furnish  promptly  to the Company  all  information  required 
to  be  disclosed  in  order  to  make  the information 
previously  furnished to the Company by such Holder not

or (iii)  subject to the provisions of Section 4(b)(i) below, is
filed and declared effective but, during the period specified in
Section  2(a)(ii)  hereof,  shall thereafter cease to be
effective or fail to be usable for its intended  purpose without
being succeeded within 15  Business  Days by a  post-effective 
amendment  to such  Registration Statement  that  cures  such 
failure  and that is itself  immediately  declared effective
(each such event referred to in foregoing clauses (i) through
(iii), a

                                        3



 "Registration  Default"),  the Company hereby agrees to pay 
liquidated  damages ("Liquidated  Damages")  to (A) each holder

Debentures held by such Holder; and (B) each Holder of shares of
Common Stock issued upon  conversion of Debentures with respect
to any period in which a Registration Default shall have
occurred and be continuing,  in an amount  equal to $.07 per 
annum  per share of Common  Stock, subject to adjustment in the
event of stock splits, stock recombinations,  stock dividends
and the like.

         (b)  All  accrued  Liquidated  Damages  shall  be paid 
to  holders  of Debentures or Record Holders by the Company on

or share of Common  Stock,  the  accrual  of  Liquidated 
Damages  with  respect  to such Debenture or share of Common
Stock will cease.

         4. Registration Procedures.

         (a) In connection with the Shelf  Registration 
Statement,  the Company shall  comply with all the  provisions 
of Section  4(b) below and shall use its best  efforts to effect
 such  registration  to permit the sale of the  Transfer
Restricted  Securities  being sold in  accordance  with the 
intended  method or methods of distribution  thereof,  and, 
pursuant  thereto,  the Company will as expeditiously  as 
possible  prepare  and  file  with  the  Commission  a  Shelf
Registration  Statement  relating to the  registration on any 
appropriate  form under the Securities Act.

         (b) In  connection  with  the  Shelf  Registration 
Statement  and  any Prospectus  required by this  Agreement to
permit the sale or resale of Transfer Restricted Securities, the
Company shall:

         (i)  Use  its  best  efforts  to  keep  such  
Registration   Statement continuously  effective  during the
period required by this Agreement;  upon the occurrence of any
event that would cause any such Registration  Statement or the
Prospectus contained therein (A) to contain a material 
misstatement or omission or (B) not be effective and usable for
resale of Transfer Restricted  Securities during the period
required by this Agreement, the Company shall file promptly an
appropriate amendment to such Registration Statement, in the
case of clause (A), correcting any such misstatement or
omission,  and, in the case of either clause (A) or (B),  use
its  reasonable  best  efforts  to cause such  amendment  to be
declared effective and such Registration Statement and the
related Prospectus to become usable for their  intended 
purposes as soon as  practicable  thereafter. Notwithstanding 
the  foregoing,  if the  Board  of  Directors  of  the  Company
determines in good faith that it is in the best  interests of
the Company not to disclose the existence of or facts 
surrounding any proposed or pending material corporate 
transaction  involving  the Company,  the Company may allow the
Shelf Registration  Statement to fail to be  effective  and
usable as a result of such nondisclosure  for (1) a period not
to exceed 30 days in any three month  period or (2) two periods 
not to exceed an  aggregate  of 60 days in any twelve  month
period.

                                        4





         (ii)  Prepare  and  file  with  the  Commission   such 
amendments  and post-effective  amendments to the Registration 
Statement as may be necessary to keep the  Registration 
Statement  effective for the period set forth in Section
2(a)(ii)  hereof or such  shorter  period as will  terminate 
when all  Transfer Restricted  Securities  covered by such 
Registration  Statement have been sold; cause the Prospectus to
be supplemented by any required  Prospectus  supplement, and as
so  supplemented  to be filed  pursuant to Rule 424 under the 
Securities Act, and to comply fully with the  applicable 
provisions  of Rules 424 and 430A under the Securities  Act in a
timely manner;  and comply with the provisions of the Securities
Act with respect to the disposition of all securities  covered
by such Registration  Statement during the applicable period in
accordance with the intended  method or methods of  distribution
by the sellers thereof set forth in such Registration Statement
or supplement to the Prospectus.

