                             ISSUANCE AND EXECUTION
                            OF WARRANT CERTIFICATES

      Section II.1   ISSUANCE OF WARRANT CERTIFICATES.  Upon issuance, each
Warrant Certificate shall evidence one or more Warrants.  Each Warrant evidenced
thereby shall represent the right, subject to the provisions contained herein
and therein, to purchase one (1) share of Common Stock.

      Section II.2   FORM OF WARRANT CERTIFICATE.  The Warrant Certificates
(including the Form(s) of Exercise and Assignment to be set forth on the reverse
thereof) shall be in substantially the form set forth in Exhibit A hereto, shall
                                                         ---------              
be printed, lithographed or engraved on steel engraved borders (or in any other
manner determined by the officers executing such Warrant Certificates, with the
execution thereof by such officers conclusively evidencing such determination)
and may have such letters, numbers or other marks of identification and such
legends or endorsements placed thereon as may be required to comply with any law
or with any rule or regulation made pursuant thereto or with any rule or
regulation of any securities exchange on which the Warrants may be listed or as
may, consistently herewith, be determined by the officers executing such Warrant
Certificates, with the execution thereof by such officers conclusively
evidencing such determination.

      Section II.3   EXECUTION AND DELIVERY OF WARRANT CERTIFICATES. The Warrant
Certificates shall be executed on behalf of the Company by its Chairman and
Chief Executive Officer, its President or its Chief Financial Officer, under its
corporate seal reproduced thereon attested to by its Treasurer or Secretary. The
signature of any of these officers on the Warrant Certificates may be manual or
facsimile.

      Warrant Certificates evidencing the right to purchase a number of shares
of Common Stock having an aggregate par value not exceeding $700.00 (except as
provided in Sections 2.4, 3.3(b), 5.1 and 5.2) may be executed and delivered by
            ---------------------------------                                  
the Company upon the execution of this Warrant Agreement or from time to time
thereafter.  Subsequent to such original issuance of the Warrant Certificates,
the Company shall execute and deliver a Warrant Certificate only if the Warrant
Certificate is issued in exchange or in substitution for one or more previously
executed and delivered Warrant Certificates or in connection with their
transfer, as hereinafter provided.

     Each Warrant Certificate shall be dated the date of its execution by the
Company.

     No Warrant Certificate shall be entitled to any benefit under this
Agreement or be valid or obligatory for any purpose, and no Warrant evidenced
thereby shall be exercisable, until such Warrant Certificate has been duly
executed by the Company.  Such signature by the Company 

                                      -3-
<PAGE>
 
shall be conclusive evidence, and the only evidence, that the Warrant
Certificate so executed has been duly issued hereunder.

      Warrant Certificates bearing the manual or facsimile signatures of
individuals who were at the time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the delivery of such Warrant Certificates.

      Section II.4   TEMPORARY WARRANT CERTIFICATES.  Pending the preparation of
definitive Warrant Certificates, the Company may execute and deliver temporary
Warrant Certificates which are printed, lithographed, typewritten, mimeographed
or otherwise produced substantially of the tenor of the definitive Warrant
Certificates in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers
executing such Warrant Certificates may determine, with the execution thereof by
such officers conclusively evidencing such determination.

      If temporary Warrant Certificates are issued, the Company will cause
definitive Warrant Certificates to be prepared without unreasonable delay. After
the preparation of definitive Warrant Certificates, the temporary Warrant
Certificates shall be exchangeable for definitive Warrant Certificates upon
surrender of the temporary Warrant Certificates to the Company, without charge
to the Holder.  Upon surrender for cancellation of any one or more temporary
Warrant Certificates, the Company shall execute and deliver in exchange therefor
definitive Warrant Certificates representing the same aggregate number of
Warrants.  Until so exchanged, the temporary Warrant Certificates shall in all
respects be entitled to the same benefits under this Agreement as definitive
Warrant Certificates.

      Section II.5   PAYMENT OF TAXES.  The Company will pay all stamp taxes and
other duties, if any, arising out of or related to the execution and delivery of
this Agreement or the original issuance of the Warrant Certificates, under the
laws of the United States of America or any State or political subdivision

Certificate shall be registered upon the Warrant Register to be maintained by

      Section III.2   DURATION OF WARRANTS.  Any Warrant evidenced by a Warrant
Certificate may be exercised by the Holder thereof at any time and from time to
time during the period beginning on August 24, 1999, and at or before 5:00 p.m.
(Atlanta time) on February 24, 2008 (the "Expiration Date"), only upon the terms
                                          ---------------                       
and subject to the conditions set forth herein and in the applicable Warrant
Certificate.  Each Warrant not exercised at or before 5:00 p.m. (Atlanta time)
on the Expiration Date shall become void, and all rights of the Holder of the
Warrant Certificate evidencing such Warrant under this Agreement or otherwise
shall cease.

      Section III.3   EXERCISE OF WARRANTS.  (a)  During the period specified in
Section 3.2, any whole number of Warrants may be exercised by surrendering the
-----------                                                                   
Warrant Certificate evidencing such Warrants at the place or at the places set
forth in the Warrant Certificate, with the purchase form set forth in the
Warrant Certificate duly executed, accompanied by payment in full, in lawful
money of the United States of America, in cash or by certified check or official
bank check or by wire transfer in immediately available funds, of the Exercise
Price for each Warrant exercised. The date on which payment in full of the
Exercise Price for a Warrant and the duly executed and completed Warrant
Certificate are received by the Company shall be deemed to be the date on which
such Warrant is exercised.

      (b) As soon as practicable after the exercise of any Warrants, the Company
shall issue to or upon the order of the Holder of the Warrant Certificate
evidencing such Warrants, a certificate or certificates representing the number
of shares of Common Stock to which such Holder is entitled in such name or names
as may be directed by such Holder.  If fewer than all of the Warrants evidenced
by such Warrant Certificate are exercised, the Company shall execute and deliver
a new Warrant Certificate evidencing the number of Warrants remaining
unexercised.

      (c) The Company shall not be required to pay any stamp or other tax or
other governmental charge required to be paid in connection with any transfer
involved in the issuance of the Common Stock.  In the event that any such
transfer is involved, the Company shall not be required to issue or deliver any
shares of Common Stock until such tax or other charge shall have been paid or it
has been established to the Company's satisfaction that no such tax or other
charge is due.

      Section III.4   RESERVATION OF SHARES.  For the purpose of enabling it to
satisfy any obligation to issue shares of Common Stock upon exercise of
Warrants, the Company will, at all times through the close of business on the
Expiration Date, reserve and keep available, free from preemptive rights, out of
the aggregate of its authorized but unissued capital stock or its authorized and
issued capital stock held in its treasury, for the purpose of enabling it to
satisfy any obligation to issue Common Stock upon exercise of Warrants, the
maximum number of shares of Common Stock which may then be deliverable upon the
exercise of all outstanding Warrants.  The transfer agent for shares of Common
Stock of the Company (the "Transfer Agent") and every subsequent transfer agent
                           --------------                                      
for any shares of the Company's capital stock issuable upon the exercise of the
Warrants will be irrevocably authorized and directed at all times to reserve
such number of authorized shares as shall be required for such purpose.  The
Company 

                                      -5-
<PAGE>
 
will keep a copy of this Agreement on file with the Transfer Agent and with
every subsequent transfer agent for any shares of the Company's capital stock
issuable upon the exercise of the rights of purchase represented by the
Warrants. The Company will furnish such Transfer Agent a copy of all notices of
adjustments, and certificates related thereto, transmitted to each Holder
pursuant to Section 8.4. Before taking any action which would cause an
            ------------  
adjustment pursuant to Section 4.1 to the maximum number of shares of Common
                       -----------  
Stock deliverable upon the exercise of all outstanding Warrants pursuant to
Section 3.3, the Company shall cause to be authorized additional shares of
-----------
Common Stock such that the sum of such maximum number of shares of Common Stock
deliverable upon exercise of all outstanding Warrants and the number of shares
of Common Stock outstanding as of such date does not exceed the number of shares
of Common Stock authorized pursuant to the Company's Restated Articles of
Incorporation, as amended.

     The Company covenants that all shares of Common Stock issued upon exercise
of the Warrants will, upon issuance in accordance with the terms of this
Agreement, be fully paid and nonassessable and free from all taxes, liens,
charges and security interests created by or imposed upon the Company with
respect to the issuance and holding thereof.


                                   ARTICLE IV

                            OTHER TERMS OF WARRANTS

      Section IV.1     ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES
PURCHASABLE OR NUMBER OF WARRANTS.  The Exercise Price, the number of shares of
Common Stock purchasable upon the exercise of each Warrant and the number of
Warrants outstanding are subject to adjustment from time to time upon the
occurrence of the events enumerated in this Section 4.1.
                                            ----------- 

     (a) If the Company shall (i) pay a dividend in or make a distribution of
shares of its capital stock, whether shares of Common Stock or shares of its
capital stock of any other class, (ii) subdivide its outstanding shares of
Common Stock, (iii) combine its outstanding shares of Common Stock into a
smaller number of shares of Common Stock or (iv) issue any shares of its capital
stock in a reclassification of the Common Stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing corporation), the number of shares of Common Stock
purchasable upon exercise of each Warrant immediately prior thereto shall be
adjusted so that the Holder of each Warrant shall be entitled to receive the
kind and number of shares of Common Stock or other securities of the Company
which such Holder would have owned or have been entitled to receive after the
happening of any of the events described above, had such Warrant been exercised
immediately prior to the happening of such event or any record date with respect
thereto. An adjustment made pursuant to this paragraph (a) shall become
effective immediately after the effective date of such event, retroactive to
immediately after the record date, if any, for such event.

     (b) If the Company shall issue rights, options or warrants to all Holders
of its outstanding Common Stock, without any charge to such Holders, entitling
them to subscribe for 

                                      -6-
<PAGE>
 
or purchase shares of Common Stock at a price per share that is lower than the
Market Price per share of Common Stock (as defined in paragraph (e) below) at
the record date mentioned below, the number of shares of Common Stock thereafter
purchasable upon the exercise of each Warrant shall be determined by multiplying
the number of shares of Common Stock theretofore purchasable upon exercise of
each Warrant by a fraction, of which the numerator shall be (i) the number of
shares of Common Stock outstanding on the date of issuance of such rights,
options or warrants plus the number of additional shares of Common Stock offered
for subscription or purchase, and of which the denominator shall be (ii) the
number of shares of Common Stock outstanding on the date of issuance of such
rights, options or warrants plus the number of shares which the aggregate
offering price of the total number of shares of Common Stock so offered would
purchase at the Market Price per share of Common Stock at such record date. Such
adjustment shall be made whenever such rights, options or warrants are issued,
and shall become effective retroactive to immediately after the record date for
the determination of shareholders entitled to receive such rights, options or
warrants.

     (c) If the Company shall distribute to all Holders of its shares of Common
Stock evidence of its indebtedness or assets (excluding cash dividends or
distributions payable out of capital surplus and dividends or distributions
referred to in paragraph (a) above) or rights, options or warrants or
convertible or exchangeable securities containing the right to subscribe for or
purchase shares of Common Stock (excluding those referred to in paragraph (b)
above), then in each case the number of shares of Common Stock thereafter
purchasable upon the exercise of each Warrant shall be determined by multiplying
the number of shares of Common Stock theretofore purchasable upon the exercise
of each Warrant, by a fraction, of which the numerator shall be (i) the then
current Market Price per share of Common Stock (as defined in paragraph (e)
below) on the date of such distribution, and of which the denominator shall be
(ii) the then current Market Price per share of Common Stock less the then fair
value (as determined by the Board of Directors of the Company, whose
determination shall be conclusive) of the portion of the assets or evidence of
indebtedness so distributed or of such subscription rights, options or warrants
or convertible or exchangeable securities applicable to one (1) share of Common
Stock.  Such adjustment shall be made whenever any such distribution is made,
and shall become effective on the date of distribution retroactive to
immediately after the record date for the determination of shareholders entitled
to receive such distribution.

     (d) In the event of any capital reorganization or any reclassification of
the Common Stock (except as provided in paragraphs (a) through (c) above), any
Holder of Warrants upon exercise thereof shall be entitled to receive, in lieu
of the Common Stock to which he or she would have become entitled upon exercise
immediately prior to such reorganization or reclassification, the shares (of any
class or classes) or other securities or property of the Company that he or she
would have been entitled to receive at the same aggregate Exercise Price upon
such reorganization or reclassification if his or her Warrants had been
exercised immediately prior thereto.

