Gentlemen:

    Central Garden & Pet Company, a Delaware corporation (the ``Company'')

Schedule I hereto for whom you are acting as representatives (the
``Representatives'') an aggregate of 2,750,000 shares of the Company's Common

will be sold by certain stockholders of the Company (the "Selling Stockholders")
named in Schedule II hereto (the "Firm Selling Stockholder Shares"). The
respective amounts of the Firm Shares to be so purchased by the several

Company also proposes to sell at the Underwriters' option an aggregate of up to
412,500 additional shares of the Company's Common Stock (the ``Option Shares'')
as set forth below.

    As the Representatives, you have advised the Company and the Selling
Stockholders (a) that you are authorized to enter into this Agreement on behalf
of the several Underwriters, and (b) that the several Underwriters are willing,
acting severally and not jointly, to purchase the numbers of Firm Shares set

respective names in Schedule I, plus their pro rata portion of the Option Shares
if you elect to exercise the Over-allotment option in whole or in part for the
accounts of the several Underwriters. The Firm Shares and the Option Shares (to
the extent the aforementioned option is exercised) are herein collectively
called the ``Shares.''

    In consideration of the mutual agreements contained herein and of the
interests of the parties in the transactions contemplated hereby, the parties
hereto agree as follows:

    1.    (a)  Representations and Warranties of the Company and the Selling
               -------------------------------------------------------------
Stockholders.  The Company and the Selling Stockholders, jointly and severally,

represent and warrant to each  of the Underwriters as follows:

         (i)    A registration statement on Form S-3 (File No. 333-     ) with
respect to the Shares has been carefully prepared by the Company in conformity
with the requirements of the Securities Act of 1933, as amended (the ``Act''),
and the Rules and Regulations (the ``Rules and Regulations'') of the Securities
and Exchange Commission (the ``Commission'') thereunder and has been filed with
the Commission.   The Company meets all of the requirements for filing on Form
S-3.  Copies of such registration statement, including any amendments thereto,
the preliminary prospectuses (meeting the requirements of the Rules and
Regulations) contained therein and the exhibits, financial statements and
schedules, as finally amended and revised, have heretofore been delivered by the
Company to you.  Such registration statement, together with any registration
statement filed by the Company pursuant to Rule 462(b) of the Act, herein
referred to as the ``Registration Statement,'' which shall be deemed to include
all information omitted therefrom in reliance upon Rule 430A and contained in
the Prospectus referred to below, has become effective under the Act and no
post-effective amendment to the Registration Statement has been filed as of the
date of this Agreement.  ``Prospectus'' means (a) the form of prospectus first
filed with the Commission pursuant to Rule 424(b) or (b) the last preliminary
prospectus included in the Registration Statement filed prior to the time it
becomes effective or filed pursuant to Rule 424(a) under the Act that is
delivered by the Company to the Underwriters for delivery to purchasers of the
Shares, together with the term sheet or abbreviated term sheet filed with the
Commission pursuant to Rule 424(b)(7) under the Act.  Each preliminary
prospectus included in the Registration Statement prior to the time it becomes
effective is herein referred to as a ``Preliminary Prospectus.''  Any reference
herein to the Registration Statement, any Preliminary Prospectus or the
Prospectus, as the case may be, shall be deemed to refer to and include the
documents incorporated by reference therein pursuant to Item 12 of Form S-3
which were filed under the Securities Exchange Act of 1934, as amended (the
"Exchange Act").

         (ii)   The Company has been duly organized and is validly existing as a
corporation in good standing under the laws of the State of Delaware, with
corporate power and corporate authority to own or lease its properties and
conduct its business as described in the Registration Statement.  Each of the

Report on Form 10-K for the fiscal year ended September 30, 1995 (collectively,
the ``Subsidiaries'') has been duly organized and is validly existing as a
corporation in good standing under the laws of the jurisdiction of its
incorporation, with corporate power and corporate authority to own or lease its
properties and conduct its business as described in the Registration Statement.
The Subsidiaries are the only subsidiaries, direct or indirect, of the Company.
The Company and each of the Subsidiaries are duly qualified to transact business
in all jurisdictions in which the conduct of their business requires such
qualification, except where such failure would not have a material adverse
effect on the Company and its Subsidiaries taken as a whole.  The outstanding
shares of capital stock of each of the Subsidiaries have been duly authorized
and validly issued, are fully paid and non-assessable and are owned by the
Company or another Subsidiary free and clear of all liens, encumbrances and
equities and claims; and no options, warrants or other rights to purchase,
agreements or other obligations to issue or other rights to convert any
obligations into shares of capital stock or ownership interests in the
Subsidiaries are outstanding.

