            The Investors (on behalf of themselves and all permitted 
assignees who are Holders of Registrable Securities) may request at any time 
that the Company file a Registration Statement under the Securities Act on an 
appropriate form (which form shall be available for the sale of the 
Registrable Securities in accordance with the intended method or methods of 
distribution thereof and shall include all financial statements required by 
the SEC to be filed herewith) covering the shares of Registrable Securities 
that are the subject of such request.

       (b)  NUMBER OF DEMAND REGISTRATIONS; REQUIRED THRESHOLD.

            The Company shall be obligated to prepare, file and cause to 
become effective pursuant to this Section 2 no more than two (2) Registration 
Statements in the aggregate for the Investors (on behalf of themselves and 
all permitted assignees who are Holders of Registrable Securities); provided, 
however, that a Registration Statement shall not be counted as one of the two 
(2) Demand Registrations hereunder unless it becomes effective and is 
maintained effective in accordance with the requirements specified in Section 
5(a).  The Company shall not be obligated to prepare, file and cause to 
become effective pursuant to this Section 2 a Registration Statement unless 
the proposed aggregate public offering price of the Registrable Securities to 
be included in such Demand Registration is at least $5 million.

       (c)  DEFERRAL BY COMPANY.

            Notwithstanding anything in this Section 2 to the contrary, the 
Company shall not be obligated to prepare, file and cause to become effective 
pursuant to this Section 2 a Registration Statement if the Company furnishes 
the Investors a certificate signed by the President of the Company that in 
the good faith judgment of the Board of Directors it would be detrimental in 
any material respect to the Company and its shareholders for the Company to 
comply with the Demand Registration, and it is therefore essential to defer 
the filing of the Registration Statement relating thereto.  Any such deferral 
shall be for a period of not more than six (6) months after the Company's 
receipt of the Investor's written request for registration pursuant to this 
Section 2; PROVIDED, HOWEVER, that the Company may not exercise this right 
more than once with respect to a Demand Registration and that any requested 
registration deferred, and not ultimately effected, by the Company pursuant 
to the provisions of this Section 2(c) shall thereafter not be deemed to be a 
requested registration for purposes of the limitation to two (2) Demand 
Registrations pursuant to Section 2(a) above.

                                       5


       (d)  PARTICIPATION.

            The Company shall promptly give written notice to all Holders of 
Registrable Securities and to GE upon receipt of a request for a Demand 
Registration pursuant to Section 2(a) above.  GE may, by written notice to 
the Company and the Investors, within thirty (30) business days of the 
Company's notice, elect to join in a request for a Demand Registration 
pursuant to Section 2(a) above, with respect to a number of shares of GE 
Registrable Securities that is less than or equal to the number of shares of 
Registrable Securities requested to be registered in such Demand Registration 
by the Investors.  The GE Registrable Securities being offered by GE in such 
Demand Registration shall be treated pari passu with the Registrable 
Securities being offered by the Investors for all purposes including 
"underwriter's cutbacks" under subsection (e) of this Section and any such 
request by GE shall not be treated as either a request for "piggyback" rights 
under Section 3 hereof or be treated as the exercise of a demand registration 
right by GE under the GE Registration Rights Agreement.  In addition, the 
Company shall include in such Demand Registration such shares of Registrable 
Securities for which it has received written requests to register such shares 
within thirty (30) days after such written notice has been given.

       (e)  UNDERWRITER'S CUTBACK.

            If the public offering of Registrable Securities and/or GE 
Registrable Securities is to be underwritten and, in the good faith judgment 
of the managing underwriter, the inclusion of all the Registrable Securities 
and/or GE Registrable Securities requested to be registered hereunder would 
interfere with the successful marketing of a smaller number of such shares of 
Registrable Securities and/or GE Registrable Securities, the number of shares 
of Registrable Securities and/or GE Registrable Securities to be included 
shall be reduced to such smaller number with the participation in such 
offering to be pro rata among the Holders of Registrable Securities and/or GE 
Registrable Securities requesting such registration, based upon the number of 
shares of Registrable Securities and/or GE Registrable Securities owned by 
such Holders.