     (e) For the purpose of any computation under paragraphs (b) and (c) of this
Section 4.1, the current or closing Market Price per share of Common Stock at
-----------                                                                  
any date shall be deemed to be the average of the daily closing prices for the
twenty (20) consecutive trading days before 

                                      -7-
<PAGE>
 
the date of such computation. The closing price for each day shall be the last
sale price for such day, in either case as reported in the principal
consolidated transaction reporting system with respect to securities listed or
admitted to trading on the New York Stock Exchange (the "NYSE") or if the Common
                                                         ----   
Stock is not listed on the NYSE, then on the principal United States national
securities exchange on which the Common Stock is listed or quoted. If the Common
Stock is not listed or quoted on any United States national securities exchange,
then the current or closing market price per share of Common Stock shall be
determined by the Board of Directors of the Company in good faith.

     (f)  Whenever the number of shares of Common Stock purchasable upon the
exercise of each Warrant is adjusted as herein provided, the Exercise Price
payable upon the exercise of each Warrant shall be adjusted by multiplying such
Exercise Price immediately prior to such adjustment by a fraction, of which the
numerator shall be the number of shares purchasable upon the exercise of each
Warrant immediately prior to such adjustment, and of which the denominator shall
be the number of shares so purchasable immediately thereafter.

     (g)  The Company may elect, on or after the date of any adjustment required
by paragraphs (a) through (d) of this Section 4.1, to adjust the number of
                                      -----------                         
Warrants in substitution for an adjustment in the number of shares of Common
Stock purchasable upon the exercise of a Warrant. Each of the Warrants
outstanding after such adjustment of the number of Warrants shall be exercisable
for the same number of shares of Common Stock as immediately prior to such
adjustment. Each Warrant held of record prior to such adjustment of the number
of Warrants shall become that number of Warrants (calculated to the nearest
hundredth) obtained by dividing the Exercise Price in effect prior to adjustment
of the Exercise Price by the Exercise Price in effect after adjustment of the
Exercise Price. The Company shall notify the Holders of Warrants, in the same
manner as provided in the first paragraph of Section 8.4, of its election to
                                             -----------                    
adjust the number of Warrants, indicating the record date for the adjustment,
and, if known at the time, the amount of the adjustment to be made. This record
date may be the date on which the Exercise Price is adjusted or any day
thereafter. Upon each adjustment of the number of Warrants pursuant to this
paragraph (g) the Company shall, as promptly as practicable, cause to be
distributed to Holders of record of Warrants on such record date Warrant
Certificates evidencing, subject to paragraph (h), the additional Warrants to
which such Holders shall be entitled as a result of such adjustment, or, at the
option of the Company, shall cause to be distributed to such Holders of record
in substitution and replacement for the Warrant Certificates held by such
Holders prior to the date of adjustment, and upon surrender thereof, new Warrant
Certificates evidencing all the Warrants to be executed, issued and registered
in the manner specified in Section 5.1 (and which may bear, at the option of the
                           -----------                                          
Company, the adjusted Exercise Price) and shall be registered in the names of
the Holders of record of Warrant Certificates on the record date specified in
the notice.

     (h)  The Company shall not be required to issue fractions of Warrants on
any distribution of Warrants to Holders of Warrant Certificates pursuant to
paragraph (g) or to distribute Warrant Certificates that evidence fractional
Warrants. In lieu of such fractional Warrants, there shall be paid to the
registered Holders of the Warrant Certificates with regard to which such
fractional Warrants would otherwise be issuable, an amount in cash equal to the

                                      -8-
<PAGE>
 
same fraction of the current market value of a full Warrant on the trading day
immediately prior to the date on which such fractional Warrant could have been
otherwise issuable (the "Valuation Date").  For purposes of this paragraph (h),
                         --------------                                        
the current market value of a Warrant shall be the aggregate closing Market
Price on the Valuation Date (determined as set forth in paragraph (e)) of all
shares of Common Stock issuable upon exercise of one Warrant plus the fair value
(as determined by the Board of Directors of the Company, whose determination
shall be conclusive) of any other assets or securities purchasable upon exercise
of one Warrant less the Exercise Price of one Warrant.

     (i) Notwithstanding any adjustment pursuant to Section 4.1 in the number of
                                                    -----------                 
shares of Common Stock purchasable upon the exercise of a Warrant, the Company
shall not be required to issue fractions of shares of Common Stock upon exercise
of the Warrants or to distribute certificates which evidence fractional shares.
In lieu of fractional shares, there shall be paid to the registered Holders of
Warrant Certificates at the time such Warrant Certificates are exercised as
herein provided an amount in cash equal to the same fraction of the current
market value of one (1) share of Common Stock. For purposes of this paragraph
(i), the current market value of one (1) share of Common Stock shall be the
closing Market Price (determined as set forth in paragraph (e)) of one (1) share
of Common Stock for the trading day immediately prior to the date of such
exercise.

