ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law permits indemnification
by the Company of any director, officer, employee or agent of the Company or
person who is serving or was serving at the Company's request as a director,
officer, employee or agent of another corporation or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him in connection with the
defense of any threatened, pending or completed action (whether civil, criminal,
administrative or investigative), to which he is or may be a party by reason of
having been such director, officer, employee or agent, provided that he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the Company, and, with respect to any criminal action or
proceeding had no reasonable cause to believe his conduct was unlawful. The
Company also has the power under Section 145 to indemnify persons set forth
above from threatened, pending or completed actions or suits by or in the right
of the Company to procure a judgment in its favor by reason of the fact that
such person was a director, officer, employee or agent of the Company or is or
was serving at the request of the Company as a director, officer, employee or
agent of another corporation or enterprise against expenses actually and
reasonably incurred by him in connection with the defense or settlement of the
action if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company, except that no
indemnification can be made with regard to any claim, issue or matter as to
which the person has been adjudged to be liable for negligence or misconduct in
the performance of his duty to the Company unless and only to the extent that
the Delaware Court of Chancery or the court in which the action was brought
determines that the person was fairly and reasonably entitled to indemnity. Any
indemnification (unless ordered by a court) must be made by the Company only as
authorized in the specific case upon a determination that indemnification of the
person is proper in the circumstances because he has met the applicable
standards of conduct. The determination must be made by the Board of Directors
by a majority vote of a quorum consisting of directors who are not parties to
the action, or if a quorum is not obtainable or, even if obtainable, a quorum of
disinterested directors so directs, by independent counsel in a written opinion,
or by the stockholders. The Company may pay the expenses of an action in advance
of final disposition if authorized by the Board of Directors in a specific case,
upon receipt of an undertaking by the person to be indemnified to repay any such
advances unless it shall ultimately be determined that such person is entitled
to be indemnified by the Company as authorized by law.
 
     Article Nine of the Company's By-laws provides for indemnification of the
Company's directors, officers, employees or agents to the extent permitted by
Section 145 of the Delaware General Corporation Law. Article Nine of the
Company's By-laws further provides that the Company may purchase and maintain
 
                                      II-1
<PAGE>   3
 
insurance on behalf of those persons described above as eligible for
indemnification for liability arising out of such person's duties or status with
the Company whether or not indemnification in respect of such liability would be
permissible.
 
     The Company has in effect an officers and directors liability insurance
policy with Royal Insurance Company. The policy provides indemnity to the
directors and officers of the Company for loss arising from any claim by reason
of a wrongful act where there is no corporate indemnification. The insurance
provides for the Company to be reimbursed for any indemnification it may be
required by statute or the Company's By-laws to make to any of its directors and
officers in connection with a claim by reason of a wrongful act. Pursuant to
exclusions, the policy covers negligent acts, errors, omissions or breach of
duty by a director or officer. The principal exclusions from coverage include
the following: (i) claims involving violations of Section 16(b) of the
Securities Exchange Act of 1934; (ii) dishonest acts; and (iii) libel, slander,
or non-monetary damages. The policy has no deductible amount per director or
officer for each loss. A $500,000 deductible self-insurance retention applies to
the Company. The limit of liability under the policy is $5,000,000 in the
aggregate annually in excess of deductibles and participations.

ITEM 17.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of
 
                                      II-2
<PAGE>   4
 
expenses incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
     The undersigned registrant hereby undertakes that:
 
          (1) for purposes of determining any liability under the Act, the
     information omitted from the form of prospectus filed as part of this
     registration statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act shall be deemed to be a part of this registration
     statement as of the time it was declared effective.
 
          (2) for the purpose of determining any liability under the Act, each
     post-effective amendment that contains a form of prospectus shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

certifies that it has reasonable grounds to believe that it meets all the

proposes, subject to the terms and conditions stated herein, to issue and sell
to the Underwriters named in Schedule I (the "Underwriters") an aggregate of
968,700 shares of common stock, par value $0.01 per share ("Common Stock"), of
the Company (the "Company Firm Shares"), and the stockholders of the Company
named in Schedule II hereto (the "Selling Stockholders") propose, subject to the
terms and conditions stated herein, to sell to the Underwriters an aggregate of
31,300 shares of Common Stock in the respective amounts set forth opposite their
names in Schedule II hereto (such shares together with the Company Firm Shares,
the "Firm Shares") and, at the election of the Underwriters, subject to the
terms and conditions stated herein, the Company proposes, subject to the terms
and conditions stated herein, to sell to the Underwriters up to 150,000
additional shares of Common Stock (the "Optional Shares") (the Firm Shares and
the Optional Shares that the Underwriters elect to purchase pursuant to Section
2 hereof are collectively called the "Shares").
 
     1. (a) Representations and Warranties of the Company.  The Company
represents and warrants to, and agrees with, each of the Underwriters that:
 
          (i) A registration statement on Form S-3 (File No. 333-8787) with
     respect to the Shares, including a prospectus subject to completion, has
     been filed by the Company with the Securities and Exchange Commission (the
     "Commission") under the Securities Act of 1933, as amended (the "Act"), and
     one or more amendments to such registration statement may have been so
     filed. After the execution of this Agreement, the Company will file with
     the Commission either (i) if such registration statement, as it may have
     been amended, has become effective under the Act and information has been
     omitted therefrom in accordance with Rule 430A under the Act, either (A) if
     the Company relies on Rule 434 under the Act, a term sheet relating to the
     Shares that shall identify the preliminary prospectus that it supplements
     containing such information as is required or permitted by Rules 434, 430A
     and 424(b) under the Act or (B) if the Company does not rely on Rule 434
     under the Act, a prospectus in the form most recently included in an
     amendment to such registration statement (or, if no such amendment shall
     have been filed, in such registration statement) with such changes or
     insertions as are required by Rule 430A or permitted by Rule 424(b) under
     the Act and as have been provided to and approved by the Representatives,
     or (ii) if such registration statement, as it may have been amended, has
     not become effective under the Act, an amendment to such registration
     statement, including a form of prospectus, a copy of which amendment has
     been provided to and approved by the Representatives prior to the execution
     of this Agreement. The Company may also file a related registration
     statement with the Commission pursuant to Rule 462(b) under the Act for the
     purpose of registering certain additional shares of Common Stock, which
     registration statement will be effective upon filing with the Commission.
     As used in this Agreement, the term "Original Registration Statement" means
     the registration statement
<PAGE>   2
 
