the Securities Act (as defined below); and

registration rights.

        NOW, THEREFORE, in consideration of the foregoing premises and for other

received by each Holder until such time as the Company notifies the Holder that
the requirements of ASR 130 and 135 have been met. Each Holder understands that
ASR 130 and 135 relate to publication of financial results of post-closing
combined operations of the Company and STL. The Company agrees that it will

will notify the Holders promptly following such publication.

                      (i) The Merger Agreement;

                      (ii) The Company's 1997 Annual Report to Shareholders;

                                       2


<PAGE>   3
                      (v) The Company's Proxy Statement for its 1998 Annual
Meeting of Stockholders.

               (b) Holder acknowledges that [CHECK AT LEAST ONE BOX]:

               [ ] Holder is an "accredited investor" as defined in Rule 501(a)
of Regulation D as adopted by the Commission, as set forth in Appendix 1 hereto.

               [ ] William L. Eisenhart has acted as Holder's purchaser
representative (as defined in Rule 501(h) of Regulation D as adopted by the
Commission) in connection with evaluating the merits and risks of the Merger.

               (c) Holder has been advised that, as of the date hereof, Holder
may be deemed to be an "affiliate" of STL, as the term "affiliate" is used in
and for purposes of ASR 130 and 135.

               (d) Holder understands that the representations, warranties and
covenants set forth herein will be relied upon by STL, other shareholders of
STL, the Company, shareholders of the Company and their respective counsel and
accounting firms.

               (e) Holder hereby represents and warrants that Holder has not
sold, exchanged, transferred, pledged, disposed of or otherwise reduced Holder's
risk relative to any shares of STL common stock owned by Holder during the
thirty (30) day period preceding the date hereof.

               (f) Holder is acquiring the Common Shares to be issued to Holder
solely in exchange for the shares of capital stock of STL owned by Holder or
otherwise issuable to Holder by STL in connection with the transactions
contemplated by the Merger Agreement.

               (g) Holder has paid no brokerage or similar commissions in
connection with the acquisition of such Common Shares.

               (h) Holder is acquiring such Common Shares solely for Holder's
account.


                                       3


<PAGE>   4
               (i) Holder has provided such information as may reasonably have
been requested by the Company in order for the Company or its counsel to
evaluate the availability of an exemption under the Securities Act for the
issuance of Company Stock to Holder.

        4. Securities Act Matters. Each Holder acknowledges and agrees that the
Common Shares to be issued to Holder have not been (and at the time of
acquisition by Holder, will not have been) registered under the Securities Act
or under the securities laws of any state, in reliance upon certain exemptive
provisions of such statutes. Holder recognizes and acknowledges that such claims
of exemption are based, in part, upon each Holder's representations contained in
this Agreement. Holder further recognizes and acknowledges that, because the
Common Shares are unregistered under federal and state laws, they are not
presently eligible for public resale, and may be sold in the future only
pursuant to an effective registration statement under the Securities Act and any
applicable state securities laws, or pursuant to a valid exemption from such
registration requirements. Holder recognizes and acknowledges that Rule 144
promulgated under the Securities Act (which facilitates routine sales of
securities in accordance with the terms and conditions of that Rule, including a
holding period requirement) is not now available to Holder for resale of the
Common Shares, and Holder recognizes and acknowledges that, in the absence of
the availability of Rule 144, a sale pursuant to a claim of exemption from
registration under the Securities Act would require compliance with some other
exemption under the Securities Act, none of which may be available for resale of
the Common Shares by Holder. Holder recognizes and acknowledges that, except as
set forth in this Agreement, the Company is under no obligation to register the
Common Shares, either pursuant to the Securities Act or the securities laws of
any state.

        5. Restrictive Legend. Each certificate representing Common Shares
shall, except as otherwise provided in this Section 5 or in Section 6, be
stamped or otherwise imprinted with a legend substantially in the following
form:


        "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
        AND MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS IT HAS BEEN
        REGISTERED UNDER THAT ACT OR AN EXEMPTION FROM REGISTRATION IS
        AVAILABLE.

        THE HOLDER OF THIS SECURITY IS ENTITLED TO CERTAIN REGISTRATION RIGHTS
        SET FORTH IN A STOCK RESTRICTION AND REGISTRATION RIGHTS AGREEMENT DATED
        AUGUST ______, 1998, A COPY OF WHICH MAY BE OBTAINED FROM THE SECRETARY
        OF THE CORPORATION."

