"Investor"), Yingli Green Energy Holding Company Limited, an exempted company
with limited liability incorporated and existing under the laws of the Cayman

Agreement dated as of September 20, 2006, by and among the Existing Parties (the

                                   WITNESSETH:

     WHEREAS, the parties have entered into the Agreements; and

     WHEREAS, pursuant to and in accordance with Section 10.06 of the Purchase
Agreement and Section 21.6 of the Shareholders Agreement, the parties wish to
amend the Agreements as set forth in this Amendment;

     NOW, THEREFORE, in consideration of the rights and obligations contained
herein, and for other good and valuable consideration, the adequacy of which is
hereby acknowledged, the parties agree as follows:

     Section 1. Employee Stock Option Plan. The Existing Parties agree that the
Primary ESOP Percentage (as defined in the Shareholders Agreement) shall be up
to five percent (5%) of all Ordinary Shares Equivalent (as defined in the
Shareholders Agreement) immediately after the Closing, excluding the Warrant
(namely, up to 3,394,054 Ordinary Shares), up to four percent (4%) of which
shall be in the form of restricted shares (namely, up to 2,715,243 Ordinary
Shares) and up to one percent (1%) of which shall be in the form of stock
options (namely, up to 678,811 Ordinary Shares). The Existing Parties agree that
such employee stock option plan, whether in the form of restricted shares or
stock options, shall be established in a form to the reasonable satisfaction of
the Investor. The Existing Parties further agree that the Secondary ESOP
Percentage (as defined in the Shareholders Agreement) shall be zero.

     Section 2. Warrant. The Company agrees to grant a warrant to TB Management
at Closing substantially in the form of Annex A hereto (the "Warrant").

     Section 3. Exhibit A to the Purchase Agreement. The following shall be
added to Exhibit A of the Purchase Agreement:

<PAGE>

     "The Warrant, dated as of the Closing Date, granted by the Company at
Closing substantially in the form of Annex A to the Amendment Agreement, dated
as of September 27, 2006, among the parties hereto."

     Section 4. Registration Rights of the Shareholders Agreement.

     (a) TB Management agrees to adhere to and be bound by Sections 7 through
18, 21.2, 21.6, 21.8 and 21.9 of the Shareholders Agreement thereunder as if it
were a "Holder" or "Investor" (as the case may be) to the Shareholders
Agreement.

     (b) The Existing Parties agree that TB Management shall be entitled to the
benefit of all rights given in Sections 7 through 18, 21.2, 21.6, 21.8 and 21.9
of the Shareholders Agreement thereunder as if TB Management were a "Holder" or
"Investor" (as the case may be) to the Shareholders Agreement.

     (c) The Existing Parties agree that the definition of "Registrable
Securities" in the Shareholders Agreement shall be replaced in its entirety with
the following:

     "REGISTRABLE SECURITIES" means (a) the Ordinary Shares issued or issuable
upon conversion or exercise of any of the Series A Preferred Shares (b) the
Ordinary Shares issued or issuable upon the exercise of the Warrant, and (c)
Ordinary Shares issued or issuable pursuant to stock splits, stock dividends and
similar distributions to the Investor, or in exchange for or in replacement of
the Ordinary Shares referred to clause (a) or (b) above, excluding in all cases,
however, any Registrable Securities sold by a Person in a transaction in which
its rights under Sections 7 or 8 hereof are not assigned or any shares for which
registration rights have terminated pursuant to Section 10."

     Section 5. No Assignment; Binding Effect. Neither this Amendment nor any
right, interest or obligation hereunder may be assigned by any party hereto
without the prior written consent of the other party hereto and any attempt to
do so shall be void, except that the Investor may assign any or all of its
rights, interests and obligations hereunder to an Affiliate, provided that any
such Affiliate agrees in writing to be bound by all of the terms, conditions and
provisions contained herein, but no such assignment shall relieve the Investor
of its obligations hereunder. Subject to the preceding sentence, this Amendment
is binding upon, inures to the benefit of and is enforceable by the parties
hereto and their respective successors and permitted assigns.

