         By-laws, in each case as amended to the date hereof, of the Company or
         any of its subsidiaries or any statute or any order, rule or regulation

         and clear of all liens, encumbrances, equities, security interests,
         claims and other restrictions of any nature whatsoever;

                  (b) Such Selling Stockholder has duly executed and delivered
         an agreement and power of attorney (with respect to such Selling
         Stockholder, the "Agreement and Power-of-Attorney", in the form
         heretofore delivered to the Representatives, appointing [INSERT NAME OF
         ATTORNEY-IN-FACT] as such Selling Stockholder's attorney-in-fact (the
         "Attorney-in-Fact") with authority to execute, deliver and perform this
         Agreement on behalf of such Selling Stockholder and appointing [INSERT

         authority of the Attorney-in-Fact to execute and deliver this Agreement

         irrevocable and that the obligations of such Selling Stockholder
         hereunder shall not be terminated, except as provided in this Agreement
         or the Agreement and Power-of-Attorney, by any act of such Selling
         Stockholder, by operation of law, or otherwise, whether in the case of
         any individual Selling Stockholder by the death or incapacity of such
         Selling Stockholder, or in the case of a trust by its revocation or
         other termination or by the occurrence of any other event. If any
         individual Selling Stockholder should die or become incapacitated, or
         instrument governing a Selling Stockholder that is a trust shall have
         been revoked or any trustee shall have ceased to serve as such, or if
         any other event should occur, before the delivery of such Securities
         hereunder, the certificates for such Securities deposited with the
         Custodian shall be delivered by the Custodian in accordance with the
         respective terms and conditions of this Agreement as if such death,
         incapacity, termination, liquidation or dissolution or other event had
         not occurred, regardless of whether or not the Custodian or the
         Attorney-in-Fact shall have received notice thereof;

                  (c) Such Selling Stockholder will not, during the period of
         180 days after the date hereof, except pursuant to this Agreement,
         offer, sell, contract to sell, or otherwise dispose of any capital
         stock of the Company (or securities convertible into, or exchangeable
         for, capital stock of the Company), directly or indirectly, without the
         prior written consent of Schroder & Co. Inc., other than pursuant to
         bona fide gifts to persons or entities who agree in writing with you to
         be bound by the restrictions set forth in this paragraph;

         Agreement or the Agreement and Power-of-Attorney or the consummation of
         the transactions herein or therein contemplated nor the compliance with
         the terms hereof or thereof by such Selling Stockholder will conflict
         with, or result in a breach or violation of any of the terms and
         provisions of, or constitute a default under, or result in the creation
         or imposition of any lien, charge, claim or encumbrance on any property
         of the Company or any of its subsidiaries, under any indenture,
         mortgage, deed of trust, lease or other agreement or instrument to
         which such Selling Stockholder is a party or by which such Selling
         Stockholder's property is bound, or the instruments governing any
         Selling Stockholder that is a trust or any statute, ruling, judgment,

         authority or any arbitrator applicable to such Selling Stockholder; and
         no consent, approval, authorization, order, registration or
         qualification of or with any governmental authority, except such as

         securities or Blue Sky laws or by the by-laws and rules of the National
         Association of Securities Dealers, Inc. and, if the registration
         statement filed with respect to the Securities is not effective under
         the Act as of the time of execution hereof, such as may be required
         (and shall be obtained as provided in this Agreement) under the Act;

         reasonably be expected to constitute, the stabilization or manipulation
         of the price of any security of the Company;

                  (f) The sale by such Selling Stockholder of Securities
         pursuant hereto is not prompted by any adverse information concerning

         Prospectus;

                  (g) Such Selling Stockholder has reviewed the Prospectus and
         the Registration Statement, and the information regarding such Selling
         Stockholder set forth therein under the caption "Principal and Selling
         Stockholders" is complete and accurate;

                  (h) At the Time of Delivery, all stock transfer or other taxes

         offering and sale of the Securities; and

                  (j) Such Selling Stockholder (other than the Christine H.
         Holmes Trust) does not have any knowledge or any reason to believe that
         the Registration Statement or the Prospectus (or any amendment or
         supplement thereto) contains any untrue statement of a material fact or
         omits to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading.

         2. Subject to the terms and conditions herein set forth, the Company
agrees to issue and sell to the several Underwriters an aggregate of 1,300,000

Underwriters the number of Firm Securities set forth on Schedule II opposite the
name of such Selling Stockholder and each of the Underwriters agrees to purchase
from the Company and the Selling Stockholders, at a purchase price of
$__________ per share, the respective aggregate number of Firm Securities
determined in the manner set forth below. The obligation of each Underwriter to
the Company and each of the Selling Stockholders, respectively, shall be to
purchase that portion of the number of shares of Common Stock to be sold by the
Company or such Selling Stockholder pursuant to this Agreement as the number of
Firm Securities set forth opposite the name of such Underwriter on Schedule I
bears to the total number of Firm Securities to be purchased by the Underwriters
pursuant to this Agreement, in each case adjusted by you such that no
Underwriter shall be obligated to purchase Firm Securities other than in 100
share amounts. In making this Agreement, each Underwriter is contracting
severally and not jointly.