         (iii) Advise the  underwriter(s),  if any, and selling
holders promptly (but in any event within two Business  Days)
and, if requested by such  Persons, to confirm such advice in
writing,  (A) when the  Prospectus  or any  Prospectus
supplement or post-effective  amendment has been filed, and,
with respect to any Registration  Statement or any
post-effective  amendment thereto,  when the same has become
effective, (B) of any request by the Commission for amendments
to the Registration  Statement or amendments or  supplements  to
the  Prospectus or for additional  information  relating
thereto, (C) of the issuance by the Commission of any stop order
suspending the  effectiveness  of the  Registration  Statement
under the Securities Act or of the suspension by any state
securities commission of the qualification of the Transfer
Restricted  Securities for offering or sale in  any 
jurisdiction,  or  the  initiation  of any  proceeding  for  any
of the preceding  purposes,  (D) of the  existence of any fact
or the  happening of any event  that makes any  statement  of a 
material  fact made in the  Registration Statement, the
Prospectus,  any amendment or supplement thereto, or any
document incorporated  by reference  therein  untrue,  or that
requires the making of any additions to or changes in the
Registration Statement or the Prospectus in order to make the
statements  therein,  in light of the circumstances under which
they were made, not  misleading.  If at any time the Commission 
shall issue any stop order suspending the effectiveness of the
Registration  Statement,  or any state securities  commission 
or  other  regulatory  authority  shall  issue  an order
suspending the  qualification  or exemption from  qualification 
of the Transfer Restricted Securities under state securities or
Blue Sky laws, the Company shall use its  reasonable  best 
efforts to obtain the  withdrawal  or lifting of such order at
the earliest possible time.

         (iv)  Furnish  to  each  of  the  selling   holders 
and  each  of  the underwriter(s),  if any,  before  filing 
with  the  Commission,  copies  of any Registration  Statement
or any Prospectus  included therein or any amendments or
supplements to any such Registration  Statement or Prospectus 
(including,  upon request in writing,  all documents 
incorporated  by reference after the initial filing of such
Registration  Statement),  which documents will be subject to
the review of such  holders  and  underwriter(s),  if any,  for
a period of at least three  Business  Days,  and the  Company 
will not  file  any such  Registration Statement or Prospectus
or any amendment or supplement to any such  Registration
Statement or Prospectus (including all such documents
incorporated by reference) to which a selling  holder of 
Transfer  Restricted  Securities  covered by such Registration
Statement or the underwriter(s),  if any, shall, upon advice of
its counsel, reasonably object within three Business Days after
the receipt thereof.

                                        5



 A selling  holder or  underwriter,  if any,  shall be deemed to
have  reasonably objected to such filing if such Registration
Statement, amendment, Prospectus or supplement,  as  applicable,
 as  proposed  to be  filed,  contains  a  material misstatement
or omission.

         (v)  Promptly  before  the  filing  of  any  document 
that  is  to  be incorporated  by reference  into a

Registration Statement,  and any attorney or accountant retained
by such selling Holders or any of the underwriter(s), all
financial and other records, pertinent corporate  documents  and
 properties  of the  Company  and cause the  Company's officers,
directors, managers and employees to supply all information
reasonably requested by any such Holder, underwriter,  attorney
or accountant in connection with such  Registration  Statement 
after the  filing  thereof  and  before  its effectiveness.

         (vii) If requested  by any selling  Holders or the 
underwriter(s),  if any, promptly incorporate in any
Registration Statement or Prospectus,  pursuant to a supplement
or  post-effective  amendment if necessary,  such information as
such selling Holders and underwriter(s),  if any, may reasonably
request to have included therein,  including,  without
limitation,  information  relating to the "Plan of Distribution"
of the Transfer Restricted  Securities,  information with
respect to the principal amount of Transfer Restricted 
Securities being sold to such underwriter(s),  the purchase
price being paid therefor and any other terms of the  offering 
of the  Transfer  Restricted  Securities  to be  sold  in such
offering;  and  make all  required  filings  of such  Prospectus
 supplement  or post-effective amendment as soon as practicable
after the Company is notified of the matters to be incorporated
in such Prospectus  supplement or  post-effective amendment.