         (iii)  The outstanding shares of Common Stock of the Company have been
duly authorized and validly issued and are fully paid and non-assessable; the
Shares to be issued and sold by the Company have been duly authorized and when
issued and paid for as contemplated herein will be validly issued, fully paid
and non-assessable; and no preemptive rights of stockholders exist with respect
to any of the Shares or the issue and sale thereof.  Neither the filing of the
Registration Statement nor the offering or sale of the Shares as contemplated by
this Agreement gives rise to any rights, other than those which have been waived
or satisfied, for or relating to the registration of any shares of Common Stock.

         (iv)   The information set forth under the caption ``Capitalization''
 in the Prospectus is true and correct. All of the Shares conform to the
description thereof contained in the Registration Statement. The form of
certificates for the Shares conforms to the corporate law of the jurisdiction of
the Company's incorporation.

         (v)    The Commission has not issued an order preventing or suspending
the use of any Prospectus relating to the proposed offering of the Shares nor
instituted proceedings for that purpose.  The Registration Statement contains,

material statements which are required to be stated therein by, and will in all
material respects conform, to the requirements of the Act and the Rules and
Regulations.  The Registration Statement and any amendment hereto do not
contain, and will not contain, any untrue statement of a material fact and do
not omit, and will not omit, to state any 

                                      3.

 
material fact required to be stated therein or necessary to make the statements
therein not misleading. The Prospectus and any amendments and supplements
thereto do not contain, and will not contain, any untrue statement of material
fact; and do not omit, and will not omit, to state any material fact required to
be stated therein or necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading; provided, however,
that the Company makes no representations or warranties as to information
contained in or omitted from 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 or on behalf of any Underwriter
through the Representatives, specifically for use in the preparation thereof.
The documents incorporated by reference in the Registration Statement, any
Preliminary Prospectus and the Prospectus, when they were filed with the
Commission, conformed in all material respects to the requirements of the
Exchange Act and the rules and regulations of the Commission thereunder, and
none of such documents contained any 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.

Subsidiaries, together with related notes and schedules as set forth in the

used therein are appropriate to give effect to the transactions or circumstances
referred to therein. No other financial statements or schedules of the Company
or any other entity are required to be included, in or incorporated into the
Registration Statement pursuant to any requirement of the Act or any Rules and
Regulations, including Rule 3-05 of Regulation S-X.

    (b)  Payment for the Firm Shares to be sold hereunder is to be made (i)

Shares are priced, as contemplated by Rule 15c6-1(c) of the Securities Exchange

time, the fourth) business day after the date of this Agreement or at such other
time and date not later than five business days thereafter as you and the
Company shall agree upon, such time and date being herein referred to as the
``Closing Date.'' (As used herein, ``business day'' means a day on which the New
York Stock Exchange is open for trading and on which banks in New York are open
for business and are not permitted by law or executive order to be closed.) The
certificates for the Firm Shares will be delivered in such denominations and in
such registrations as the Representatives request in writing not later than the

                                      9.

for inspection by the Representatives at least one business day prior to the
Closing Date.
 
    (c)  In addition, on the basis of the representations and warranties herein
contained and subject to the terms and conditions herein set forth, the Company
hereby grants an option to the several Underwriters to purchase the Option
Shares at the price per share as set forth in the first paragraph of this
Section 2. The option granted hereby may be exercised in whole or in part by
giving written notice (i) at any time before the Closing Date and (ii) only once
thereafter within 30 days after the date of this Agreement, by you, as
Representatives of the several Underwriters, to the Company setting forth the
number of Option Shares as to which the several Underwriters are exercising the
option, the names and denominations in which the Option Shares are to be
registered and the time and date at which such certificates are to be delivered.
The time and date at which certificates for Option Shares are to be delivered
shall be determined by the Representatives but shall not be earlier than three
nor later than 10 full business days after the exercise of such option, nor in
any event prior to the Closing Date (such time and date being herein referred to
as the ``Option Closing Date''). If the date of exercise of the option is three
or more days before the Closing Date, the notice of exercise shall set the
Closing Date as the Option Closing Date. The number of Option Shares to be
purchased by each Underwriter shall be in the same proportion to the total
number of Option Shares being purchased as the number of Firm Shares being
purchased by such Underwriter bears to 5,000,000, adjusted by you in such manner
as to avoid fractional shares. The option with respect to the Option Shares
granted hereunder may be exercised only to cover over-allotments in the sale of
the Firm Shares by the Underwriters. You, as Representatives of the several
Underwriters, may cancel such option at any time prior to its expiration by
giving written notice of such cancellation to the Company. To the extent, if
any, that the option is exercised, payment for the Option Shares shall be made
on the Option Closing Date in New York Clearing House funds by certified or bank
cashier's check drawn to the order of the Company against delivery of
certificates therefor at the offices of Alex. Brown & Sons Incorporated, 135
East Baltimore Street, Baltimore, Maryland.