     initially filed relating to the Common Stock, as amended at the time when
     it was or is declared effective, including (i) all financial statement
     schedules and exhibits thereto, (ii) all documents incorporated by
     reference therein filed under the Securities Exchange Act of 1934, as
     amended (the "Exchange Act") and (iii) any information omitted therefrom
     pursuant to Rule 430A under the Act and included in the Prospectus (as
     hereinafter defined); the term "Rule 462(b) Registration Statement" means
     any registration statement filed with the Commission pursuant to Rule
     462(b) under the Act (including the Registration Statement and any
     Preliminary Prospectus or Prospectus incorporated therein at the time such
     registration statement becomes effective); the term "Registration
     Statement" includes both the Original Registration Statement and any Rule
     462(b) Registration Statement; the term "Preliminary Prospectus" means each
     prospectus subject to completion included in such registration statement or
     any amendment or post-effective amendment thereto (including the prospectus
     subject to completion, if any, included in the Registration Statement at
     the time it was or is declared effective), including all documents
     incorporated by reference therein filed under the Exchange Act; the term
     "Prospectus" means (A) if the Company relies on Rule 434 of the Act, the
     Term Sheet (as hereinafter defined) relating to the Shares that is first
     filed pursuant to Rule 424(b)(7) of the Act, together with the Preliminary
     Prospectus identified therein that such Term Sheet supplements; (B) if the
     Company does not rely on Rule 434 of the Act, the prospectus first filed
     with the Commission pursuant to Rule 424(b) under the Act or (C) if no
     prospectus is required to be so filed, such term means the prospectus
     included in the Registration Statement, in either case, including all
     documents incorporated by referenced therein filed under the Exchange Act;
     and the term "Term Sheet" means any term sheet that satisfies the
     requirements of Rule 434 of the Act. Any reference in this Agreement to an
     "amendment or supplement" to any Preliminary Prospectus or the Prospectus
     or an "amendment" to any registration statement (including the Registration
     Statement) shall be deemed to include any document incorporated by
     reference therein and filed with the Commission under the Exchange Act
     after the date of such Preliminary Prospectus, Prospectus or Registration
     Statement, as the case may be. For purposes of the preceding sentence, any
     reference to the "effective date" of an amendment to a registration
     statement shall, if such amendment is effected by means of the filing with
     the Commission under the Exchange Act of a document incorporated by
     reference in such registration statement, be deemed to refer to the date on
     which such document was so filed with the Commission and any reference to
     the "date" of a Prospectus that includes a Term Sheet shall mean the date
     of such Term Sheet. As used herein, any reference to any statement or
     information as being "made", "included", "contained", "disclosed", or "set
     forth" in any Preliminary Prospectus, a Prospectus or any amendment or
     supplement thereto, or the Registration Statement or any amendment thereto
     (or other similar references) shall refer both to information and
     statements actually appearing in such document as well as information and
     statements incorporated by reference therein. For purposes of the following
     representations and warranties, to the extent reference is made to the
     Prospectus and at the relevant time the Prospectus is not yet in existence,
     such reference shall be deemed to be to the most recent Preliminary
     Prospectus.
 
          (ii) No order preventing or suspending the use of any Preliminary
     Prospectus has been issued and no proceeding for that purpose has been
     instituted or threatened by the Commission or the securities authority of
     any state or other jurisdiction. If the Registration Statement has become
     effective under the Act, no stop order suspending the effectiveness of the
     Registration Statement or any part thereof has been issued and no
     proceeding for that purpose has been instituted or threatened or, to the
     best knowledge of the Company, contemplated by the Commission or the
     securities authority of any state or other jurisdiction.
 
          (iii) When any Preliminary Prospectus or any amendment or supplement
     thereto was filed with the Commission it (A) contained all statements
     required to be stated therein in accordance with, and complied in all
     material respects with the requirements of, the Act and the rules and
     regulations of the Commission thereunder and (B) did not include any untrue
     statement of a material fact or omit to state any material fact necessary
     in order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading. When the Registration Statement
     or any amendment thereto was or is declared effective, and at each Time of
     Delivery (as hereinafter defined), it (A) contained or will contain all
     statements required to be stated therein in accordance with, and
 
                                        2
<PAGE>   3
 
     complied or will comply in all material respects with the requirements of,
     the Act and the rules and regulations of the Commission thereunder and (B)
     did not or will not include any untrue statement of a material fact or omit
     to state any material fact necessary to make the statements therein not
     misleading. When (A) the Prospectus or any amendment or supplement thereto
     is filed with the Commission pursuant to Rule 424(b) (or, if the Prospectus
     or such amendment or supplement is not required to be so filed, when the
     Registration Statement or the amendment thereto containing such amendment
     or supplement to the Prospectus was or is declared effective) or (B) any
     Term Sheet that is a part of the Prospectus is filed with the Commission
     pursuant to Rule 434, and at each Time of Delivery, the Prospectus, as
     amended or supplemented at any such time, (1) contained or will contain all
     statements required to be stated therein in accordance with, and complied
     or will comply in all material respects with the requirements of, the Act
     and the rules and regulations of the Commission thereunder and (2) did not
     or will not include any untrue statement of a material fact or omit to
     state any material fact necessary in order to make the statements therein,
     in the light of the circumstances under which they were made, not
     misleading. The foregoing provisions of this paragraph (iii) do not apply
     to statements or omissions made in any Preliminary Prospectus and any
     amendment or supplement thereto, the Registration Statement or any
     amendment thereto, the Prospectus or any amendment or supplement thereto,
     or any Term Sheet in reliance upon and in conformity with written
     information furnished to the Company by any Underwriter through you
     specifically for use therein.
 
          (iv) If the Company has elected to rely on Rule 462(b) and the Rule
     462(b) Registration Statement has not been declared effective (A) the
     Company has filed a Rule 462(b) Registration Statement in compliance with
     and that is effective upon filing pursuant to Rule 462(b) and has received
     confirmation of its receipt; and (B) the Company has given irrevocable
     instructions for transmission of the applicable filing fee in connection
     with the filing of the Rule 462(b) Registration Statement, in compliance
     with Rule 111 promulgated under the Act, or the Commission has received
     payment of such filing fee.
 
          (v) The descriptions in the Registration Statement and the Prospectus
     of statutes, legal and governmental proceedings or contracts and other
     documents are accurate and fairly present the information required to be

     required to be described in the Registration Statement or the Prospectus
     that are not described as required and no contracts or documents of a
     character that are required to be described in the Registration Statement
     or the Prospectus or to be filed as exhibits to the Registration Statement
     that are not described and filed as required.

     its business as described in the Prospectus. The Company has full power and
     authority (corporate and other) to enter into this Agreement and to perform
     its obligations hereunder. Each of the Company and its subsidiaries is duly
     qualified to transact business as a foreign corporation and is in good
     standing under the laws of each other jurisdiction in which it owns or
     leases properties, or conducts any business, so as to require such
     qualification, except where the failure to so qualify would not have a
     material adverse effect on the financial position, results of operations or
     business of the Company and its subsidiaries.
 
          (vii) The Company's authorized, issued and outstanding capital stock
     is as disclosed in the Prospectus. All of the issued shares of capital
     stock of the Company have been duly authorized and validly issued, are

     Stock contained in the Prospectus. None of the issued shares of capital
     stock of the Company or any of its subsidiaries has been issued or is owned
     or held in violation of any preemptive rights of shareholders, and no
     person or entity (including any holder of outstanding shares of capital
     stock of the Company or its subsidiaries) has any preemptive or other
     rights to subscribe for any of the Shares.

     or decree, otherwise than as disclosed in or contemplated by the
     Prospectus.
 
