiaries of an employee benefit plan, Indemnitee shall be deemed to have acted in a manner
“not opposed to the best interests of the Company” as referred to in this Agreement.

     11. Counterparts. This Agreement may be executed in one or more counterparts, each of which
shall constitute an original.

     12. Successors and Assigns. This Agreement shall be binding upon the Company and its
successors and assigns, and shall inure to the benefit of Indemnitee and Indemnitee’s estate,
heirs, legal representatives and assigns.

     13. Attorneys’ Fees. In the event that any action is instituted by Indemnitee under this
Agreement to enforce or interpret any of the terms hereof, Indemnitee shall be entitled to be paid
all

-6-

 

court costs and expenses, including reasonable attorneys’ fees, incurred by Indemnitee with
respect to such action, unless as a part of such action, the court of competent jurisdiction
determines that each of the material assertions made by Indemnitee as a basis for such action were
not made in good faith or were frivolous. In the event of an action instituted by or in the name
of the Company under this Agreement or to enforce or interpret any of the terms of this Agreement,
Indemnitee shall be entitled to be paid all court costs and expenses, including attorneys’ fees,
incurred by Indemnitee in defense of such action (including with respect to Indemnitee’s
counterclaims and cross-claims made in such action), unless as a part of such action the court
determines that each of Indemnitee’s material defenses to such action were made in bad faith or
were frivolous.

     14. Notice. All notices, requests, demands and other communications under this Agreement
shall be in writing and shall be deemed duly given (i) if delivered by hand and receipted for by
the party addressee, on the date of such receipt, or (ii) if mailed by domestic certified or
registered mail with postage prepaid, on the third business day after the date postmarked.
Addresses for notice to either party are as shown on the signature page of this Agreement, or as
subsequently modified by written notice.

     15. Consent to Jurisdiction. The Company and Indemnitee each hereby irrevocably consent to
the jurisdiction of the courts of the State of Delaware for all purposes in connection with any
action or proceeding which arises out of or relates to this Agreement and agree that any action
instituted under this Agreement shall be brought only in the state courts of the State of Delaware.

     16. Choice of Law. This Agreement shall be governed by and its provisions construed in
accordance with the laws of the State of Delaware, as applied to contracts between Delaware
residents entered into and to be performed entirely within Delaware without regard to the conflict
of law principles thereof.

     17. Period of Limitations. No legal action shall be brought and no cause of action shall be
asserted by or in the right of the Company against Indemnitee, Indemnitee’s estate, spouse, heirs,
executors or personal or legal representatives after the expiration of two years from the date of
accrual of such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal action within such
two-year period; provided, however, that if any shorter period of limitations is
otherwise applicable to any such cause of action, such shorter period shall govern.

     18. Subrogation. In the event of payment under this Agreement, the Company shall be
subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall
execute all documents required and shall do all acts that may be necessary to secure such rights
and to enable the Company effectively to bring suit to enforce such rights.

     19. Amendment and Termination. No amendment, modification, termination or cancellation of
this Agreement shall be effective unless it is in writing signed by both the parties hereto. No
waiver of any of the provisions of this Agreement shall be deemed or shall constitute a
waiver of any other provisions hereof (whether or not similar) nor shall such waiver
constitute a continuing waiver.

-7-

 

     20. Integration and Entire Agreement. This Agreement sets forth the entire understanding
between the parties hereto and supersedes and merges all previous written and oral negotiations,
commitments, understandings and agreements relating to the subject matter hereof between the
parties hereto.

standing under the laws of its respective jurisdiction of incorporation and has
full corporate power and authority to conduct its business as presently
conducted and as proposed to be conducted by it. The Company has full corporate
power and authority to enter into and perform the Transaction Documents and to

jurisdiction, revoking, limiting or curtailing, or seeking to revoke, limit or
curtail, such power and authority or qualification.