Such certificates shall not bear such legend if in the opinion of counsel
satisfactory to the Company the securities being sold thereby may be publicly
sold without registration under the Securities Act or if such securities have
been sold pursuant to Rule 144 or an effective registration statement.


                                       4


<PAGE>   5
        6. Notice of Proposed Transfer. Prior to any proposed transfer of any
Common Shares, Holder shall give written notice to the Company of the Holder's
intention to effect such transfer. Each such notice shall describe the manner of
the proposed transfer and, if requested by the Company, shall be accompanied by
an opinion of counsel satisfactory to the Company to the effect that the
proposed transfer may be effected without registration under the Securities Act,
whereupon Holder shall be entitled to transfer such security in accordance with
the terms of its notice; provided, however, that no prior notice or opinion of
counsel shall be required if the sale is made in compliance with Rule 144 or if
such transfer is to one or more partners of the transferor (in the case of a
transferor that is a partnership). Each certificate for Common Shares
transferred as above provided shall bear the legend set forth in Section 5,
except that such certificate shall not bear such legend if (i) such transfer is
in accordance with the provisions of Rule 144 (or any other rule permitting
public sale without registration under the Securities Act) or (ii) the opinion
of counsel referred to above is to the further effect that the transferee and
any subsequent transferee (other than an affiliate of the Company) would be
entitled to transfer such securities in a public sale without registration under
the Securities Act. The restrictions provided for in this Section 6 shall not
apply to securities which are not required to bear the legend prescribed by
Section 5 in accordance with the provisions of that Section.

        7. Registration Procedures. On or before the Shelf Filing Date, the
Company shall file a "shelf" registration statement pursuant to Rule 415 under
the Securities Act with respect to the Common Shares. In its efforts to effect
the registration of Company Shares the Company will:

           (a) prepare and file with the Commission a registration statement
with respect to such securities on or before the Shelf Filing Date and use its
reasonable efforts to cause such registration statement to remain effective
until the earlier of the sale of all Restricted Stock covered thereby or the
first anniversary of the Closing Date; provided, however, that the Company may
suspend sales at any time under the registration statement immediately upon
notice to each Holder at the last known address of each Holder, for a period or
periods of time not to exceed in the aggregate ninety (90) days, if there then
exists material, non-public information relating to the Company which, in the
reasonable opinion of the Company, would not be appropriate for disclosure
during that time; provided further, that if the Company suspends such sales, it
will keep the registration statement effective for such additional time as sales
were suspended;

           (b) prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
the period specified in paragraph (a) above;

           (c) furnish to each seller of Restricted Stock such number of
copies of the registration statement and each such amendment and supplement
thereto and the prospectus included therein (including each preliminary
prospectus) as such persons reasonably may request in order to facilitate the
public sale or other disposition of the Restricted Stock covered by such
registration statement;


                                       5


<PAGE>   6
          (d) use reasonable efforts to register or qualify the Restricted
Stock covered by such registration statement under the securities or "blue sky"
laws of such jurisdictions as the sellers of Restricted Stock reasonably shall
request, provided, however, that the Company shall not for any such purpose be
required to qualify generally to transact business as a foreign corporation in
any jurisdiction where it is not so qualified or to consent to general service
of process in any such jurisdiction;

          (e) use its reasonable best efforts to have the Restricted Stock
covered by such registration statement subject to quotation on the NASDAQ
National Market System; and

          (f) notify each seller of Restricted Stock under such
registration statement (at any time when a prospectus relating thereto is
required to be delivered under the Securities Act), of the happening of any
event of which the Company has knowledge as a result of which the prospectus
contained in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing, and promptly prepare and furnish to
such seller a reasonable number of copies of a prospectus supplemented or
amended so that, as thereafter delivered to the purchasers of such Restricted
Stock, such prospectus shall not include an untrue statement of material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein not misleading in light of the circumstances then
existing

        In connection with the registration hereunder, the sellers of Restricted
Stock will furnish to the Company in writing such information requested by the
Company with respect to themselves and the proposed distribution by them as
shall be necessary in order to assure compliance with federal and applicable
state securities laws.

        If the registration pursuant to this Section 7 involves an underwritten
public offering, the Company and each seller who wishes to participate in such
underwriting agree to enter into a written agreement with the managing
underwriter in such form and containing such provisions as are customary in the
securities business for such an arrangement between such underwriter and
companies of the Company's size and investment status.