3.  Offering by the Underwriters.
    -----------------------------

    It is understood that the several Underwriters are to make a public
offering of the Firm Shares as soon as the Representatives deem it advisable to
do so.  The Firm Shares are to be initially offered to the public at the initial
public offering price set forth in the Prospectus.  The Representatives may from
time to time thereafter change the public offering price and other selling
terms.  To the extent, if at all, that any Option Shares are purchased pursuant
to Section 2 hereof, the Underwriters will offer them to the public on the
foregoing terms.

                                      10.

 
    It is further understood that you will act as the Representatives for the

supplement to the Prospectus or for any additional information, and (D) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the use of the Prospectus or of the institution of any
proceedings for that purpose. The Company will use its best efforts to prevent
the issuance of any such stop order preventing or suspending the use of the
Prospectus and to obtain as soon as possible the lifting thereof, if issued.

         (iii)  The Company will cooperate with the Representatives in
endeavoring to qualify the Shares for sale under the securities laws of such
jurisdictions as the Representatives may reasonably have designated in writing
and will make such applications, file such documents, and furnish such
information as may be reasonably required for that purpose, provided the Company
shall not be required to qualify as a foreign corporation or to file a general
consent to service of process in any jurisdiction where it is not now so
qualified or required to file such a consent.  The Company will, from time to
time, prepare and file such statements, reports, and other documents, as are or
may be required to continue 

                                      11.

 
such qualifications in effect for so long a period as the Representatives may
reasonably request for distribution of the Shares.

         (iv)   The Company will deliver to, or upon the order of, the
Representatives, from time to time, as many copies of any Preliminary Prospectus
as the Representatives may reasonably request.  The Company will deliver to, or
upon the order of, the Representatives during the period when delivery of a
Prospectus is required under the Act, as many copies of the Prospectus in final
form, or as thereafter amended or supplemented, as the Representatives may
reasonably request.  The Company will deliver to the Representatives at or
before the Closing Date, four signed copies of the Registration Statement and
all amendments thereto including all exhibits filed therewith, and will deliver
to the Representatives such number of copies of the Registration Statement
(including such number of copies of the exhibits filed therewith that may
reasonably be requested), and of all amendments thereto, as the Representatives
may reasonably request.

         (v)    The Company will comply with the Act and the Rules and
Regulations, and the Exchange Act, and the rules and regulations of the
Commission thereunder, so as to permit the completion of the distribution of the
Shares as contemplated in this Agreement and the Prospectus.  If during the
period in which a prospectus is required by law to be delivered by an
Underwriter or dealer, any event shall occur as a result of which, in the
judgment of the Company or the reasonable opinion of the Underwriters, it
becomes necessary to amend or supplement the Prospectus in order to make the
statements therein, in the light of the circumstances existing at the time the
Prospectus is delivered to a purchaser, not misleading, or, if it is necessary
at any time to amend or supplement the Prospectus to comply with any law, the
Company promptly will prepare and file with the Commission an appropriate
amendment to the Registration Statement or supplement to the Prospectus so that
the Prospectus as so amended or supplemented will not, in the light of the
circumstances when it is so delivered, be misleading, or so that the Prospectus
will comply with the law.

         (vi)   The Company will make generally available to its security
holders, as soon as it is practicable to do so, but in any event not later than
15 months after the effective date of the Registration Statement, an earning
statement (which need not be audited) in reasonable detail, covering a period of
at least 12 consecutive months beginning after the effective date of the
Registration Statement, which earning statement shall satisfy the requirements
of Section 11(a) of the Act and Rule 158 of the Rules and Regulations and will
advise you in writing when such statement has been so made available.