purpose of covering over-allotments in the sale of the Firm Securities), up to

written or telephonic notice (subsequently confirmed in writing) to the Company
of your determination to purchase all or a portion of the Option Securities.
Such notice may be given at any time within a period of 30 days following the
date of this Agreement. Option Securities shall be purchased severally for the
account of each Underwriter in proportion to the number of Firm Securities set
forth opposite the name of such Underwriter in Schedule I hereto. No Option
Securities shall be delivered to or for the accounts of the Underwriters unless
the Firm Securities shall be simultaneously delivered or shall theretofore have
been delivered as herein provided. The respective purchase obligations of each
Underwriter shall be adjusted by you so that no Underwriter shall be obligated
to purchase Option Securities other than in 100 share amounts. The Underwriters
may cancel any purchase of Option Securities at any time prior to the Option
Securities Delivery Date (as defined in Section 4 hereof) by giving written
notice of such cancellation to the Company.

                  occurred as a result of which the Prospectus as then amended

                  material fact or omit to state any material fact necessary in

                  appropriate filing under Section 13, 14 or 15(d) of the
                  Exchange Act which will correct such statement or omission or

                  of the Exchange Act subsequent to the Effective Date and
                  during any period when the Prospectus is required to be
                  delivered;

                  Date, to furnish to its stockholders after the end of each

                  light of the financial condition of the Company and its

                  case as amended to the date hereof, or any agreement or other
                  instrument known to such counsel; and no holders of securities
                  of the Company have rights to the registration thereof under
                  the Registration Statement or, if any such holders have such
                  rights, such holders have waived such rights;

                           (xiii) To the extent summarized therein, all
                  contracts and agreements summarized in the Registration

                  conform in all material respects to the descriptions thereof
                  contained therein, and, to the extent such contracts or
                  agreements or any other material agreements are required under
                  the Act or the rules and regulations thereunder to be filed or
                  incorporated by reference therein, as exhibits to the
                  Registration Statement, they are so filed or incorporated by
                  reference; and such counsel does not know of any contracts or
                  other documents required to be summarized or disclosed in the
                  Prospectus or to be so filed or incorporated by reference as
                  an exhibit to the Registration Statement, which have not been
                  so summarized or disclosed, or so filed or incorporated by
                  reference;

                           (xiv) All descriptions in the Prospectus of statutes,
                  regulations or legal or governmental proceedings are fair
                  summaries thereof and fairly present the information required
                  to be shown with respect to such matters;

                           (xv) Nothing has come to such counsel's attention to
                  give such counsel reason to believe that any of the
                  representations and warranties of the Company contained in
                  this Agreement or in any certificate or document contemplated
                  under this Agreement to be delivered are not true or correct
                  or that any of the covenants and agreements herein contained
                  to be performed on the part of the Company or any of the
                  conditions herein contained, or set forth in the Registration
                  Statement and the Prospectus, to be fulfilled or complied with
                  by the Company have not been or will not be duly and timely
                  performed, fulfilled or complied with; and

                  under the Act, the Prospectus has been filed in accordance
                  with Rule 424(b) of the rules and regulations of the
                  Commission under the Act, including the applicable time
                  periods set forth therein, or such filing is not required and,
                  to the best knowledge of such counsel, no stop order
                  suspending the effectiveness of the Registration Statement has
                  been issued and no proceedings for that purpose have been
                  instituted or are pending or threatened under the Act; the
                  Registration Statement, the Prospectus and each amendment or
                  supplement thereto, as of their respective effective or issue
                  dates, complied as to form in all material respects with the
                  requirements of the Act

                  the rules and regulations thereunder and the requirements of
                  Form S-3; the documents incorporated by reference in the
                  Prospectus comply as to form in all material respects with the
                  requirements of the Exchange Act and the rules and regulations
                  of the Commission thereunder; it being understood that such
                  counsel need express no opinion as to the financial statements
                  and schedules or other financial or statistical data contained
                  or incorporated by reference in the Registration Statement or
                  the Prospectus; and the conditions for use of Form S-3 set
                  forth in the General Instructions thereto have been satisfied
                  in the case of the Registration Statement.

         Such counsel shall also state that they have participated in the
preparation of the Registration Statement and the Prospectus as counsel to the
Company and during the preparation of the Registration Statement and the
Prospectus, they participated in conferences with representatives of the
independent public and internal accounts for, and other representatives of, the
Company and its subsidiaries, at which conferences the contents of the
Registration Statement and the Prospectus and related matters were discussed
and, while they have not confirmed the accuracy or completeness of or otherwise
verified the information contained in the Registration Statement or the
Prospectus, based upon such preparation and conferences and a review of
documents deemed relevant for the purpose of rendering their opinion, nothing
has come to their attention that would lead them to believe that (i) the
Registration Statement, as of the time it became effective under the Act,
contained or contains as of the date of such opinion any untrue statement of a
material fact or omitted or omits as of the date of such opinion to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, and (ii) the Prospectus and any amendments thereof or
supplements thereto (other than numerical, financial data, statistical data,
ratios, financial statements and notes thereto and related schedules therein, as
to which such counsel need express no belief), as of this date, contained or
contains as of the date of such opinion any untrue statement of material fact or
omitted or omits as of the date of such opinion to state any material fact
required to be stated therein or necessary to make the statement therein, in
light of the circumstances under which they were made, not misleading; provided,
however, such counsel need express no comment as to (i) the information in the
Prospectus under the caption "Underwriting," and (ii) the financial statements,
schedules and other numerical, financial, statistical data, or ratios contained
in the Registration Statement or the Prospectus.

