INCREASE"). The amount of the Capital Increase shall be an amount (or its
Renminbi equivalent) equal to the difference between the total amount of the

to the prior written approval by the Series B Nominee (as defined in the
Shareholders Agreement), which approval shall not be unreasonably withheld,

          (a) For the purpose of securing satisfaction by the Warrantors of
certain conditions subsequent set forth in Section 1.06(c) (the "CONDITIONS
SUBSEQUENT"), the Warrantors and the Investors (other than the Advance Payment

Investors agree that the Escrow Amount and the Escrow Share Certificates shall

the Escrow Agreement. For the avoidance of doubt, the Shares issued to the
Advance Payment Investors shall not be subject to the provisions of this Section
1.06.

          (b) The Escrow Amount and the Escrow Share Certificates shall be held
in an escrow by the Escrow Agent subject to the terms of the Escrow Agreement
until the satisfaction or waiver of the Conditions Subsequent, upon which the
Escrow Amount (together with any accrued interest paid by the Escrow Agent)
shall be immediately released by the Escrow Agent to the Company as otherwise
provided in Section 1.03 and the Escrow Share Certificates shall be immediately
released by the Escrow Agent to the Investors as otherwise provided in Section
1.04; provided that, in the event that this Agreement is terminated by the Lead

by the Escrow Agent to the Investors, and the Escrow Share Certificates shall be
returned to the Company, each pursuant to Section 8.02(b). For the avoidance of
doubt, upon the return of the Escrow Share Certificates, the Investors shall not
be entitled to any right to or interest in the Escrow Shares evidenced by such
Escrow Share Certificates.


                                       4



          (c) Unless otherwise waived by the Lead Series B Shareholder, the
Conditions Subsequent shall be deemed to be satisfied when the Company shall

Company and Baoding Tianwei Baobian Electrics Co., Ltd (the "JV CONTRACT
AMENDMENT") and (y) an amendment to the articles of association of Tianwei

the JV Contract Amendment, the JV Article Amendment and the Capital Increase;
and (iii) the Shareholder Loan shall have been funded by the Company to Tianwei

of the State Administration of Foreign Exchange.

          (d) Each Investor (other than an Advance Payment Investor) hereby
appoints the Lead Series B Shareholder as its representative with respect to the
negotiation, execution and performance of the Escrow Agreement, and the Lead
Series B Shareholder accepts such appointment. The Lead Series B Shareholder,
acting in accordance with this Agreement, shall have the authority and power to
act on behalf of other Investors (other than the Advance Payment Investors) with
respect to the Escrow Agreement or other rights or obligations arising from and
taken pursuant to the Escrow Agreement, provided that such actions do not
increase or disproportionately affect an Investor's obligations hereunder in
regards to the obligations of all Investors hereunder. Each Investor (other than
an Advance Payment Investor) shall be bound by all actions taken by the Lead
Series B Shareholder in accordance with this Agreement, in connection with the
Escrow Agreement. Each of the Investors (other than the Lead Series B
Shareholder and the Advanced Payment Investors) agrees, severally and not
jointly, to indemnify, defend and hold harmless the other Lead Series B
Shareholder to the fullest extent permitted by law from and against any and all
Losses of the Lead Series B Shareholder resulting from or arising out of the
Lead Series B Shareholder's action on behalf of other Investors with respect to
the Escrow Agreement or other rights or obligations arising from and taken
pursuant to the Escrow Agreement in the absence of willful misconduct or bad
faith on the part of the Lead Series B Shareholder, provided, further that, such
Losses shall be borne pro rata by each of the Investors (including the Lead
Series B Shareholder) in proportion to such Investor's applicable Escrow Amount.

          SECTION 1.07. Further Assurances. At any time or from time to time
after the Closing, each party hereto shall, at the expense of the party making
such request, execute and deliver such other documents and instruments, provide
such materials and information and take such other actions as may reasonably be

          (a) Following the Closing, subject to paragraphs (c) and (d) of this
Section, Section 7.03 and the other Sections of this Article VII, the Warrantors

harmless from and against, any and all Losses suffered, incurred or sustained by

any breach of representation or warranty or non-fulfillment of or failure to
perform any covenant or agreement on the part of the Warrantors made in this
Agreement.