          (xi) Since the respective dates as of which information is given in
     the Registration Statement and the Prospectus, (A) neither the Company nor

     of business, that are material to the Company and its subsidiaries, (B) the

     statement under the Act with respect to any securities of the Company owned
     or to be owned by such person or to require the Company to include such
     securities in the securities registered pursuant to the Registration
     Statement (or any such right has been effectively waived) or any securities
     being registered pursuant to any other registration statement filed by the
     Company under the Act.
 
          (xiv) All offers and sales of the Company's capital stock prior to the
     date hereof were at all relevant times duly registered under the Act or
     exempt from the registration requirements of the Act by reason of Sections
     3(b), 4(2) or 4(6) thereof and were duly registered or the subject of an

          (xvi) The issue and sale of the Shares to be issued and sold by the
     Company and the performance of this Agreement and the consummation of the
     transactions herein contemplated will not conflict with, or

     agreement, lease or other agreement or instrument to which the Company or
     any of its subsidiaries is a party or to which any of their respective
     properties or assets is subject, nor will such action conflict with or
     violate any provision of the Articles of Incorporation or Bylaws of the
     Company or any of its subsidiaries or any statute, rule or regulation or
     any order, judgment or decree of any court or governmental agency or body
     having jurisdiction over the Company or any of its subsidiaries or any of
     their respective properties or assets.
 
          (xvii) The Company and its subsidiaries have good and marketable title
     in fee simple to all real property, if any, and good title to all personal
     property owned by them, in each case free and clear of all liens, security
     interests, pledges, charges, encumbrances, mortgages and defects, except
     such as are disclosed in the Prospectus or such as do not materially and
     adversely affect the value of such property and do not interfere with the
     use made or proposed to be made of such property by the Company and its
     subsidiaries, provided, however, that SouthTrust Bank of Alabama, National
     Association, First Alabama Bank and Core State Bank, N.A. have a security
     interest in certain assets of the Company pursuant to the Credit Agreement
     dated August 16, 1995; and any real property and buildings held under lease

     proposed to be made of such property and buildings by the Company or such
     subsidiary.

     governmental agency or body is required for the issue and sale of the
     Shares or the consummation of the transactions contemplated by this
     Agreement, except the registration of the Shares under the Act (which, if
     the Registration Statement is not effective as of the time of execution
     hereof, shall be obtained as provided in this Agreement) and such as may be
     required under state securities or blue sky laws in connection with the

     litigation, arbitration, claim, proceeding (formal or informal) or
     investigation pending or threatened (or any basis therefor) in which the
     Company or any of its subsidiaries is a party or of which any of their
     respective properties or assets are the subject which, if determined
     adversely to the Company or any such subsidiary, would individually or in
     the aggregate have a material adverse effect on the financial position,
     results of operations or business of the Company and its subsidiaries.
     Neither the Company nor any of its subsidiaries is in violation of, or in
     default with respect to, any statute, rule, regulation, order, judgment or

     use therein.
 
     In order to document the Underwriters' compliance with the reporting and
withholding provisions of the Internal Revenue Code of 1986, as amended, with
respect to the transactions herein contemplated, each of the Selling
Stockholders agrees to deliver to you prior to or at the First Time of Delivery
(as hereinafter defined) a properly completed and executed United States
Treasury Department Form W-9 (or other applicable form or statement specified by
Treasury Department regulations in lieu thereof).
 
     Each of the Selling Stockholders represents and warrants that certificates
in negotiable form representing all of the Shares to be sold by such Selling
Stockholder hereunder have been placed in custody under a Custody Agreement, in
the form heretofore furnished to and approved by you, duly executed and
delivered by such Selling Stockholder to ChaseMellon Shareholders Services as
custodian (the "Custodian"), and that such Selling Stockholder has duly executed
and delivered a Power of Attorney, in the form heretofore furnished to and
approved by you, appointing the persons indicated in Schedule II hereto as such

to execute and deliver this Agreement on behalf of such Selling Stockholder, to
determine the purchase price to be paid by the Underwriters to the Selling
Stockholders as provided in Section 2 hereof, to authorize the delivery of the
Shares to be sold by such Selling Stockholder hereunder and otherwise to act on
behalf of such Selling Stockholder in connection with the transactions
contemplated by this Agreement and the Custody Agreement.
 
     Each of the Selling Stockholders specifically agrees that the Shares
represented by the certificates held in custody for such Selling Stockholder
under the Custody Agreement are subject to the interests of the Underwriters
hereunder, and that the arrangements made by such Selling Stockholder for such
custody, and the appointment by such Selling Stockholder of the
Attorneys-in-Fact by the Power of Attorney, are irrevocable. Each of the Selling
Stockholders specifically agrees that the obligations of the Selling
Stockholders hereunder shall not be terminated by operation of law, whether by
death or incapacity of any individual Selling Stockholder or, in the case of an
estate or trust, by the death or incapacity of any executor or trustee or the
termination of such estate or trust, or in the case of a partnership or
corporation, by the dissolution of such partnership or corporation, or by the
occurrence of any other event.

jointly, to sell to each of the Underwriters, and each of the Underwriters
agrees, severally and not jointly, to purchase from the Company and each Selling
Stockholder, at a purchase price of $     per share, the number of Firm Shares
(to be adjusted by you so as to eliminate fractional shares) determined by
multiplying the aggregate number of Shares to be sold by the Company and the
Selling Stockholders as set forth opposite their respective names in Schedule II
hereto by a fraction, the numerator of which is the aggregate number of Firm
Shares to be purchased by such Underwriter as set forth opposite the name of
such Underwriter in Schedule I hereto, and the denominator of which is the
aggregate number of Firm Shares to be purchased by the Underwriters from the
Company and the Selling Stockholders hereunder, and (b) in the event and to the
extent that the Underwriters shall exercise the election to purchase Optional
Shares as provided below, the Company agrees to issue and sell to each of the
 
                                        9
<PAGE>   10
 
Underwriters, and each of the Underwriters agrees, severally and not jointly, to
purchase from the Company, at the purchase price per share set forth in clause
(a) of this Section 2, that portion of the number of Optional Shares as to which
such election shall have been exercised (to be adjusted by you so as to
eliminate fractional shares) determined by multiplying such number of Optional
Shares by a fraction, the numerator of which is the maximum number of Optional
Shares that such Underwriter is entitled to purchase as set forth opposite the
name of such Underwriter in Schedule I hereto and the denominator of which is
the maximum number of the Optional Shares that all of the Underwriters are
entitled to purchase hereunder.
 
     The Company hereby grants to the Underwriters the right to purchase at
their election in whole or in part from time to time up to 150,000 Optional
Shares, at the purchase price per share set forth in clause (a) in the paragraph
above, for the sole purpose of covering over-allotments in the sale of Firm
Shares. Any such election to purchase Optional Shares may be exercised by
written notice from you to the Company, given from time to time within a period
of 30 calendar days after the date of this Agreement and setting forth the
aggregate number of Optional Shares to be purchased and the date on which such
Optional Shares are to be delivered, as determined by you but in no event
earlier than the First Time of Delivery (as hereinafter defined) or, unless you
and the Company otherwise agree in writing, earlier than two or later than ten
business days after the date of such notice. In the event you elect to purchase
all or a portion of the Optional Shares, the Company agrees to furnish or cause
to be furnished to you the certificates, letters and opinions, and to satisfy
all conditions, set forth in Section 7 hereof at each Subsequent Time of
Delivery (as hereinafter defined).
 
     3. Offering by the Underwriters.  Upon the authorization by you of the
release of the Shares, the several Underwriters propose to offer the Shares for

behalf of the Company and the Selling Stockholders to you for the account of
such Underwriter, against payment by such Underwriter on its behalf of the
purchase price therefor by official bank check or checks (payable in next day
funds) drawn on an Atlanta, Georgia bank, payable to the order of the Company in
next day available funds. The closing of the sale and purchase of the Shares
shall be held at the offices of King & Spalding, 191 Peachtree Street, Atlanta,
Georgia 30303, except that physical delivery of such certificates shall be made
at the office of The Depository Trust Company, 55 Water Street, New York, New

date as you, the Company and the Attorneys-in-Fact, on behalf of the Selling
Stockholders, may agree upon in writing, and, with respect to the Optional
Shares, at 10:00 a.m., Atlanta time, on the date specified by you in the written
notice given by you of the Underwriters' election to purchase all or part of
such Optional Shares, or at such other time and date as you and the Company may

          (ii) The Company will not file with the Commission the Prospectus or
     the amendment referred to in the second sentence of Section 1(a)(i) hereof,
     any amendment or supplement to the Prospectus, any Term Sheet, any
     amendment to the Registration Statement or any Rule 462(b) Registration
     Statement unless you have received a reasonable period of time to review
     any such proposed amendment or supplement and consented to the filing
     thereof and will use its best efforts to cause any such amendment to the
     Registration Statement to be declared effective as promptly as possible.
     Upon the request of the Representatives or counsel for the Underwriters,
     the Company will promptly prepare and file with the Commission, in
     accordance with the rules and regulations of the Commission, any amendments
     to the Registration Statement or any amendments or supplements to the
     Prospectus or any Term Sheet that may be necessary or advisable in
     connection with the distribution of the Shares by the several Underwriters
     and will use its best efforts to cause any such amendment to the
     Registration Statement to be declared effective as promptly as possible. If
     required, the Company will file any amendment or supplement to the
     Prospectus or any Term Sheet with the Commission in the manner and within
     the time period required by Rule 424(b) and Rule 434, as applicable, under
     the Act. The Company will advise the Representatives, promptly after
     receiving notice thereof, of the time when the Original Registration
     Statement or any amendment thereto or any Rule 462(b) Registration
     Statement has been filed or declared effective or the Prospectus or any
     amendment or supplement thereto has been filed and will provide evidence to
     the Representatives of each such filing or effectiveness.
 
          (iii) The Company will advise you promptly after receiving notice or
     obtaining knowledge of (A) the issuance by the Commission of any stop order
     suspending the effectiveness of the Original Registration Statement or any

     preventing or suspending the use of any Preliminary Prospectus or the
     Prospectus or any amendment or supplement thereto, (B) the suspension of
     the qualification of the Shares for offer or sale in any jurisdiction or of
     the initiation or threatening of any proceeding for any such purpose, or

     other jurisdiction for amending the Original Registration Statement or any
     Rule 462(b) Registration Statement, for amending or supplementing the
     Prospectus or for additional information. The Company will use its best
     efforts to prevent the issuance of any such stop order and, if any such
     stop order is issued, to obtain the withdrawal thereof as promptly as
     possible.
 
          (iv) If the delivery of a prospectus relating to the Shares is
     required under the Act at any time prior to the expiration of nine months
     after the date of the Prospectus and if at such time any events have
     occurred as a result of which the Prospectus as then amended or
     supplemented would include an untrue statement of a material fact or omit
     to state any material fact necessary in order to make the statements
     therein, in light of the circumstances under which they were made, not
     misleading, or if for any reason it is necessary during such same period to
     amend or supplement the Prospectus or to file under the Exchange Act any
     document incorporated by reference in the Prospectus to comply with the Act
     or the Exchange Act or the respective rules and regulations thereunder, the
     Company will promptly notify you and upon your request (but at the
     Company's expense) prepare and file with the Commission an amendment or
     supplement to the Prospectus or any such incorporated document that
     corrects such statement or omission or effects such compliance and will
     furnish without charge to each Underwriter and to any dealer in securities
     as many copies of such amended or supplemented Prospectus as you may from
     time to time reasonably request. If the delivery of a prospectus relating

     after the date of the Prospectus, upon your request but at the expense of
     such Underwriter, the Company will prepare and deliver to such Underwriter
     as many copies as you may request of an amended or supplemented Prospectus
     complying with Section 10(a)(3) of the Act. Neither your consent to, nor
     the Underwriters' delivery of, any such amendment or supplement shall
     constitute a waiver of any of the conditions set forth in Section 7.

          (v) The Company promptly from time to time will take such action as
     you may reasonably request to qualify the Shares for offering and sale
     under the securities or blue sky laws of such jurisdictions as you may
     request and will continue such qualifications in effect for as long as may
     be necessary to complete the distribution of the Shares, provided that in

     foreign corporation or to file a general consent to service of process in
     any jurisdiction.
 
          (vi) The Company will promptly provide you, without charge, (A) three

        its properties and conduct its business as described in the Registration

        transact business as a foreign corporation and is in good standing under
        the laws of each other jurisdiction in which it owns or leases property,
        or conducts any business, so as to require such qualification, except

        other jurisdiction in which it owns or leases property, or conducts any
        business, so as to require such qualification, except where the failure
        to so qualify would not have a material adverse effect on the financial
        position, results of operations or business of the Company and its
        subsidiaries.

        outstanding shares of capital stock of the Company or its subsidiaries)
        has any preemptive or other rights to subscribe for any of the Shares.
 
             (iv) All of the issued shares of capital stock of each of the
        Company's subsidiaries have been duly authorized and validly issued, are
        fully paid and nonassessable, and are owned beneficially by the Company
        free and clear of all liens, security interests, pledges, charges,
        encumbrances, shareholders' agreements, voting trusts, defects, equities
        or claims of any nature whatsoever. Other than the subsidiaries listed
        on Exhibit 21.1 to the Registration Statement, the Company does not own,
        directly or indirectly, any capital stock or other equity securities of
        any other corporation or any ownership interest in any partnership,
        joint venture, limited liability company or other association other than
        as disclosed in the Prospectus.
 
             (v) Except as disclosed in the Prospectus, there are no outstanding
        (A) securities or obligations of the Company or any of its subsidiaries
        convertible into or exchangeable for any capital stock of the Company or
        any such subsidiary, (B) warrants, rights or options to subscribe for or
        purchase from the Company or any such subsidiary any such capital stock

        shares of capital stock, any such convertible or exchangeable securities
        or obligations, or any such warrants, rights or options.
 
             (vi) The Shares to be issued and sold by the Company have been duly
        authorized and, when issued and delivered against payment therefor as
        provided herein, will be validly issued and fully paid and nonassessable
        and will conform to the description of the Common Stock contained in the
        Prospectus; the certificates evidencing the Shares comply with all
        applicable requirements of Delaware law; the Shares have been listed on
        the Nasdaq National Market.
 
             (vii) Except as disclosed in the Prospectus, there are no
        contracts, agreements or understandings between the Company and any
        person granting such person the right to require the Company to file a
        registration statement under the Act with respect to any securities of
        the Company owned or to be owned by such person or to require the
        Company to include such securities in the securities registered pursuant
        to the Registration Statement (or any such right has been effectively
        waived) or in any securities being registered pursuant to any other
        registration statement filed by the Company under the Act.
 
             (viii) All offers and sales of the Company's capital stock prior to
        the date hereof were at all relevant times duly registered under the Act
        or exempt from the registration requirements of the Act by reason of
        Sections 3(b), 4(2) or 4(6) thereof and were duly registered or the
        subject of an available exemption from the registration requirements of
        the applicable state securities or blue sky laws.
 
             (ix) Neither the Company nor any of its subsidiaries is, or with
        the giving of notice or passage of time or both, would be, in violation
        of its Articles of Incorporation or Bylaws or in default under any
        indenture, mortgage, deed of trust, loan agreement, lease or other
        agreement or instrument to which the Company or any such subsidiary is a
        party or to which any of their respective properties or assets is
        subject.
 
             (x) The issue and sale of the Shares being issued at such Time of
        Delivery and the performance of this Agreement and the consummation of
        the transactions herein contemplated will not conflict with, or (with or
        without the giving of notice or the passage of time or both) result in a
        breach or violation of any of the terms or provisions of, or constitute
        a default under, any indenture, mortgage, deed of trust, loan agreement,
        lease or other agreement or instrument to which the
 
                                       15
<PAGE>   16
 
        Company or any such subsidiary is a party or to which any of their
        respective properties or assets is subject, nor will such action
        conflict with or violate any provision of the Articles of Incorporation
        or Bylaws of the Company or any of its subsidiaries or any statute, rule
        or regulation or any order, judgment or decree of any court or
        governmental agency or body having jurisdiction over the Company or any
        of its subsidiaries or any of their respective properties or assets.
 
             (xi) The Company and its subsidiaries have good and marketable
        title in fee simple to all real property and good title to all personal
        property owned by them, in each case free and clear of all liens,
        security interests, pledges, charges, encumbrances, mortgages and
        defects except such as are disclosed in the Prospectus or such as do not
        materially and adversely affect the value of such property and do not
        interfere with the use made and proposed to be made of such property by
        the Company and its subsidiaries; and any real property and buildings
        held under lease by the Company or any of its subsidiaries are held by
        the Company or such subsidiary under valid, subsisting and enforceable
        leases with such exceptions as are disclosed in the Prospectus or are
        not material and do not interfere with the use made and proposed to be
        made of such property and buildings by the Company or such subsidiary.
 
             (xii) No consent, approval, authorization, order or declaration of
        or from, or registration, qualification or filing with, any court or
        governmental agency or body is required for the issue and sale of the
        Shares or the consummation of the transactions contemplated by this
        Agreement, except the registration of the Shares under the Act and such
        as may be required under state securities or blue sky laws in connection
        with the offer, sale and distribution of the Shares by the Underwriters.
 
             (xiii) To such counsel's knowledge and other than as disclosed in
        or contemplated by the Prospectus, there is no litigation, arbitration,
        claim, proceeding (formal or informal) or investigation pending or
        threatened (or any basis therefor) in which the Company or any of its
        subsidiaries is a party or of which any of their respective properties
        or assets is the subject which, if determined adversely to the Company
        or any such subsidiary, would individually or in the aggregate have a
        material adverse effect on the financial position, results of operations
        or business of the Company and its subsidiaries; and, to such counsel's
        knowledge, neither the Company nor any of its subsidiaries is in
        violation of, or in default with respect to, any statute, rule,
        regulation, order, judgment or decree, except as described in the
        Prospectus, nor is the Company or any subsidiary required to take any
        action in order to avoid any such violation or default.
 
             (xiv) This Agreement has been duly authorized, executed and
        delivered by the Company.
 
             (xv) The Registration Statement, any Rule 462(b) Registration
        Statement and the Prospectus and each amendment or supplement thereto
        (other than the financial statements and related schedules therein, as
        to which such counsel need express no opinion), as of their respective
        effective or issue dates, complied as to form in all material respects
        with the requirements of the Act and the Exchange Act and the respective
        rules and regulations thereunder. The descriptions in the Registration
        Statement and the Prospectus of statutes, legal and governmental
        proceedings or contracts and other documents are accurate and fairly
        present the information required to be shown; and such counsel do not
        know of any statutes or legal or governmental proceedings required to be
        described in the Registration Statement, any Rule 462(b) Registration
        Statement or Prospectus that are not described as required or of any
        contracts or documents of a character required to be described in the
        Registration Statement or Prospectus or to be filed as exhibits to the
        Registration Statement which are not described and filed as required.
 
             (xvi) Each of the Registration Statement and any Rule 462(b)
        Registration Statement is effective under the Act; any required filing
        of the Prospectus or any Term Sheet pursuant to Rule 424(b) or Rule 434,
        as applicable, has been made in the manner and within the time period
        required by Rule 424(b) or Rule 434, as applicable; and no stop order
        suspending the effectiveness of the Registration Statement or any Rule
        462(b) Registration Statement, respectively, or any part thereof has
        been issued and, to such counsel's knowledge, no proceedings for that
        purpose have been instituted or threatened or are contemplated by the
        Commission.
 
                                       16
<PAGE>   17
 
             (xvii) The Company is not, and will not be as a result of the
        consummation of the transactions contemplated by this Agreement, an
        "investment company," or a company "controlled" by an "investment
        company," within the meaning of the Investment Company Act of 1940.
 
             (xviii) If the Company elects to rely upon Rule 434, the Prospectus
        is not "materially different", as such term is used in Rule 434, from
        the prospectus included in the Registration Statement at the time of its
        effectiveness or an effective post-effective amendment thereto
        (including such information that is permitted to be omitted pursuant to
        Rule 430A).
 
     Such counsel shall also state that they have no reason to believe that the
Registration Statement, or any further amendment thereto made prior to such Time
of Delivery, on its effective date and as of such time of Delivery, contained or
contains any untrue statement of a material fact or omitted or omits to state
any material fact required to be stated therein or necessary to make the
statements therein not misleading, or that the Prospectus, or any amendment or
supplement thereto made prior to such Time of Delivery, as of its issue date and
as of such Time of Delivery, contained or contains any untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in light of the circumstances under which they were
made, not misleading (provided that such counsel need express no belief
regarding the financial statements and related schedules and other financial
data contained in the Registration Statement, any amendment thereto, or the
Prospectus, or any amendment or supplement thereto).
 
     In rendering any such opinion, such counsel may rely, as to matters of
fact, to the extent such counsel deem proper, on certificates of responsible
officers of the Company and public officials.
 
     (d) You shall have received an opinion, dated such Time of Delivery, of
Lanier Ford Shaver & Payne P.C., counsel for the Selling Stockholders in form
and substance satisfactory to you and your counsel, to the effect that:
 
          (i) A Power of Attorney and a Custody Agreement have been duly
     executed and delivered by such Selling Stockholder, each of which is
     enforceable against such Selling Stockholder in accordance with its terms
     subject, as to enforcement, to applicable bankruptcy insolvency,
     reorganization and moratorium laws and other laws relating to or affecting
     the enforcement of creditors' rights generally and to general equitable
     principles.
 
          (ii) This Agreement has been duly executed and delivered by or on
     behalf of such Selling Stockholder; the sale of the Shares to be sold by
     such Selling Stockholder at such Time of Delivery and the performance 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 (with or without the giving of notice or the passage of
     time or both) result in a breach or violation of any of the terms or
     provisions of, or constitute a default under, any indenture, mortgage, deed
     of trust, loan agreement, lease or other agreement or instrument to which
     such Selling Stockholder is a party or to which any of its properties or
     assets is subject, nor will such action conflict with or violate any
     statute, rule or regulation or any order, judgment or decree of any court
     or governmental agency or body having jurisdiction over such Selling
     Stockholder or any of such Selling Stockholder's properties or assets.
 
          (iii) No consent, approval, authorization, order of declaration of or
     from, or registration, qualification or filing with, any court or
     governmental agency or body is required for the issue and sale of the
     Shares being sold by such Selling Stockholder or the consummation of the
     transactions contemplated by this Agreement, the Power of Attorney or the
     Custody Agreement, except the registration of such Shares under the Act and
     such as may be required under state securities or blue sky laws in
     connection with the offer, sale and distribution of such Shares by the
     Underwriters.
 
          (iv) Such Selling Stockholder has, and immediately prior to such Time
     of Delivery such Selling Stockholder will have, good and valid title to the
     Shares to be sold by such Selling Stockholder hereunder, free and clear of
     all liens, security interests, pledges, charges, encumbrances, defects,
     shareholders' agreements, voting trusts, equities or claims of any nature
     whatsoever; and, upon delivery of such Shares against payment therefor as
     provided herein, good and valid title to such Shares, free and
 
                                       17
<PAGE>   18
 
     clear of all liens, security interests, pledges, charges, encumbrances,
     defects, shareholders' agreements, voting trusts, equities or claims of any
     nature whatsoever, will pass to the several Underwriters.
 
     In rendering any such opinion, such counsel may rely, as to matters of
fact, to the extent such counsel deem proper, on certificates of responsible
officers of the Company, the Selling Stockholders and public officials.
 
     (e) You shall have received from Ernst & Young LLP letters dated,
respectively, the date hereof (or, if the Registration Statement has been
declared effective prior to the execution and delivery of this Agreement, dated
such effective date and the date of this Agreement) and each Time of Delivery,
in form and substance satisfactory to you, to the effect set forth in Annex I
hereto. In the event that the letters referred to in this Section 7(e) set forth
any changes, decreases or increases in the items specified in paragraph (iv) of
Annex I, it shall be a further condition to the obligations of the Underwriters
that (i) such letters shall be accompanied by a written explanation by the
Company as to the significance thereof, unless the Representatives deem such
explanation unnecessary, and (ii) such changes, decreases or increases do not,
in your sole judgment, make it impracticable or inadvisable to proceed with the
purchase, sale and delivery of the Shares being delivered at such Time of
Delivery as contemplated by the Registration Statement, as amended as of the
date of such letter.
 
     (f) Since the date of the latest audited financial statements included in
the Prospectus, neither the Company nor any of its subsidiaries shall have
sustained (i) any loss or interference with their respective businesses from
fire, explosion, flood, hurricane 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 disclosed in or contemplated by the Prospectus, or
(ii) any change, or any development involving a prospective change (including
without limitation a change in management or control of the Company), in or
affecting the position (financial or otherwise), results of operations, net
worth or business prospects of the Company and its subsidiaries, otherwise than
as disclosed in or contemplated by the Prospectus, the effect of which, in
either such case, is in your judgment so material and adverse as to make it
impracticable or inadvisable to proceed with the purchase, sale and delivery of
the Shares being delivered at such Time of Delivery as contemplated by the
Registration Statement, as amended as of the date hereof.
 
     (g) Subsequent to the date hereof there shall not have occurred any of the
following: (i) any suspension or limitation in trading in securities generally
on the New York Stock Exchange, or any setting of minimum prices for trading on
such exchange, or in the Common Stock by the Commission or the Nasdaq Stock
Market; (ii) a moratorium on commercial banking activities in New York declared
by either federal or state authorities; or (iii) any outbreak or escalation of
hostilities involving the United States, declaration by the United States of a
national emergency or war or any other national or international calamity or
emergency if the effect of any such event specified in this clause (iv) in your
judgment makes it impracticable or inadvisable to proceed with the purchase,
sale and delivery of the Shares being delivered at such Time of Delivery as
contemplated by the Registration Statement, as amended as of the date hereof.
 
     (h) The Company shall have furnished to you at such Time of Delivery
certificates of officers of the Company and certificates of the Selling
Stockholders, satisfactory to you as to the accuracy of the representations and
warranties of the Company and such Selling Stockholders herein at and as of such
Time of Delivery, as to the performance by the Company and such Selling
Stockholders of all of their respective obligations hereunder to be performed at
or prior to such Time of Delivery, and as to such other matters as you may
reasonably request, and the Company shall have furnished or caused to be
furnished certificates as to the matters set forth in subsections (a) and (f) of
this Section 7, and as to such other matters as you may reasonably request.
 
     (i) The Shares shall have been approved for inclusion in the Nasdaq
National Market.
 
     8. Indemnification and Contribution.  (a) The Company agrees to indemnify
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 made by
 
                                       18
<PAGE>   19
 
the Company in Section 1 of this Agreement; (ii) any untrue statement or alleged
untrue statement of any material fact contained in (A) the Registration
Statement or any amendment thereto, any Preliminary Prospectus or the Prospectus
or any amendment or supplement thereto, or (B) any application or other
document, or any amendment or supplement thereto, executed by the Company or
based upon written information furnished by or on behalf of the Company filed in
any jurisdiction in order to qualify the Shares under the securities or blue sky
laws thereof or filed with the Commission or any securities association or
securities exchange (each an "Application"); or (iii) the omission or alleged
omission to state in the Registration Statement or any amendment thereto, any
Preliminary Prospectus, the Prospectus or any amendment or supplement thereto,
or any Application a material fact required to be stated therein or necessary to
make the statements therein not misleading, and will reimburse each Underwriter
for any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating, defending against or appearing as a third-party
witness in connection with any such loss, claim, damage, liability or action;
provided, however, that the Company shall not be liable in any such case to the
extent that any such loss, claim, damage, liability or action arises out of or
is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in the Registration Statement or any Rule 462(b)
Registration Statement or any amendment thereto, any Preliminary Prospectus, the
Prospectus or any amendment or supplement thereto or any Application in reliance
upon and in conformity with written information furnished to the Company by any
Underwriter through you expressly for use therein. The Company will not, without
the prior written consent of each Underwriter, settle or compromise or consent
to the entry of any judgment in any pending or threatened claim, action, suit or
proceeding (or related cause of action or portion thereof) in respect of which
indemnification may be sought hereunder (whether or not such Underwriter is a
party to such claim, action, suit or proceeding), unless such settlement,
compromise or consent includes an unconditional release of such Underwriter from
all liability arising out of such claim, action, suit or proceeding (or related
cause of action or portion thereof).
 
     (b) Each Selling Stockholder, jointly and severally, agrees to indemnify
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 made by such Selling
Stockholder in Section 1(b) of this Agreement; or (ii) any untrue statement or
alleged untrue statement of any material fact contained in the Registration
Statement or any amendment thereto, any Preliminary Prospectus, 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
misleading, and will reimburse each Underwriter for any legal or other expenses
reasonably incurred by such Underwriter in connection with investigating,
defending against or appearing as a third-party witness in connection with any
such loss, claim, damage, liability or action; provided, however, that no such
Selling Stockholder shall be liable in any such case to the extent that any such
loss, claim, damage, liability or action arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in the Registration Statement or any amendment thereto, any Preliminary
Prospectus, the Prospectus or any amendment or supplement thereto or any
Application in reliance upon and in conformity with written information
furnished to the Company by any Underwriter through you expressly for use
therein; provided, further, however, that such Selling Stockholders shall be
liable hereunder in any case only to the extent of the total net proceeds from
the offering (before deducting expenses) received by such Selling Stockholders
from the underwriters for the Shares sold by such Selling Stockholders hereunder
unless 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 or any amendment or supplement thereto, any
Preliminary Prospectus, the Prospectus or any amendment or supplement thereto or
any Application in reliance upon and conformity with written information
furnished to the Company by such Selling Stockholders expressly for use therein,
in which case such limitation of the liability of such Selling Stockholders
shall not apply. No Selling Stockholder will, without the prior written consent
of each Underwriter, settle or compromise or consent to the entry of any
judgment in any pending or threatened claim, action, suit or proceeding (or
related cause of action or portion thereof) in respect of which indemnification
may be sought thereunder (whether or not such Underwriter is a
 
                                       19
<PAGE>   20
 
party to such claim, action, suit or proceeding), unless such settlement,
compromise or consent includes an unconditional release of such Underwriter from
all liability arising out of such claim, action, suit or proceeding (or related
cause of action or portion thereof).
 
     (c) Each Underwriter, severally but not jointly, agrees to indemnify and
hold harmless the Company and each Selling Stockholder against any losses,
claims, damages or liabilities to which the Company or any 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 any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement or any amendment thereto, any
Preliminary Prospectus, 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 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 reliance upon and in
conformity with written information furnished to the Company by such Underwriter
through you expressly for use therein; and will reimburse the Company and each
Selling Stockholder for any legal or other expenses reasonably incurred by the
Company in connection with investigating or defending any such loss, claim,
damage, liability or action.
 
     (d) Promptly after receipt by an indemnified party under subsection (a),
(b) or (c) 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); provided, however, that if the defendants in any such action include
both the indemnified party and the indemnifying party and the indemnified party
shall have reasonably concluded that there may be one or more legal defenses
available to it or other indemnified parties which are different from or
additional to those available to the indemnifying party, the indemnifying party
shall not have the right to assume the defense of such action on behalf of such
indemnified party and such indemnified party shall have the right to select
separate counsel to defend such action on behalf of such indemnified party.
After such notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof and approval by such indemnified party
of counsel appointed to defend such action, the indemnifying party will not be
liable to such indemnified party under this Section 8 for any legal or other
expenses, other than reasonable costs of investigation, subsequently incurred by
such indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that in
connection with such action the indemnifying party shall not be liable for the
expenses of more than one separate counsel (in addition to local counsel) in any
one action or separate but substantially similar actions in the same
jurisdiction arising out of the same general allegations or circumstances, which
separate counsel shall be designated by the Representatives in the case of
indemnity arising under paragraph (a) or (b) of this Section 8 or (ii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party. Nothing in this Section 8(d)
shall preclude an indemnified party from participating at its own expense in the
defense of any such action so assumed by the indemnifying party.
 
     (e) If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a), (b)
or (c) 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
 
                                       20
<PAGE>   21
 
permitted by applicable law or if the indemnified party failed to give the
notice required under subsection (d) 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
that 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. 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, the
Selling Stockholders and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this subsection (e) 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 (e). 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 (e) 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 (e), 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 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 (e) to contribute are several in proportion to
their respective underwriting obligations and not joint.
 
     (f) The obligations of the Company and the Selling Stockholders under this
Section 8 shall be in addition to any liability which the Company or such
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 within the meaning of the Act.
 
     9. Default of Underwriters.  (a) If any Underwriter defaults in its
obligation to purchase Shares 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 (36) hours after such default by
any Underwriter you do not arrange for the purchase of such Shares, the Company
shall be entitled to a further period of thirty-six (36) 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 that in your opinion may thereby be made necessary. The cost of
preparing, printing and filing any such amendments shall be paid for by the
Underwriters. 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.
 
                                       21
<PAGE>   22
 
     (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 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 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.
 
     10. Termination.  (a) This Agreement may be terminated with respect to the
Firm Shares or any Optional Shares in the sole discretion of the Representatives
by notice to the Company given prior to the First Time of Delivery or any
Subsequent Time of Delivery, respectively, in the event that (i) any condition
to the obligations of the Underwriters set forth in Section 7 hereof has not
been satisfied, or (ii) the Company or the Selling Stockholders shall have
failed, refused or been unable to deliver the Shares or to perform all
obligations and satisfy all conditions on its part to be performed or satisfied
hereunder at or prior to such Time of Delivery, in either case other than by
reason of a default by any of the Underwriters. If this Agreement is terminated
pursuant to this Section 10(a), the Company and the Selling Stockholders, pro
rata in accordance with the number of shares proposed to be sold hereunder will
reimburse the Underwriters severally upon demand for all out-of-pocket expenses
(including counsel fees and disbursements) that shall have been incurred by them
in connection with the proposed purchase and sale of the Shares. Neither the
Company nor any Selling Stockholder shall in any event be liable to any of the
Underwriters for the loss of anticipated profits from the transactions covered
by this Agreement.
 
     (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 Section 9(a), the aggregate number of
such Shares which remains unpurchased exceeds one-eleventh of the aggregate
number of Shares to be purchased at such Time of Delivery, or if the Company and
the Selling Stockholders shall not exercise the right described in Section 9(b)
to require non-defaulting Underwriters to purchase Shares of a defaulting
Underwriter or Underwriters, then this Agreement (or, with respect to a
Subsequent Time of Delivery, the obligations of the Underwriters to purchase and
of the Company to sell the Optional Shares) shall thereupon terminate, without
liability on the part of any non-defaulting Underwriter, the Company or the
Selling Stockholders, except for the expenses to be borne by the Company, 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.
 