         In rendering their opinions set forth in Section 7(d) above, such
counsel may rely, to the extent deemed advisable by such counsel, (a) as to
factual matters, upon certificates of public officials and officers of the
Company that have been provided to counsel for Underwriters, and (b) as to the
laws of any jurisdiction other than the United States and jurisdictions in which
they are admitted, on opinions of counsel (provided, however, that you shall
have received a copy of each of such opinions which shall be dated the Time of
Delivery, addressed to you or otherwise authorizing you to rely thereon, and
Company Counsel in its opinion to you delivered pursuant to this subsection,
shall state that such counsel are satisfactory to them and Company Counsel has
no reason to believe that the Underwriters and they are not justified to so
rely);

                  (e) With respect to each of the Selling Stockholders, Calfee,
         Halter & Griswold LLP, as counsel for the Selling Stockholders, shall
         have furnished to you their written opinion, dated the Time of
         Delivery, in form and substance satisfactory to you and to Arter &
         Hadden to the effect that:

                           (i) each Selling Stockholder has full legal right,
                  power and authority to enter into this Agreement and the
                  Agreement and Power-of-Attorney and to sell, transfer and
                  deliver the Securities being sold by such Selling Stockholder
                  hereunder in the manner provided in this Agreement and to
                  perform its obligations under the Agreement and
                  Power-of-Attorney; the execution and delivery of this
                  Agreement, and the Agreement and Power-of-Attorney have been
                  duly authorized by all necessary corporate action of each
                  Selling Stockholder; this Agreement and the Agreement and
                  Power-of-Attorney have been duly executed and delivered by
                  each Selling Stockholder; assuming due authorization,
                  execution and delivery by the Custodian, this Agreement and
                  the Agreement and Power-of-Attorney are legal, valid and
                  binding agreements of each Selling Stockholder, enforceable in
                  accordance with their terms, except as enforcement of the same
                  may be limited by bankruptcy, insolvency, reorganization,
                  moratorium or other similar laws affecting creditors' rights
                  generally and subject, as to enforceability, to general
                  principles of equity (regardless of whether enforcement is
                  sought in a proceeding in equity or at law);

                           (ii) upon delivery of and payment for the Securities
                  being sold by each Selling Stockholder, the several
                  Underwriters will receive good and valid title to such
                  Securities, free and clear of all liens, encumbrances,
                  equities, security interests, claims or other defects;

                           (iii) the sale of the Securities to the Underwriters
                  by the Selling Stockholders pursuant to this Agreement, the
                  compliance by the Selling Stockholders with the other
                  provisions of this Agreement and the Agreement and
                  Power-of-Attorney and the consummation of the other
                  transactions herein contemplated do not and will not (i)
                  conflict with, or result in a breach or violation of any of
                  the terms and provisions of, or constitute a default under, or
                  result in the creation or imposition of any lien, charge,
                  claim or encumbrance on any property of any Selling
                  Stockholder under, any indenture, mortgage, deed of trust,
                  lease or other agreement or instrument to which any Selling
                  Stockholder is a party or by which any Selling Stockholder or
                  any of the Selling Stockholders' property is bound, or any
                  instrument governing a trust that is a Selling Stockholder or
                  any statute or any judgment, decree, order, rule or regulation
                  of any court or other governmental authority or any arbitrator
                  applicable to any Selling Stockholder, or (ii) require the
                  consent, approval, authorization, order, registration or
                  qualification of or with any governmental authority, except
                  such as have been obtained and such as may be required under
                  state or foreign securities or Blue Sky laws; and







                                       25

                           (iv) there are no transfer or other taxes (other than
                  income taxes) known to such counsel payable in connection with
                  the sale and delivery of the Securities by the Selling
                  Stockholders to the several Underwriters or all such taxes
                  have been fully paid in connection with such sale and
                  delivery.

         In rendering such opinion, such counsel may rely, to the extent deemed
advisable by such counsel, as to factual matters, upon certificates of public
officials and the Selling Stockholders that have been provided to counsel to the
Underwriters.

                  (f) Arter & Hadden, counsel to the Underwriters, shall have
         furnished to you their written opinion or opinions, dated the Time of
         Delivery, in form and substance satisfactory to you, with respect to
         the incorporation of the Company, the validity of the Securities, the
         Registration Statement, the Prospectus and other related matters as you
         may reasonably request, and such counsel shall have received such
         papers and information as they may reasonably request to enable them to
         pass upon such matters;

                  (g) At the time this Agreement is executed and also at the
         Time of Delivery, Ernst & Young LLP shall have furnished to you a
         letter or letters, dated the date of this Agreement and the Time of
         Delivery, in form and substance satisfactory to you, to the effect,
         that:

                           (i) They are independent accountants with respect to
                  the Company and its subsidiaries within the meaning of the Act
                  and the applicable published rules and regulations of the
                  Commission applicable to such financial statements;

                           (ii) In their opinion the consolidated financial
                  statements of the Company and its subsidiaries (including the
                  related schedules and notes) and the consolidated financial
                  statements of Cryenco and its subsidiaries included or
                  incorporated by reference in the Registration Statement and
                  Prospectus and covered by their reports included or
                  incorporated by reference therein comply as to form in all
                  material respects with the applicable accounting requirements
                  of the Act or the Exchange Act, as applicable, and the
                  published rules and regulations thereunder;

