            WHEREAS, GTS is not currently subject to the restrictions of Section
203 of the DGCL, but in furtherance of the Proposed Transaction has agreed to be

            NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Stockholders and the Company agree as follows:

            Section 1. Representations and Warranties. Each of the Stockholders
and the Company represents to the other parties, as to itself, that all
necessary corporate action to authorize the execution and delivery of this
Agreement has been taken by it, that this Agreement has been duly executed and
delivered by it and that this Agreement constitutes a valid and legally binding
obligation by it and is enforceable in accordance with its terms.

            Section 2. Certain Defined Terms. As used in this Agreement, the
terms "Affiliate," "Business Combination," "Interested Stockholder," and "Voting
Stock" have the meanings ascribed to them in Section 203(c) of the DGCL in
effect on the date hereof. For the purposes of this Agreement, the Company is
not deemed to be an Affiliate of the Stockholders. A copy of Section 203 of the
DGCL as currently in effect is attached hereto as Exhibit B.

            The term "Disinterested Director" means any member of the Board who
is neither an officer, director nor a person who controls or is under common
control with the Stockholder, or any Affiliate of the Stockholder that at the
time proposes to engage in a Business Combination with the Company.

            The term "fully diluted basis" means all outstanding Voting Stock or
other shares of capital stock of the Company taking into account any options,
warrants, convertible securities, or other rights to acquire Voting Stock.

            Section 3. Business Combination. Subject to the requirements of
Section 4 of this Agreement, each of the Stockholders agrees that it will not
engage and shall not permit any of its Affiliates to engage, in any Business
Combination with the Company without the prior approval of the Board, which
approval will be effective only if it includes the affirmative vote of a
majority of the Disinterested Directors. If no Disinterested Directors are in
office, then each of the Stockholders agrees that it will not engage and will
not permit any of its Affiliates to engage, in any Business Combination with the
Company or its Affiliates unless such Business Combination is approved in
accordance with Section 203(a)(3) of the DGCL as in effect on the date hereof.

            Section 4. Board Composition and Board Nominees. The Stockholders
and the Company agree that the Board shall consist of nine (9) members. Alfa
shall be entitled to designate not less than three (3) but no more than four (4)
directors to the Board. The Stockholders and the Company agree further that the
nomination and removal of directors to the Board shall be governed by Section 3

directors on the Board or any increase in the number of nominees designated to
the Board by Alfa, Barings or Capital, respectively) must be made in accordance
with Section 9 hereof.

            Section 5. Standstill Agreement.

            (a) Each of the Stockholders agrees that, from and after the date
hereof, unless this Agreement is earlier terminated, it will not, nor will it
permit its respective Affiliates to, directly or indirectly, in any manner
acquire, or agree to acquire, any Voting Stock of the Company, to the extent
that the acquisition of such Voting Stock would increase the ownership of such
Stockholder and its Affiliates to more than (i) the percentage of the Voting
Stock then outstanding (calculated on a fully-diluted basis) as set forth
opposite each such Stockholder's name in the first column below, or (ii) the
percentage of the Voting Stock then outstanding (calculated on a non-fully
diluted basis) set forth opposite such Stockholder's name in the second column
below.


            Alfa              43.00%            49.99%
            GTS               43.00%            49.99%

            Barings           17.20%            20.00%

voted by a Stockholder that holds Voting Stock in excess of the limitation in
Section 5 (a) above; and

                                       3
<PAGE>   4
                  (ii) In the event that that Board determines to conduct an
auction of the Company, then each of the Stockholders may participate in any
auction on the same terms as all other bidders, notwithstanding any provisions
in this Agreement to the contrary; and

                  (iii) In the event that any person other than Alfa, European
Bank of Reconstruction and Development, Capital or Barings or any of their
respective affiliates acquires, or proposes to acquire beneficial ownership of
greater than 15% of the outstanding Voting Stock of the Company.