        8. Expenses. All expenses incurred by the Company in complying with
Section 7, including, without limitation, all registration and filing fees,
printing expenses, fees and disbursements of counsel and independent public
accountants for the Company, fees and expenses incurred in connection with
complying with state securities or "blue sky" laws, fees of the National
Association of Securities Dealers, Inc., transfer taxes, fees of transfer agents
and registrars, and costs of issuance, but excluding any Selling Expenses, are
called "Registration Expenses." All underwriting discounts (if any) and selling
commissions applicable to the sale of Restricted Stock are called "Selling
Expenses."


                                       6


<PAGE>   7
          The Company will pay all Registration Expenses in connection with a
registration statement under Section 7; provided, however, that all such
expenses shall be borne by the participating sellers in proportion to the number
of shares covered by such registration statement if such registration statement
is withdrawn, delayed or abandoned for any reason by the sellers. All Selling
Expenses in connection with any registration statement under Section 7 shall be
borne by the participating sellers in proportion to the number of shares sold by
each.

        9. Indemnification and Contribution.

          (a) In connection with the registration of the Restricted Stock
under the Securities Act pursuant to Section 7, the Company will indemnify and
hold harmless each seller of such Restricted Stock thereunder, its officers and
directors, each underwriter of such Restricted Stock thereunder and each other
person, if any, who controls such seller or underwriter within the meaning of
the Securities Act, against any losses, claims, damages or liabilities, joint or
several, to which such seller, officer, director, underwriter or controlling
person may become subject under the Securities Act, Exchange Act, state
securities laws or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of material fact contained in
the registration statement under which such Restricted Stock was registered
under the Securities Act pursuant to Section 7, any preliminary prospectus or
final prospectus contained therein, or any amendment or supplement thereto, (ii)
the omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading or (iii) any
violation by the Company or its agents of any rule or regulation promulgated
under the Securities Act, Exchange Act or state securities laws applicable to
the Company or its agents and relating to action or inaction required of the
Company in connection with such registration, and the Company will reimburse
each such seller, each such officer and director, each underwriter and each such
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission so made in conformity with information furnished
in writing to the Company by any such seller, any such underwriter or any such
controlling person, specifically for use in the registration statement.

          (b) In connection with the registration of the Restricted Stock
under the Securities Act pursuant to Section 7, each seller of such Restricted
Stock thereunder, severally and not jointly, will indemnify and hold harmless
the Company, each person, if any, who controls the Company within the meaning of
the Securities Act, each officer of the Company who signs the registration
statement, each director of the Company, each underwriter and each person who
controls any underwriter within the meaning of the Securities Act, against all
losses, claims, damages or liabilities, joint or several, to which the Company
or such officer, director, underwriter or controlling person may become subject
under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) the failure of 


                                       7


<PAGE>   8
such seller to comply with the provisions of Section 12 herein or (ii) any
untrue statement or alleged untrue statement of any material fact contained in
the registration statement, any preliminary prospectus or final prospectus
contained therein, or any amendment or supplement thereto, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company and each such officer, director,
underwriter and-controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that such seller will be
liable hereunder in any such case if and only to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in reliance upon
and in conformity with information pertaining to such seller, furnished to the
Company in writing by such seller, specifically for use in the registration
statement; and provided, further, that in no event shall any indemnity under
this subsection 9(b) exceed the gross proceeds from the offering received by
such seller(s).

        (c) Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 9 and shall only relieve
it from any liability which it may have to such indemnified party under this
Section 9 if and to the extent the indemnifying party is prejudiced by such
omission. In case any such action shall be brought against any indemnified party
and it shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof and the approval by the indemnified party of the counsel chosen
by the indemnifying party, the indemnifying party shall not be liable to such
indemnified party under this Section 9 for any legal expenses subsequently
incurred by such indemnified party in connection with the defense thereof other
than reasonable costs of investigation and of liaison with counsel so selected;
provided, however, that, if the defendants in any such action include both the
indemnified party and the indemnifying party and if the interests of the
indemnified party reasonably may be deemed to conflict with the interests of the
indemnifying party, the indemnified party shall have the right to select a
separate counsel and to assume such legal defenses and otherwise to participate
in the defense of such action, with the expenses and fees of such separate
counsel and other expenses related to such participation to be reimbursed by the
indemnifying party as incurred.