                           (iii) On the basis of specified procedures as of a
                  specified date not more than five days prior to the date of
                  their letter (which procedures do not constitute an
                  examination made in accordance with generally accepted
                  auditing standards), consisting of a reading of the latest
                  available unaudited interim consolidated financial statements
                  of the Company and its subsidiaries, a reading of the latest
                  available minutes of any meeting of the Board of Directors and
                  stockholders of the Company and its subsidiaries since the
                  date of the latest audited financial statements included or
                  incorporated by reference in the Prospectus, inquiries of
                  officials of the Company and its subsidiaries who have
                  responsibility for financial and accounting matters, and such
                  other procedures or inquiries as are specified in such letter,
                  nothing came to their attention that caused them to believe
                  that:

<PAGE>   27

                                    (A) The unaudited consolidated condensed
                           financial statements of the Company and its
                           subsidiaries included in the Prospectus do not comply
                           in form in all material respects with the applicable
                           accounting requirements of the Act and the rules and
                           regulations promulgated thereunder or are not
                           presented in conformity with generally accepted
                           accounting principles applied on a basis
                           substantially consistent with that of the audited
                           consolidated financial statements included in the
                           Registration Statement and the Prospectus;

                                    (B) as of a specified date not more than
                           five days prior to the date of their letter, there
                           was any change in the capital stock, or the long-term
                           debt or short-term debt of the Company and its
                           subsidiaries on a consolidated basis, or any decrease
                           in total assets, net current assets, or shareholders'
                           equity or other items specified by the
                           Representatives, of the Company and its subsidiaries
                           on a consolidated basis, each as compared with the
                           amounts shown on the balance sheet as of June 30,
                           1997 included in the Registration Statement and the
                           Prospectus, except in each case for changes,
                           increases or decreases which the Prospectus discloses
                           have occurred or may occur or such other changes,
                           decreases or increases which are described in their
                           letter and which do not, in the sole judgment of the
                           Representatives, make it impractical or inadvisable
                           to proceed with the purchase and delivery of the
                           Securities as contemplated by the Registration
                           Statement; and

                                    (C) for the period from July 1, 1997 to a
                           specified date not more than five days prior to the
                           date of such letter, there was any decrease, as
                           compared with the corresponding period of the
                           preceding fiscal year, in the following consolidated
                           amounts: sales, income from operations, income before
                           provision for income taxes, net income or net income
                           per share of the Company and its subsidiaries, except
                           in all instances for decreases which the Registration
                           Statement discloses have occurred or may occur; or
                           such other decreases which are described in their
                           letter and which do not, in the sole judgment of the
                           Representatives, make it impractical or inadvisable
                           to proceed with the purchase and delivery of the
                           Securities as contemplated by the Registration
                           Statement, and

                           (iv) in addition to the examination referred to in
                  their reports included in the Registration Statement and the
                  Prospectus and the limited procedures referred to in clause
                  (iii) above, they have carried out certain specified
                  procedures, not constituting an audit, with respect to certain
                  amounts, percentages and financial information specified by
                  the Representatives, which are derived from the general
                  accounting records of the Company and its subsidiaries which
                  appear in the Prospectus, or in Part II of, or in exhibits and
                  schedules to, the Registration Statement, (b) the Company's
                  Annual Report on Form 10-K for the year ended December 31,
                  1996, under Items 1, 6 and 7, (c) the Company's Quarterly
                  Reports on Form 10-Q for the quarters ended March 31 and June
                  30, 1997 under Items 1 and 2 



                                       27

                  of Part I, and (d) the Company's Current Reports on Form 8-K
                  dated July 31, 1997 under Items 2 and 7, and have compared
                  such amounts and financial information with the accounting
                  records of the Company and its subsidiaries, and have found
                  them to be in agreement and have proved the mathematical
                  accuracy of certain specified percentages.

                           (v) On the basis of a reading of the pro forma
                  consolidated financial statements included in the Registration
                  Statement and the Prospectus, carrying out certain specified
                  procedures that would not necessarily reveal matters of
                  significance with respect to the comments set forth in this
                  clause (v), inquiries of certain officials of the Company and
                  its consolidated subsidiaries and Cryenco who have
                  responsibility for financial and accounting matters and
                  proving the arithmetic accuracy of the application of the pro
                  forma adjustments to the historical amounts in the pro forma
                  consolidated financial statements, nothing came to their
                  attention that caused them to believe that the pro forma
                  consolidated financial statements do not comply in form in all
                  material respects with the applicable accounting requirements
                  of Rule 11-02 of Regulation S-X or that the pro forma
                  adjustments have not been properly applied to the historical
                  amounts in the compilation of such statements.

                  (h) Neither the Company nor any of its subsidiaries shall have
         sustained since the date of the latest audited financial statements
         included or incorporated by reference in the Prospectus, any loss or
         interference with its business from fire, explosion, flood or other
         calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree; and since the
         respective dates as of which information is given in the Prospectus,
         there shall not have been any change in the capital stock (other than
         shares issued pursuant to the exercise of Stock Option Shares or
         pursuant to the terms of warrants of the Company described in the
         Prospectus as outstanding on the date hereof) or short-term debt or
         long-term debt of the Company or any of its subsidiaries nor any change
         or any development involving a prospective change, in or affecting the
         general affairs, management, financial condition, shareholders' equity
         or results of operations of the Company and its subsidiaries, otherwise
         than as set forth or contemplated in the Prospectus, the effect of
         which, in any such case is in your judgment so material and adverse as
         to make it impracticable or inadvisable to proceed with the public
         offering or the delivery of the Securities on the terms and in the
         manner contemplated in the Prospectus;

