                            ----------------------


          THIS REGISTRATION AGREEMENT dated as of September 18, 1997 is made by
and among CII Technologies, Inc., a Delaware corporation (the "Company"), the
                                                               -------       
Persons listed on Schedule A attached hereto (the "CHS Group"), the Persons
                  ----------                       ---------               
listed on Schedule B attached hereto (the "TCW/Crescent Group"), the Persons
          ----------                       ------------------               
listed on Schedule C attached hereto (the "Executive Stockholders"), and the
          ----------                       ----------------------           
Persons listed on Schedule D attached hereto (the "Other Investors"). Unless
                  ----------                       ---------------          
otherwise provided in this Agreement, capitalized terms used herein shall have
the meanings set forth in Section 9 hereof.
                          ---------        

          NOW, THEREFORE, in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties to this Agreement hereby agree as
follows:

          1.   Demand Registrations.
               -------------------- 

          (a)  Requests for Registration.  At any time the holders of a majority
              -------------------------                                        
of the CHS Registrable Securities may request registration under the Securities
Act of all or part of their Registrable Securities on Form S-1 or any similar
long-form registration ("Long-Form Registrations") or, if available, on Form S-2
                         -----------------------                                
or S-3 or any similar short-form registration ("Short-Form Registrations").  All
                                                ------------------------        
registrations requested pursuant to this Section 1(a) are referred to herein as
                                         ------------                          
"Demand Registrations."  Each request for a Demand Registration shall specify
 --------------------                                                        
the approximate number of CHS Registrable Securities requested to be registered
and the anticipated per share price range for such offering.  Within ten days
after receipt of any such request, the Company shall give written notice of such
requested registration to all other holders of Registrable Securities and,
subject to Section 1(d) below, will include in such registration all Registrable
           ------------                                                         
Securities with respect to which the Company has received written requests for
inclusion therein within 15 days after the receipt of the Company's notice.

          (b)  Long-Form Registrations.  The holders of a majority of the CHS
              -----------------------                                       
Registrable Securities shall be entitled to request unlimited Long-Form
Registrations in which the Company will pay all Registration Expenses (as
defined below in Section 5).  All Long-Form Registrations shall be underwritten
                 ---------                                                     
registrations.

          (c)  Short-Form Registrations.  In addition to the Long-Form
               ------------------------                               
Registrations provided pursuant to Section 1(b), the holders of a majority of
                                   ------------                              
the CHS Registrable Securities shall be entitled to request an unlimited number
of Short-Form Registrations in which the Company will pay all Registration
Expenses.  Demand Registrations will be Short-Form Registrations whenever the
Company is permitted to use any applicable short form. After the Company has
become subject to the reporting requirements of the Securities Exchange Act of
1934, as amended, the Company shall use its best efforts to make Short-Form
Registrations on Form S-3 available for the sale of

 
Registrable Securities.  All Short-Form Registrations shall be underwritten
registrations, unless otherwise agreed to by the Company.

          (d)  Priority on Demand Registrations.  The Company will not include
               --------------------------------
in any Demand Registration any securities which are not Registrable Securities
without the prior written consent of the holders of a majority of the
Registrable Securities included in such registration. If a Demand Registration
is an underwritten offering and the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Securities and, if
permitted hereunder, other securities requested to be included in such offering
exceeds the number of Registrable Securities and other securities, if any, which
can be sold therein without adversely affecting the marketability of the
offering, the Company will include in such registration (i) first, the number of
                                                            -----               
Registrable Securities requested to be included in such registration which in
the opinion of such underwriters can be sold without adverse effect, pro rata
among the respective holders thereof on the basis of the number of Registrable
Securities owned by each such holder and (ii) second, other securities requested
                                              ------                            
to be included in such Demand Registration, pro rata among the holders of such
securities on the basis of the number of such securities owned by each such
holder.

          (e)  Restrictions on Demand Registrations.  The Company will not be
               ------------------------------------                          
obligated to effect any Demand Registration within six months after the
effective date of a previous Demand Registration.  The Company may postpone for
up to six months (from the date of the request) the filing or the effectiveness
of a registration statement for a Demand Registration if the Company's board of
directors believes that such Demand Registration would reasonably be expected to
have an adverse effect on any proposal or plan by the Company or any of its
Subsidiaries to engage in any acquisition of assets (other than in the ordinary
course of business) or any merger, consolidation, tender offer or similar
transaction; provided, however, that in such event, the holders of Registrable
Securities initially requesting such Demand Registration will be entitled to
withdraw such request and, if such request is withdrawn, such Demand
Registration will not count as one of the permitted Demand Registrations
hereunder and the Company will pay all Registration Expenses in connection with
such registration.

