<PAGE>

          NOW, THEREFORE, in consideration of the premises, the mutual promises
made herein and other good and valuable consideration, the receipt of which is
hereby acknowledged, the parties hereto do hereby agree as follows:

          Section 1. Amendment; Meanings of Certain Terms. This Agreement
constitutes an amendment to the Purchase Agreement and to the Shareholders
Agreement. From and after the Closing, (i) the Amethyst II Stock distributed to
Fund VIII and Fund VII (or to another member of First Reserve Group) pursuant to
the Master Agreement constitutes the "Exchangeable Stock" under the Purchase
Agreement and the Shareholders Agreement and shall be exchangeable for an
aggregate of 527,652 shares of Common Stock as set forth in the Purchase
Agreement and this Agreement, (ii) all references to "Amethyst" in the
definition of "Exchangeable Stock" in Section 1.1 of the Purchase Agreement and
in Section 5.10 of the Purchase Agreement shall be to Amethyst II, (iii) all
references to the "Amethyst Agreement" in the Purchase Agreement and the
Shareholders Agreement shall be to the Put and Exchange Agreement dated
September 14, 1999 between the Company and Fund VIII, as amended by this
Agreement, and (iv) for purposes of Section 5.11 of the Purchase Agreement, the
"Exchangeable Stock Purchase Price" shall be calculated as if First Reserve had
initially invested $6,298,851 on the Closing Date. Capitalized terms used herein
that are not otherwise defined shall have the respective meanings given them in
the Purchase Agreement.

          Section 2. Exchange of Amethyst Common Stock. At the Closing, (i) Fund
VIII shall surrender to the Company the 1,100 shares of Amethyst Common Stock
held of record by Fund VIII, (ii) Fund VII shall surrender to the Company the
150 shares of Amethyst Common Stock held of record by Fund VII, (iii) the
corresponding right to exchange such shares of Amethyst Common Stock for Common
Stock shall be cancelled, and (iv) the Company shall issue to Fund VIII and Fund
VII 457,132 shares and 62,336 shares of Common Stock, respectively. The 1,250
shares of Amethyst Common Stock so surrendered by First Reserve represent all
the capital stock of Amethyst beneficially owned by any member of the First
Reserve Group. Such surrender shall be (i) in cancellation of the exchange
rights of First Reserve with respect to the Amethyst Common Stock set forth in
Section 5.10 of the Purchase Agreement, as adjusted to take into account the
issuance of the Amethyst II Stock, and (ii) otherwise effected in accordance
with paragraphs (i) through (iv) of Section 5.10.

          Section 3. Representations and Warranties of First Reserve. First
Reserve hereby represents and warrants to the Company as follows:

                (a) Valid Title. Each of Fund VIII and Fund VII has valid title
          to the shares of Amethyst Common Stock to be exchanged by such fund
          pursuant to Section 2 hereof, free and clear of any security interest,
          mortgage, pledge, lien, charge, claim, equity or encumbrance of any
          kind; and upon delivery of such shares of Amethyst Common Stock in
          exchange for the shares of Common Stock pursuant to Section 2 hereof,
          assuming the Company has no notice of any adverse claim, the Company
          will receive valid title to such shares of Amethyst Common Stock, free
          and clear of any security interest, mortgage, pledge, lien, charge,
          claim, equity or encumbrance of any kind.

                (b) Securities Laws. Each of Fund VIII and Fund VII is an
          "accredited investor" as such term is defined in Rule 501 under the
          Securities Act. Each of Fund VIII
<PAGE>

          and Fund VII (i) has such knowledge and experience in financial and
          business matters as enables it to evaluate the merits and risks of an
          investment in the shares of Common Stock issuable upon exchange of the
          Amethyst Common Stock and the Amethyst II Stock pursuant to the
          Purchase Agreement and this Agreement (the "Company Shares") and (ii)
          is acquiring such Company Shares for its own account and not with the
          view to resale or redistribution thereof in violation of the
          Securities Act; provided, however, that each of Fund VIII and Fund VII
          shall at all times retain full power and authority over the transfer
          of its properties and assets. Each of Fund VIII and Fund VII
          acknowledges that it may not transfer the Company Shares except
          pursuant to an effective registration statement under the Securities
          Act or pursuant to an exemption from the registration requirements of
          the Securities Act, and that a legend to such effect shall be included
          on any certificate representing the Company Shares.

          Section 4. Counterparts; Facsimile. This Agreement may be executed in
