purposes as the holder of record of such shares as of the close of business on
such date.  As soon as practicable but no
later than seven (7) days after delivery of the exercise notice to the Company,
the Company shall issue and deliver to the person or persons entitled to
receive the same a certificate or certificates for the number of whole shares
of Option Stock issuable upon such exercise.

portion of the Option to be repurchased and the Repurchase Price.  The Repurchase Price shall be payable, at the
option of the Company, by check or by cancellation of all or a portion of any
outstanding indebtedness of Optionee to the Company, or by any combination
thereof.  The Repurchase Price shall be
paid without interest within five (5) days after delivery of the notice of
exercise of the Repurchase Right, against delivery by the Optionee of this
Agreement.

6.             Investment
Intent.

 3

Option is granted on the condition that Optionee’s purchase of Option Stock
shall be for investment purposes and not with a view to resale or distribution.

Stand-Off” Agreement.

7.1.          If requested by the Company or the
managing underwriter pursuant to any proposed public offering of the Company’s
securities, the Optionee hereby agrees that it shall not, directly or
indirectly, sell, lend, pledge, offer, transfer, make any short sale of, sell
any option or contract to purchase, contract to sell, purchase any option or
contract to sell, grant any option, right or warrant for the purchase of,
otherwise transfer or dispose of, or enter into any hedging or similar

statement for such public offering for a period specified by the Company not to
exceed ninety (90) days following the effective date of the public

managing underwriter in the public offering that are consistent with this

7.2.          In order to enforce the foregoing
covenant, the Company may impose stop transfer instructions with respect to the
Shares until the end of such period.

of Company’s Liability for Nonissuance. 
The Company agrees to use its reasonable best efforts to obtain from any
applicable regulatory agency such authority or approval as may be required in
order to issue and sell the Shares to the Optionee pursuant to this
Option.  Inability of the Company to
obtain, from any such regulatory agency, authority or approval deemed by the Company’s
counsel to be necessary for the lawful issuance and sale of the Shares
hereunder shall relieve the Company of any liability in respect of the
nonissuance or sale of such shares as to which such requisite authority or
approval shall not have been obtained.

9.             Notices.

9.1.          In Writing.  All notices, demands, requests, or other
communications permitted or required under this Agreement or applicable law

requested, postage prepaid and addressed to either Optionee or the Company at
the addresses appearing in the preamble to this Agreement, or at such other
address as either party shall have communicated to the other pursuant to this
Section.  All such communications shall
be deemed effectively delivered upon personal service or three (3) days after
deposit in the United States Mail.

10.           Miscellaneous.

10.1.        Successors and Assigns.  Except as otherwise provided herein, this
Agreement shall inure to the benefit of only the Company, Optionee and their
respective successors or assigns.

10.2.        Severability.  If any provision or provisions of this
Agreement are adjudged to be for any reason unenforceable, illegal or void, the
remainder of its provisions shall remain in full force and effect.

 4
 

10.3         Integration.  This Agreement, along with the Settlement
Agreement,  constitute the entire
understanding of the parties concerning the Option granted hereby.  Except as otherwise provided, any changes,
modifications, or variations to this Agreement or the Option are invalid unless
stated in writing and executed by the Company and Optionee.

10.4.        Governing Law.  This Agreement and the Option granted hereby
shall be governed by the laws of the State of California.

10.5.        Attorneys Fees.  If either party brings an action or seeks to
enforce or interpret any of the terms or provisions of this Agreement, the
prevailing party shall be entitled to recover its reasonable attorneys’ fees
and costs in addition to any other remedy it may be awarded.

10.6.        Counterparts.  This Agreement may be executed in
counterparts which shall constitute the whole instrument.

10.7.        Titles for Convenience; Gender and

Amendment”), dated as of January 10, 2007, is entered into by and among
Peninsula Gaming, LLC, a Delaware limited liability company (“Employer”),
Peninsula Gaming Partners, LLP (“PGP”), a Delaware limited liability
company, and Jonathan Swain (“Employee”).

WHEREAS, Employer and Employee entered into an Employment Agreement,
dated as of July 14, 2004, as amended by that certain Amendment to Employment
Agreement, dated as of February 25, 2005, that certain Second Amendment to
Employment Agreement, dated as of September 12, 2005 and that Third Amendment
to Employment Agreement, dated as of December 18, 2006 (as amended, the “Agreement”):

WHEREAS, the parties hereto desire to further amend the Agreement
subject to the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual agreements and
understandings set forth herein and for good and valuable consideration the adequacy
and receipt of which is hereby acknowledged, the parties hereto agree as
follows:

1.             Section 4(a) of the
Agreement is hereby amended by deleting the last two sentences thereof in their
entirety and replacing them with the following:

“On January 1 of each
calendar year of the Term thereafter, commencing on January 1, 2006, if
Employee shall remain employed by the Employer as of such date, Employee shall
be entitled to receive a cash bonus payable by the Employer based on Employee’s
performance during the previous calendar year, which bonus shall be consistent
with past practices and/or the bonus plan in place for similarly situated
executive officers of the Employer and, in any event, no less than $100,000 per
year.  If this Agreement is terminated

bonus at termination.”

other agreements, documents or instruments executed and delivered pursuant to
the Agreement, shall mean and be a reference to the Agreement, as amended by
this Third Amendment.

3.             Capitalized terms
used herein and not otherwise defined shall have the meanings set forth in the
Agreement.

4.             This Amendment may
be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same
instrument.

  
  
 

IN WITNESS WHEREOF, the
parties hereto have caused this instrument to be duly executed as of the date
first above written.