        (d) In order to provide for just and equitable contribution to
joint liability in any case in which either (i) any Holder of Restricted Stock
exercising rights under this Agreement, or any controlling person of any such
Holder, makes a claim for indemnification pursuant to this Section 9, but it is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time 


                                       8


<PAGE>   9
to appeal or the denial of the last right of appeal) that such indemnification
may not be enforced in such case notwithstanding the fact that this Section 9
provides for indemnification in such case, or (ii) contribution under the
Securities Act may be required on the part of any such selling Holder or any
such controlling person in circumstances for which indemnification is provided
under this Section 9; then, and in each such case, the Company and such Holder
will contribute to the aggregate losses, claims, damages or liabilities to which
they may be subject (after contribution from others) in proportion to the
relative fault of the Company, on the one hand, and each Holder, severally, on
the other hand; provided, however, that, in any such case, no person or entity
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) will be entitled to contribution from any person or entity
who was not guilty of such fraudulent misrepresentation and; provided, further,
that in no event shall any indemnity under this subsection 9 (d) exceed the
gross proceeds from the offering received by such Holder.

          (e) The indemnities provided in this Section 9 shall survive the
transfer of any Restricted Stock by any Holder.

        10. Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation thereunder that may at any time
permit a Holder to sell securities of the Company to the public without
registration, the Company agrees to:

          (a) make and keep public information available, as those terms
are understood and defined in Rule 144;

          (b) maintain registration of its Common Stock under Section 12 of
the Exchange Act;

          (c) file in a timely manner all reports and other documents
required of the Company under the Securities Act and the Exchange Act; and

          (d) furnish to any Holder, so long as the Holder owns any
Restricted Securities, forthwith upon request: (i) a written statement by the
Company that it has complied with the reporting requirements of Rule 144, (ii) a
copy of the most recent annual or quarterly report of the Company and such other
reports and documents so filed by the Company; and (iii) such other information
as may be reasonably requested in availing any Holder of any rule or regulation
under the Securities Act which permits the selling of any such securities
without registration or pursuant to such form.

        11. Changes in Common Stock. If, and as often as, there is any change in
the Common Stock by way of a stock split, stock dividend, combination or
reclassification, or through a merger, consolidation, reorganization or
recapitalization, or by any other means, appropriate adjustment shall be made in
the provisions hereof so that the rights and privileges granted hereby shall
continue with respect to the Common Stock as so changed.

<PAGE>   10
        12. Sellers' Conduct. With respect to any sale of Common Shares pursuant
to Section 7, each Holder understands and agrees as follows:

           (a) Holder will carefully review the information concerning
Holder contained in the registration statement (if any) and will promptly notify
the Company if such information is not complete and accurate in all respects,
including having properly disclosed any position, office or other material
relationship within the past three years with the Company or its affiliates;

           (b) Holder agrees to sell Holder's Common Shares only in the
manner set forth in the registration statement;

           (c) Holder agrees to comply with the anti-manipulation rules
under the Exchange Act in connection with purchases and sales of securities of
the Company during the time the registration statement remains effective;

           (d) Holder agrees to only sell shares in a jurisdiction after
counsel for the Company has advised that such sale is permissible under the
applicable state securities or "Blue Sky" laws;

           (e) Holder agrees to comply with the prospectus delivery
requirements of the Exchange Act;

           (f) Holder agrees to promptly notify the Company of any and all
planned sales and completed sales of shares;

           (g) Holder agrees to suspend sales during the periods when sales
are to be suspended pursuant to Section 7(a) herein; and

            (h) Holder agrees not to take any action that could adversely
affect the ability of the Company to account for the business combination to be
effected by the Merger as a pooling of interests.

        13. Miscellaneous.

            (a) All covenants and agreements contained in this Agreement by
or on behalf of any of the parties hereto shall bind and inure to the benefit of
the respective successors and assigns of the parties hereto (including without
limitation transferees of any Restricted Stock, provided, that such transferee
executes a counterpart signature page to this Agreement), whether so expressed
or not.

            (b) All notices, requests, consents and other communications
hereunder shall be in writing and shall be mailed by certified or registered
mail, return receipt requested, postage prepaid, or telexed, in the case of
non-U.S. residents, addressed as follows:
