or other agreement or instrument known to such counsel to which the Company or
any of its subsidiaries is a party or by which the Company or any of its

the Company or any statute applicable to the Company or its subsidiaries or any
order naming the Company or its subsidiaries, or rule or regulation known to
such counsel of any court or governmental agency or body having jurisdiction
over the Company or any of its subsidiaries or any of their properties;

LLP, such opinion shall also state that the Registration Statement and the
Prospectus and any further amendments and supplements thereto made by the
Company prior to such Time of Delivery (other than the financial statements and
related schedules and other financial data contained therein, as to which such
counsel need express no opinion) comply as to form in all material respects with
the requirements of the Act and the rules and regulations thereunder; although
they do not assume any responsibility for the accuracy, completeness or fairness
of the statements contained in the Registration Statement or the Prospectus, no
facts have come to such counsel's attention that have caused such counsel to
believe that, as of its effective date, the Registration Statement or any

                                       14


contained therein, as to which such counsel need express no opinion) contained
an untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading or that, as of its date, the Prospectus or any further amendment or
supplement thereto made by the Company prior to such Time of Delivery (other
than the financial statements and related schedules and other financial data
contained therein, as to which such counsel need express no opinion) contained
an untrue statement of a material fact or omitted to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading or that, as of such Time of Delivery,
either the Registration Statement or the Prospectus or any further amendment or
supplement thereto made by the Company prior to such Time of Delivery (other
than the financial statements and related schedules and other financial data
contained therein, as to which such counsel need express no opinion) contains an
untrue statement of a material fact or omits to state a material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading; and they do not know of any amendment to the
Registration Statement required to be filed or of any contracts or other
documents of a character required to be filed as an exhibit to the Registration

Agreement and the Registrant Statement) each shall have furnished to you their
written opinion with respect to each of the Selling Stockholders for whom they

satisfactory to you, to the effect that:

                           (i) A Power-of-Attorney and a Custody Agreement have
been duly executed and delivered by such Selling Stockholder and constitute
valid and binding agreements of such Selling Stockholder enforceable against
such Selling Stockholder in accordance with their respective terms;


                           (ii) This Agreement has been duly executed and
delivered by or on behalf of such Selling Stockholder; and the sale of the
Shares to be sold by such Selling Stockholder hereunder and the compliance by
such Selling Stockholder with all of the provisions of this Agreement, the
Power-of-Attorney and the Custody Agreement and the consummation of the
transactions herein and therein contemplated will not conflict with or result in
a breach or violation of any terms or provisions of, or constitute a default
under, any statute, indenture, mortgage, deed of trust, loan agreement or other
agreement or instrument known to such counsel to which such Selling Stockholder
is a party or by which such Selling Stockholder is bound or to which any of the
property or assets of such Selling Stockholder is subject, nor will such action
result in any violation of the provisions of the Certificate of Incorporation or
By-laws of such Selling Stockholder if such Selling Stockholder is a
corporation, the Partnership Agreement of such Selling Stockholder if such
Selling Stockholder is a partnership (or certificate of limited partnership of
such Selling Stockholder if such Selling Stockholder is a limited partnership),
Articles of Organization or LLC Agreement (or Operating Agreement) of such
Selling Stockholder if such Selling Stockholder is a limited liability company
or any order specifically applicable to such Selling Stockholder, rule or
regulation known to such counsel of any court or governmental agency

                                       15


or body having jurisdiction over such Selling Stockholder or the property of
such Selling Stockholder;

                           (iii) No consent, approval, authorization or order of
any court or governmental agency or body is required for the consummation of the
transactions contemplated by this Agreement in connection with the Shares to be
sold by such Selling Stockholder hereunder, except such as have been obtained

laws in connection with the purchase and distribution of such Shares by the
Underwriters;

                           (iv) Immediately prior to such Time of Delivery based
on an examination of the Company's stock record books, such Selling Stockholder
was the sole record holder of the Shares to be sold by such Selling Stockholder
under this Agreement, free and clear of all liens, encumbrances, equities or
claims, and full right, power and authority to sell, assign, transfer and
deliver the Shares to be sold by such Selling Stockholder hereunder; and 

                           (v) Assuming that the Underwriters are bona fide
purchasers purchasing in good faith without notice of any adverse claim within
the meaning of the Uniform Commercial Code, upon the delivery of and payment for
the Shares to be sold by such Selling Stockholders as contemplated by this
Agreement, each of the Underwriters will acquire the Shares purchased by it from
such Selling Stockholders free of any adverse claims. 