          (f)  Selection of Underwriters.  The holders of a majority of the
               -------------------------                                   
Registrable Securities included in any Demand Registration shall have the right
to select the investment banker(s) and manager(s) to administer the offering,
subject to the Company's approval which will not be unreasonably withheld.

          2.   Piggyback Registrations.
               ----------------------- 

          (a)  Right to Piggyback.  Whenever the Company proposes to register
               ------------------
any of its equity securities under the Securities Act (other than (i) pursuant
to a Demand Registration or (ii) pursuant to a registration on Form S-4 or S-8
or any successor or similar forms) and the registration form to be used may be
used for the registration of Registrable Securities (a "Piggyback
                                                        ---------
Registration"), whether or not for sale for its own account, the Company will
- - ------------
give prompt written notice to all holders of Registrable Securities of its
intention to effect such a registration and will include in such registration
all Registrable Securities with respect to which the Company has

                                     - 2 -

 
received written requests for inclusion therein within 15 days after the receipt
of the Company's notice.

          (b)  Piggyback Expenses.  The Registration Expenses of the holders of
               ------------------                                              
Registrable Securities will be paid by the Company in all Piggyback
Registrations.

          (c)  Priority on Primary Registrations. If a Piggyback Registration is
               ---------------------------------                                
an underwritten primary registration on behalf of the Company, and the managing
underwriters advise the Company in writing (with a copy to each party hereto
requesting registration of Registrable Securities) that in their opinion the
number of securities requested to be included in such registration exceeds the
number which can be sold in such offering without adversely affecting the
marketability of such offering, the Company will include in such registration
(i) first, the securities the Company proposes to sell, (ii) second, the
    -----                                                    ------     
Registrable Securities requested to be included in such registration, pro rata
among the holders thereof on the basis of the number of Registrable Securities
owned by each such holder, and (iii) third, other securities requested to be
                                     -----                                  
included in such registration pro rata among the holders of such securities on
the basis of the number of such securities owned by each such holder.

          (d)   Priority on Secondary Registrations.  If a Piggyback
Registration is an underwritten secondary registration on behalf of holders of
the Company's securities (it being understood that secondary registrations on
behalf of holders of Registrable Securities are addressed in Section 1 above
                                                             ---------   
rather than this Section 2(d)), and the managing underwriters advise the Company
                 -------------
in writing that in their opinion the number of securities requested to be
included in such registration exceeds the number which can be sold in such
offering without adversely affecting the marketability of the offering, the
Company will include in such registration (i) first, the securities requested to
                                              -----
be included therein by the holders requesting such registration, (ii) second,
                                                                      ------
the Registrable Securities requested to be included in such registration, pro
rata among the holders of such Registrable Securities on the basis of the number
of Registrable Securities owned by each such requesting holder, and (iii) third,
other securities requested to be included in such registration.

          (e)  Selection of Underwriters.  If any Piggyback Registration is an
               -------------------------                                      
underwritten offering, the selection of the investment banker(s) and manager(s)
for the offering must be approved by the holders of a majority of the
Registrable Securities included in such Piggyback Registration, which approval
shall not be unreasonably withheld.

          (f)  Other Registrations.  If the Company has previously filed a
               -------------------                                        
registration statement with respect to Registrable Securities pursuant to
                                                                         
Section 1 or pursuant to this Section 2, and if such previous registration has
- - ---------                     ---------                                       
not been withdrawn or abandoned, the Company will not file or cause to be
effected any other registration of any of its equity securities or securities
convertible or exchangeable into or exercisable for its equity securities under
the Securities Act (except on Form S-4 or S-8 or any successor form), whether on
its own behalf or at the request of any holder or holders of such securities,
until a period of at least six months has elapsed from the effective date of
such previous registration.

                                      -3-

 
          3.   Holdback Agreements.
               ------------------- 

          (a)  Each holder of Registrable Securities agrees not to effect any
public sale or distribution (including sales pursuant to Rule 144) of equity
securities of the Company, or any securities, options or rights convertible into
or exchangeable or exercisable for such securities, during the seven days prior
to and the 180-day period beginning on the effective date of any underwritten
public offering of the Company's equity securities (including Demand and
Piggyback Registrations) (except as part of such underwritten registration),
unless the underwriters managing the registered public offering otherwise agree.