         (vii)  The Company will, for a period of five years from the Closing
Date, deliver to the Representatives copies of annual reports and copies of all
other documents, reports and information furnished by the Company to its
stockholders or filed with any securities exchange pursuant to the requirements
of such exchange or with the Commission pursuant to the Act or the Exchange Act.

                                      12.

 
The Company will deliver to the Representatives similar reports with respect to
significant subsidiaries, as that term is defined in the Rules and Regulations,
which are not consolidated in the Company's financial statements.

         (viii) No offering, sale, short sale or other disposition of any
shares of Common Stock of the Company or other securities convertible into or
exchangeable or exercisable for shares of Common Stock or derivative of Common
Stock (or agreement for such) will be made for a period of 120 days after the
date of this Agreement, directly or indirectly, by the Company otherwise than
hereunder or with the prior written consent of Alex. Brown & Sons Incorporated.
The foregoing sentence shall not apply to (A) options to purchase Common Stock
granted or Common Stock issued under the Company's presently authorized stock
option plans and equity incentive plans described in the Prospectus, (B) Common
Stock issued upon exercise of the Warrant held by Monsanto Company as described
in the Prospectus, and (C) Common Stock issued upon conversion of the Series A
Preferred Stock held by Monsanto Company as described in the Prospectus.

         (ix)   The Company will use its best efforts to list, subject to notice
of issuance, the Shares on the Nasdaq National Market.

         (x)    The Company has caused each officer, director and stockholder of
the Company identified by the Representatives to furnish to you, on or prior to
the date of this agreement, a letter or letters, in form and substance
satisfactory to the Underwriters, pursuant to which each such person shall agree
not to offer, sell, sell short or otherwise dispose of any shares of Common
Stock of the Company or other capital stock of the Company, or any other
securities convertible, exchangeable or exercisable for Common Shares or
derivative of Common Shares owned by such person or request the registration for
the offer or sale of any of the foregoing (or as to which such person has the
right to direct the disposition of) for a period of 120 days after the date of
this Agreement, directly or indirectly, except with the prior written consent of
Alex. Brown & Sons Incorporated (``Lockup Agreements'').

         (xi)   The Company shall apply the net proceeds of its sale of the
Shares as set forth in the Prospectus.

         (xii)  The Company shall not invest, or otherwise use the proceeds
received by the Company from its sale of the Shares in such a manner as would
require the Company or any of the Subsidiaries to register as an investment
company under the Investment Company Act of 1940, as amended (the ``1940 Act'').

         (xiii) The Company will maintain a transfer agent and, if necessary
under the jurisdiction of incorporation of the Company, a registrar for the
Common Stock.

                                      13.

 
         (xiv)  The Company will not take, directly or indirectly, any action
designed to cause or result in, or that has constituted or might reasonably be
expected to constitute, the stabilization or manipulation of the price of any
securities of the Company.

5.  Costs and Expenses.
    -------------------

    Whether or not the transactions contemplated hereunder are consummated or
this Agreement becomes effective or is terminated, the Company will pay and
unless otherwise paid by the Company, the Selling Stockholders agree to pay, in
such proportions as they may agree among themselves all costs, expenses and fees
incident to the performance of the obligations of the Company under this
Agreement, including, without limiting the generality of the foregoing, the

and sale of directed shares of the Common Stock by the Underwriters to employees
and persons having business relationships with the Company and its Subsidiaries.

Selling Stockholders.

Representatives and complied with to their reasonable satisfaction. No stop
order suspending the effectiveness of the Registration Statement, as amended

     business, operations or financial condition of the Company.

         (iii)  The outstanding shares of capital stock of the Company and the

         (v)    The Underwriting Agreement has been duly authorized by all

     need express no opinion), when they were filed with the Commission,
     complied as to form in all material respects with the requirements of the
     Exchange Act and the rules and regulations of the Commission thereunder.

         (xi)   The execution and delivery by the Company of, and performance by

     against or affecting the Company which would require disclosure in the
     Prospectus.

         (xiii) To the best of such counsel's knowledge, except as set forth

     the best of such counsel's knowledge, the performance of this Agreement and
     the Stockholders' Agreement and the consummation of the transactions herein
     contemplated by each Selling Stockholder will not result in a breach of, or
     constitute a default under, any material indenture, mortgage, deed of
     trust, trust (constructive or other), loan agreement, lease, franchise,
     license or other material agreement or instrument to which each Selling
     Stockholder is a party or by which each Selling Stockholder or any of his

         (xvi)  To the best of such counsel's knowledge, each Selling

     Agreement and the Stockholders' Agreement and to sell, transfer and deliver
     the Common Shares to be sold on such Closing Date by each Selling
     Stockholder hereunder and good and marketable title to such Shares so sold,
     free and clear of all liens encumbrances, equities, claims, restrictions,
     security interests, voting trusts, or other defects of title whatsoever,
     has been transferred to the Underwriters (whom counsel may assume to be
     bona fide purchasers) who have purchased such Shares hereunder; and

                                      17.

 
         (xvii) To the best of such counsel's knowledge, the Stockholders'
     Agreement are valid and binding agreements of each Selling Stockholder,
     enforceable in accordance with their terms except as enforceability may be

     reorganization, moratorium or other laws affecting creditors' rights
     generally.

         In rendering such opinion, such counsel may rely as to matters of

case their opinion is to state that they are so doing and that the Underwriters
are justified in relying on such opinions or certificates and copies of said
opinions or certificates are to be attached to the opinion or delivered at the
Closing.  Such counsel shall also include statements to the effect that (1) such
counsel believes that, as of the effective date of the Registration Statement,
the Registration Statement and the Prospectus complied as to form in all
material respects with the requirements of the 1933 Act; and (2) nothing has
come to such counsel's attention that would lead such counsel to believe that
either at the effective date of the Registration Statement or at the applicable
Closing Date the Registration Statement or the Prospectus, or any such amendment
or supplement, contains any untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except that such counsel need not express such an opinion as to
the financial statements, schedules and financial data contained in the
Registration Statement or the Prospectus.

    (c)  The Representatives shall have received on the Closing Date or the
Option Closing Date, as the case may be, the opinion of Knox Ricksen, counsel
for the Company and its Subsidiaries, dated the Closing Date or the Option

that it may be relied upon by counsel to the Underwriters) to the effect that:

         (i)    Each of the Subsidiaries of the Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
California.

         (ii)   Each of the Subsidiaries of the Company has the full corporate
power and corporate authority to own, lease and operate its business as
described in the Prospectus; and each of the Subsidiaries of the Company is duly
qualified to do business as a foreign corporation and is in good standing in all
jurisdictions in the United States in which such subsidiary is required to be
qualified and in which the failure so to qualify taken in the aggregate would
have a material adverse effect on the business, operations or financial
condition of the Company.

         (iii)  The outstanding shares of capital stock of each of the
Subsidiaries of the Company have been duly and validly authorized and issued 

                                      18.

 
and are fully paid and nonassessable and free of preemptive rights and issued in
compliance with all federal securities laws.

    (d)  The Representatives shall have received from Brobeck, Phleger &
Harrison LLP, counsel for the Underwriters, an opinion dated the Closing Date or
the Option Closing Date, as the case may be, substantially to the effect
specified in subparagraphs (iv), (v) and (vi) of subparagraph (b) of this
Section 6, and that the Company is a duly organized and validly existing
corporation under the laws of the State of Delaware.  In rendering such opinion
Brobeck, Phleger & Harrison LLP may rely as to all matters governed other than
by the laws of the State of California or Federal laws on the opinion of counsel
referred to in Paragraph (b) of this Section 6.  In addition to the matters set
forth above, such opinion shall also include a statement to the effect that
nothing has come to the attention of such counsel which leads them to believe
that (i) the Registration Statement, or any amendment thereto, as of the time it
became effective under the Act (but after giving effect to any modifications
incorporated therein pursuant to Rule 430A under the Act) as of the Closing Date
or the Option Closing Date, as the case may be, 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, and (ii) the
Prospectus, or any supplement thereto, on the date it was filed pursuant to the
Rules and Regulations and as of the Closing Date or the Option Closing Date, as
the case may be, contained an untrue statement of a material fact or omitted to
state a material fact necessary in order to make the statements, in the light of
the circumstances under which they are made, not misleading (except that such
counsel need express no view as to financial statements, schedules and
statistical information therein).  With respect to such statement, Brobeck,
Phleger & Harrison LLP may state that their belief is based upon the procedures
set forth therein, but is without independent check and verification.

