     2. RESTRICTIONS ON TRANSFER; RESTRICTIVE LEGENDS.

     2.1 RESTRICTIONS ON TRANSFER; COMPLIANCE WITH SECURITIES LAWS.

          (a) This Warrant and the Warrant Shares issued upon the exercise of
the Warrant are not assignable or transferable except this Warrant (and all
rights hereunder) and the Warrant Shares issued upon the exercise of the Warrant
may be assigned or transferred, in whole or in part, to an Affiliate of the
Warrantholder, which shall thereafter be deemed to be the Warrantholder for all
purposes herein, provided, however, the Warrant Shares issued upon the exercise
of the Warrant may not be transferred or assigned in whole or in part without
compliance with all applicable federal and state securities laws by the
transferor and transferee.

          (b) The Warrantholder, by acceptance hereof, acknowledges that this
Warrant and the Warrant Shares to be issued upon exercise hereof are being
acquired solely for the Warrantholder's own account and not as a nominee for any
other party, and for investment, and that the Warrantholder will not offer, sell
or otherwise dispose of any Warrant Shares to be issued upon exercise hereof
except under circumstances that will not result in a violation of the Securities
Act or any state securities laws. Upon exercise of this Warrant, the
Warrantholder shall, if requested by the Company, confirm in writing, in a form
satisfactory to the Company, that the Warrant Shares so purchased are being
acquired solely for the Warrantholder's own account and not as a nominee for any
other party, for investment, and not with a view toward distribution or resale.
The Warrantholder represents and warrants to the Company that the Warrantholder
is an "accredited investor" as that term is defined in Rule 501(a) of Regulation
D promulgated under the 1933 Act. The Warrantholder understands that the Warrant
and any Warrant Shares acquired upon exercise of this Warrant are being offered
and sold to the Warrantholder in reliance on specific exemptions from the
registration requirements of the United States federal and state securities laws
and that the Company is relying in part upon the truth and accuracy of, and the
Warrantholder's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of the Warrantholder set forth herein in
order to determine the availability of such exemptions and the eligibility of
the Warrantholder to initially acquire the Warrant Shares.

     2.2 RESTRICTIVE LEGENDS. This Warrant shall (and each Warrant issued in
substitution for this Warrant issued pursuant to Section 4 shall) be stamped or
otherwise imprinted with a legend in substantially the following form:

          "THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS
     WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED (THE "SECURITIES ACT"), OR APPLICABLE STATE SECURITIES LAWS AND
     HAVE BEEN ISSUED PURSUANT TO AN EXEMPTION THEREFROM. EXCEPT AS PERMITTED
     UNDER APPLICABLE FEDERAL AND STATE SECURITIES LAWS, THE WARRANT AND ANY
     SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT MAY NOT BE SOLD OR
     OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT

                                      -3-

<PAGE>

     UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, OR AN
     OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS NOT
     REQUIRED."

Except as otherwise permitted by this Section 2, each stock certificate for
Warrant Shares issued upon the exercise of any Warrant and each stock
certificate issued upon the direct or indirect transfer of any such Warrant
Shares shall be stamped or otherwise imprinted with a legend in substantially
the following form:

          "THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
     APPLICABLE STATE SECURITIES LAWS, AND HAVE BEEN ISSUED PURSUANT TO AN
     EXEMPTION THEREFROM. EXCEPT AS PERMITTED UNDER APPLICABLE FEDERAL AND STATE
     SECURITIES LAWS, THE SHARES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR
     OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION UNDER THE
     SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF
     COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED."

     Notwithstanding the foregoing, the Warrantholder may require the Company to
issue a stock certificate for Warrant Shares without a legend if (i) such
Warrant Shares, as the case may be, have been registered for resale under the
Securities Act or sold pursuant to Rule 144 under the Securities Act (or a
successor rule thereto) or (ii) the Warrantholder has received an opinion of
counsel reasonably satisfactory to the Company that such registration is not
required with respect to such Warrant Shares. If either condition in the
foregoing sentence has been satisfied, the Company shall, without expense
(except for the payment of any applicable transfer tax) and as expeditiously as
possible, issue a new stock certificate not bearing such legend.