     Section 6. No Third Party Beneficiary. The terms and provisions of this
Amendment are intended solely for the benefit of each party hereto and their
respective successors or permitted assigns, and it is not the intention of the
parties to confer third party beneficiary rights upon any other Person.

     Section 7. Entire Agreement. This Amendment constitutes the entire
agreement of the parties hereto with respect to the subject matter hereof and
supersedes all prior agreements and undertakings, both written and oral, among
the parties with respect to the subject matter hereof. Except as amended by this
Amendment, the Agreements shall continue in full force and effect.

     Section 8. Severability. If any term or other provision of this Amendment
is invalid, illegal or incapable of being enforced by any Law or public policy,
all other terms and provisions of this Amendment shall nevertheless remain in
full force and effect so long as the economic or legal substance of the
transactions contemplated by this Amendment is

                                       2

<PAGE>

not affected in any manner materially adverse to any party. Upon such
determination that any term or other provision is invalid, illegal or incapable
of being enforced, the parties hereto shall negotiate in good faith to modify
this Amendment so as to effect the original intent of the parties as closely as
possible in an acceptable manner in order that the transactions contemplated by
this Amendment are consummated as originally contemplated to the greatest extent
possible.

     Section 9. Counterparts. This Amendment may be executed and delivered
(including by facsimile transmission) in one or more counterparts, and by the
different parties hereto in separate counterparts, each of which when executed
shall be deemed to be an original but all of which taken together shall
constitute one and the same agreement.

     Section 10. Governing Law. This Amendment shall be governed by and
construed in accordance with the laws of the State of New York applicable to a
contract executed and performed in such jurisdiction, without giving effect to
the conflicts of laws principles thereof.

     Section 11. Dispute Resolution. Any dispute arising from or in connection
with this Amendment shall be resolved in accordance with Section 21.2 of the
Shareholders Agreement.

                                       3

IN WITNESS WHEREOF, this Amendment has been duly executed and delivered by or on
behalf of each party hereto as of the date first above written.

     THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT HAVE
NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED
(THE "SECURITIES ACT"), OR APPLICABLE STATE SECURITIES LAWS AND HAVE BEEN ISSUED

                   YINGLI GREEN ENERGY HOLDING COMPANY LIMITED

                        ORDINARY SHARES PURCHASE WARRANT

                    *****************************************

     This certifies that, for good and valuable consideration, Yingli Green
Energy Holding Company Limited, a Cayman Islands corporation (the "Company"),
grants to TB Management Ltd., a business company incorporated under the laws of
the British Virgin Islands (the "TB Management"), the right to subscribe for and

nonassessable shares (the "Warrant Shares") of the Company's Ordinary Shares,
$0.01 par value (the "Ordinary Shares") specified in Section 1.1 hereof, at the
purchase price per share (the "Exercise Price") determined as set forth in
Section 1.3 hereof, as may be adjusted in accordance with the terms hereof,
exercisable at any time and from time to time during the Exercise Period, as
defined in Section 1.6 hereof, all subject to the terms, conditions and
adjustments herein set forth. See Section 8 for definitions of certain terms
used herein.

<PAGE>

     1. WARRANT TERMS GENERALLY.

     1.1 NUMBER OF WARRANT SHARES.

     Subject to Section 1.6 below, this Warrant shall enable the Warrantholder
to purchase six hundred seventy-eight thousand eight hundred and eleven
(678,811) Ordinary Shares, as such number may be adjusted pursuant to the terms
hereof.