         (viii) Furnish to each selling  Holder and each of the 
underwriter(s), if any,  without charge,  at least one copy of
the  Registration  Statement,  as first filed with the
Commission,  and of each amendment  thereto,  including all

         (ix) Deliver to each selling Holder and each of the

Prospectus and any amendment or supplement  thereto by each of
the selling Holders and each of the  underwriter(s),  if any, in
connection with the offering and the sale of the Transfer
Restricted Securities covered by the Prospectus or any amendment
or supplement thereto.

         (x)  Whether  or not an  underwriting  agreement  is 
entered  into and whether or not the  registration  is an
Underwritten  Registration,  the Company shall: (A) upon
request, furnish to each selling Holder and each underwriter, if

the  underwriter(s),  if any,  and their respective  counsel in
connection with the registration and qualification of the
Transfer  Restricted  Securities  under the  securities or Blue
Sky laws of such jurisdictions as the selling Holders or 
underwriter(s),  if any, may reasonably request and do any and
all other acts or things necessary or advisable to enable the 
disposition in such  jurisdictions  of the Transfer  Restricted 
Securities covered by the Shelf Registration Statement;
provided, however, that the Company shall not be required to
register or qualify as a foreign  corporation  where it is not

it to the service of process, in any jurisdiction where they are
not now so subject.

         (xii)  Cooperate with the selling  Holders and the 
underwriter(s),  if any,  to  facilitate  the  timely

underwriter(s), if any, to consummate the disposition of such
Transfer Restricted Securities.

         (xiv)  Subject  to  Section   4(b)(i)  above,  if  any 
fact  or  event contemplated by Section 4(b)(iii)(D) above shall
exist or have occurred, prepare a  supplement  or 
post-effective  amendment  to the  Registration  Statement or
related Prospectus or any document incorporated therein by
reference or file any other  required  document so that, as
thereafter  delivered to the purchasers of Transfer  Restricted 
Securities,  the  Prospectus  will not  contain  an untrue

                                        7



 statement  of a material  fact or omit to state any material 
fact  necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

         (xv)  Cooperate and assist in any filings  required to

holders,  as  soon as  practicable,  a  consolidated  earnings
statement  meeting the  requirements of Rule 158 (which need not
be audited) for the twelve-month period (A) commencing at the
end of any fiscal quarter in which Transfer  Restricted 
Securities  are  sold  to  underwriters  in a firm or best
efforts  Underwritten  Offering  or (B) if not sold to 
underwriters  in such an offering,  beginning with the first
month of the Company's  first fiscal quarter commencing after
the effective date of the Registration Statement.

         (xvii) If required,  cause the Indenture to be
qualified  under the TIA not later than the effective date of
the first  Registration  Statement required by this Agreement,
and, in connection therewith, cooperate, with the trustee and
the holders of  Debentures  to effect such  changes to the 
Indenture  as may be required for such  Indenture to be so
qualified in accordance  with the terms of the TIA;  and execute
and use its  reasonable  best efforts to cause the trustee
thereunder to execute all documents  that may be required to
effect such changes and all other forms and  documents  required
to be filed with the  Commission to enable such Indenture to be
so qualified in a timely manner.

         (xviii)  Cause  all  Transfer  Restricted  Securities 
covered  by  the Registration  Statement  to be  listed  on each
 securities  exchange  on  which securities of the same class
issued by the Company are then listed.

         (xix)  Provide  promptly  to each  Holder  upon 
written  request  each document filed with the Commission 
pursuant to the  requirements  of Section 13 and Section 15 of
the Exchange Act after the Effective Date of the  Registration
Statement.