                                       6
<PAGE>

      (b) Authorization and Noncontravention; Binding Effect. (i) The
Transaction Documents have been duly executed and delivered by the Company, and
are valid and binding obligations of the Company, enforceable in accordance with
their respective terms, except as enforcement may be limited by bankruptcy,
insolvency, moratorium or other similar laws relating to creditors' rights
generally, and except that the availability of equitable remedies, including
specific performance, is subject to the discretion of the court before which any
proceeding therefor may be brought. The execution, delivery and performance of
the Transaction Documents, the issuance and delivery of the Shares have been
duly authorized by all necessary corporate or other action of the Company. The
Board has determined, at a duly convened meeting or pursuant to a unanimous
written consent, that the issuance and sale of the Shares, the removal of the
Transfer Restriction on the Transfer Restriction Lapse Date, and the
consummation of the transactions contemplated by the Transaction Documents
(including without limitation the issuance of the Shares), are in the best
interests of the Company. The certification of designation of Series B Preferred
Stock (the "Certificate"), a form of which is attached hereto as Exhibit C, has
been duly approved by the Board and filed with the Secretary of the State of
Delware and is in full force and effect.

      (c) Valid Issuance of Shares. When issued to and paid for by the Purchaser
or converted in accordance with the terms of the Transaction Documents, the
Shares and the Common Stock into which the Preferred Stock will convert will be
duly authorized, validly issued, fully paid and nonassessable, free and clear of
all liens, and the issuance of the Shares and the Common Stock into which the
Preferred Stock will convert will not be subject to any preemptive or similar
rights that have not been waived. The Company has reserved from its duly
authorized capital stock the maximum number of securities issuable pursuant to
this Agreement.

      (d) Capitalization. As of the date of this Agreement, the authorized and
outstanding capitalization of the Company consists of (i) a total of 27,227,668
authorized shares of preferred stock, $0.01 par value per share, of which
26,227,668 shares have been designated Series A Convertible Preferred Stock,
none of which are issued and outstanding as of the date hereof, and 1,000 shares
of Series B Preferred Stock, none of which are issued and outstanding as of the
date hereof (ii) a total of 150,000,000 authorized shares of Common Stock, of
which 69,631,123 shares were issued and outstanding as of the date hereof. All
of such outstanding shares are validly issued, fully paid and nonassessable,
have been issued in compliance with all federal and state securities laws, and
none of such outstanding shares was issued in violation of any preemptive
rights, right of first refusal or similar rights to subscribe for or purchase
securities. In addition to the foregoing, as of the date hereof, warrants to
purchase a total of 667,328 shares of Common Stock were outstanding and such
shares of Common Stock were reserved for issuance, options to purchase a total
of 5,135,870 shares of Common Stock were outstanding and such shares of Common
Stock are reserved for issuance, and the Company is authorized to grant up to
1,681,497 additional shares of Common Stock pursuant to the Company Stock Option
Plans. Except as set forth in this Section 5(d), there are no other outstanding
options, warrants or similar agreements or rights for the purchase from the
Company of any shares of its

                                       7
<PAGE>

capital stock or any securities convertible into or ultimately exchangeable or
exercisable for any shares of the Company's capital stock. There are no
stockholders agreements, voting agreements or other similar agreements with
respect to the Common Stock to which the Company is a party or, to the knowledge
of the Company, between or among any of the Company's stockholders, except the
Stockholders Agreement. All the outstanding shares of capital stock or other
equity interests of each Subsidiary of the Company have been duly authorized and
validly issued, are fully paid and nonassessable and are owned by the Company
directly or indirectly through one or more wholly-owned subsidiaries (it being
expressly understood that the Company does not own all of the outstanding shares
of EverQ GmbH), free and clear of any claim, lien, encumbrance, security,
interest, restriction upon voting or transfer or any other claim of any third
party (other than with respect to EverQ GmbH).