    (e)  The Representatives shall have received at or prior to the Closing Date
from Brobeck, Phleger & Harrison LLP a memorandum or summary, in form and
substance satisfactory to the Representatives, with respect to the qualification
for offering and sale by the Underwriters of the Shares under the State
securities or Blue Sky laws of such jurisdictions as the Representatives may

respects with the applicable accounting requirements of the Act and the related
published Rules and Regulations; and containing such other statements and

     which should have been set forth in a supplement to or an amendment of the
     Prospectus which has not been so set forth in such supplement or amendment;

                                      20.

obligation to each other (except to the extent provided in Sections 5 and 8
hereof).

7.  Conditions of the Obligations of the Company.
    ---------------------------------------------

    The obligations of the Company to sell and deliver the portion of the
Shares required to be delivered as and when specified in this Agreement are
subject to the conditions that at the Closing Date or the Option Closing Date,
as the case may be, no stop order suspending the effectiveness of the
Registration Statement shall have been issued and in effect or proceedings
therefor initiated or threatened.

8.  Indemnification.
    ----------------

    (a)  The Company and the Selling Stockholders, jointly and severally, agree
to indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of the Act, against any losses,
claims, damages or liabilities to which such Underwriter or such controlling
person may become subject under the Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement, any
Preliminary Prospectus, the Prospectus or any amendment or supplement thereto,
(ii) any inaccuracy in the representations and warranties of the Company or the
Selling Stockholders contained herein or any failure of the Company or the
Selling Stockholders to perform its obligations hereunder or under law, or (iii)
the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading; and
will reimburse each Underwriter and each such controlling person for any legal
or other expenses reasonably incurred by such Underwriter or such controlling
person in connection with investigating or defending any such loss, claim,
damage, liability, action or proceeding or in responding to a subpoena or
governmental inquiry related to the offering of the Shares, whether or not such
Underwriter or controlling person is a party to any action or proceeding;
provided, however, that neither the Company nor the Selling Stockholders will 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 made in the Registration Statement,
any Preliminary Prospectus, the Prospectus, or such amendment or supplement, in
reliance upon and in conformity with written information furnished to the
Company by or through the Representatives specifically for use in the
preparation thereof.  The Underwriters acknowledge that the Company and the
Selling Stockholders intend to agree, as among themselves and without limiting
the rights of the Underwriters under this 

                                      22.

 
Agreement, as to their respective amounts of such liability for which they each
shall be responsible. This indemnity agreement will be in addition to any
liability which the Company or the Selling Stockholders may otherwise have.

    (b)  Each Underwriter severally and not jointly will indemnify and hold
harmless the Company, each of its directors, each of its officers who have
signed the Registration Statement, each person, if any, who controls the Company
within the meaning of the Act and the Selling Stockholders, against any losses,
claims, damages or liabilities to which the Company, the Selling Stockholders or
any such director, officer, or controlling person may become subject under the
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions or proceedings in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement, any Preliminary Prospectus, the Prospectus or any
amendment or supplement thereto, or (ii) the omission or the alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading in the light of the circumstances under
which they were made; and will reimburse any legal or other expenses reasonably
incurred by the Company, the Selling Stockholders or any such director, officer,
or controlling person in connection with investigating or defending any such
loss, claim, damage, liability, action or proceeding; provided, however, that
each Underwriter will be liable in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission has been made in the Registration Statement, any Preliminary
Prospectus, the Prospectus or such amendment or supplement, in reliance upon and
in conformity with written information furnished to the Company by or through
the Representatives specifically for use in the preparation thereof.  This
indemnity agreement will be in addition to any liability which such Underwriter
may otherwise have.

    (c)  In case any proceeding (including any governmental investigation) shall
be instituted involving any person in respect of which indemnity may be sought
pursuant to this Section 8, such person (the ``indemnified party'') shall
promptly notify the person against whom such indemnity may be sought (the
``indemnifying party'') in writing.  No indemnification provided for in Section
8(a) or (b) shall be available to any party who shall fail to give notice as
provided in this Section 8(c) if the party to whom notice was not given was
unaware of the proceeding to which such notice would have related and was
materially prejudiced by the failure to give such notice, but the failure to
give such notice shall not relieve the indemnifying party or parties from any
liability which it or they may have to the indemnified party for contribution or
otherwise than on account of the provisions of Section 8(a) or (b).  In case any
such proceeding 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
shall pay as incurred the fees and disbursements of 

                                      23.