            (c) Each of the Stockholders agrees that, from and after the date
hereof, unless this Agreement is earlier terminated, it will not, nor will it
permit its respective Affiliates, to make or in any way participate in any
"solicitation" of "proxies" (as such terms are used in the proxy rules of the
United States Securities and Exchange Commission) to vote any Voting Stock of
the Company in connection with the election of the directors of the Company
(other than proxies to vote any Voting Stock beneficially owned by such
Stockholders and/or its respective Affiliates').

            (d) Each of the Stockholders agrees that, from and after the date
hereof, unless this Agreement is earlier terminated, it will not, nor will it
permit its Affiliates to make or in any way participate in any way in any
"solicitation" of "proxies" (as such terms are used in the proxy rules of the
United States Securities and Exchange Commission) to vote any Voting Stock, with
respect to any matter, other than the election of directors of the Company
(which is governed by Section 4 hereof ) (a "Non-Election Issue"), which may be
submitted to a vote of the stockholders of the Company (other than proxies to
vote any Voting Stock beneficially owned by such Stockholders and/or its
respective Affiliates) with respect to any such Non-Election Issue.

            (e) Each of the Stockholders agrees that from and after the date
hereof, it will not amend the voting provisions of the Shareholders Agreement or
enter into any other agreement, arrangement or understanding with respect to
voting its shares of Common Stock without the prior approval of the Board, which
approval will be effective only if it includes the affirmative vote of a
majority of the Disinterested Directors.

            (f) Notwithstanding anything to the contrary contained in Section
5(a) through 5(d), nothing contained in this Agreement shall be construed to
prevent any of the Stockholders or any of their respective Affiliates from: (i)
making a tender offer for the Common Stock so long as such tender offer is made
on an any and all basis; or (ii) communicating with any other holder or holders
of the Company's outstanding securities, including, without limitation, the
expression of the opinion of the Stockholders with respect to any third-party
solicitation of proxies, provided that such Stockholder does not (A) provide to
any security holder of the Company a form of proxy or other authorization
permitting a stockholder (or its designee) to vote any equity security of the
Company on such security holder's behalf or (B) accept from any security holder
of the Company a proxy or other authorization permitting the Stockholders (or
its designee) to vote any equity security of the Company on such

                                       4
<PAGE>   5
security holder's behalf, provided that clauses (A) and (B) above shall not be
deemed to prevent the solicitation of proxies to vote Company securities
beneficially owned by such Stockholders, as contemplated by Sections 5(b) and
5(c) above.

            Section 6. Purchase Rights of the Stockholders. Until the
termination of this Agreement, the Company will give the Stockholders at least
30 days' (and, when possible at least 90 days') prior written notice of the
issuance by the Company of any Voting Stock or any other shares of capital stock
of the Company and any options, warrants, convertible securities, or other
rights to acquire Voting Stock or other capital stock of the Company or
securities exercisable or convertible for Voting Stock or other capital stock of
the Company ("New Securities") as a result of which a Stockholder's beneficial
ownership of the Company would be reduced, either immediately upon issuance of
such New Securities or upon the exercise or conversion thereof. Such notice must
set forth (a) the approximate number and type of New Securities proposed to be
issued and sold and the material terms of such New Securities, (b) the proposed
price or range of prices at which such New Securities are proposed to be sold
and the terms of payment, (c) the number of such New Securities to be offered
for sale and (d) any other material feature, term or condition relating to such
New Securities or the proposed sale thereof. Upon receipt of such notice from
the Company, each Stockholder will have the right, but not the obligation, to
elect to purchase up to its pro-rata share of such New Securities on a fully
diluted basis. Such pro-rata share, for purposes of this Section 6, for any a
Stockholder is the ratio of (x) the sum, without duplication, of the total
number of shares of Voting Stock or any other shares of capital stock of the
Company, held by such Stockholder prior to the issuance of New Securities
assuming the full exercise or conversion of any options, warrants, convertible
securities exercisable or convertible for Voting Stock or other capital stock of
the Company to (y) the sum, without duplication, of the total number of shares
of Voting Stock or any other shares of capital stock of the Company outstanding
immediately prior to the issuance of New Securities held by all stockholders of
the Company, assuming the full exercise or conversion of any options, warrants,
convertible securities exercisable or convertible for Voting Stock or other
capital stock of the Company. Each Stockholder's purchase must be on the same
terms and conditions as the balance of such issuance of New Securities;
provided, however, if the sale price at which the Company proposes to issue,
deliver or sell any New Securities is to be paid with consideration other than
cash, then the purchase price at which Alfa, Capital or Barings may acquire its
portion of such New Securities will be equal in value (as determined in good
faith by the Board) but payable entirely in cash. The closing of each
Stockholder's purchase of its portion of such New Securities will occur
simultaneously with the closing of the balance of the issuance of such New
Securities; provided, however, if as of the date of said closing all necessary
approvals of governmental authorities required in connection with the issuance
of such New Securities have not been obtained by the Company and/or a
Stockholder then (i) such Stockholder will not be required to effect purchase of
its portion of such New Securities until all necessary governmental authority
approvals are obtained and (ii) the Company may terminate such Stockholder's
right to purchase its portion of such New Securities if such Stockholder fails
to obtain any necessary approvals of governmental authority applicable only to
such Stockholder within 120 days of the closing of the balance of the issuance
of such New Securities. If at any time, the terms of a proposed issuance of New
Securities are materially changed, altered or modified from those stated in the
Company's notice to the Stockholders of the proposed issuance thereof, then such
proposed