          (b)  The Company (i) agrees not to effect any public sale or
distribution of its equity securities, or any securities convertible into or
exchangeable or exercisable for such securities, during the seven days prior to
and during the 180-day period beginning on the effective date of any
underwritten public offering of the Company's equity securities (including
Demand and Piggyback Registrations) (except as part of such underwritten
registration or pursuant to registrations on Form S-4 or S-8 or any successor
form), unless the underwriters managing the registered public offering otherwise
agree and (ii) shall cause each holder of its Common Stock, or any securities
convertible into or exchangeable or exercisable for Common Stock, purchased from
the Company at any time after the date of this Agreement (other than in a
registered public offering) to agree not to effect any public sale or
distribution (including sales pursuant to Rule 144) of any such securities
during such period (except as part of such underwritten registration, if
otherwise permitted), unless the underwriters managing the registered public
offering otherwise agree.

          4.   Registration Procedures.  Whenever the holders of Registrable
               -----------------------
Securities have requested that any Registrable Securities be registered pursuant
to this Agreement, the Company will use its best efforts to effect the
registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof and pursuant thereto the Company will as
expeditiously as possible:

          (a)  prepare and (within 60 days after the end of the period within
which requests for registration may be given to the Company) file with the
Securities and Exchange Commission a registration statement with respect to such
Registrable Securities and thereafter use its best efforts to cause such
registration statement to become effective (provided that before filing a
registration statement or prospectus or any amendments or supplements thereto,
the Company will furnish to the counsel selected by the holders of a majority of
the Registrable Securities covered by such registration statement copies of all
such documents proposed to be filed, which documents will be subject to review
of such counsel);

          (b)  prepare and file with the Securities and Exchange Commission such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to keep such registration
statement effective for a period of either (i) not less than six months (subject
to extension pursuant to Section 7(b)) or, if such registration statement
                         ------------                                    
relates to an underwritten offering, such longer period as in the opinion of
counsel for the underwriters a prospectus is required by law to be delivered in
connection with sales of Registrable Securities by an underwriter or dealer or
(ii) such shorter period as will terminate when all of the

                                     - 4 -

 
securities covered by such registration statement have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof set forth in such registration statement (but in any event not before
the expiration of any longer period required under the Securities Act), and to
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such registration statement until such time as all
of such securities have been disposed of in accordance with the intended methods
of disposition by the seller or sellers thereof set forth in such registration
statement;

          (c)  furnish to each seller of Registrable Securities such number of
copies of such registration statement, each amendment and supplement thereto,
the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as such seller may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such seller;

          (d)  use its best efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions as
any seller reasonably requests and do any and all other acts and things which
may be reasonably necessary or advisable to enable such seller to consummate the
disposition in such jurisdictions of the Registrable Securities owned by such
seller (provided that the Company will not be required to (i) qualify generally
to do business in any jurisdiction where it would not otherwise be required to
qualify but for this subsection, (ii) subject itself to taxation in any such
jurisdiction or (iii) consent to general service of process in any such
jurisdiction);

          (e)  notify each seller of such Registrable Securities, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, upon discovery that, or upon the discovery of the happening of
any event as a result of which, the prospectus included in such registration
statement contains an untrue statement of a material fact or omits any fact
necessary to make the statements therein not misleading in the light of the
circumstances under which they were made, and, at the request of any such
seller, the Company will prepare and furnish to such seller a reasonable number
of copies of a supplement or amendment to such prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus will
not contain an untrue statement of a material fact or omit to state any fact
necessary to make the statements therein not misleading in the light of the
circumstances under which they were made;

          (f)  cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed and, if not so listed, to be listed on a securities exchange or the NASD
automated quotation system and, if listed on the NASD automated quotation
system, use its best efforts to secure designation of all such Registrable
Securities covered by such registration statement as a NASDAQ "national market
system security" within the meaning of Rule 11Aa2-1 of the Securities and
Exchange Commission or, failing that, to secure NASDAQ authorization for such
Registrable Securities and, without limiting the generality of the foregoing, to
arrange for at least two market makers to register as such with respect to such
Registrable Securities with the NASD;

                                     - 5 -

 
          (g)  provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (h)  enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities (including, without limitation, effecting a stock split
or a combination of shares);

          (i)  make available for inspection by any seller of Registrable
Securities, any underwriter participating in any disposition pursuant to such
registration statement and any attorney, accountant or other agent retained by
any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement;

          (j)  otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least 12 months beginning with the
first day of the Company's first full calendar quarter after the effective date
of the registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