      (e) Defaults. Neither the issuance and sale of the Shares or the
conversion of the Series B Preferred Stock pursuant to the terms and conditions
hereunder or under the Certificate nor the execution and delivery of the
Transaction Documents and the performance of the Company's obligations
thereunder will (i) violate or conflict with, result in a breach of or
constitute a default (or constitute an event that, with notice or lapse of time,
would constitute a violation or breach of or a default) under (A) the
certificate of incorporation or bylaws of the Company; (B) any decree, judgment,
order or determination of any court, governmental agency or body, or any
arbitrator having jurisdiction over the Company or any of the Company's assets;
(C) any law, rule or regulation applicable to the Company; or (D) the terms of
any material agreement by which the Company is bound or to which any property of
the Company is subject, or (ii) result in the creation or imposition of any
lien, encumbrance, claim, security interest or restriction whatsoever upon any
of the material properties or assets of the Company or an acceleration of
indebtedness pursuant to any obligation, agreement or condition contained in any
material bond, debenture, note or any other evidence of indebtedness or any
material indenture, mortgage, deed of trust or any other agreement or instrument
to which the Company is a party or by which it is bound or to which any of the
material property or assets of the Company is subject. Neither the sale of the
Shares hereunder nor the performance of the Company's other obligations under
this Agreement will result in the suspension, revocation, impairment, forfeiture
or nonrenewal of any material permit, license, authorization, right or approval
applicable to the Company, its businesses or operations or any of its assets or
properties. No consent, approval, authorization or other order of, or
registration, qualification or filing with, any regulatory body, administrative
agency, or other governmental body in the United States or any other Person is
required for the execution and delivery of the Transaction Documents and the
valid issuance and sale of the Shares or the conversion of the Series B
Preferred Stock thereunder, other than such as have been made or obtained, and
except for any post-closing securities filings or notifications required to be
made under federal or state securities laws and the Nasdaq rules. Based in part
on the representations of the Purchaser set forth in Section 6 below, the offer
and sale of the Shares to the Purchaser will be in compliance with all
applicable federal and state securities laws and the Company has made or will
make all requisite filings and has taken or will take all action necessary to

of such dates, as follows:

      (a) Organization; Good Standing; Qualification. The Purchaser is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation and has full corporate power and authority
to conduct its business as presently conducted and as proposed to be conducted
by it. The Purchaser has full corporate power and authority to enter into and

do business as a foreign corporation in each jurisdiction in which the failure

seeking to revoke, limit or curtail, such power and authority or qualification.

      (b) Authorization. The Transaction Documents will be, at Closing, duly
executed and delivered by the Purchaser, and are valid and binding obligations
of the

                                       17
<PAGE>

Purchaser, enforceable in accordance with their respective terms, except as
enforcement may be limited by bankruptcy, insolvency, moratorium or other
similar laws relating to creditors' rights generally, and except that the
availability of equitable remedies, including specific performance, is subject
to the discretion of the court before which any proceeding therefor may be
brought. The Purchaser has taken, or prior to the Closing, will have taken, all
corporate or other action required to authorize the execution and delivery of
the Transaction Documents and the performance of its obligations thereunder.

      (c) Defaults. The execution and delivery of the Transaction Documents and
the performance of the Purchaser's obligations thereunder will not (i) violate
or conflict with, result in a breach of or constitute a default (or constitute
an event that, with notice or lapse of time, would constitute a violation or
breach of or a default) under (A) the certificate of incorporation or bylaws of
the Purchaser; (B) any decree, judgment, order or determination of any court,
governmental agency or body, or any arbitrator having jurisdiction over the

applicable to the Purchaser; or (D) the terms of any material agreement by which
the Purchaser is bound or to which any property of the Purchaser is subject, or
(ii) result in the creation or imposition of any lien, encumbrance, claim,
security interest or restriction whatsoever upon any of the material properties
or assets of the Purchaser or an acceleration of indebtedness pursuant to any
obligation, agreement or condition contained in any material bond, debenture,
note or any other evidence of indebtedness or any material indenture, mortgage,
deed of trust or any other agreement or instrument to which the Purchaser is a
party or by which it is bound or to which any of the material property or assets
of the Purchaser is subject. No consent, approval, authorization or other order
of, or registration, qualification or filing with, any regulatory body,

Republic of Korea or any other Person is required for the execution and delivery
of the Transaction Documents by the Purchaser, other than such as have been made
or obtained.