     2.3 REGISTRATION. The Warrant Shares shall be deemed to constitute
"Registrable Securities" defined in the Second Amended and Restated Shareholders
Agreement, dated as of December 15, 2006 (the "Shareholders Agreement"), among
the Company, Yingli Power Holding Company Ltd., Mr. Liansheng Miao and the
investors listed on Schedule I attached thereto. In respect of the Warrant
Shares, the Warrantholder shall be entitled to the registration rights to which
the Series B Shareholders (as defined in the Shareholder Agreement) are entitled
under the Shareholders Agreement.

     2.4 SPLIT-UP, COMBINATION AND EXCHANGE OF WARRANTS. This Warrant may be
split up, combined or exchanged for another Warrant or Warrants containing the
same terms to purchase a like aggregate number of Warrant Shares. If the
Warrantholder desires to split up, combine or exchange this Warrant, the
Warrantholder shall make such request in writing delivered to the Company and
shall surrender to the Company this Warrant and any other Warrants to be so
split-up, combined or exchanged. Upon any such surrender for a split-up,
combination or exchange, the Company shall execute and deliver to the person
entitled thereto a Warrant or Warrants, as the case may be, as so requested. The
Company shall not be required to effect any split-up, combination or exchange
which will result in the

                                      -4-

<PAGE>

issuance of a Warrant entitling the Warrantholder to purchase upon exercise a
fraction of an Ordinary Share or a fractional Warrant. The Company may require
such Warrantholder to pay a sum sufficient to cover any tax or governmental
charge that may be imposed in connection with any split-up, combination or
exchange of Warrants.

     3. RESERVATION OF SHARES

     The Company covenants and agrees that all Warrant Shares which are issuable
upon the exercise of this Warrant will, upon issuance, be validly issued, fully
paid and nonassessable and free from all taxes, liens, security interests,
charges and other encumbrances with respect to the issue thereof, other than
taxes in respect of any transfer occurring contemporaneously with such issue.
The Company further covenants and agrees that, during the Exercise Period, the
Company will at all times have authorized and reserved, and keep available free
from preemptive rights, a sufficient number of Ordinary Shares to provide for
the exercise of the rights represented by this Warrant.

     4. EXCHANGE, LOSS OR DESTRUCTION OF WARRANT.

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant and, in the case of
loss, theft or destruction, of such bond or indemnification as the Company may
reasonably require, and, in the case of such mutilation, upon surrender and
cancellation of this Warrant, the Company will execute and deliver a new Warrant
of like tenor. The term "Warrant" as used in this Agreement shall be deemed to
include any Warrants issued in substitution or exchange for this Warrant.

     5. OWNERSHIP OF WARRANT.

     The Company may deem and treat the person in whose name this Warrant is
registered as the holder and owner hereof (notwithstanding any notations of
ownership or writing hereon made by anyone other than the Company) for all
purposes and shall not be affected by any notice to the contrary.

     6. CERTAIN ADJUSTMENTS.

     6.1 The number of Warrant Shares purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment as follows:

     (a) Share Dividends, Share Splits, or Share Subdivisions. If at any time
prior to the exercise of this Warrant in full (i) the Company shall fix a record
date for the issuance of any share dividend payable in Ordinary Shares or the
Company's assets (excluding cash dividends paid or payable solely out of
retained earnings) or (ii) the number of Ordinary Shares shall have been
increased by a subdivision or split-up of Ordinary Shares, then, on the record
date fixed for the determination of holders of Ordinary Shares entitled to
receive such dividend (without payment of additional consideration for such
dividend), or immediately after the effective date of subdivision or split-up,
as the case may be, the number of Ordinary Shares to be delivered upon exercise
of this Warrant will be increased so that the Warrantholder will be entitled to
receive the number of Ordinary Shares that such Warrantholder would have owned
immediately following such action had this Warrant been exercised immediately
prior thereto, and the Exercise Price will be adjusted as provided below in
paragraph (f).