          (k)  permit any holder of Registrable Securities which holder, in its
sole and exclusive judgment, might be deemed to be an underwriter or a
controlling person of the Company, to participate in the preparation of such
registration or comparable statement and to require the insertion therein of
material, furnished to the Company in writing, which in the reasonable judgment
of such holder and its counsel should be included;

          (l)  in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any securities included in such registration statement for sale in any
jurisdiction, the Company will use its reasonable best efforts promptly to
obtain the withdrawal of such order;

          (m)  use its reasonable best efforts to cause such Registrable
Securities covered by such registration statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary
to enable the sellers thereof to consummate the disposition of such Registrable
Securities;

          (n)  obtain a cold comfort letter from the Company's independent
public accountants in customary form and covering such matters of the type
customarily covered by cold comfort letters, which letter shall be addressed to
the underwriters; and use its reasonable best efforts

                                     - 6 -

 
to cause such cold comfort letter to also be addressed to the holders of such
Registrable Securities; and

          (o)  obtain an opinion from the Company's outside counsel in customary
form and covering such matters of the type customarily covered by such opinions,
which opinion shall be addressed to the underwriters and the holders of such
Registrable Securities.

The Company may require each seller of Registrable Securities as to which any
registration is being effected to furnish the Company such information regarding
such seller and the distribution of such securities as the Company may from time
to time reasonably request in writing.

          5.   Registration Expenses.
               --------------------- 

          (a)  All expenses incident to the Company's performance of or
compliance with this Agreement, including, without limitation, all registration
and filing fees, fees and expenses of compliance with securities or blue sky
laws, printing expenses, messenger and delivery expenses, fees and disbursements
of custodians and fees and disbursements of counsel for the Company and all
independent certified public accountants, underwriters (excluding discounts and
commissions) and other Persons retained by the Company (all such expenses being
herein called "Registration Expenses"), will be borne as provided in this
               ---------------------                                     
Agreement, except that the Company will, in any event, pay its internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of any annual
audit or quarterly review, the expense of any liability insurance and the
expenses and fees for listing the securities to be registered on each securities
exchange on which similar securities issued by the Company are then listed or on
a securities exchange or the NASD automated quotation system.

          (b)  In connection with each Demand Registration and each Piggyback
Registration, the Company shall reimburse the holders of Registrable Securities
included in such registration for the reasonable fees and disbursements of one
counsel chosen by the holders of a majority of the Registrable Securities
included in such registration.

          (c)  To the extent Registration Expenses are not required to be paid
by the Company, each holder of securities included in any registration hereunder
will pay those Registration Expenses allocable to the registration of such
holder's securities so included, and any Registration Expenses not so allocable
will be borne by all sellers of securities included in such registration in
proportion to the aggregate selling price of the securities to be so registered.

          6.   Indemnification.
               --------------- 

          (a)  The Company agrees to indemnify and hold harmless, to the full
extent permitted by law, each holder of Registrable Securities, its officers,
directors, agents, and employees and each Person who controls such holder
(within the meaning of the Securities Act) against any losses, claims, damages,
liabilities, joint or several, together with reasonable costs and expenses
(including reasonable attorney's fees), to which such indemnified party may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions or

                                     - 7 -

 
proceedings, whether commenced or threatened, in respect thereof) arise out of
or are based upon (i) any untrue or alleged untrue statement of material fact
contained (A) in any registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or (B) in any
application or other document or communication (in this Section 6 collectively

called an "application") executed by or on behalf of the Company or based upon
           -----------                                                        
written information furnished by or on behalf of the Company filed in any
jurisdiction in order to qualify any securities covered by such registration
statement under the "blue sky" or securities laws thereof, or (ii) any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, and the Company will
reimburse such holder and each such director, officer and controlling Person for
any legal or any other expenses incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; 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 or
proceeding in respect thereof) or expense arises out of or is based upon an
untrue statement or alleged untrue statement, or omission or alleged omission,
made in such registration statement, any such prospectus or preliminary
prospectus or any amendment or supplement thereto, or in any application, in
reliance upon, and in conformity with, written information prepared and
furnished to the Company by such holder expressly for use therein or by such
holder's failure to deliver a copy of the registration statement or prospectus
or any amendments or supplements thereto after the Company has furnished such
holder with a sufficient number of copies of the same.  In connection with an
underwritten offering, the Company will indemnify such underwriters, their
officers and directors and each Person who controls such underwriters (within
the meaning of the Securities Act) to the same extent as provided above with
respect to the indemnification of the holders of Registrable Securities.