                  (i) Between the date hereof and the Time of Delivery there
         shall have been no declaration of war by the Government of the United
         States; at the Time of Delivery there shall not have occurred any
         material adverse change in the financial or securities markets in the
         United States or in political, financial or economic conditions in the
         United States or any outbreak or material escalation of hostilities or
         other calamity or crisis, the effect of which is such as to make it, in
         the judgment of the Representatives, impracticable to market the
         Securities or to enforce contracts for the resale of Securities and no
         event shall have occurred resulting in (i) trading in securities
         generally on the New York Stock Exchange or in the Common Stock on the
         New York Stock Exchange being suspended or limited or minimum or
         maximum prices being generally established on such exchange, or (ii)

         additional material restrictions, not in force on the date of this
         Agreement, being imposed upon trading in securities generally (or the
         Common Stock specifically) by the New York Stock Exchange or by order
         of the Commission or any court or other governmental authority, or
         (iii) a general banking moratorium being declared by either Federal or
         New York authorities;

                  (j) The Company and the Selling Stockholders shall have
         furnished or caused to be furnished to you at the Time of Delivery
         certificates signed by the chief executive officer and the chief
         financial officer, on behalf of the Company, and by each Selling
         Stockholder satisfactory to you as to such matters as you may
         reasonably request and as to (i) the accuracy of its and their
         respective representations and warranties herein at and as of the Time
         of Delivery and (ii) the performance by the Company and each Selling
         Stockholder of all their respective obligations hereunder to be
         performed at or prior to the Time of Delivery; the Company and the
         Selling Stockholders shall have furnished or caused to be furnished to
         you at the Time of Delivery certificates signed by the chief executive
         officer and the chief financial officer, on behalf of the Company, and
         by each Selling Stockholder as to (i) the fact that they have carefully
         examined the Registration Statement and Prospectus and, (a) as of the
         Effective Date, the statements contained or incorporated by reference
         in the Registration Statement and the Prospectus were true and correct
         and neither the Registration Statement nor the Prospectus omitted to
         state a material fact required to be stated therein or necessary to
         make the statements therein not misleading (except that each Selling
         Stockholder shall be responsible only for information relating to it or
         required to be disclosed by it) and (b) since the Effective Date, no
         event has occurred that is required by the Act or the rules and
         regulations of the Commission thereunder to be set forth in an
         amendment of, or a supplement to, the Prospectus that has not been set
         forth in such an amendment or supplement; and (ii) the matters set
         forth in subsection (a) of this Section 7;

                  (k) Each director and executive officer of the Company and
         each Selling Stockholder shall have delivered to you an agreement not
         to offer, sell, contract to sell or otherwise dispose of any shares of
         capital stock of the Company (or securities convertible into, or
         exchangeable for, capital stock of the Company), directly or
         indirectly, for a period of 180 days after the date of this Agreement,
         without the prior written consent of Schroder & Co. Inc.;

                  (l) The Company shall have delivered to you evidence that the
         Securities have been authorized for additional listing on the New York
         Stock Exchange as of the Effective Date; and

                  (m) The Company shall have delivered to you evidence,
         satisfactory to you and your counsel, that the New Credit Facility (as
         defined in the Prospectus) has been modified or amended (i) to permit
         the offer and sale of the Securities as contemplated hereby; (ii) to
         permit a maximum aggregate $6.0 million of dividends to be authorized

         conditions of the New Credit Facility; and (iii) to require Charles S.
         Holmes and Arthur S. Holmes to own, together in the aggregate, not less
         than 20% of the Company's equity securities on a fully diluted basis.

         8. (a) The Company will indemnify, defend and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act 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 a material fact contained or incorporated by
reference in any Preliminary Prospectus, the Registration Statement or the
Prospectus, or any amendment or supplement thereto, or in any Blue Sky
application or other document executed by the Company specifically for that
purpose or based upon information furnished by the Company filed in any state or
other jurisdiction in order to qualify any or all of the Securities under the
securities laws thereof or filed with the Commission or any securities
association or securities exchange (each, an "Application"), or the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements made or incorporated by reference therein
not misleading, or (ii) any untrue statement or alleged untrue statement made by
the Company in Section 1A of this Agreement, or (iii) the employment by the
Company of any device, scheme or artifice to defraud, or the engaging by the
Company in any act, practice or course of business which operates or would
operate as a fraud or deceit, or any conspiracy with respect thereto, in which
the Company shall participate, in connection with the issuance and sale of any
of the Securities, and will reimburse each Underwriter for any legal or other
expenses reasonably incurred by such Underwriter in connection with
investigating, preparing to defend, defending or appearing as a third-party
witness in connection with any such action or claim; provided, however, that the
Company shall 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 relating to an
Underwriter made in any Preliminary Prospectus, the Registration Statement, the
Prospectus or such amendment or supplement or any Application in reliance upon
and in conformity with written information furnished to the Company by such
Underwriter through you expressly for use therein, provided, further, that the
indemnity agreement contained in this Section 8(a) with respect to any
Preliminary Prospectus shall not inure to the benefit of any Underwriter (or any
persons controlling such Underwriter) on account of any losses, claims, damages,
liabilities or litigation arising from the sale of Securities to any person, if
such Underwriter fails to send or give a copy of the Prospectus, as the same may
be then supplemented or amended, to such person, within the time required by the
Act and the untrue statement or alleged untrue statement or omission or alleged
omission of a material fact contained in such Preliminary Prospectus was
corrected in the Prospectus, unless such failure is the result of noncompliance
by the Company with Section 5(a)(iii) hereof.