Restricted Security that,  upon receipt of any notice from the
Company of the  existence of any fact of the kind described in
Section 4(b)(iii)(D) hereof, such Holder will forthwith
discontinue  disposition  of  Transfer  Restricted  Securities 
pursuant  to the applicable  Registration  Statement until such
Holder's receipt of the copies of the supplemented or amended
Prospectus  contemplated by Section 4(b)(xv) hereof, or until it
is advised in writing (the  "Advice") by the Company that the
use of the  Prospectus  may be resumed,  and has received 
copies of any  additional or supplemental filings that are
incorporated by reference in the Prospectus. If so directed  by
the  Company,  each  Holder  will  deliver to the  Company  (at
the Company's  expense) all copies,  other than  permanent  file
copies then in such Holder's  possession,  of  the  Prospectus 
covering  such  Transfer  Restricted Securities that was current
at the time of receipt of such notice.

Securities;   (v)  all  application  and  filing  fees  in
connection  with  listing of the Common  Stock  issued  upon 
conversion  of the Debentures  on a national  securities 
exchange or  automated  quotation  system pursuant to the 
requirements  hereof;  and (vi) all fees and  disbursements  of
independent  certified public accountants of the Company
(including the expenses of any  special  audit and  comfort 
letters  required  by or  incident  to such performance), but
specifically excluding (a) fees and expenses of counsel to the
underwriter(s),  if any (other than fees and  expenses  set
forth in clauses (i) and (ii) above),  (b)  underwriting 
discounts and  commissions and (c) transfer fees  and  taxes  if
any,  relating  to the sale  and  disposition  of  Transfer
Restricted  Securities by a selling Holder. The Company will, in
any event, bear its internal expenses (including,  without
limitation, all salaries and expenses of its  officers and 
employees  performing  legal or  accounting  duties),  the
expenses of any annual audit and the fees and expenses of any
Person,  including special experts, retained by the Company.

         (b) In  connection  with any  Registration  Statement 
required by this Agreement,  the Company will reimburse the
Initial Purchasers and the Holders of Transfer   Restricted  
Securities  being  registered   pursuant  to  the  Shelf
Registration Statement, as applicable, for the reasonable fees
and disbursements of not more than one counsel  chosen by the 
Holders of a majority in  principal amount of  Debentures  and
in number of  shares  of  Common  Stock  issued  upon conversion
 thereof  for whose  benefit  such  Registration  Statement  is
being prepared.

         6. Indemnification and Contribution.

         (a) The  Company  and the  Subsidiaries  (as  defined 
in the  Purchase Agreement),  jointly and severally,  agree to
indemnify and hold  harmless:  (i) each  Holder;  (ii) each
person,  if any,  who  controls  (within the meaning of Section
15 of the  Securities  Act or Section 20 of the Exchange Act)
any Holder (any of the  persons  referred  to in this  clause 
(ii) being  referred to as a "controlling person"); and (iii)
the respective officers,  directors,  partners, employees, 
representatives  and agents of any Holder or any controlling 
person (any  person  referred  to in clause  (i),  (ii),  or
(iii) may  hereinafter  be referred to as an "Indemnified
Holders"), against any losses, claims, damages or liabilities, 
joint or  several,  to which  such  Indemnified  Holder may
become subject under the Securities Act, the Exchange Act or
otherwise,  insofar as any 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 of any material fact contained in (A) in any
Registration Statement or Prospectus or in any amendment or
supplement  thereto or (B) any  application or

                                        9



 other document, or any amendment or supplement thereto, 
executed by the Company or any Subsidiary or based upon written
information furnished by or on behalf of the Company or any
Subsidiary  filed in any jurisdiction in order to qualify the
Common Stock issued upon  conversion of the  Debentures  under
the securities or "Blue  Sky"  laws  thereof  or  filed  with 
the  Commission  or any  securities association or securities
exchange (each an "Application"); or (ii) the omission or
alleged  omission to state, in such  Registration  Statement or
Prospectus or any  amendment or supplement  thereto,  or in any 
Application,  a material fact required to be stated  therein or
necessary to make the statements  therein,  in the light of the
circumstances  under which they were made, not misleading,  and
will  reimburse,  as incurred,  each  Indemnified  Holder for
any legal or other expenses reasonably incurred by such
Indemnified Holder or controlling person 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,  neither  the Company 
nor any of the  Subsidiaries  will be liable in any such case to
the extent  that any such  loss,  claim,  damage,  or liability
is finally judicially  determined to arise out of or be based
upon any untrue  statement or alleged  untrue  statement or
omission or alleged  omission made in such  Registration 
Statement or  Prospectus  or amendment or supplement thereto  or
 Application  in  reliance  upon  and  in  conformity  with 
written information  furnished to the Company through the
Holders by or on behalf of any Holder (or its related 
Indemnified Holder)  specifically for use therein.  This
indemnity  agreement  will be in addition to any liability  that
the Company and the Subsidiaries may otherwise have to the
Indemnified  Holders. The Company and the Subsidiaries  shall
not be liable under this Section 6 for any settlement of any 
claim  or  action  effected  without  their  consent,  which 
shall  not be unreasonably withheld.

         (b) Each Holder,  severally  and not jointly,  will 
indemnify and hold harmless  each of the Company and each
person,  if any, who controls the Company within the  meaning of
 Section  15 of the  Securities  Act or Section 20 of the
Exchange Act against any losses,  claims,  damages or 
liabilities  to which the Company or any such  controlling 
person may become subject under the Securities Act, the Exchange
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 of any material fact contained in the  Registration 
Statement or the Prospectus or any amendment or supplement
thereto or any Application or (ii) the omission or the alleged
omission to state therein a material fact required to be stated
therein,  or necessary to make the statements  therein not
misleading,  in 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 through the Holders by or on behalf of any Holder or its
related  Indemnified  Holder  specifically  for use therein; 
and, subject to the limitation  set forth  immediately 
preceding  this clause,  will reimburse,  as incurred,  any
legal or other expenses incurred by the Company or any
controlling  person in connection with investigating or
defending against or appearing  as a third party  witness in 
connection  with any such loss,  claim, damage, liability or
action in respect thereof. This indemnity agreement will be in 
addition  to any  liability  that  any  Holder  may  otherwise 
have  to the indemnified  parties.  No Holder  shall be liable 
under this  Section 6 for any settlement of any claim or action
effected without its consent,  which shall not

                                       10



 be unreasonably  withheld. In no event shall the liability of
any selling Holder hereunder be greater in amount than the
dollar  amount of the proceeds  received by such Holder upon the
sale of Transfer  Restricted  Securities  giving rise to such
indemnification obligation.

         (c) Promptly after receipt by an indemnified party
under this Section 6 of notice of the commencement of any action
for which such indemnified  party is entitled to 
indemnification  under this Section 6, such indemnified party
will, if a claim in respect thereof is to be made against the
indemnifying party under this Section 6, notify the indemnifying
party of the commencement  thereof;  but the  omission so to
notify the  indemnifying  party (i) will not relieve it from any
liability  under  paragraph (a) or (b) above unless and to the
extent it did not otherwise learn of such action and such
failure results in the forfeiture by the indemnifying  party of
substantial rights and defenses and (ii) will not, in any 
event,   relieve  the  indemnifying  party  from  any 
obligations  to  any indemnified  party  other  than  the 
indemnification   obligation  provided  in paragraphs  (a) and
(b) above.  In case any such  action is brought  against any
indemnified  party, and it notifies the  indemnifying  party of
the commencement thereof,  the indemnifying party will be
entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party; provided, however, that
if (i) the use of counsel chosen by the indemnifying  party to
represent the indemnified party would present such counsel  with
a conflict of  interest,  (ii) the  defendants  in any such
action include  both  the  indemnified  party  and  the 
indemnifying   party  and  the indemnified  party shall have
been  advised by counsel  that there may be one or more legal 
defenses  available  to it and other  indemnified  parties  that
are different  from or additional to those  available to the 
indemnifying  party or (iii)  the  indemnifying  party  shall 
not  have  employed  counsel  reasonably satisfactory to the
indemnified  party to represent the indemnified party within a
reasonable time after notice of the institution of such action, 
then, in each such case, the indemnifying party shall not have
the right to direct the defense of such  action  on  behalf  of
such  indemnified  party  or  parties  and  such indemnified 
party or parties shall have the right to select separate counsel
to defend such action on behalf of such indemnified party or
parties.  After 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 6
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 immediately  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, designated
 by the Holders in the case of paragraph (a) of this Section 6
or the Company  in the  case of  paragraph  (b) of this  Section
 6,  representing  the indemnified  parties under such 
paragraph (a) or paragraph (b), as the case may be, who are
parties to such action or  actions) or (ii) the  indemnifying 
party has authorized in writing the employment of counsel for
the indemnified party at the expense of the indemnifying  party.
 After such notice from the indemnifying party to such
indemnified  party, the indemnifying  party will not be liable
for the costs  and  expenses  of any  settlement  of such 
action  effected  by such indemnified party without the consent
of the indemnifying party, unless such