 
such counsel related to such proceeding. In any such proceeding, any indemnified
party shall have the right to retain its own counsel at its own expense.
Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or
within 30 days of presentation) the fees and expenses of the counsel retained by
the indemnified party in the event (i) the indemnifying party and the
indemnified party shall have mutually agreed to the retention of such counsel or
(ii) the named parties to any such proceeding (including any impleaded parties)
include both the indemnifying party and the indemnified party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them or (iii) the indemnifying party shall
have failed to assume the defense and employ counsel acceptable to the
indemnified party within a reasonable period of time after notice of
commencement of the action. It is understood that the indemnifying party shall
not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate firm for all such indemnified parties. Such firm shall be designated in
writing by you in the case of parties indemnified pursuant to Section 8(a) and
by the Company in the case of parties indemnified pursuant to Section 8(b). The
indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent but if settled with such consent or if
there be a final judgement for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment. In addition, the indemnifying party will not,
without the prior written consent of the indemnified party, settle or compromise
or consent to the entry of any judgment in any pending or threatened claim,
action or proceeding of which indemnification may be sought hereunder (whether
or not any indemnified party is an actual or potential party to such claim,
action or proceeding) unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising out
of such claim, action or proceeding.

    (d)  If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under Section 8(a) or (b)
above in respect of any losses, claims, damages or liabilities (or actions or
proceedings 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 or
proceedings in respect thereof) in such proportion as is appropriate to reflect
the relative benefits received by the Company 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 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 or proceedings in respect
thereof), as well as any other relevant equitable considerations.  The relative
benefits received by the Company 

                                      24.

 
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 and 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, the Selling Stockholders and the Underwriters agree that it
would not be just and equitable if contributions pursuant to this Section 8(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 Section
8(d).  The amount paid or payable by an indemnified party as a result of the
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) referred to above in this Section 8(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), (i) no Underwriter shall
be required to contribute any amount in excess of the underwriting discounts and
commissions applicable to the Shares purchased by such Underwriter, and (ii) 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 Section 8(d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

    (e)  In any proceeding relating to the Registration Statement, any
Preliminary Prospectus, the Prospectus or any supplement or amendment thereto,
each party against whom contribution may be sought under this Section 8 hereby
consents to the jurisdiction of any court already having jurisdiction over the
Company or any Selling Stockholders.

    (f)  Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 8 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred.  The
indemnity and contribution agreements contained in this Section 8 and the
representations and warranties of the Company and the Selling Stockholders set
forth in this Agreement shall remain operative and in full force and effect,
regardless of (i) any investigation made by or on behalf of any Underwriter or
any person controlling any Underwriter, the Company, its directors or officers
or any persons controlling the Company or any Selling Stockholders, (ii)
acceptance of any 

                                      25.

 
Shares and payment therefor hereunder, and (iii) any termination of this
Agreement. A successor to any Underwriter, to the Company, its directors or
officers, or any person controlling the Company or any Selling Stockholders,
shall be entitled to the benefits of the indemnity, contribution and
reimbursement agreements contained in this Section 8.

9.  Default by Underwriters.
    ------------------------

    If on the Closing Date or the Option Closing Date, as the case may be, any
Underwriter shall fail to purchase and pay for the portion of the Shares which
such Underwriter has agreed to purchase and pay for on such date (otherwise than
by reason of any default on the part of the Company, the Selling Stockholders,
you, as Representatives of the Underwriters, shall use your reasonable efforts
to procure within 36 hours thereafter one or more of the other Underwriters, or
any others, to purchase from the Company or the Selling Stockholders such
amounts as may be agreed upon and upon the terms set forth herein, the Firm
Shares or Option Shares, as the case may be, which the defaulting Underwriter or
Underwriters failed to purchase.  If during such 36 hours you, as such
Representatives, shall not have procured such other Underwriters, or any others,
to purchase the Firm Shares or Option Shares, as the case may be, agreed to be
purchased by the defaulting Underwriter or Underwriters, then (a) if the
aggregate number of shares with respect to which such default shall occur does
not exceed 10% of the Firm Shares or Option Shares, as the case may be, covered
hereby, the other Underwriters shall be obligated, severally, in proportion to
the respective numbers of Firm Shares or Option Shares, as the case may be,
which they are obligated to purchase hereunder, to purchase the firm Shares or
Option Shares, as the case may be, which such defaulting Underwriter or
Underwriters failed to purchase, or (b) if the aggregate number of shares of
Firm Shares or Option Shares, as the case may be, with respect to which such
default shall occur exceeds 10% of the Firm Shares or Option Shares, as the case
may be, covered hereby, the Company, the Selling Stockholders or you as the
Representatives of the Underwriters will have the right, by written notice given
within the next 36-hour period to the parties to this Agreement, to terminate
this Agreement without liability on the part of the non-defaulting Underwriters
or of the Company except to the extent provided in Section 8 hereof.  In the
event of a default by any Underwriter or Underwriters, as set forth in this
Section 9, the Closing Date or Option Closing Date, as the case may be, may be
postponed for such period, not exceeding seven days, as you, as Representatives,
may determine in order that the required changes in the Registration Statement
or in the Prospectus or in any other documents or arrangements may be effected.
The term ``Underwriter'' includes any person substituted for a defaulting
Underwriter.  Any action taken under this Section 9 shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