                  (b) Each Selling Stockholder, severally and not jointly, will
indemnify, defend and hold harmless each Underwriter, the Company and the other
Selling Stockholders against any losses, claims, damages or liabilities to which
such Underwriter, the Company or such other Selling Stockholders may become
subject under the Act 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 a material fact contained or
incorporated by reference in the Preliminary Prospectus, the Registration
Statement, or the Prospectus, or any amendment or supplement thereto, or the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements made or incorporated by
reference therein not 



                                       30
<PAGE>   31

misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in the Preliminary Prospectus, the Registration Statement, the Prospectus or
such amendment or supplement in reliance upon and in conformity with information
furnished to such Underwriter or the Company by such Selling Stockholder in
writing expressly for use therein, or (ii) any untrue statement or alleged
untrue statement made by such Selling Stockholder in Section 1B of this
Agreement, and will reimburse such Underwriter, the Company or such other
Selling Stockholders for any legal or other expenses incurred by such
Underwriter, the Company or such other Selling Stockholders in connection with
investigating, preparing to defend, defending or appearing as a third-party
witness in connection with any such action or claim; provided, however, that the
indemnity agreement contained in this Section 8(b) with respect to any
Preliminary Prospectus shall not inure to the benefit of any Underwriter (or any
persons controlling such Underwriter) on account of any losses, claims, damages,
liabilities or litigation arising from the sale of Securities to any person, if
such Underwriter fails to send or give a copy of the Prospectus, as the same may
be then supplemented or amended, to such person within the time required by the
Act and the untrue statement or alleged untrue statement or omission or alleged
omission of a material fact contained in such Preliminary Prospectus was
corrected in the Prospectus, unless such failure is the result of noncompliance
by the Company with Section 5(a)(iii) hereof; provided, further, no Seller
Stockholder against whom a claim for indemnity is made on the basis of the
provisions of this Section 8(b) shall be required to indemnify, hold harmless or
reimburse the Company or Underwriters in an aggregate amount in excess of the
proceeds received by the Selling Stockholder in connection herewith.

                  (c) In addition to any obligations of the Company and each of
the Selling Stockholders under Section 8(a) and 8(b), the Company and each of
the Selling Stockholders agree that they shall perform their indemnification
obligations under Section 8(a) and Section 8(b) with respect to counsel fees and
expenses and other expenses reasonably incurred by making payments within 45
days to the Underwriter in the amount of the statements of the Underwriter's
counsel or other statements which shall be forwarded by the Underwriter, and
that it shall make such payments notwithstanding the absence of a judicial
determination as to the propriety and enforceability of the obligation to
reimburse the Underwriters for such expenses and the possibility that such
payments might later be held to have been improper by a court until such time as
a court orders return of such payments.

         The indemnity agreement in Section 8(a) and Section 8(b) shall extend
upon the same terms and conditions to each person, if any, who controls any
Underwriter within the meaning of the Act or the Exchange Act.

                  (d) Each Underwriter will indemnify and hold harmless the
Company and the Selling Stockholders against any losses, claims, damages or
liabilities to which the Company or such Selling Stockholder may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or any Application, 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



                                       31
<PAGE>   32

misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in any Preliminary Prospectus, the Registration Statement, the Prospectus or
such amendment or supplement or any Application in reliance upon and in
conformity with written information furnished to the Company or such Selling
Stockholder by such Underwriter relating to such Underwriter through you
expressly for use therein, and will reimburse the Company or such Selling
Stockholder for any legal or other expenses reasonably incurred by the Company
or such Selling Stockholder in connection with investigating or defending any
such action or claim.

         The indemnity agreement in this Section 8(d) shall be in addition to
any liability which the respective Underwriters may otherwise have and shall
extend, upon the same terms and conditions, to each officer and director of the
Company or of any Selling Stockholder and to each person, if any, who controls
the Company or any Selling Stockholder within the meaning of the Act or the
Exchange Act.

                  (e) Promptly after receipt by an indemnified party under
Section 8(a), 8(b) or 8(d) of notice of the commencement of any action
(including any governmental investigation), such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party under such
subsection, notify the indemnifying party in writing of the commencement
thereof; but the omission so to notify the indemnifying party shall not relieve
it from any liability which it may have to any indemnified party under Section
8(a), 8(b) or 8(d) except to the extent it was unaware of such action and has
been prejudiced in any material respect by such failure or from any liability
which it may have to any indemnified party otherwise than under such Section
8(a), 8(b) or 8(d). 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 therein and, to
the extent that it shall wish, jointly with any other indemnifying party
similarly notified, to assume 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 the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
subsection for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. If, however, (i) the indemnifying party has authorized
the employment of counsel for the indemnified party at the expense of the
indemnifying party or (ii) an indemnified party shall have reasonably concluded
that representation of such indemnified party and the indemnifying party by the
same counsel would be inappropriate under applicable standards of professional
conduct due to actual or potential differing interests between them and the
indemnified party so notifies the indemnifying party, then the indemnified party
shall be entitled to employ counsel different from counsel for the indemnifying
party at the expense of the indemnifying party and the indemnifying party shall
not have the right to assume the defense of such indemnified party. In no event
shall the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to local counsel) for all indemnified parties in connection
with any one action or separate but similar or related actions in the same
jurisdiction arising out of the same set of allegations or circumstances. The
counsel with respect to which fees and expenses shall be so reimbursed shall be
designated in writing by Schroder & Co. Inc. in the case of parties indemnified
pursuant to Section 8(a) and Section 8(b) and by the Company in the case of
parties indemnified pursuant to Section 8(d).