                                   ARTICLE V

                     REGISTRATION, EXCHANGE, TRANSFER AND
                     SUBSTITUTION OF WARRANT CERTIFICATES

      Section V.1   REGISTRATION, EXCHANGE AND TRANSFER OF WARRANT CERTIFICATES.
The Company shall keep, at its principal executive offices, books in which,
subject to such reasonable regulations as it may prescribe, it shall register
Warrant Certificates and transfers of outstanding Warrants (the "Warrant
                                                                 -------
Register").
--------   

     Upon surrender at the principal executive offices of the Company of Warrant
Certificates properly endorsed or accompanied by appropriate instruments of
transfer and accompanied by written instructions for transfer or exchange, all
in form satisfactory to the Company, such Warrant Certificates may be exchanged
for other Warrant Certificates or may be transferred in whole or in part;
provided, however, that Warrant Certificates issued in exchange for or upon
--------  -------                                                          
transfer of surrendered Warrant Certificates shall evidence the same aggregate
number of Warrants as the Warrant Certificates so surrendered. No service charge
shall be made for any exchange or transfer of Warrant Certificates, but the
Company may require payment of a sum sufficient to cover any stamp or other tax
or governmental charge that may be imposed in connection with any such exchange
or transfer. Whenever any Warrant Certificates are so surrendered for exchange
or transfer, the Company shall execute and deliver to the Person or Persons
entitled thereto a Warrant Certificate or Warrant Certificates as so requested.
The Company shall not be required to effect any exchange or transfer which would
result in the issuance of a Warrant Certificate evidencing a fraction of a
Warrant or a number of full Warrants and a fraction of a Warrant. All Warrant
Certificates issued upon any exchange or transfer of 

                                      -9-
<PAGE>
 
Warrant Certificates shall evidence the same obligations, and be entitled to the
same benefits under this Agreement, as the Warrant Certificates surrendered for
such exchange or transfer.

     Section V.2   MUTILATED, DESTROYED, LOST OR STOLEN WARRANT CERTIFICATES.
If any mutilated Warrant Certificate is surrendered to the Company, the Company
shall execute and deliver in exchange therefor a new Warrant Certificate of like
tenor and bearing a number not contemporaneously outstanding. If there shall be
delivered to the Company (i) evidence to its satisfaction of the destruction,
loss or theft of any Warrant Certificate and of the ownership thereof and (ii)
such security or indemnity as may be required by it to save the Company and any
agent thereof harmless, then, in the absence of notice to the Company that such
Warrant Certificate has been acquired by a bona fide purchaser, the Company
shall execute and deliver, in lieu of any such destroyed, lost or stolen Warrant
Certificate, a new Warrant Certificate of like tenor and bearing a number not
contemporaneously outstanding.  Upon the issuance of any new Warrant Certificate
under this Section 5.2, the Company may require the payment of a sum sufficient
           -----------                                                         
to cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses connected therewith. Every new Warrant
Certificate issued pursuant to this Section 5.2 in lieu of any destroyed, lost
                                    -----------                               
or stolen Warrant Certificate shall evidence an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Warrant
Certificate shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Agreement equally and proportionately with any and all
other Warrant Certificates duly issued hereunder. The provisions of this Section
                                                                         -------
5.2 are exclusive and shall preclude (to the extent lawful) all other rights and
---                                                                             
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Warrant Certificates.

     Section V.3   PERSONS DEEMED OWNERS.  Prior to due presentment of a
Warrant Certificate for registration of transfer, the Company and all other
Persons may treat the Holder as the owner thereof for any purpose and as the
Person entitled to exercise the rights represented by the Warrants evidenced
thereby, any notice to the contrary notwithstanding.

     Section V.4   CANCELLATION OF WARRANT CERTIFICATES.  Any Warrant
Certificate surrendered to the Company for exchange, transfer or exercise of the
Warrants evidenced thereby shall be promptly canceled by it and shall not be
reissued and, except as expressly permitted by this Agreement, no Warrant
Certificate shall be issued hereunder in lieu or in exchange thereof. The
Company shall promptly cancel any Warrant Certificates previously issued
hereunder which the Company may have acquired in any manner whatsoever.

