                                 AMENDMENT NO. 1
                                       TO
                         EXECUTIVE EMPLOYMENT AGREEMENT

THIS AMENDMENT NO. 1 TO EXECUTIVE EMPLOYMENT AGREEMENT (this "Agreement") is
made and entered into as of the 2nd day of November 2005 (the "Effective Date")
by and between JOSEPH P. HARPER, SR. ("Mr. Harper;") STERLING CONSTRUCTION
COMPANY, INC. ("Sterling") and STERLING GENERAL, INC. ("SGI") each with a place
of business in Harris County, Texas; and STERLING HOUSTON HOLDINGS, INC. ("SHH")
with its statutory corporate office located in Wilmington, Delaware.

                                   BACKGROUND

Mr. Harper, Sterling and SHH are the parties to that certain Executive
Employment Agreement dated as of July 18, 2004 (the "Employment Agreement.")
Sterling, SHH and Mr. Harper, noting that Mr. Harper is a director, officer and
employee of SGI, now wish to amend the Employment Agreement because each
believes that it is in the best interests of Sterling and its affiliates that
Mr. Harper cease to be a director, officer and employee of SHH.

THEREFORE, in consideration of the foregoing recitals and for other good and
valuable consideration, the parties agree as follows:

1.   Sterling General, Inc. is hereby substituted for Sterling Houston Holdings,
     Inc. as a party to the Employment Agreement; the definition of "Companies"
     in the preface to the Employment Agreement is amended to mean Sterling and
     SGI; and SHH as of the date hereof ceases to be a party to the Employment
     Agreement.

2.   Each reference in the Employment Agreement to "Sterling Houston Holdings,
     Inc." is hereby replaced by a reference to "Sterling General, Inc.", and
     each reference to "SHH" is hereby replaced by a reference to "SGI," except
     as follows:

     (a)  In Section 1 ("Prior Agreements") the reference to "SHH" is amended to
          read "Sterling Houston Holdings, Inc. ("SHH")".

     (b)  In subsection (i) of Section 5(b) ("Incentive Compensation") the
          reference in the third line to "SHH" is amended to read "Texas
          Sterling Construction, L.P."

     (c)  In subsection (f) of Section 6 ("Termination") no change shall be made
          to the reference to SHH.

     (d)  In Schedule A ("Definition of EBITDA") the phrase "SHH and its
          consolidated subsidiaries for a given fiscal year" is amended to read
          "Texas Sterling Construction, L.P. for a given fiscal year".

3.   By the execution hereof, Mr. Harper waives any and all rights that he may
     have under the Employment Agreement arising out of the fact that he has
     ceased to be a director, officer and employee of SHH.

4.   In all other respects, the Employment Agreement shall remain as originally
     written.


EXECUTED effective as of the Effective Date.

STERLING CONSTRUCTION COMPANY, INC.