                                       32
<PAGE>   33

         If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel as contemplated by Section 8(c), the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

                  (f) In order to provide for just and equitable contribution
under the Act in any case in which (i) any Underwriter (or any person who
controls any Underwriter within the meaning of the Act or the Exchange Act)
makes claim for indemnification pursuant to Section 8(a) or Section 8(b) hereof,
but is judicially determined (by the entry of a final judgment or decree by a
court of competent jurisdiction and the expiration of time 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 Section 8(a) or Section 8(b)
provides for indemnification in such case or (ii) contribution under the Act may
be required on the part of any Underwriter or any such controlling person in
circumstances for which indemnification is provided under Section 8(d), then,
and in each such case, each indemnifying party shall contribute to the aggregate
losses, claims, damages or liabilities to which they may be subject as an
indemnifying party hereunder (after contribution from others) in such proportion
as is appropriate to reflect the relative benefits received by the Company and
the Selling Stockholders on the one hand and the Underwriters on the other from
the offering of the Securities. If, however, the allocation provided by the
immediately preceding sentence is not permitted by applicable law or if the
indemnified party failed to give the notice required under Section 8(e) above,
then each indemnifying party shall contribute to such amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect not only
such relative benefits but also the relative fault of the Company and the
Selling Stockholders on the one hand and the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the
Company and the Selling Stockholders on the one hand and the Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering of the Securities purchased under this Agreement (before
deducting expenses) received by the Company and the Selling Stockholders bear to
the total underwriting discounts and commissions received by the Underwriters
with respect to the Securities purchased under this Agreement, in each case as
set forth in the table on the cover page of the Prospectus. The relative fault
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company or the
Selling Stockholders on the one hand or the Underwriters on the other and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Company, each of the Selling
Stockholders and the Underwriters agree that it would not be just 



                                       33
<PAGE>   34

and equitable if contributions pursuant to this Section 8(f) were determined by
pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 8(f). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this Section 8(f) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 8(f), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Securities
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of a fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations in this Section 8(f) to contribute are several in
proportion to their respective underwriting obligations and not joint.

                  (g) Promptly after receipt by any party to this Agreement of
notice of the commencement of any action, suit or proceeding, such party will,
if a claim for contribution in respect thereof is to be made against another
party (the "contributing party"), notify the contributing party of the
commencement thereof; but the omission so to notify the contributing party will
not relieve it from any liability which it may have to any other party for
contribution under the Act except to the extent it was unaware of such action
and has been prejudiced in any material respect by such failure or from any
liability which it may have to any other party other than for contribution under
the Act. In case any such action, suit or proceeding is brought against any
party, and such party notifies a contributing party of the commencement thereof,
the contributing party will be entitled to participate therein with the
notifying party and any other contributing party similarly notified.

         9. (a) If any Underwriter shall default in its obligation to purchase
the Firm Securities which it has agreed to purchase hereunder, you may in your
discretion arrange for you or another party or other parties to purchase such
Firm Securities on the terms contained herein. If the aggregate number of Firm
Securities as to which Underwriters default is more than one-eleventh of the
aggregate number of all the Firm Securities and within 36 hours after such
default by any Underwriter you do not arrange for the purchase of such Firm
Securities, then the Company and the Selling Stockholders shall be entitled to a
further period of 36 hours within which to procure another party or other
parties satisfactory to you to purchase such Firm Securities on such terms. In
the event that, within the respective prescribed periods, you notify the Company
and the Selling Stockholders that you have so arranged for the purchase of such
Firm Securities, or the Company and the Selling Stockholders notify you that
they have so arranged for the purchase of such Firm Securities, you or the
Company shall have the right to postpone the Time of Delivery for a period of
not more than seven days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement or the Prospectus or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments to the Registration Statement or the Prospectus which in your opinion
may thereby be made necessary. The term "Underwriter" as used in this 



                                       34
<PAGE>   35

Agreement shall include any person substituted under this Section with like
effect as if such person had originally been a party to this Agreement with
respect to such Firm Securities.

                  (b) If, after giving effect to any arrangements for the
purchase of the Firm Securities of such defaulting Underwriter or Underwriters
by you or the Company and the Selling Stockholders or both as provided in
subsection (a) above, the aggregate number of such Firm Securities which remain
unpurchased does not exceed one-eleventh of the aggregate number of all the Firm
Securities, then the Company and the Selling Stockholders shall have the right
to require each non-defaulting Underwriter to purchase the number of the Firm
Securities which such Underwriter agreed to purchase hereunder and, in addition,
to require each non-defaulting Underwriter to purchase its pro rata share (based
on the number of Firm Securities which such Underwriter agreed to purchase
hereunder) of the Firm Securities of such defaulting Underwriter or Underwriters
for which such arrangements have not been made; but nothing shall relieve a
defaulting Underwriter from liability for its default.

