                  Re:  Millstream II Acquisition Corporation
                       -------------------------------------

Gentlemen:

         This letter will confirm the agreement of the undersigned to purchase
warrants ("Warrants") of Millstream II Acquisition Corporation ("Company")
included in the units ("Units") being sold in the Company's initial public
offering ("IPO") upon the terms and conditions set forth herein. Each Unit is
comprised of one share of Common Stock and two Warrants. The shares of Common
Stock and Warrants will not be separately tradeable until 90 days after the
effective date of the Company's IPO unless EarlyBirdCapital, Inc. ("EBC")
informs the Company of its decision to allow earlier separate trading.

         The undersigned agrees that this letter agreement constitutes an
irrevocable order for EBC to purchase for the undersigned's account within the
forty-trading day period commencing on the date separate trading of the Warrants
commences ("Separation Date") up to 1,000,000 Warrants at market prices not to
exceed $0.70 per Warrant ("Maximum Warrant Purchase"). EBC (or such other broker
dealer(s) as EBC may assign the order to) agrees to fill such order in such
amounts and at such times as it may determine, in its sole discretion, during
the forty-trading day period commencing on the Separation Date. EBC further
agrees that it will not charge the undersigned any fees and/or commissions with
respect to such purchase obligation.

         The undersigned may notify EBC that all or part of the Maximum Warrant
Purchase will be made by an affiliate of the undersigned (or another person or
entity introduced to EBC by the undersigned (a "Designee")) who (or which) has
an account at EBC and, in such event, EBC will make such purchase on behalf of
said affiliate or Designee; provided, however, that the undersigned hereby
agrees to make payment of the purchase price of such purchase in the event that
the affiliate or Designee fails to make such payment.

         The undersigned agrees that neither he nor any affiliate or Designee
shall sell or transfer the Warrants until after the consummation of a merger,
capital stock exchange, asset acquisition or other similar business combination
with an operating business and acknowledges that, at the option of EBC, the
certificates for such Warrants shall contain a legend indicating such
restriction on transferability.

                                               Very truly yours,

                                               /s/ Arthur Spector

                               AMENDMENT NO. 1 TO
             TALX CORPORATION OUTSIDE DIRECTORS' STOCK OPTION PLAN

     On May 15, 2001, the Compensation Committee of the Board of Directors
reviewed and approved a special stock option award to Outside Directors of 1,000
shares effective May 1, 2001 at the closing price of the stock on that date and
an adjustment to the annual award to 2,500 shares. The Board of Directors
approved all recommendations of the Compensation Committee on May 15, 2001.<PAGE>
                                                                          Ex 4.3

            SECOND AMENDMENT TO TALX CORPORATION OUTSIDE DIRECTORS'
                               STOCK OPTION PLAN

     WHEREAS, TALX Corporation ("Company") adopted the TALX Corporation Outside
Directors' Stock Option Plan ("Plan"); and

     WHEREAS, the Company retained the right to amend the Plan pursuant to
Section VII thereof; and

     WHEREAS, the Company desires to amend the Plan to permit the award of
restricted stock to outside directors of the Company;

     NOW, THEREFORE, effective as of July 13, 2004, the Plan is amended as
follows:

     1. Section 2 G is revised to read as follows:

          "Participant" means an Outside Director who is granted a stock option
     or restricted stock.

     2. The following sentence is added at the end of Section III:

          In addition to the foregoing, there shall also be available 50,000
     shares of the Company's Common Stock for the grant of restricted stock. Any
     shares of restricted stock which are forfeited shall again be available for
     the grant of restricted stock.

     3. Section IV is amended to read as follows:

          Stock options and restricted stock may be granted under the Plan only
     to Outside Directors.

     4. Sections VI through X are renumbered Sections VII through XI,
respectively.

     5. A new Section VI is added to read as follows:

          SECTION VI.  RESTRICTED STOCK

             A. Grant of Restricted Stock.  Upon the recommendation of the
        Compensation Committee of the Board of Directors, the Board of Directors
        may award Outside Directors a total of not more than 12,000 shares of
        restricted stock per year.

             B. Vesting of Restricted Stock.  A Participant who is awarded
        shares of restricted stock shall become vested in such stock in an
        amount equal to 1/3 the number of shares subject to such award for each
        year of service as an Outside Director following the award of such
        restricted stock with 100% vesting after 3 years of such service.
        Notwithstanding the foregoing, in the event of a Change in Control, or a
        Participant's termination of service as an Outside Director on account
        of death or Disability, the Participant (or the Participant's
        beneficiary if the Participant has died) shall become 100% vested in
        such shares of restricted stock.

             C. Termination of Service.  If a Participant who has been awarded
        restricted stock terminates service as an Outside Director for reasons
        other than death or Disability, he or she shall forfeit all shares of
        restricted stock not then vested.

     6. The following is added at the end of Section XI:

          The Second Amendment to the Plan was adopted on July 13, 2004 and
     shall become effective upon approval of the shareholders within one year
     after such adoption. If such approval is not given, the Second Amendment
     shall be void and of no further force or effect.

     IN WITNESS WHEREOF, the foregoing Second Amendment was adopted on July 13,
2004.