                                      26.

    Without limiting the right to terminate this Agreement pursuant to any other
provision hereof:

    (a)  This Agreement may be terminated by the Company by notice to you or 
by you by notice to the Company at any time prior to the earlier of (i) the time
the Shares are released by you for sale by notice to the Underwriters, or (ii)
11:30 a.m. on the first business day following the date of this Agreement;

as a whole, whether or not arising in the ordinary course of business, (ii) any
outbreak or escalation of hostilities or declaration of war or national
emergency or other national or international calamity or crisis or change in

suspension of trading in securities generally on the New York Stock Exchange or
the American Stock Exchange or limitation on prices (other than limitations on
hours or numbers of days of trading) for securities on either such Exchange,

State authorities, (vi) the suspension of trading of the Company's common stock
by the Commission on the Nasdaq National Market or (vii) the taking of any
action by any government body or agency in respect of its monetary or fiscal
affairs which in your reasonable opinion has a material adverse effect on the
securities markets in the United States; or

    (c)  as provided in Sections 6 and 9 of this Agreement.

12. Failure of the Selling Stockholder to Sell and Deliver.
    --------------------------------------------------------

    If any of the Selling Stockholders shall fail to sell and deliver to the
Underwriters the Shares to be sold and delivered by such Selling Stockholder at
the Closing Date under the terms of this Agreement, then the Underwriters may,
at their option, by written notice from you to the Company and the Selling
Stockholders, either (i) terminate this Agreement without any liability on the
part of any Underwriter or, except as provided in Sections 5 and 8 hereof, the
Company or the Selling Stockholders, or (ii) purchase the shares which the
Company has agreed to sell and deliver in accordance with the terms hereof.  In
the event of a failure by the Selling Stockholders to sell and deliver as
referred to in this Section, either you or the Company shall have the right to
postpone the Closing Date for a period not exceeding seven business days in
order that the necessary changes in the Registration Statement, Prospectus and
any other documents, as well as any other arrangements, may be effected.

13. Successors.
    -----------

    This Agreement has been and is made solely for the benefit of the 
Underwriters and the Company and their respective successors, executors,
administrators, heirs and assigns, and the officers, directors and controlling
persons referred to herein, and no other person will have any right or
obligation hereunder. No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign merely because of such purchase.


14. Information Provided by Underwriters.
    -------------------------------------

    The Company and the Underwriters acknowledge and agree that the only 
information furnished or to be furnished by any Underwriter to the Company for
inclusion in any Prospectus or the Registration Statement consists of the
information set forth in the last paragraph on the front cover page (insofar as
such information relates to the Underwriters), legends required by Item 502(d)
of Regulation S-K under the Act and the information under the caption
``Underwriting'' in the Prospectus.

                                      28.

 
15. Miscellaneous.
    --------------

    The reimbursement, indemnification and contribution agreements contained 
in this Agreement and the representations, warranties and covenants in this
Agreement shall remain in full force and effect regardless of (a) any
termination of this Agreement, (b) any investigation made by or on behalf of any
Underwriter or controlling person thereof, or by or on behalf of the Company or
its directors or officers and (c) delivery of and payment for the Shares under
this Agreement.

    This Agreement may be executed in two or more counterparts, each of which 
shall be deemed an original, but all of which together shall constitute one and
the same instrument.

    This Agreement shall be governed by, and construed in accordance with, the 
laws of the State of Maryland.

    Any Person executing and delivering this Agreement as Attorney-in-fact for
any 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. Any action taken under this Agreement by the Attorney-in-fact will
be binding on such Selling Stockholder.