                  (c) If, after giving effect to any arrangements for the
purchase of the Firm Securities of a defaulting Underwriter or Underwriters by
you or the Company and the Selling Stockholders as provided in subsection (a)
above, the aggregate number of such Firm Securities which remain unpurchased
exceeds one-eleventh of the aggregate number of all the Firm Securities, or if
the Company and the Selling Stockholders shall not exercise the right described
in subsection (b) above to require non-defaulting Underwriters to purchase Firm
Securities of a defaulting Underwriter or Underwriters, then this Agreement
shall thereupon terminate without liability on the part of any non-defaulting
Underwriter, the Company or any Selling Stockholder, except for the expenses to
be borne by the Company and the Selling Stockholders and the Underwriters as
provided in Section 6 hereof and the indemnity agreement in Section 8 hereof;
but nothing herein shall relieve a defaulting Underwriter from liability for its
default.

         10. The respective indemnities, agreements, representations, warranties
and other statements of the Company, each of the Selling Stockholders and the
several Underwriters, as set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement, shall remain in full force and
effect, regardless of any investigation (or any statement as to the results
thereof) made by or on behalf of any Underwriter or any controlling person of
any Underwriter, or the Company, or an officer or director or controlling person
of the Company, or any of the Selling Stockholders, or any controlling person of
any of the Selling Stockholders, and shall survive delivery of and payment for
the Securities.

         11. This Agreement shall become effective (a) if the Registration
Statement has not heretofore become effective, at the earlier of 12:00 Noon, New
York City time, on the first full business day after the Registration Statement
becomes effective, or at such time after the Registration Statement becomes
effective as you may authorize the sale of the Securities to the public by
Underwriters or other securities dealers, or (b) if the Registration Statement
has heretofore become effective, at the earlier of 24 hours after the filing of
the Prospectus with the Commission or at such time as you may authorize the sale
of the Securities to the public by Underwriters or securities dealers, unless,
prior to any such time you shall have received notice from the Company that it
elects that this Agreement shall not become effective, or you, or through 



                                       35
<PAGE>   36

you such of the Underwriters as have agreed to purchase in the aggregate fifty
percent or more of the Firm Securities hereunder, shall have given notice to the
Company that you or such Underwriters elect that this Agreement shall not become
effective; provided, however, that the provisions of this Section and Section 6
and Section 8 hereof shall at all times be effective.

         If this Agreement shall be terminated pursuant to Section 9 hereof, or
if this Agreement, by election of you or the Underwriters, shall not become
effective pursuant to the provisions of this Section, the Company and the
Selling Stockholders shall not then be under any liability to any Underwriter
except as provided in Section 6 and Section 8 hereof, but if this Agreement
becomes effective and is not so terminated but the Securities are not delivered
by or on behalf of the Company or any of the Selling Stockholders as provided
herein because the Company or any of the Selling Stockholders has been unable
for any reason beyond its control and not due to any default by it to comply
with the terms and conditions hereof, the Company will reimburse the
Underwriters through you for all out-of-pocket expenses approved in writing by
you, including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Securities, but the Company and the Selling Stockholders shall then be under no
further liability to any Underwriter except as provided in Section 6 and Section
8 hereof.

         12. The statements set forth in the last paragraph on the front cover
page of the Prospectus, the paragraph on the inside front cover of the
Prospectus containing stabilization language and the second and seventh
paragraphs under the caption "Underwriting" in the Prospectus constitute the
only information furnished by any Underwriter through the Representatives to the
Company for purposes of Sections 1A(b), 1A(c) and 8 hereof.

         13. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Schroder & Co. Inc. on behalf of you as the
Representatives, and in all dealings with the Selling Stockholders hereunder,
you and the Company shall be entitled to act and rely upon any statement,
request, notice or agreement furnished in writing by or on behalf of such
Selling Stockholder or made or given by the Attorney-in-Fact for such Selling
Stockholder.

         All statements, requests, notices and agreements hereunder, unless
otherwise specified in this Agreement, shall be in writing and, if to the
Underwriters, shall be delivered or sent by mail, telex or facsimile
transmission (subsequently confirmed by delivery or by letter sent by mail) to
you as the Representatives in care of Schroder & Co. Inc., Equitable Center, 787
Seventh Avenue, New York, New York 10019, Attention: Syndicate Department; and
if to the Company or the Selling Stockholders, shall be delivered or sent by
letter sent by mail, telex or facsimile transmission (subsequently confirmed by
delivery or by letter sent by mail) to the address of the Company set forth in
the Registration Statement, Attention: Chief Executive Officer; PROVIDED,
HOWEVER, that any notice to any Underwriter pursuant to Section 8(d) hereof
shall be delivered or sent by mail, telex or facsimile transmission
(subsequently confirmed by delivery or by letter sent by mail) to such
Underwriter at its address set forth in its Underwriters' Questionnaire, or
telex constituting 


                                       36
<PAGE>   37

such Questionnaire, which address will be supplied to the Company by you upon
request. Any such statements, requests, notices or agreements shall take effect
at the time of receipt thereof.

         14. This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company and each of the Selling Stockholders
and, to the extent provided in Section 8 and Section 10 hereof, the officers and
directors of the Company and each person who controls the Company, any Selling
Stockholder or any Underwriter, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement. No purchaser of any of the
Securities from any Underwriter shall be deemed a successor or assign by reason
merely of such purchase.

         15. Time shall be of the essence of this Agreement. As used herein, the