          (b) Notwithstanding anything to the contrary contained in this
Agreement, no amounts of indemnity shall be payable by the Warrantors as a
result of any Losses arising under paragraph (a) of this Section 7.01:

               (i) with respect to any claim, unless and until the aggregate

entire amount of Losses suffered by it subject to the terms and conditions of
Section 7.01;

               (ii) with respect to any Investor, to the extent it arises from
or was caused by actions taken by such Investor or any of its Affiliates; or

               (iii) with respect to any Investor, to the extent that such
Investor had been compensated for such Loss.

          (c) Notwithstanding anything to the contrary contained in this
Agreement, the Warrantors shall, in no circumstance, be obligated hereunder to
indemnify any Investor in respect of any and all Losses in the aggregate in an
amount in excess of the sum of (i) the Purchase Price paid by such Investor and
(ii) an amount representing 12% of the Purchase Price paid by such Investor, as
computed on an annualized basis.


                                       23



          (d) Notwithstanding anything to the contrary contained in this
Agreement, this Article VII shall survive any termination of this Agreement.

          SECTION 7.02. Method of Asserting Claims. All claims for
indemnification by any Indemnified Party under Section 7.01 must be asserted and
resolved as follows:

          (a) In the event any claim or demand in respect of which an
Indemnified Party might seek indemnity under Section 7.01 is asserted against or
sought to be collected from such Indemnified Party by a Person other than the
Warrantors or any of their respective Affiliates (a "THIRD PARTY CLAIM"), the
Indemnified Party shall deliver a Claim Notice with reasonable promptness to the
Indemnifying Party. The Indemnifying Party shall notify the Indemnified Party as
soon as practicable within the Dispute Period whether the Indemnifying Party
disputes its liability to the Indemnified Party under Section 7.01 and whether
the Indemnifying Party desires, at its sole cost and expense, to defend the
Indemnified Party against such Third Party Claim.

               (i) If the Indemnifying Party notifies the Indemnified Party
within the Dispute Period that the Indemnifying Party desires to defend the
Indemnified Party with respect to the Third Party Claim pursuant to this Section
7.02(a), then the Indemnifying Party shall have the right to defend, at the sole
cost and expense of the Indemnifying Party, such Third Party Claim by all
appropriate proceedings, which proceedings shall be vigorously and diligently
prosecuted by the Indemnifying Party to a final conclusion or shall be settled
at the discretion of the Indemnifying Party (but only with the consent of the
Indemnified Party, which consent shall not be unreasonably withheld or delayed
in the case of any settlement that provides for any relief other than the
payment of monetary damages as to which the Indemnified Party shall be
indemnified in full). The Indemnifying Party shall have full control of such
defense and proceedings, including (except as provided in the immediately
preceding sentence) any settlement thereof, except that:

                    (x) the Indemnified Party may, at the sole cost and expense
of the Indemnified Party, at any time prior to the Indemnifying Party's delivery
of the notice referred to in the first sentence of this clause (i), file any
motion, answer or other pleadings or take any other action that the Indemnified
Party reasonably believes to be necessary or appropriate to protect its
interests and not prejudicial to the Indemnifying Party (it being understood and
agreed that, except as provided in clause (ii) below, if an Indemnified Party
takes any such action that is prejudicial and causes a final adjudication that
is adverse to the Indemnifying Party, the Indemnifying Party shall be relieved
of its obligations hereunder with respect to the portion of such Third Party
Claim prejudiced by the Indemnified Party's action); and

                    (y) if requested by the Indemnifying Party, the Indemnified
Party shall, at the sole cost and expense of the Indemnifying Party, cooperate
with the Indemnifying Party and its counsel in contesting any Third Party Claim
that the


                                       24



Indemnifying Party elects to contest, or, if appropriate and related to the
Third Party Claim in question, in making any counterclaim against the Person
asserting the Third Party Claim, or any cross-complaint against any Person
(other than the Indemnified Party or any of its Affiliates).

                         The Indemnified Party may retain separate counsel to
represent it in, but not control, any defense or settlement of any Third Party
Claim controlled by the Indemnifying Party pursuant to this clause (i), and the
Indemnified Party shall bear its own costs and expenses with respect to such
separate counsel except as provided in the preceding sentence. Notwithstanding
the foregoing, the Indemnified Party may retain or take over the control of the
defense or settlement of any Third Party Claim the defense of which the
Indemnifying Party has elected to control if the Indemnified Party irrevocably
waives its right to indemnity under Section 7.01 with respect to such Third
Party Claim.

               (ii) If the Indemnifying Party fails to notify the Indemnified
Party within the Dispute Period that the Indemnifying Party desires to defend
the Third Party Claim pursuant to this Section 7.02(a), then the Indemnified
Party shall have the right to defend, at the sole cost and expense of the
Indemnifying Party, the Third Party Claim by all appropriate proceedings, which
proceedings shall be vigorously and diligently prosecuted by the Indemnified
Party to a final conclusion or shall be settled at the discretion of the
Indemnified Party (with the consent of the Indemnifying Party, which consent
shall not be unreasonably withheld or delayed). The Indemnified Party shall have
full control of such defense and proceedings, including (except as provided in
the immediately preceding sentence) any settlement thereof; provided, however,
that:

                    (x) if requested by the Indemnified Party, the Indemnifying
Party shall, at the sole cost and expense of the Indemnifying Party, cooperate
with the Indemnified Party and its counsel in contesting any Third Party Claim
which the Indemnified Party is contesting, or, if appropriate and related to the
Third Party Claim in question, in making any counterclaim against the Person
asserting the Third Party Claim, or any cross-complaint against any Person
(other than the Indemnifying Party or any of its Affiliates);

                    (y) notwithstanding the foregoing provisions of this clause
(ii), if the Indemnifying Party has notified the Indemnified Party within the
Dispute Period that the Indemnifying Party disputes its liability hereunder to
the Indemnified Party with respect to such Third Party Claim and if such dispute
is resolved in favor of the Indemnifying Party in the manner provided in clause
(iii) below, the Indemnifying Party shall not be required to bear the costs and
expenses of the Indemnified Party's defense pursuant to this clause (ii) or of
the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all reasonable costs and expenses incurred by the Indemnifying Party in
connection with such litigation; and


                                       25



                    (z) the Indemnifying Party may retain separate counsel to
represent it in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this clause (ii), and the Indemnifying Party shall
bear its own costs and expenses with respect to such participation.

               (iii) If the Indemnifying Party notifies the Indemnified Party
that it does not dispute its liability to the Indemnified Party with respect to
the Third Party Claim under Section 7.01 or fails to notify the Indemnified
Party within the Dispute Period whether the Indemnifying Party disputes its
liability to the Indemnified Party with respect to such Third Party Claim, the
Loss arising from such Third Party Claim shall, subject to the provisions of
Section 7.01(c), be conclusively deemed a liability of the Indemnifying Party
under Section 7.01 and the Indemnifying Party shall, subject to the provisions
of Section 7.01(c), pay the amount of such Loss to the Indemnified Party on
demand following the final determination thereof. If the Indemnifying Party has
timely disputed its liability with respect to such claim, the Indemnifying Party
and the Indemnified Party shall proceed in good faith to negotiate a resolution
of such dispute and, if not resolved through negotiations, such dispute shall be
resolved in accordance with the dispute resolution provisions in Section 10.10.

          (b) In the event of a claim by any Indemnified Party under Section
7.01 against any Indemnifying Party that does not involve a Third Party Claim,
the Indemnified Party shall deliver an Indemnity Notice with reasonable
promptness to the Indemnifying Party. If the Indemnifying Party notifies the
Indemnified Party that it does not dispute the claim described in such Indemnity
Notice or fails to notify the Indemnified Party within the Dispute Period
whether the Indemnifying Party disputes the claim described in such Indemnity
Notice, the Loss arising from the claim specified in such Indemnity Notice
shall, subject to the provisions of Section 7.01(c), be conclusively deemed a
liability of the Indemnifying Party under Section 7.01 and the Indemnifying
Party shall, subject to the provisions of Section 7.01(c), pay the amount of
such Loss to the Indemnified Party on demand following the final determination
thereof. If the Indemnifying Party has timely disputed its liability with
respect to such claim, the Indemnifying Party and the Indemnified Party shall
proceed in good faith to negotiate a resolution of such dispute, and if not
resolved through negotiations, such dispute shall be resolved in accordance with
the dispute resolution provisions in Section 10.10.