         In rendering the opinion in paragraph (iv), such counsel may rely upon
a certificate of such Selling Stockholder in respect of matters of fact as to
ownership of, and liens, encumbrances, equities or claims on, the Shares sold by
such Selling Stockholder, provided that such counsel shall state that they
believe that both you and they are justified in relying upon such certificate;

                  (e) On the date of the Prospectus at a time prior to the
execution of this Agreement, at 9:30 a.m., New York City time, on the effective
date of any post-effective amendment to the Registration Statement filed

included 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, otherwise
than as set forth or contemplated in the Prospectus, and (ii) 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 as a result of the
exercise of stock options or warrants outstanding as of such dates) or long-term
debt of the Company or any of its subsidiaries or any change, or any development
involving a prospective change, in or affecting the general affairs, management,
financial position,


                                       16


stockholders' 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 described in Clause (i) or (ii), is in the
judgment of the Representatives so material and adverse as to make it

of the Shares being delivered at such Time of Delivery on the terms and in the
manner contemplated in the Prospectus;

                  (g) On or after the date hereof there shall not have occurred

offering or the delivery of the Shares being delivered at such Time of Delivery
on the terms and in the manner contemplated in the Prospectus;

furnished or caused to be furnished to you at such Time of Delivery certificates
of officers of the Company and of the Selling Stockholders, respectively,

                  (b) Each Underwriter will indemnify and hold harmless the
Company and each Selling Stockholder against any losses, claims, damages or

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

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 or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through Goldman, Sachs & Co.
expressly for use therein; and will reimburse the Company and each 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 as such expenses are incurred.

                  (c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above 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 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 otherwise than under such subsection. 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 (who shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
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 

                                       18


be liable to such indemnified party under such subsection for any legal expenses
of other counsel or any other expenses, in each case subsequently incurred by
such indemnified party, in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of any indemnified party.


                  (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) 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 Shares. 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 subsection (c) 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 (before deducting
expenses) received by the Company and the Selling Stockholders bear to the total
underwriting discounts and commissions received by the Underwriters, 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 and
equitable if contributions pursuant to this subsection (d) 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 subsection (d). 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 subsection (d) 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
subsection (d), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Shares underwritten
by 

                                       19


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 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 subsection (d) to contribute are several in proportion to
their respective underwriting obligations and not joint; provided further,
however, that (i) the aggregate liability of each Selling Stockholder pursuant
to this Subsection 8(d) and Subsection 8(a) above shall not exceed the product
of the number of Shares sold by such Selling Stockholder and the initial public
offering price of the Shares as set forth in the Prospectus and (ii) no Selling
Stockholder shall be required to provide contribution hereunder with respect
to any loss, claim, damage or liability in respect of which it was not required
to provide indemnification above under this Section 8 (other than if such
indemnification was not required because indemnification in the subject
circumstances was unavailable to the indemnified party as a matter of law or
public policy, or the inability to enforce the above provisions of Section 8).

                  (e) The obligations of the Company and the Selling
Stockholders under this Section 8 shall be in addition to any liability which
the Company and the respective Selling Stockholders may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who controls
any Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 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 and to each
person, if any, who controls the Company or any Selling Stockholder within the
meaning of the Act.

         9. (a) If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within thirty-six hours
after such default by any Underwriter you do not arrange for the purchase of
such Shares, then the Company and the Selling Stockholders shall be entitled to
a further period of thirty-six hours within which to procure another party or
other parties satisfactory to you to purchase such Shares 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
Shares, or the Company and the Selling Stockholders notify you that they have so
arranged for the purchase of such Shares, you or the Company and the Selling
Stockholders shall have the right to postpone a 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 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
Shares.

                  (b) If, after giving effect to any arrangements for the
purchase of the Shares of a defaulting Underwriter or Underwriters by you and
the Company and the Selling Stockholders as provided in subsection (a) above,
the aggregate number of such Shares which remains unpurchased does not exceed
one-eleventh of the aggregate number of all the Shares to be purchased at such
Time of Delivery, then the Company and the Selling Stockholders shall have the
right to require each non-defaulting Underwriter to purchase the number of
Shares which such Underwriter agreed to purchase hereunder at such Time of
Delivery and, in addition, to require 

                                       20


each non-defaulting Underwriter to purchase its pro rata share (based on the
number of Shares which such Underwriter agreed to purchase hereunder) of the
Shares of such defaulting Underwriter or Underwriters for which such
arrangements have not been made; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.

                  (c) If, after giving effect to any arrangements for the
purchase of the Shares of a defaulting Underwriter or Underwriters by you and
the Company and the Selling Stockholders as provided in subsection (a) above,
the aggregate number of such Shares which remains unpurchased exceeds
one-eleventh of the aggregate number of all of the Shares to be purchased at
such Time of Delivery, 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 Shares of a defaulting Underwriter or Underwriters,
then this Agreement (or, with respect to the Second Time of Delivery, the
obligations of the Underwriters to purchase and of the Company and the Selling
Stockholders to sell the Optional Shares) shall thereupon terminate, without
liability on the part of any non-defaulting Underwriter or the Company or the
Selling Stockholders, 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 and contribution agreements 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, 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 any of the Selling Stockholders, or any officer
or director or controlling person of the Company, or any controlling person of
any Selling Stockholder, and shall survive delivery of and payment for the
Shares.

         11. If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Stockholders shall then be under any
liability to any Underwriter except as provided in Sections 6 and 8 hereof; but,
if for any other reason any Shares are not delivered by or on behalf of the
Company and the Selling Stockholders as provided herein, 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 Shares not so delivered, but the Company and the Selling
Stockholders shall then be under no further liability to any Underwriter in
respect of the Shares not so delivered except as provided in Sections 6 and 8
hereof. 