                                      -5-

<PAGE>

     (b) Combination of Stock. If at any time prior to the exercise of this
Warrant in full the number of Ordinary Shares outstanding shall have been
decreased by a combination of the outstanding Ordinary Shares, then, immediately
after the effective date of such combination, the number of Ordinary Shares to
be delivered upon exercise of this Warrant will be decreased so that the
Warrantholder thereafter will be entitled to receive the number of Ordinary
Shares that such Warrantholder would have owned immediately following such
action had this Warrant been exercised immediately prior thereto, and the
Exercise Price will be adjusted as provided below in paragraph (f).

     (c) Preservation of Purchase Rights in Certain Transactions. In case of any
reclassification, capital reorganization or other change of outstanding Ordinary
Shares (other than a subdivision or combination of the outstanding Ordinary
Shares and other than a change in the par value of the Ordinary Shares) or in
case of any consolidation or merger of the Company with or into another
corporation (other than merger with a subsidiary in which the Company is the
continuing corporation and that does not result in any reclassification, capital
reorganization or other change of outstanding Ordinary Shares of the class
issuable upon exercise of this Warrant) or in the case of any sale, lease,
transfer or conveyance to another corporation of the property and assets of the
Company as an entirety or substantially as an entirety, the Company shall, as a
condition precedent to such transaction cause such successor or purchasing
corporation, as the case may be, to execute with the Warrantholder an agreement
granting the Warrantholder the right thereafter, upon payment of the Exercise
Price in effect immediately prior to such action, to receive upon exercise of
this Warrant the kind and amount of shares and other securities and property
which the Warrantholder would have owned or have been entitled to receive after
the happening of such reclassification, change, consolidation, merger, sale or
conveyance had this Warrant been exercised immediately prior to such action. In
the event that in connection with any such reclassification, capital
reorganization, change, consolidation, merger, sale or conveyance, additional
Ordinary Shares shall be issued in exchange, conversion, substitution or
payment, in whole or in part, for, or of, a security of Company other than
Ordinary Shares, any such issue shall be treated as an issue of Ordinary Shares
covered by the provisions of Article 6. The provisions of this Section 6.1 shall
similarly apply to successive reclassifications, capital reorganizations,
consolidations, mergers, sales or conveyances.

     (d) Fractional Shares. No fractional Ordinary Shares or scrip shall be
issued to any Warrantholder in connection with the exercise of this Warrant.
Instead of any fractional Ordinary Shares that would otherwise be issuable to
such Warrantholder, the Company will pay to such Warrantholder a cash adjustment
in respect of such fractional interest in an amount equal to that fractional
interest of the fair market value of one Ordinary Share as of the date of
exercise as determined by the Board of Directors of the Company.

     (e) Carryover. Notwithstanding any other provision of this Section 6, no
adjustment shall be made to the number of Ordinary Shares to be delivered to the
Warrantholder (or to the Exercise Price) if such adjustment represents less than
1% of the number of shares to be so delivered, but any lesser adjustment shall
be carried forward and shall be made at the time and together with the next
subsequent adjustment which together with any adjustments so carried forward
shall amount to 1% or more of the number of shares to be so delivered.

                                      -6-

<PAGE>

     (f) Exercise Price Adjustment. Whenever the number of Warrant Shares
purchasable upon the exercise of the Warrant is adjusted, as herein provided,
the Exercise Price payable upon the exercise of this Warrant shall be adjusted
by multiplying such Exercise Price immediately prior to such adjustment by a
fraction, of which the numerator shall be the number of Warrant Shares
purchasable upon the exercise of the Warrant immediately prior to such
adjustment, and of which the denominator shall be the number of Warrant Shares
purchasable immediately thereafter, provided that the Exercise Price shall not
be less than the par value of the Ordinary Share.