     1.2 CASH EXERCISE OF WARRANT.

     Subject to Section 1.6, this Warrant may be exercised by the Warrantholder
by (i) the surrender of this Warrant to the Company, with a duly executed
Exercise Form specifying the number of Warrant Shares to be purchased, during
normal business hours on any Business Day during the Exercise Period and (ii)
the delivery of payment to the Company, for the account of the Company, (A) by
wire transfer of immediately available funds to a bank account specified by the
Company, of the Exercise Price for the number of Warrant Shares specified in the
Exercise Form in United States Dollars, (B) by forgiveness or the offsetting of
an amount of accounts receivable from the Company to the Warrantholder equal to
the Exercise Price for the number of Warrant Shares specified in the Exercise
Form in United States Dollars or (C) by any combination of the foregoing.
Subject to Section 1.6, the Company agrees that such Warrant Shares shall be
deemed to be issued to the Warrantholder as the record holder of such Warrant
Shares as of the close of business on the date on which this Warrant shall have
been surrendered and payment made for the Warrant Shares as aforesaid. Subject
to Section 1.6, a stock certificate or certificates for the Warrant Shares
specified in the Exercise Form shall be delivered to the Warrantholder as
promptly as practicable, and in any event within 10 days thereafter. If this
Warrant shall have been exercised only in part, the Company shall, at the time
of delivery of the stock certificate or certificates, deliver to the
Warrantholder a new Warrant evidencing the rights to purchase the remaining
Warrant Shares, which new Warrant shall in all other respects be identical with
this Warrant. No adjustments shall be made on Warrant Shares issuable on the
exercise of this Warrant for any cash dividends paid or payable to holders of
record of Ordinary Shares prior to the date as of which the Warrantholder shall
be deemed to be the record holder of such Warrant Shares.

     1.3 EXERCISE PRICE.

     The Exercise Price shall be $2.1 per Warrant Share, as such price may be
adjusted from time to time pursuant to Section 6 hereof.

     1.4 PAYMENT OF TAXES. The issuance of certificates for Warrant Shares shall
be made without charge to the Warrantholder for any stock transfer or other
issuance tax in respect thereto.

     1.5 INFORMATION. Upon receipt of a written request from a Warrantholder,
the Company agrees to deliver promptly to such Warrantholder a copy of its
current financial statements and to provide such other information concerning
the Company as such Warrantholder may reasonably request in order to assist the
Warrantholder in evaluating the merits and risks of exercising the Warrant and
to make an informed investment decision in connection with such exercise.

                                      -2-

<PAGE>

     1.6 EXERCISE PERIOD. This Warrant shall be exercisable, in whole or in
part, at any time and from time to time prior to the closing of the Company's
first firm commitment, underwritten public offering of Ordinary Shares or shares
representing Ordinary Shares in connection with which Ordinary Shares or shares
representing Ordinary Shares are listed and become publicly traded on an
internationally recognized securities exchange or the NASDAQ National Market
(such period, the "Exercise Period").

     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 transferrable 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

                                      -3-

<PAGE>

     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 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 Shareholders Agreement, as amended by
the Amendment Agreement, dated as of the same date hereof (the "Shareholders
Agreement"), among Inspiration Partners Limited, the Company, Yingli Power
Holding Company Ltd., Mr. Liansheng Miao and TB Management Ltd. The
Warrantholder shall be entitled to all registration rights contained in the
Shareholders Agreement in respect of the Warrant Shares.

     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, he or it
shall make such request in writing delivered to the Company and shall surrender
to the Company this Warrant and any other Warrants to

                                      -4-

<PAGE>

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 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

                                      -5-

<PAGE>

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).

     (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 he 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

with any adjustments so carried forward shall amount to 1% or more of the number
of shares to be so delivered.

     (f) Exercise Price Adjustment. Whenever the number of Warrant Shares
purchasable upon the exercise of the Warrant is adjusted, as herein provided,

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.

     (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.

the Company. Upon issuance, the Warrant Shares will be duly authorized, validly
issued, fully paid and non-assessable, and free of any liens or encumbrances

sufficient for such purposes.

or regulation applicable to the Company. The execution, delivery and performance
of and compliance with this Warrant pursuant to the terms hereof, will not

such provision, or result in the creation of any mortgage, pledge, lien,
encumbrance or charge upon any of the properties or assets of the Company
pursuant to any such provision.