      (d) Reliance Upon Purchaser's Representations. The Purchaser understands
that the issuance of the Shares hereunder has not been registered under the
Securities Act, based on the exemption from registration provided by Section
4(2) of the Securities Act and Regulation D thereunder, and that the Company's
reliance on such exemption with respect to the issuance of the Shares depends in
part on the Purchaser's representations and warranties hereunder.

      (e) Purchase Entirely for Own Account. The Purchaser is acquiring the
Shares for its own account (or for an account over which it exercises investment
discretion) for investment purposes and not with a view to the distribution
thereof within the meaning of the Securities Act, except pursuant to sales that
are registered under the Securities Act or are exempt from the registration
requirements of the Securities Act; provided, however, that, in making such
representation, the Purchaser does not agree to hold the Shares for any minimum
or specific term and reserves the right to sell, transfer or otherwise dispose
of the Shares at any time in accordance with

                                       18
<PAGE>

the provisions of this Agreement and with Federal and state securities laws
applicable to such sale, transfer or disposition.

      (f) Restricted Securities. The Purchaser understands that the Shares
constitute "restricted securities" within the meaning of Rule 144 under the
Securities Act and may not be sold, pledged or otherwise disposed of unless they
are subsequently registered under the Securities Act and applicable state
securities laws or unless an exemption from registration thereunder is
available.

      (g) Accredited Investor. The Purchaser is an "accredited investor" within
the meaning of Rule 501(a) under the Securities Act, who by reason of such
Purchaser's business and financial experience has such knowledge and experience
in financial and business matters that the Purchaser is capable of evaluating
the merits and risks of an investment in the Shares.

understands that no federal or state or other governmental agency has passed
upon or made any recommendation or endorsement with respect to the Shares.

      (i) SEC Filings. The Purchaser acknowledges that the Company may be
required to file this Agreement with the Commission under the Securities Act and
the rules thereunder and/or the Exchange Act and the rules thereunder, and to
describe the transactions contemplated by this Agreement in such filing, and
subsequent filings, and the Purchaser hereby consents to such filing; provided,
that the Company shall provide the Purchaser with a reasonable opportunity to
review and comment on any such filing.

      (j) Short Sales. To the Purchaser's knowledge, neither the Purchaser, nor
any of its affiliates, is presently the record or beneficial owner of a short
position in the Common Stock.

      (k) Receipt of Information. The Purchaser has had an opportunity to ask
questions and receive answers from the Company regarding the terms and
conditions of the issuance and sale of the Shares and the business, properties,
prospects and financial condition of the Company and to obtain any additional
information requested and has received and considered all information it deems
relevant to make an informed decision to purchase the Shares.

      (l) Legends. The Purchaser understands that any certificates evidencing
the Shares will bear substantially the following legend:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER
            THE APPLICABLE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION,
            AND MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, PLEDGED OR OTHERWISE
            DISPOSED OF EXCEPT IN COMPLIANCE

                                       19
<PAGE>

            WITH THE REQUIREMENTS OF SUCH ACT AND THE APPLICABLE SECURITIES LAWS
            OF ANY STATE OR OTHER JURISDICTION."

Certificates evidencing the Shares shall not contain any legend (i) following
any sale of such Shares, as applicable, pursuant to Rule 144 or pursuant to an
effective registration statement, as certified by the Purchaser to the Company,
(ii) if such Shares, as applicable, are eligible for sale under Rule 144(k), or
(iii) if such legend is not required under applicable requirements of the
Securities Act (including judicial interpretations and pronouncements issued by
the staff of the Commission). The Company agrees that at such time as such
legend is no longer required under this Section 5(l), the Company shall cause
its counsel to promptly issue a legal opinion addressed to the Company's
transfer agent if required by the Company's transfer agent to effect the removal
of the legend hereunder as and when the Purchaser so requests. The Company
agrees that at such time as such legend is no longer required under this Section
5(l), it will, promptly following the delivery by the Purchaser to the Company
or the Company's transfer agent of a certificate representing Shares issued with
a restrictive legend, deliver or cause to be delivered to the Purchaser a
certificate representing such Shares that is free from all restrictive and other
legends.

Transaction Documents or the transactions contemplated thereby without the prior
consent of the other party, provided that each Purchaser shall have a reasonable
opportunity to review and comment on any such press release or Form 8-K prior to
the issuance or filing thereof. Notwithstanding the foregoing, the Company shall
not publicly disclose the name of the Purchaser, or include the name of the
Purchaser in any filing with the Commission, without the prior written consent
of the Purchaser, except (i) as required by the Securities Act in connection
with the registration statement(s) contemplated by the Stockholders Agreement
and (ii) to the extent that such disclosure is required by applicable laws,
rules or regulations, in which case the Company shall provide the Purchaser with
prior written notice of such disclosure.

      (f) The parties hereto shall take all actions necessary to file as soon as
practicable all notifications, filings and other documents required to obtain
all governmental authorizations, approvals, consents or waivers under the HSR
Act to permit the conversion of the Series B Preferred Stock held by the
Purchaser into Common Stock, and to respond promptly to any inquiries received
from the Federal Trade Commission, the Antitrust Division of the Department of
Justice or any other governmental entity in connection therewith.

      Section 9. Termination.

      (a) Termination. This Agreement may be terminated prior to the Closing as
follows:

            (i) at any time on or prior to the Closing Date, by mutual written
      consent of the Company and the Purchaser;

            (ii) at the election of the Company or the Purchaser by written
      notice to the other party hereto after 5:00 p.m., New York time, on May
      30, 2007, if the Closing shall not have occurred on or prior to such date,
      unless such date is extended by the mutual written consent of the Company
      and the Purchaser; provided, however, that the right to terminate this
      Agreement under this Section 9(a)(ii) shall not be available to any party
      whose breach of any representation, warranty, covenant or agreement under
      this Agreement has been the cause of, or resulted in, the failure of the
      Closing to occur on or before such date.

            (iii) at the election of the Company, if there has been a material
      breach of any representation, warranty, covenant or agreement on the part
      of the Purchaser contained in this Agreement, which breach has not been
      cured within fifteen (15) Business Days of notice to the Purchaser of such
      breach; or

            (iv) at the election of the Purchaser, if there has been a material
      breach of any representation, warranty, covenant or agreement on the part
      of the Company contained in this Agreement, which breach has not been
      cured within fifteen (15) Business Days of notice to the Company of such
      breach.

If this Agreement so terminates, it shall become null and void and have no
further force or effect, except as provided in Section 10(b) below.

            (b) Survival. If this Agreement is terminated and the transactions
      contemplated hereby are not consummated as described above, this Agreement
      shall become void and of no further force and effect, except for the
      provisions of Section 10(a); provided, however, that (i) none of the
      parties hereto shall have any liability in respect of a termination of
      this Agreement pursuant to Section 9(a)(i) or Section 9(a)(ii), and (ii)
      nothing shall relieve any of the parties from liability for actual damages
      resulting from a termination of this Agreement pursuant to Section
      9(a)(iii) or Section 9(a)(iv); and provided, further, that none of the
      parties hereto shall have any liability for speculative, indirect or
      unforeseeable damages or lost profits resulting from any legal action
      relating to any termination of this Agreement.

            Section 10. Survival of Representations, Warranties and Covenants;
      Indemnification.

            (a) Survival of Representations, Warranties and Covenants. All of
      the representations and warranties made herein shall survive the execution
      and delivery of

                                       24
<PAGE>

      this Agreement until twelve (12) months following the Closing Date, except
      for Section 5(m), which shall survive until the later to occur of (i) the
      lapse of the statute of limitations with respect to the assessment of any
      tax to which such representation and warranty relates (including any
      extensions or waivers thereof) and (ii) sixty (60) days after the final
      administrative or judicial determination of the taxes to which such
      representation and warranty relates, and no claim with respect to Section
      5(m) may be asserted thereafter with the exception of claims arising out
      of any fact, circumstance, action or proceeding to which the party
      asserting such claim shall have given notice to the other parties to this
      Agreement prior to the termination of such period of reasonable belief
      that a tax liability will subsequently arise therefrom. Except as
      otherwise provided in this Agreement, all such representations,
      warranties, covenants and agreements shall inure to the benefit of the
      parties (subject to Section 9(b) below) and their respective successors
      and assigns and to their transferees of the Shares.

            (b) Indemnification.

                  (i) The Company agrees to defend, indemnify and hold harmless
            the Purchaser, its Subsidiaries, its Affiliates and direct and
            indirect partners (including partners of partners and stockholders
            and members of partners), members, stockholders, directors,
            officers, employees and agents and each person who controls any of
            them within the meaning of Section 15 of the Securities Act or
            Section 20 of the Exchange Act (collectively, the "Purchaser
            Indemnified Parties" and each a "Purchaser Indemnified Party"),
            harmless from and against any and all Losses which may be sustained
            or suffered by any such Purchaser Indemnified Party in any manner
            based upon, relating to or arising out of (a) any untrue
            representation, misstatement, material omission, breach of warranty
            or failure to perform any covenants or agreement by the Company
            contained herein or in any Transaction Document or (b) any action
            instituted against a Purchaser Indemnified Party by any stockholder
            of the Company who is not an Affiliate of such Purchaser Indemnified
            Party, with respect to any of the transactions contemplated by the
            Transaction Documents (unless such action is based upon a breach of
            such Purchaser Indemnified Party's representation, warranties or
            covenants under the Transaction Documents or any agreements or
            understandings such Purchaser Indemnified Party may have with any
            such stockholder or any violations by such Purchaser Indemnified
            Party of state or federal securities laws or any conduct by such
            Purchaser Indemnified Party which constitutes fraud, gross
            negligence, willful misconduct or malfeasance). The Company will
            also advance expenses as incurred to the fullest extent permitted
            under applicable law; provided, however, that the Purchaser
            Indemnified Party provides an undertaking to repay such advances to
            Company if it is ultimately determined that such Purchaser
            Indemnified Party is not entitled to indemnification. The Purchaser
            Indemnified Party and the Company will cooperate in the defense of
            any such matter.

                  (ii) A Purchaser Indemnified Party shall give written notice
            of a claim for indemnification under this Section 10 to the Company
            promptly after

                                       25
<PAGE>

            receipt of any written claim by any third party and in any event not
            later than twenty (20) Business Days after receipt of any such
            written claim (or not later than ten (10) Business Days after the
            receipt of any such written claim in the event such written claim is
            in the form of a formal complaint filed with a court of competent
            jurisdiction and served on such Purchaser Indemnified Party),
            specifying in reasonable detail the amount, nature and source of the
            claim, and including therewith copies of any notices or other
            documents received from third parties with respect to such claim;
            provided, however, that failure to give such notice shall not limit
            the right of a Purchaser Indemnified Party to recover indemnity or
            reimbursement except to the extent that the Company suffers any
            material prejudice or material harm with respect to such claim as a
            result of such failure. The Purchaser Indemnified Party shall also
            provide the Company with such further information concerning any
            such claims as the Company may reasonably request by written notice.

                  (iii) Within five (5) Business Days after receiving notice of
            a claim for indemnification or reimbursement, the Company shall, by
            written notice to the Purchaser Indemnified Party, either (A)
            concede or deny liability for the claim in whole or in part, or (B)
            in the case of a claim asserted by a third party, advise that the
            matters set forth in the notice are, or will be, subject to contest
            or legal proceedings not yet finally resolved. If the Company
            concedes liability in whole or in part, it shall, within twenty (20)
            Business Days of such concession, pay the amount of the claim to the
            Purchaser Indemnified Party to the extent of the liability conceded.
            Any such payment shall be made in immediately available funds equal
            to the amount of such claim so payable. If the Company denies
            liability in whole or in part or advises that the matters set forth
            in the notice are, or will be, subject to contest or legal
            proceedings not yet finally resolved, then the Company shall make no
            payment (except for the amount of any conceded liability payable as
            set forth above) until the matter is resolved by a final judgment
            (not subject to any appeal) of a court or other tribunal of
            competent jurisdiction.

                  (iv) In the case of any third party claim, if within five (5)
            Business Days after receiving the notice described in the preceding
            Section 10(a), the Company (A) gives written notice to the Purchaser
            Indemnified Party stating that the Company disputes and intends to
            defend against such claim, liability or expense at the Company's own
            cost and expense and (B) provides assurance reasonably acceptable to
            such Purchaser Indemnified Party that such indemnification will be
            paid fully and promptly if required and such Purchaser Indemnified
            Party will not incur cost or expense during the proceeding, then
            counsel for the defense shall be selected by the Company (subject to
            the consent of such Purchaser Indemnified Party which consent shall
            not be unreasonably withheld) and the Company shall not be required
            to make any payment to the Purchaser Indemnified Party with respect
            to such claim, liability or expense as long as the Company is
            conducting a good faith and diligent defense at its own expense;
            provided, however, that the assumption of defense of any such
            matters by the Company shall relate solely to the claim, liability
            or expense that is

                                       26
<PAGE>

            subject or potentially subject to indemnification. If the Company
            assumes such defense in accordance with the preceding sentence, it
            shall have the right, with the consent of such Purchaser Indemnified
            Party, which consent shall not be unreasonably withheld, to settle
            all indemnifiable matters related to claims by third parties which
            are susceptible to being settled provided the Company's obligation
            to indemnify such Purchaser Indemnified Party therefor will be fully
            satisfied only by payment of money by the Company pursuant to a
            settlement which includes a complete release of such Purchaser
            Indemnified Party. The Company shall keep such Purchaser Indemnified
            Party apprised of the status of the claim, liability or expense and
            any resulting suit, proceeding or enforcement action, shall furnish
            such Purchaser Indemnified Party with all documents and information
            that such Purchaser Indemnified Party shall reasonably request and
            shall consult with such Purchaser Indemnified Party prior to acting
            on major matters, including settlement discussions. Notwithstanding
            anything herein stated, such Purchaser Indemnified Party shall at
            all times have the right to fully participate in such defense at its
            own expense directly or through counsel; provided, however, if the
            named parties to the action or proceeding include both the Company
            and one or more Purchaser Indemnified Parties and representation of
            such parties by the same counsel would be inappropriate under
            applicable standards of professional conduct, the reasonable expense
            of separate counsel for all Purchaser Indemnified Parties shall be
            paid by the Company, provided that the Company shall be obligated to
            pay for only one counsel for all Purchaser Indemnified Parties in
            any jurisdiction. If no such notice of intent to dispute and defend
            is given by the Company, or if such diligent good faith defense is
            not being or ceases to be conducted, such Purchaser Indemnified
            Party may undertake the defense of (with counsel selected by such
            Purchaser Indemnified Party), and shall have the right to compromise
            or settle, such claim, liability or expense (exercising reasonable
            business judgment) with the consent of the Company, which consent
            shall not be unreasonably withheld. If such claim, liability or
            expense is one that by its nature cannot be defended solely by the
            Company, then such Purchaser Indemnified Party shall make available
            all information and assistance that the Company may reasonably
            request and shall cooperate with the Company in such defense.