                                       5
<PAGE>   6
issuance will be treated as a new issuance, subject to the notice obligation of
the Company set forth above and any election of a Stockholder to purchase its
portion of such New Securities prior to such change, alteration or modification
may, in the sole discretion of such Stockholder be withdrawn. Notwithstanding
any provision herein to the contrary in no event shall a Stockholder be
permitted to exercise its rights under this Section 6, to the extent such
exercise would cause it to exceed the limitations set forth in Section 5 hereof.

            Section 7. Term. This Agreement will terminate and the provisions of
this Agreement will be of no further force or effect upon the occurrence of any
of the following: (i) the mutual agreement of the parties in accordance with
Section 9 hereof, (ii) upon termination of the Share Purchase Agreement prior to
the consummation of the purchase of shares thereby, (iii) the voluntary or
involuntary filing of a petition in bankruptcy by or against the Company, an
event of insolvency affecting the Company, or the appointment of a receiver for
the Company or (iv) on the second anniversary of the date on which the Proposed
Transaction is consummated.

            Section 8. Remedies. The Stockholders, on the one hand, and the
Company, on the other, acknowledge and agree that irreparable damage would occur
in the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties are entitled to an injunction or injunctions
to prevent or cure breaches of the provisions of this Agreement and to enforce
specifically the terms and provisions hereof in any court of the United States
or any state thereof having jurisdiction, this being in addition to any other
remedy to which they may be entitled at law or equity.

            Section 9. Amendments and Termination. This Agreement may not be
amended or terminated except pursuant to a writing signed by all parties hereto.
Notwithstanding anything to the contrary contained herein, the Stockholders are
not entitled to amend the provisions hereof or terminate this Agreement unless:
(i) the holders of a majority of the Voting Stock (calculated without reference
to any Voting Stock held by the Stockholders or their respective Affiliates)
approve a proposal submitted by the Board authorizing such amendment or (ii) a
majority of the Disinterested Directors shall approve a resolution authorizing
such amendment.

            Section 10. Entire Understanding. This Agreement contains the entire
understanding of the parties with respect to the matters covered hereby.

            Section 11. Counterparts. This Agreement may be executed by the
parties hereto in counterparts and each such executed counterpart shall be an
original instrument. This Agreement will be deemed to have been executed and
delivered by the parties so long as each of the Company and the Stockholders
have duly executed and delivered a counterpart of this Agreement even if no
single counterpart has been executed by both parties.

            Section 12. Notices. All notices, consents, requests, instructions,
approvals and other communications provided for herein and all legal process in
regard hereto will be