     11. Survival.  The respective indemnities, agreements, representations,
warranties and other statements of the Company, its officers, 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 referred to in Section 8(e) or the Company, any Selling
Stockholder, or any officer or director or controlling person of the Company
referred to in Section 8(e), and shall survive delivery of and payment for the
Shares. The respective agreements, covenants, indemnities and other statements
set forth in Sections 6 and 8 hereof shall remain in full force and effect,
regardless of any termination or cancellation of this Agreement.
 
     12. Notices.  All communications hereunder shall be in writing and, if sent
to any of the Underwriters, shall be mailed, delivered or telegraphed and
confirmed in writing to you in care of The Robinson-Humphrey Company, Inc., 3333

     14. Binding Effect.  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 and controlling persons referred to therein 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.
 
     15. Governing Law.  This Agreement shall be governed by and construed in
accordance with the laws of the State of Georgia without giving effect to any
provisions regarding conflicts of laws.
 
     16. Counterparts.  This Agreement may be executed by any one or more of the

     Pursuant to Section 7(e) of the Underwriting Agreement, Ernst & Young LLP
shall furnish letters to the Underwriters to the effect that:
 
          (i) they are independent public accountants with respect to the
     Company and its consolidated subsidiaries within the meaning the Act and
     the applicable published rules and regulations thereunder;
 
          (ii) in their opinion, the consolidated financial statements and
     schedules audited by them and included in the Prospectus and 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;
 
          (iii) the financial statements of the Company as of and for the
     nine-month period ended May 31, 1996 were reviewed by them in accordance
     with the standards established by the American Institute of Certified
     Public Accountants and based upon their review they are not aware of any
     material modifications that should be made to such financial statements for
     them to be in conformity with generally accepted accounting principles, and
     such financial statements comply as to form in all material respects with
     the applicable accounting requirements of the Act and the applicable rules
     and regulations thereunder;
 
          (iv) On the basis of a reading of the latest available interim
     unaudited consolidated condensed financial statements of the Company and
     its consolidated subsidiaries, a reading of the unaudited amounts for
     revenues and total and per share amounts of net income for the nine months
     ended May 31, 1996 and of the unaudited consolidated financial statements
     of the Company and its consolidated subsidiaries for the periods from which
     such amounts are derived, limited procedures, not constituting an audit 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
     accounting matters and such other inquiries and procedures as may be
     specified in such letter, nothing came to their attention that caused them
     to believe that:
 
             (A) the unaudited consolidated condensed financial statements of
        the Company and its consolidated subsidiaries included in the
        Registration Statement and the Prospectus do not comply in form in all
        material respects with the applicable accounting requirements of the Act
        and the related published rules and regulations thereunder or are not in
        conformity with generally accepted principles applied on a basis
        substantially consistent with that of the audited consolidated financial
        statements included in the Registration Statement and the Prospectus;
 
             (B) the unaudited amounts for revenues and total and per share
        amounts of net income included in the Registration Statement and the
        Prospectus do not agree with the amounts set forth in the unaudited
        consolidated financial statements for those same periods or are not in
        conformity with generally accepted accounting principles applied on a
        basis substantially consistent with that of the corresponding amounts in
        the audited consolidated financial statements included in the
        Registration Statement and the Prospectus; and
 
             (C) as of a specified date not more than 5 days prior to the date
        of such letter, there were any changes in the capital stock (other than
        the issuance of capital stock upon exercise of employee stock options
        that were outstanding on the date of the latest balance sheet included
        in the Prospectus) or any increase in inventories or the long-term debt
        or short-term debt of the Company and its subsidiaries, or any decreases
        in net current assets or net assets or other items specified by the
        Representatives, or any increases in any other items specified by the
        Representatives, in each case as compared with amounts shown in the
        latest balance sheet included in the Prospectus, except in each case for
        changes, increases or decreases which the Prospectus discloses have
        occurred or may occur, or which are described in such letter; and
 
                                       A-1
<PAGE>   28
 
             (D) for the period from the date of the latest financial statements
        included in the Prospectus to the specified date referred to in Clause
        (C) there were any decreases in revenues or operating income or the
        total or per share amounts of net income or other items specified by the
        Representatives, or any increases in any items specified by the
        Representatives, in each case as compared with the comparable period of
        the preceding year and with any other period of corresponding length
        specified by the Representatives, except in each case for increases or
        decreases which the Prospectus discloses have occurred or may occur, or
        which are described in such letter; and
 
          (v) In addition to the audit referred to in their report(s) included
     in the Prospectus and the limited procedures, inspection of minute books,
     inquiries and other procedures referred to in paragraph (iv) above, they
     have carried out certain specified procedures, not constituting an audit in
     accordance with generally accepted auditing standards, with respect to
     certain amounts, percentages and financial information specified by the
     Representatives that are included in the Registration Statement and the
     Prospectus, or which appear in Part II of, or in exhibits or schedules to,
     the Registration Statement and have compared certain of such amounts,
     percentages and financial information with the accounting records of the
     Company and its subsidiaries and have found them to be in agreement.
 
          (vi) on the basis of a reading of the unaudited pro forma consolidated
     condensed 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 paragraph (vi), inquiries of certain officials of the Company
     and its consolidated subsidiaries, Advanced Marine Enterprises, Inc. and
     TXEN, Inc. who have responsibility for financial and accounting matters and
     preparing the pro forma consolidated condensed financial statements,
     nothing came to their attention that caused them to believe that the
     unaudited pro forma consolidated condensed financial statements do not
     comply as to 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.
 
     References to the Registration Statement and the Prospectus in this Annex I
shall include any amendment or supplement thereto at the date of such letter.

          Re:  Form S-3, Registration Statement Relating to the Registration of
               1,000,000 Shares of Common Stock, $.01 Par Value Per Share, of
               Nichols Research Corporation
 
Gentlemen:
 
     We have acted as your counsel in preparation of a Registration Statement on
Form S-3 to be filed by you with the Securities and Exchange Commission and all
amendments thereto (collectively the "Registration Statement") covering
1,000,000 shares of common stock, $.01 par value per share (the "Common Stock"),
to be sold by the Company and certain selling stockholders to the underwriters,
The Robinson-Humphrey Company, Inc., Oppenheimer & Co., Inc., and Ferris, Baker
Watts, Incorporated (the "Underwriters"), for public distribution pursuant to
the Underwriting Agreement among the Company, the selling stockholders and the
Underwriters, filed as an exhibit to the Registration Statement.
 
     In so acting, we have examined the Registration Statement in the form filed
with the Securities and Exchange Commission. We have also examined and relied
upon such records, documents and other instruments as in our judgment are
necessary or appropriate in order to express the opinions hereinafter set forth
and have assumed the genuineness of all signatures, the authenticity of all
documents submitted to us as originals, and the conformity to original documents
of all documents submitted to us or photostatic copies.
 
     Based upon the foregoing, we are of the opinion that the Common Stock, when
issued and delivered in the manner and on the terms described in the
Registration Statement (after the same is declared effectively by the Securities
and Exchange Commission), will be duly and validly issued, fully paid and
nonassessable.
 
     We hereby consent to the reference to our firm in the Registration
Statement under the "Legal Matters" and to the use of this opinion as an exhibit
to the Registration Statement.
 
                                          Sincerely,
 
                                          LANIER FORD SHAVER & PAYNE P.C.