                                       11





indemnified  party  waived in writing its rights  under this
Section 6, in which case the indemnified party may effect such a
settlement without such consent.

         (d) In circumstances in which the indemnity  agreement 
provided for in the preceding  paragraphs of this Section 6 is 
unavailable or  insufficient  to hold harmless an indemnified
party in respect of any losses,  claims, damages or liabilities
(or actions in respect thereof),  each indemnifying  party, in
order to provide for just and equitable  contribution,  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 (i) the relative benefits received
by the Company and the Subsidiaries on the one hand and any
Holder on the other from such Holder's sale of Transfer 
Restricted  Securities  or (ii) if the  allocation  provided by
the foregoing  clause (i) is not permitted by applicable law,
not only such relative benefits but also the relative fault of
the Company and the  Subsidiaries on the one hand and such 
Holder  on the other in  connection  with the  statements  or
omissions  or alleged  statements  or  omissions  that  resulted
in such losses, claims,  damages or liabilities  (or actions in
respect  thereof).  The relative fault of the parties  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 
Subsidiaries  on the one hand or such Holder on the other, the
parties'  relative intent,  knowledge,  access to information
and opportunity  to correct or prevent such  statement  or 
omission,  and any other equitable  considerations  appropriate
in the  circumstances.  The Company,  the Subsidiaries  and each
Holder of Transfer  Restricted  Securities  agree that it would
not be equitable if the amount of such contribution were
determined by pro rata or per capita allocation or by any other
method of allocation that does not take into account the
equitable considerations referred to in the first sentence of
this paragraph (d). Notwithstanding the provisions of this
Section 6(d), none of the Holders (or any of their related 
Indemnified  Holders) shall be required to  contribute  any
amount in excess of the  amount by which the total  discount
received by such Holder with respect to the Common Stock issued
upon  conversion thereof  exceeds the amount of any damages
which such Holder has otherwise  paid or become liable to pay by
reason of any 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
Securities Act) shall be entitled to contribution   from  any 
person   who  was  not   guilty  of  such   fraudulent
misrepresentation.  For purposes of this paragraph (d), each
person, if any, who controls any Holder  within the meaning of
Section 15 of the  Securities  Act or Section 20 of the 
Exchange  Act shall have the same rights to  contribution  as
such Holder, and each person, if any, who controls the Company
or any Subsidiary within the  meaning of  Section  15 of the 
Securities  Act or Section 20 of the Exchange Act, shall have
the same rights to contribution as the Company.

         7. Rule 144A. The Company  hereby agrees with each
Holder,  for so long as any Transfer Restricted  Securities
remain outstanding,  to make available to any Holder or
beneficial owner of Transfer  Restricted  Securities in
connection with any sale thereof and any prospective  purchaser
of such Transfer Restricted Securities from such Holder or
beneficial  owner,  the  information  required by Rule 
144A(d)(4)  under the  Securities  Act in order to permit 
resales of such Transfer Restricted Securities pursuant to Rule
144A.