                      OF HOLDERS OF WARRANT CERTIFICATES

      Section VI.1   NO RIGHTS AS SHAREHOLDER CONFERRED BY WARRANTS OR WARRANT
CERTIFICATES.  No Warrant Certificate or Warrant evidenced thereby shall entitle
the Holder thereof to any of the rights of a shareholder, including, without
limitation, the right to receive dividends.

      Section VI.2   HOLDER OF WARRANT CERTIFICATE MAY ENFORCE RIGHTS.
Notwithstanding any of the provisions of this Agreement, any Holder of any
Warrant Certificate, without the consent of any shareholder or the Holder of any
other Warrant Certificate, may, on its own behalf and for its own benefit,
enforce, and may institute and maintain any suit, action or proceeding against
the Company suitable to enforce or otherwise in respect of its right to exercise
the Warrant or Warrants evidenced by his or her Warrant Certificate in the
manner provided in the Warrant Certificates and in this Agreement.

     Section VII.1  CONSOLIDATIONS AND MERGERS OF THE COMPANY AND SALES, LEASES
AND CONVEYANCES PERMITTED SUBJECT TO CERTAIN CONDITIONS.  The Company may
consolidate with, or sell or convey all or substantially all of its assets to,
or merge with or into any other corporation, provided that in any such case,
either the Company shall be the continuing corporation, or the corporation (if
other than the Company) formed by such consolidation or into which the Company
is merged or the corporation which acquired by purchase or conveyance all or
substantially all of the assets of the Company shall expressly assume the
obligations of the Company hereunder.

     Section VII.2  RIGHTS AND DUTIES OF SUCCESSOR CORPORATION.  In case of any
such consolidation, merger, sale, lease or conveyance and upon any such
assumption by the successor corporation, such successor corporation shall
succeed to and be substituted for the Company, with the same effect as if it had
been named herein, and the predecessor corporation, except in the event of a
lease, shall be relieved of any further obligation under this Agreement and the
Warrants. Such successor corporation thereupon may cause to be signed, and may
issue either in its own name or in the name of the Company, any or all of the
shares of Common Stock issuable pursuant to the terms hereof.

     Section VII.3  AMENDMENT.  This Agreement may be amended by the parties
hereto, without the consent of the Holder of any Warrant Certificate, for the
purpose of curing any ambiguity, or curing, correcting or supplementing any
defective provision contained herein, or making such provisions in regard to
matters or questions arising under this Agreement as the Company may deem
necessary or desirable; provided, however, that such action shall not adversely
                        --------  -------                                      
affect the interests of the Holders of the Warrant Certificates in any material
respect. Any amendment or supplement to this Agreement or the Warrants that has
a material adverse effect on the interests of Holders of any series of Warrants
shall require the written consent of the Holders of a majority of the then
outstanding Warrants of such series. The consent of each Holder of a Warrant
affected shall be required for any amendment pursuant to which the Exercise
Price would be increased or the number of shares of Common Stock purchasable
upon exercise of Warrants would be decreased.

     Section VII.4  NOTICES TO WARRANTHOLDERS. Upon any adjustment of the
number of shares purchasable upon exercise of each Warrant, the Exercise Price
or the number of Warrants outstanding pursuant to Section 4.1, the Company
                                                  -----------  
within ten (10) Business Days thereafter shall cause to be given to each of the
Holders of the Warrant Certificates written notice of such adjustments, together
with a copy of a certificate of the Chief Financial Officer of the Company
setting forth the Exercise Price and either the number of shares of Common Stock
and other securities or assets purchasable upon exercise of each Warrant or the
additional number of Warrants to be issued for each previously outstanding
Warrant, as the case may be, after such adjustment and setting forth in

          ------------------- 
or distribution (including sales pursuant to Rule 144) of equity securities of
the Company, or any securities convertible into or exchangeable or exercisable
for such securities, during the 7 days prior to (provided that such Holder
receives a notice from the Company of the commencement of such 7-day period) and
the 90-day period beginning on the effective date of any underwritten offering

     6.   Indemnification; Contribution.
          ----------------------------- 

     (a)  Indemnification by the Company.  The Company agrees to indemnify and
          ------------------------------                                      
hold harmless each Holder and the beneficial owners, officers and directors and
each Person, if any, who controls each Holder within the meaning of Section 15
of the Securities Act as follows:

          (i)    against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to which each Holder, or any beneficial owner,
     officer, director or controlling Person may become subject under the
     Securities Act or otherwise (A) that arise out of or are based upon any
     untrue statement or alleged untrue statement of a material fact contained
     in the Shelf Registration Statement or any amendment thereto, or 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 or (B) that arise out of or are based upon any untrue statement
     or alleged untrue statement of a material fact contained in any Shelf
     Prospectus or any amendment or supplement thereto, or the omission or
     alleged omission to state therein a material fact necessary in order to
     make the statements therein, in the light of the circumstances under which
     they were made, not misleading;

          (ii)   against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or alleged untrue statement
     or any omission or alleged omission, if such settlement is effected with
     the written consent of the Company; and

          (iii)  subject to the limitations set forth in Section 6(c), against
     any and all expense whatsoever, as incurred (including reasonable fees and
     disbursements of counsel), reasonably incurred in investigating, preparing
     or defending against any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, in each case whether
     or not a party, or any claim whatsoever based upon any such untrue
     statement or alleged untrue statement or omission or alleged omission, to
     the extent that any such expense is not paid under subparagraph (i) or (ii)
     above;

provided, however, that the indemnity provided pursuant to this Section 6(a)
--------  -------                                                           
shall not apply with respect to any loss, liability, claim, damage or expense
that arises out of or are based upon any untrue statement or alleged untrue
statement or omission or alleged omission made in reliance upon and in
conformity with written information furnished to the Company by any Holder (i)
expressly for use in the Shelf Registration Statement or any amendment thereto,
or the Shelf Prospectus or any amendment or supplement thereto or (ii) pursuant
to any representation, warranty or other statement contained in the Contribution
Agreement or any admission amendment to the Partnership Agreement.

     (b)  Indemnification by the Holders.   Each Holder severally agrees to
          ------------------------------                                   
indemnify and hold harmless the Company, and each of its respective directors
and officers (including each director

                                     -11-
<PAGE>
 
and officer of the Company who signed the Shelf Registration Statement), and
each Person, if any, who controls the Company within the meaning of Section 15
of the Securities Act, to the same extent as the indemnity contained in Section
6(a) hereof, but only insofar as such loss, liability, claim, damage or expense
arises out of or is based upon any untrue statement or alleged untrue statement
or omission or alleged omission made in the Shelf Registration Statement or any
amendment thereto, or the Shelf Prospectus or any amendment or supplement
thereto, in reliance upon and in conformity with written information furnished
to the Company by such Holder expressly for use therein. In no event, however,
shall the liability of a Holder exceed the cumulative net proceeds received by
such Holder from any offering made in connection with a Shelf Registration
Statement.

     (c)  Conduct of Indemnification Proceedings. Each indemnified party shall
          --------------------------------------
give reasonably prompt notice to each indemnifying party of any action or
proceeding commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party (i) shall not relieve
it from any liability which it may have under the indemnity agreement provided
in Section 6(a) or (b) above, unless and to the extent it did not otherwise
learn of such action and the lack of notice by the indemnified party materially
prejudices the indemnifying party or results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) shall not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided under Section 6(a) or
(b) above. After receipt of such notice, the indemnifying party shall be
entitled to participate in and, to the extent it shall wish, jointly with any
other indemnifying party so notified, to assume the defense of such action or
proceeding at such indemnifying party's own expense with counsel chosen by such
indemnifying party and approved by the indemnified party, which approval shall
not be unreasonably withheld; provided, however, that, if the defendants in any
                              --------  -------
such action or proceeding include both the indemnified party and the
indemnifying party and the indemnified party reasonably determines, upon advice
of counsel, that a conflict of interest exists or that there may be legal
defenses available to it or other indemnified parties that are different from or
in addition to those available to the indemnifying party, then the indemnified
party shall be entitled to separate counsel (which shall be limited to a single
law firm), the reasonable fees and expenses of which shall be paid by the
indemnifying party. If the indemnifying party does not assume the defense of any
such action or proceeding, after having received the notice referred to in the
first sentence of this paragraph, the indemnifying party will pay the reasonable
fees and expenses of counsel (which shall be limited to a single law firm) for
the indemnified party. In such event, however, the indemnifying party will not
be liable for any settlement effected without the written consent of such
indemnifying party. If the indemnifying party assumes the defense of any such
action or proceeding in accordance with this paragraph, such indemnifying party
shall not be liable for any fees and expenses of counsel for the indemnified
party incurred thereafter in connection with such action or proceeding, except
as set forth in the proviso in the second sentence of this Section 6(c).