         12. 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 Goldman, Sachs & Co. on behalf of you as the
Representatives; and in all dealings with any Selling Stockholder hereunder, you
and the Company shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of such Selling Stockholder made or given by any
or all of the Attorneys-in-Fact for such Selling Stockholder. 


                                       21


         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the Representatives in care of Goldman, Sachs &
Co., 85 Broad Street, New York, New York 10004, Attention: Registration
Department; if to any Selling Stockholder shall be delivered or sent by mail,
telex or facsimile transmission to counsel for such Selling Stockholder at its
address set forth in Schedule II hereto; and if to the Company shall be
delivered or sent by mail, telex or facsimile transmission to the address of the
Company set forth in the Registration Statement, Attention: President; provided,
however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall
be delivered or sent by mail, telex or facsimile transmission to such
Underwriter at its address set forth in its Underwriters' Questionnaire or telex
constituting such Questionnaire, which address will be supplied to the Company
or the Selling Stockholders by you on request. Any such statements, requests,
notices or agreements shall take effect upon receipt thereof.

         13. This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company and the Selling Stockholders and, to
the extent provided in Sections 8 and 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 Shares from any
Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

         14. Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

         15. This Agreement shall be governed by and construed in accordance
with the laws of the State of New York.

         16. This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

         If the foregoing is in accordance with your understanding, please sign
and return to us one for the Company and each of the Representatives plus one
for each counsel and the Custodian, if any counterparts hereof, and upon the
acceptance hereof by you, on behalf of each of the Underwriters, this letter and
such acceptance hereof shall constitute a binding agreement among each of the
Underwriters, the Company and each of the Selling Stockholders. It is understood
that your acceptance of this letter on behalf of each of the Underwriters is
pursuant to the authority set forth in a form of Agreement among Underwriters,
the form of which shall be submitted to the Company and the Selling Stockholders
for examination, upon request, but without warranty on your part as to the
authority of the signers thereof.


                                       22


         Any person executing and delivering this Agreement as Attorney-in-Fact
for a Selling Stockholder represents by so doing that he has been duly appointed
as Attorney-in-Fact by such Selling Stockholder pursuant to a validly existing
and binding Power-of-Attorney which authorizes such Attorney-in-Fact to take
such action.

         Pursuant to Section 7(e) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

                  (i) They are independent certified public accountants with
respect to the Company and its subsidiaries within the meaning of the Securities
Act of 1933, as amended (the "Act") and the applicable published rules and
regulations thereunder;

                  (ii)In their opinion, the financial statements and any
supplementary financial information and schedules (and, if applicable, financial
forecasts and/or pro forma financial information) examined by them and included
in the Prospectus or the Registration Statement comply as to form in all
material respects with the applicable accounting requirements of the Act and the
related published rules and regulations thereunder; and, if applicable, they
have made a review in accordance with standards established by the American
Institute of Certified Public Accountants of the unaudited consolidated interim
financial statements, selected financial data, pro forma financial information,
financial forecasts and/or condensed financial statements derived from audited
financial statements of the Company for the periods specified in such letter, as
indicated in their reports thereon, copies of which have been separately
furnished to the representatives of the Underwriters (the "Representatives") and
are attached hereto; 

                  (iii) The unaudited selected financial information with
respect to the consolidated results of operations and financial position of the
Company for the five most recent fiscal years included in the Prospectus agrees
with the corresponding amounts (after restatements where applicable) in the
audited consolidated financial statements for such five fiscal years;

                  (iv) They have compared the information in the Prospectus
under selected captions with the disclosure requirements of Regulation S-K and
on the basis of limited procedures specified in such letter nothing came to
their attention as a result of the foregoing procedures that caused them to
believe that this information does not conform in all material respects with the
disclosure requirements of Items 301, 302, 402 and 503(d), respectively, of
Regulation S-K;

                  (v) On the basis of limited procedures, not constituting an
examination in accordance with generally accepted auditing standards, consisting
of a reading of the unaudited financial statements and other information
referred to below, a reading of the latest available interim financial
statements of the Company and its subsidiaries, inspection of the minute books
of the Company and its subsidiaries since the date of the latest audited
financial statements included in the Prospectus, inquiries of officials of the
Company and its subsidiaries responsible for financial and accounting matters
and such other inquiries and 

                                       1



procedures as may be specified in such letter,
nothing came to their attention that caused them to believe that:

                  (A) (i) the unaudited consolidated statements of income,
consolidated balance sheets and consolidated statements of cash flows included
in the Prospectus do not comply as to form in all material respects with the
applicable accounting requirements of the Act and the related published rules
and regulations, or (ii) any material modifications should be made to the
unaudited condensed consolidated statements of income, consolidated balance
sheets and consolidated statements of cash flows included in the Prospectus for
them to be in conformity with generally accepted accounting principles;

                  (B) any other unaudited income statement data and balance
sheet items included in the Prospectus do not agree with the corresponding items
in the unaudited consolidated financial statements from which such data and
items were derived, and any such unaudited data and items were not determined on
a basis substantially consistent with the basis for the corresponding amounts in