          SECTION 7.03. Exclusivity. After the Closing, except in the event of
fraud or willful breach of representations, warranties or covenants herein, the
indemnities set forth in this Article VII shall be the sole and exclusive
remedies of each Investor and its respective officers, directors, employees,
agents and Affiliates for any breach of representation or warranty or
nonfulfillment of or failure to perform any covenant or agreement made in this
Agreement, and the parties shall not be entitled to a rescission of this
Agreement or to any further indemnification rights or claims of any nature
whatsoever in respect thereof, all of which the parties hereto hereby waive. No
Person who was an officer, director or stockholder of the Company or any of the
Subsidiaries prior to the Closing or any of their respective Affiliates shall
have any liability to make any payment in respect of any breach of any
representation or warranty


                                       26



or non-performance of any covenant or agreement made in this Agreement, except
for the Company's indemnification obligations under this Article VII.

          SECTION 7.04. No Consequential Damages. Anything herein to the
contrary notwithstanding, no party shall be liable under this Agreement or with
respect to the transactions contemplated hereby for any consequential,
exemplary, punitive, special, indirect or incidental damages, including loss of
profits or revenue or any multiple of damages.

          SECTION 7.05. Limitation of Liability. No recourse shall be had for
any claim based on or otherwise in respect of this Agreement or the transactions
contemplated hereby against any Person other than the Warrantors or the
Investors.

transactions contemplated hereby may be abandoned:

          (a) at any time before the Closing, by mutual written agreement of the
Company and the Investors; or

Conditions Subsequent shall have not been satisfied or waived by March 31, 2007;

          SECTION 8.02. Effect of Termination. (a) Subject to paragraph (b)
below, if this Agreement is validly terminated pursuant to Section 8.01, this
Agreement shall forthwith become null and void, and there shall be no liability
or obligation on the part of the Company or any Investor (or any of their
respective officers, directors, employees, agents or other Representatives or
Affiliates) under this Agreement or in connection with the transactions
contemplated hereby, except that such termination shall not relieve any
breaching party from liability hereunder from willful breach of any
representation or warranty contained herein or any breach of any covenant or
agreement contained herein.

          (b) If this Agreement is validly terminated pursuant to Section
8.01(b), within five (5) Business Days after receipt of such written request
from the Lead Series B Investor, the Escrow Agent shall (i) release the Escrow
Amount (together with any accrued interest paid thereon by the Escrow Agent) to
the bank accounts designated by the Lead Series B Investor in writing and (ii)
return the Escrow Share Certificates to the Company. Immediately upon the return
by the Escrow Agent of the Escrow Amount (together with any accrued interest
paid by the Escrow Agent) to each Investor, such Investor shall no longer be a
shareholder of the Company with respect to the Escrow Shares and shall not have
any rights, interests or claims with respect to the Company as a shareholder of
the Company with respect to the Escrow Shares.

                                    EXHIBIT E

               ADDITIONAL INVESTOR REPRESENTATIONS AND WARRANTIES

1.   The Investor understands that the Shares have not been registered under the
     Securities Act and may only be sold or otherwise transferred in accordance
     with the restrictions and conditions set forth in this Agreement and the
     Shareholders Agreement.

2.   The Investor understands that purchasing the Shares (the "TRANSACTION")
     involves a high degree of risk and that the Shares are a speculative
     investment.

3.   The Investor (a) has consulted with its own legal, regulatory, tax,
     business, investment, financial and accounting advisers in connection
     herewith to the extent it has deemed necessary, (b) has conducted its own
     due diligence on the Company, its subsidiaries and the Transaction, and (c)
     has made its own investment decisions based upon its own judgment, due
     diligence and advice from such advisers as it has deemed necessary.