                                       12





         8.   Participation  in  Underwritten   Registrations.  
No  Holder  may participate in any  Underwritten  Registration 
hereunder unless such Holder (a) agrees  to sell  such  Holder's
 Transfer  Restricted  Securities  on the  basis provided in any
 underwriting  arrangements  approved  by the  Persons  entitled
hereunder  to approve  such  arrangements  and (b)  completes 
and  executes all reasonable  questionnaires,   powers  of 
attorney,  indemnities,   underwriting agreements,  lockup
letters and other documents required under the terms of such
underwriting arrangements.

         9.  Selection  of  Underwriters.  The  Holders of 
Transfer  Restricted Securities covered by the Shelf 
Registration  Statement who desire to do so may sell such
Transfer  Restricted  Securities in an Underwritten  Offering. 
In any such  Underwritten  Offering,  the investment  banker or
investment  bankers and manager or managers  that will 
administer  the offering will be selected by the Holders  of a 
majority  in number of shares of Common  Stock  included  in
such offering; provided, that such investment bankers and
managers must be reasonably satisfactory to the Company.

         10. Miscellaneous.

         (a) Remedies.  The Company agrees that monetary damages
 (including the Liquidated Damages contemplated  hereby) would
not be adequate  compensation for any  loss  incurred  by 
reason  of a  breach  by it of the  provisions  of this
Agreement other than with respect to  Registration  Defaults and
hereby agree to waive the defense in any action for  specific 
performance  that a remedy at law would be adequate.

         (b) No Inconsistent  Agreements.  The Company will not,
on or after the date of this Agreement,  enter into any
agreement with respect to its securities that is inconsistent
with the rights granted to the Holders in this Agreement or
otherwise  conflicts with the provisions  hereof. The Company
has not previously entered  into any  agreement  granting any 
registration  rights with respect to their securities to any
Person which rights conflict with the provisions hereof. The
rights granted to the Holders  hereunder do not in any way
conflict with and are not  inconsistent  with the rights 
granted to the holders of the  Company's securities under any
agreement in effect on the date hereof.

         (c) Amendments and Waivers. This Agreement may not be
amended, modified or  supplemented,  and waivers or consents to
or departures  from the provisions hereof may not be given, 
unless the Company has obtained the written consent of Holders 
of a  majority  in number of shares of Common  Stock as 
issuable  upon conversion of the Debentures, as the case may be.

         (d)  Notices.  All notices  and other  communications 
provided  for or permitted hereunder shall be made in writing by
hand-delivery,  first-class mail (registered or certified, 
return receipt requested),  telex, telecopier, or air courier

inure to the benefit of and be  binding  upon the  successors 
and  assigns  of each of the  parties, including  without 
limitation  and without the need for an express  assignment,
subsequent Holders of Transfer Restricted  Securities; 
provided,  however, that this Agreement  shall not inure to the
benefit of or be binding upon a successor or assign of a Holder
unless and to the extent such successor or assign acquired
Transfer Restricted Securities from such Holder.

         (b)  Counterparts.  This  Agreement  may be  executed 
in any number of counterparts and by the parties hereto in
separate  counterparts,  each of which when so  executed  shall
be  deemed  to be an  original  and all of which  taken together
shall constitute one and the same agreement.

         (c) Headings.  The headings in this  Agreement are for 
convenience  of reference only and shall not limit or otherwise
affect the meaning hereof.

         (d) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE  WITH  THE LAWS OF THE  STATE  OF
NEW  YORK,  WITHOUT  REGARD  TO THE CONFLICT OF LAW RULES
THEREOF.

         (e)  Severability.  If any  one or  more  of the 
provisions  contained herein, or the application thereof in any
circumstance, is held invalid, illegal or  unenforceable,  the 
validity,  legality  and  enforceability  of  any  such
provision  in every other  respect  and of the  remaining

thereby.

         (f) Entire  Agreement.  This  Agreement is intended by
the parties as a final  expression of their agreement and
intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto in respect of
the  subject  matter  contained  herein.  There are no 
restrictions,  promises, warranties  or  undertakings,  other

                                       14



 the  Transfer  Restricted  Securities.   This  Agreement 
supersedes  all  prior agreements and  understandings  between
the parties with respect to such subject matter.