     (d)  Contribution. In order to provide for just and equitable contribution
          ------------   
in circumstances in which the indemnity agreement provided for in this Section 6
is for any reason held to be unenforceable although applicable in accordance
with its terms, the Company and the selling Holders shall contribute to the
aggregate losses, liabilities, claims, damages and expenses of the nature
contemplated by such indemnity agreement incurred by the Company and the selling
Holders,

                                     -12-
<PAGE>
 
in such proportion as is appropriate to reflect the relative fault of and
benefits to the Company on the one hand and the selling Holders on the other (in
such proportion that the selling Holders are severally, not jointly, responsible
for the balance), in connection with the statements or omissions which resulted
in such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations. The relative benefits to the indemnifying
party and indemnified parties shall be determined by reference to, among other
things, the total proceeds received by the indemnifying party and indemnified
parties in connection with the offering to which such losses, claims, damages,
liabilities or expenses relate. The relative fault of the indemnifying party and
indemnified parties shall be determined by reference to, among other things,
whether the action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or
the indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action.

     The parties hereto agree that it would not be just or equitable if
contribution pursuant to this Section 6(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 6(d), a Holder shall not be
required to contribute any amount in excess of the amount by which the total
price at which the Shelf Registrable Securities of such Holder were offered to
the public exceeds the amount of any damages which such Holder would otherwise
have been required to pay by reason of such untrue statement or omission.

     Notwithstanding the foregoing, no Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.  For purposes of this Section 6(d), each Person,
if any, who controls any Holder within the meaning of Section 15 of the
Securities Act and beneficial owners, directors and officers of any Holder shall
have the same rights to contribution as any member of the Holders, and each
director of the Company, each officer of the Company who signed the Shelf
Registration Statement, and each Person, if any, who controls the Company within
the meaning of Section 15 of the Securities Act shall have the same rights to
contribution as the Company.

     (e)  In the event any sale pursuant to a Shelf Registration is an
underwritten offering, then the Company agrees to indemnify and hold harmless
each underwriter of Shelf Registrable Securities to the same extent and on
substantially similar terms as the Company's indemnification of the members of
the Holders as set forth in Section 6(a) above.

      7.  Rule 144 Sales.
          -------------- 

     (a)  Compliance. The Company covenants that, so long as it is subject to
          ---------- 
the reporting requirements of the Exchange Act, it will file the reports
required to be filed by it under the

                                     -13-

Exchange Act so as to enable the Holders to sell Shelf Registrable Securities
pursuant to Rule 144 under the Securities Act.

     (b)  Cooperation with the Holders. In connection with any sale, transfer or
          ---------------------------- 
other disposition by a Holder of any Shelf Registrable Securities pursuant to
Rule 144 under the Securities Act, the Company shall cooperate with such Holder
to facilitate the timely preparation and delivery of certificates representing
Shelf Registrable Securities to be sold and not bearing any Securities Act
legend, and enable certificates for such Shelf Registrable Securities to be for
such number of shares as such Holder may reasonably request at least two
business days prior to any sale of Shelf Registrable Securities.

days after being deposited in the mail, postage prepaid, if mailed; when

the time delivered if delivered by an air courier guaranteeing overnight

     (c)  No Assignment.  This Agreement shall inure to the benefit of and be

binding upon the parties hereto and, where applicable, their successors and
permitted assigns.  No party to this Agreement may assign or delegate all or any
portion of its rights, obligations, or liabilities under this Agreement without

transferred to (a) any transferee of such Shelf Registrable Securities who
acquires at least 25% of the total number of Shelf Registrable Securities
(adjusted for stock splits and consolidations after the date hereof) or (b) an
affiliate of such Holder; provided further that the transferring Holder shall
                          -------- -------                                   
give the Company written notice prior to the time of such transfer stating the
name and address of the transferee and identifying the number of Shelf
Registrable Securities so transferred.   Nothing expressed or implied herein is
intended or shall be construed to confer upon or give to any third party any
rights or remedies by virtue hereof.

     (d)  Third Party Beneficiaries. There shall be no third party beneficiaries
          -------------------------

when so executed shall be deemed to be an original and all of which taken

Agreement in accordance with the terms and conditions of this Agreement in any
court of the United States or any State thereof having jurisdiction.