4.   The Investor has such knowledge and experience in financial, business and
     international investment matters that it is capable of evaluating the
     merits and risks of purchasing the Shares, and has had the opportunity to
     ask questions of, and receive answers and request additional information
     from the Company.

5.   The Investor has the ability to bear the economic risk of the Transaction,
     has adequate means of providing for its current and contingent needs, has
     no need for liquidity with respect to its investment in the Shares, and is
     able to sustain a complete loss in connection with the Transaction.

6.   The Investor acknowledges, represents and agrees:

     (i)  that it is an accredited investor ("AI") as defined in Rule 501(a) of
          the Securities Act, purchasing the Shares for its own account or for
          the account of one or more AIs as defined in Rule 501(a) of the
          Securities Act;

     (ii) that it is aware, and each beneficial owner of the Shares has been
          advised, that any sale to it is being made in reliance on an exemption
          from the registration requirements of the Securities Act;

     (iii) that no securities issuable upon conversion of the Shares (the
          "CONVERSION SHARES") have been registered under the Securities Act or
          any applicable U.S. state securities laws, that the Shares and the
          Conversion Shares are "restricted securities" within the meaning of
          Rule 144(a)(3) under the Securities Act and that no Shares or
          Conversion Shares may be offered or sold within the United States or
          to, or for the account or benefit of, U.S. persons (as defined in
          Regulation S of the Securities Act) except as set forth in (iv) below;

     (iv) if in the future it decides to resell, pledge or otherwise transfer
          the Shares or the Conversion Shares or any beneficial interests
          therein, it will do so, only (a) inside the United States to a person
          whom the Investor reasonably believes is a QIB



          pursuant to an exemption from registration under the Securities Act,
          (b) outside the United States to a person other than a U.S. person (as
          defined in Regulation S of the Securities Act) in compliance with
          Regulation S of the Securities Act, (c) pursuant to another exemption
          from registration under the Securities Act (if available) or (d)
          pursuant to an effective registration statement under the Securities
          Act, in each case, in accordance with the Securities Act and
          applicable laws of the states, territories and possession of the
          Untied States governing the offer and sale of securities;

     (v)  it will, and will require each subsequent holder of the Shares or the
          Conversion Shares to, notify any purchaser of an interest in the
          Shares or the Conversion Shares of the resale restrictions referred to
          in paragraphs (iii) and (iv) above, if then applicable;

     (vi) that the Conversion Shares will bear a legend setting forth the resale
          restrictions referred to in paragraphs (iii) and (iv) above; and

     (vii) on each day from the date on which it acquires the Shares, through
          and including the date on which it disposes of its interests in such
          Shares, either that (a) it is not an "employee benefit plan" as
          defined in Section 3(3) of ERISA, subject to Title I of ERISA, a
          "plan" (defined in Section 4975(e)(1) of the Code, subject to Section
          4975 of the Code (including without limitation, an individual
          retirement account), an entity whose underlying assets include the
          assets of any such employee benefit plan or plan by reason of
          Department of Labor Regulation section 2510.3-10 or otherwise, or a
          governmental or church plan which is subject to any federal, state or
          local law that is substantially similar to the provisions of Section
          406 of ERISA or Section 4975 of the Code or (b) its purchase, holding
          and disposition of such Notes will not result in a prohibited
          transaction under Section 406 of ERISA or Section 4975 of the Code
          (or, in the case of a governmental or church plan, any substantially
          similar federal, state or local law) unless an exemption is available
          with respect to such transactions and all the conditions of such
          exemption have been satisfied.

7.   The Investor understands that no action has been taken to permit an
     offering of the Shares or the Conversion Shares in any jurisdiction; the
     Investor will not offer or sell any of the Shares or the Conversion Shares
     which may be acquired by it in any jurisdiction or in any circumstances in
     which such offer or sale is not authorised or to any person to whom it is
     unlawful to make such offer, sale or invitation except under circumstances
     that will result in compliance with any applicable laws and/or regulations.

8.   The Investor's purchase of the Shares is lawful under the securities laws
     of the jurisdiction in which it accepts the offer to purchase the Shares.