      Section 11. Miscellaneous.

      (a) Entire Agreement; Amendments; Waivers. The terms and conditions of the
Transaction Documents represent the entire agreement between the parties with
respect to the subject matter hereof and thereof, and supersede any prior
agreements or understandings, whether written or oral, between the parties
respecting such subject matter. No provision of this Agreement may be waived or
amended except in a written instrument signed, in the case of an amendment, by
the Company and the Purchaser or, in the case of a waiver, by the party against
whom enforcement of any such waiver is sought. No course of dealing between or
among any of the parties hereto and no delay on the part of any party hereto in
exercising any rights hereunder or thereunder shall operate as a waiver of the
rights hereof and thereof. No waiver of any default with

                                       27
<PAGE>

respect to any provision, condition or requirement of this Agreement shall be
deemed to be a continuing waiver in the future or a waiver of any subsequent
default or a waiver of any other provision, condition or requirement hereof, nor
shall any delay or omission of either party to exercise any right hereunder in
any manner impair the exercise of any such right.

      (b) Successors and Assigns. This Agreement inures to the benefit of and is
binding upon the parties hereto and their respective successors, and no other
person has any right or obligation hereunder. The Purchaser may not assign this
Agreement or any rights or obligations hereunder, other than to Affiliates of
the Purchaser, without the prior written consent of the Company, such consent
not to be unreasonably withheld, provided that any permitted transferee shall
agree in writing to be bound, with respect to the transferred Shares, by the
provisions hereof that apply to the Purchaser. The Company may not assign this
Agreement or any rights or obligations hereunder without the prior written
consent of the Purchaser, except pursuant to a merger, recapitalization or other
business combination transaction in which the surviving entity agrees in writing
to assume all of the covenants, liabilities and obligations of the Company
hereunder. Any assignment contrary to the terms hereof is null and void and of
no force or effect. Notwithstanding the foregoing, nothing in this Agreement is
intended to give any person not named herein the benefit of any legal or
equitable right, remedy or claim under this Agreement, except as expressly
provided herein.

      (c) Governing Law. THIS AGREEMENT SHALL BE DEEMED TO BE A CONTRACT MADE
UNDER, AND SHALL BE CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK, WITHOUT GIVING EFFECT TO CONFLICT OF LAWS PRINCIPLES THEREOF. Each party
hereby irrevocably submits to the non-exclusive jurisdiction of the federal
courts sitting in the City of New York in the borough of Manhattan for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby, and hereby irrevocably waives, and agrees not
to assert in any suit, action or proceeding, any claim that it is not personally
subject to the jurisdiction of any such court, that such suit, action or
proceeding is brought in an inconvenient forum or that the venue of such suit,
action or proceeding is improper. Each party hereby irrevocably waives personal
service of process and consents to process being served in any such suit, action
or proceeding by mailing a copy thereof to such party at the address in effect
for notices to it under this Agreement and agrees that such service shall
constitute good and sufficient service of process and notice thereof. Nothing
contained herein shall be deemed to limit in any way any right to serve process
in any manner permitted by law.

      (d) Remedies. It is specifically understood and agreed that any breach of
the provisions of the Transaction Documents by any party subject hereto will
result in irreparable injury to the other parties hereto, that the remedy at law
alone will be an inadequate remedy for such breach, and that, in addition to any
other remedies which they may have, such other parties may enforce their
respective rights by actions for specific performance (to the extent permitted
by law) without the necessity of showing economic loss or the posting of any
bond.

                                       28
<PAGE>

      (e) Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such a manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be deemed
prohibited or invalid under such applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, and such
prohibition or invalidity shall not invalidate the remainder of such provision
or the other provisions of this Agreement.

      (f) Counterparts. This Agreement may be executed simultaneously in any
number of counterparts, each of which when so executed and delivered shall be
taken to be an original; but such counterparts shall together constitute but one
and the same document. The Transaction Documents may be executed and delivered
by facsimile transmission.