     (g) No Duplicate Adjustments. Notwithstanding anything else to the contrary
contained herein, in no event will an adjustment be made under the provisions of
this Section 6 to the number of Warrant Shares issuable upon exercise of this
Warrant or the Exercise Price for any event if an adjustment having
substantially the same effect to the Warrantholder as any adjustment that
otherwise would be made under the provisions of this Section 6 is made by the
Company for any such event to the number of Ordinary Shares (or other
securities) issuable upon exercise of this Warrant.

     6.2 NO ADJUSTMENT FOR DIVIDENDS. Except as provided in Section 6.1, no
adjustment in respect of any dividends shall be made during the term of the
Warrant or upon the exercise of this Warrant.

     6.3 NOTICE OF ADJUSTMENT. Whenever the number of Warrant Shares or the
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail by first class, postage prepaid, to the
Warrantholder, notice of such adjustment or adjustments and a certificate of the
chief financial officer of the Company setting forth the number of Warrant
Shares and the Exercise Price of such Warrant Shares after such adjustment,
setting forth a brief statement of the facts requiring such adjustment and
setting forth the computation by which such adjustment was made.

     7. NOTICES OF CORPORATE ACTION.

     In the event of:

     (a) any taking by the Company of a record of the holders of any class of
securities for the purpose of determining the holders thereof who are entitled
to receive any dividend or other distribution, or any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, or

     (b) any capital reorganization of the Company, any reclassification or

securities or other property deliverable upon such reorganization,
reclassification, recapitalization, Change of Control, redemption or conversion
of Ordinary Shares, dissolution, liquidation or winding-up and (iii) that in the

inconsistent with the rights granted to the Warrantholder or otherwise conflicts
with the provisions hereof. The rights granted to the Warrantholder hereunder do
not in any way conflict with and are not inconsistent with the rights granted to
holders of the Company's securities under any other agreements.

     9.11 ATTORNEYS' FEES. In any action or proceeding brought to enforce any
provisions of this Warrant, or where any provision hereof is validly asserted as
a defense, the successful party shall be entitled to recover reasonable
attorneys' fees and disbursements in addition to its costs and expenses and any
other available remedy.

     9.12 DISPUTE RESOLUTION. Any controversy or claim arising out of or
relating to this Agreement, or any breach of this Agreement, shall be initiated,
maintained and finally determined by binding arbitration under the rules of
conciliation and arbitration of the International Chamber of Commerce (the
"ICC"); and the site of the arbitration, unless the parties agree otherwise,
shall be in Hong Kong. The arbitral tribunal shall be appointed within thirty
(30) days of the notice of dispute, and shall consist of three arbitrators, one
of which shall be appointed by the Warrantholder and one by the Company and the
third by the Warrantholder and the Company jointly; provided, however, that if
the Warrantholder and the Company shall be unable to select the third arbitrator
within such thirty (30)-day period, such third arbitrator shall be chosen by the
International Court of Arbitration of the ICC. Judgment upon any award rendered
may be entered in any court having jurisdiction thereof, or application may be
made to such court for a judicial acceptance of the award and an order of
enforcement, as the case may be. Any award pursuant to such proceeding shall be
granted in U.S. Dollars. The fees and costs of the arbitration shall be shared
equally by all disputing parties. The arbitrators shall award legal fees,
disbursements and other expenses to the prevailing party for such amounts as
determined by the arbitrators to be appropriate.

     9.13 NO IMPAIRMENT. The Company will not cooperate with or facilitate any
amendment of its Memorandum and Articles of Association or other constitutional
documents, or any reorganization, consolidation, merger, dissolution, issue or
sale of shares, sale of assets or any other voluntary action, so as to avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such action as may be necessary or appropriate in order
to protect the rights of the Warrantholder against impairment. Without limiting
the generality of the foregoing, the Company (a) will use its best efforts to
ensure that the par value of any shares issuable upon the exercise of this
Warrant will not be increased above the amount payable therefor upon such
exercise, and (b) will take or procure the taking of all such action as may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and non-assessable Warrant Shares upon exercise of this Warrant.