          (b)  In connection with any registration statement in which a holder
of Registrable Securities is participating, each such holder will furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the full extent permitted by law, will indemnify and hold
harmless the other holders of Registrable Securities and the Company, and their
respective directors, officers, agents and employees and each other Person who
controls the Company (within the meaning of the Securities Act) against any
losses, claims, damages, liabilities, joint or several, together with reasonable
costs and expenses (including reasonable attorney's fees), to which such
indemnified party may become subject under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions or
proceedings, whether commenced or threatened, in respect thereof) arise out of
or are based upon (i) any untrue or alleged untrue statement of material fact
contained in the registration statement, prospectus or preliminary prospectus or
any amendment thereof or supplement thereto or in any application or (ii) any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only to the extent
that such untrue statement or omission is made in such registration statement,
any such prospectus or preliminary prospectus or any amendment or supplement
thereto, or in any application, in reliance upon and in conformity with written
information prepared and furnished to the Company by such holder expressly for
use therein; provided, however, that the obligation to indemnify will be
individual to each holder and will be limited to the net amount of proceeds
received by such holder from the sale of Registrable Securities pursuant to such
registration statement.

                                     - 8 -

 
          (c)  Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (provided that the failure to give prompt notice
shall not impair any Person's right to indemnification hereunder to the extent
such failure has not prejudiced the indemnifying party) and (ii) unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist with respect to such claim,
permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party.  If such defense is assumed,
the indemnifying party will not be subject to any liability for any settlement
made by the indemnified party without its consent (but such consent will not be
unreasonably withheld).  An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

          (d)  The indemnifying party shall not, except with the approval of
each indemnified party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to each indemnified party of a release from all
liability in respect to such claim or litigation without any payment or
consideration provided by such indemnified party.

          (e)  If the indemnification provided for in this Section 6 is
                                                           ---------   
unavailable to or is insufficient to hold harmless an indemnified party under
the provisions above in respect to any losses, claims, damages or liabilities
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 (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the sellers of
Registrable Securities and any other sellers participating in the registration
statement on the other from the sale of Registrable Securities pursuant to the
registered offering of securities as to which indemnity is sought or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company on
the one hand and of the sellers of Registrable Securities and any other sellers
participating in the registration statement on the other in connection with the
registration statement on the other in connection with the statement or
omissions which resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations.  The relative benefits received
by the Company on the one hand and the sellers of Registrable Securities and any
other sellers participating in the registration statement on the other shall be
deemed to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) to the Company bear to the total net proceeds from
the offering (before deducting expenses) to the sellers of Registrable
Securities and any other sellers participating in the registration statement.
The relative fault of the Company on the one hand and of the sellers of
Registrable Securities and any other sellers participating in the registration
statement on the other shall be determined by reference to, among other things,
whether the untrue or alleged omission to state a material fact relates to
information supplied by the Company or by the sellers of Registrable Securities
or other sellers

                                     - 9 -

 
participating in the registration statement and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

          The Company and the sellers of Registrable Securities agree that it
would not be just and equitable if contribution pursuant to this Section 6 were
                                                                 ---------     
determined by pro rata allocation (even if the sellers of Registrable Securities
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 in the immediately preceding paragraph.  The amount paid or payable by an
indemnified party as a result of the losses, claims, damages and liabilities
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim.  Notwithstanding the provisions of this
Section 6, no seller of Registrable Securities shall be required to contribute
- - ---------                                                                     
any amount in excess of the net proceeds received by such Seller from the sale
of Registrable Securities covered by the registration statement filed pursuant
hereto.  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.

          (f)  The indemnification and contribution by any such party provided
for under this Agreement shall be in addition to any other rights to
indemnification or contribution which any indemnified party may have pursuant to
law or contract and will remain in full force and effect regardless of any
investigation made or omitted by or on behalf of the indemnified party or any
officer, director or controlling Person of such indemnified party and will
survive the transfer of securities.

limitation, pursuant to the terms of any over-allotment or "green shoe" option
requested by the managing underwriter(s), provided that no holder of Registrable
Securities will be required to sell more than the number of Registrable
Securities that such holder has requested the Company to include in any

event the Company shall give any such notice, the applicable time period
mentioned in Section 4(b) during which a Registration Statement is to remain
             ------------                                                   
effective shall be extended by the number of days during the period from and
including the date of the giving of such notice pursuant to this Section
                                                                 -------

by such registration statement shall have received the copies of the
supplemented or amended prospectus contemplated by Section 4(e).

other jurisdiction, and this Agreement shall be reformed, construed and enforced
in such jurisdiction as if such invalid, illegal or unenforceable provision had
never been contained herein.