            Any shares that are thereby excluded from the offering shall be 
withheld from the market by the Holders thereof for a period (not to exceed 
thirty (30) days prior to the effective date and one hundred twenty (120) 
days thereafter) that the managing underwriter reasonably determines is 
reasonably necessary in order to successfully market the securities  to be 
offered in the Underwritten Offering.

            The Company and, subject to the requirements of Section 11 
hereof, other Holders of securities of the Company may include such 
securities in such Registration if, but only if, the managing underwriter 
concludes that such inclusion will not interfere with the successful 
marketing of all the Registrable Securities requested to be included in such 
registration.

       (f)  MANAGING UNDERWRITER.

            The managing underwriter or underwriters of any Underwritten 
Offering covered by a Demand Registration shall be selected by Investors 
participating in the Underwritten Offering owning a majority of the shares of 
Common Stock to be offered therein, subject to the 

                                       6


approval of the Board of Directors (by a majority of the Directors not 
elected by the holders of the Preferred Stock and the Series C Preferred 
Stock), which approval shall not be unreasonably withheld.

3.   PIGGYBACK REGISTRATIONS

       (a)  PARTICIPATION.

            Each time the Company decides to file a Registration Statement 
under the Securities Act (other than registrations on Forms S-4 or S-8 or any 
successor form thereto, and other than a Demand Registration) covering the 
offer and sale by it or any of its security holders of any of its securities 
for money, the Company shall give written notice thereof to all Holders of 
Registrable Securities.  The Company shall include in such Registration 
Statement such shares of Registrable Securities for which it has received 
written requests to register such shares within twenty (20) days after such 
written notice has been given.  If the Registration Statement is to cover an 
Underwritten Offering, such Registrable Securities shall be included in the 
underwriting on the same terms and conditions as the securities otherwise 
being sold through the underwriters.

       (b)  UNDERWRITER'S CUTBACK.

            Subject to the requirements of Section 11 hereof, if in the good 
faith judgment of the managing underwriter of such offering the inclusion of 
all of the shares of Registrable Securities and any other Common Stock 
requested to be registered would interfere with the successful marketing of a 
smaller number of such shares, then the number of shares of Registrable 
Securities and other Common Stock to be included in the offering shall be 
reduced to such smaller number with the participation in such offering to be 
in the following order of priority:  (1) first, the shares of Common Stock 
which the Company proposes to sell for its own account, (2) second, the 
shares of Registrable Securities of all Holders of Registrable Securities 
requested to be included, PARI PASSU with all shares of GE Registrable 
Securities requested by GE to be included and all shares of any Person 
granted "piggyback" registration rights by the Company prior to the date 
hereof with respect to the Company's securities, as set forth in Schedule A 
attached hereto, requested by such Person to be included, and (3) third, any 
other shares of Common Stock requested to be included.  Any necessary 
allocation among the Holders of shares within each of the foregoing groups 
shall be pro rata among such Holders requesting such registration based upon 
the number of shares of Common Stock and Registrable Securities owned by such 
Holders.

            All shares so excluded from the Underwritten Offering shall be 
withheld from the market by the Holders thereof for a period (not to exceed 
thirty (30) days prior to the effective date and one hundred twenty (120) 
days thereafter) that the managing underwriter reasonably determines is 
reasonably necessary in order to successfully market the securities  to be 
offered in the Underwritten Offering.

                                       7



       (c)  COMPANY CONTROL.

            The Company may decline to file a Registration Statement after 
giving notice to Holders pursuant to Section 3(a) above, or withdraw a 
Registration Statement after filing and after such notice, but prior to the 
effectiveness thereof; provided that the Company shall promptly notify each 
Holder of Registrable Securities in writing of any such action and provided 
further that the Company shall bear all expenses incurred by each Holder or 
otherwise in connection with such withdrawn Registration Statement.

4.   HOLD-BACK AGREEMENTS

       (a)  BY HOLDERS OF REGISTRABLE SECURITIES

            Upon the written request of the managing underwriter of any 
Underwritten Offering of the Company's securities, a Holder of Registrable 
Securities shall not sell, make any short sale of, loan, grant any option for 
the purchase of, or otherwise dispose of any Registrable Securities (other 
than those included in such registration) without the prior written consent 
of such managing underwriter for a period (not to exceed thirty (30) days 
before the effective date and one hundred twenty (120) days thereafter) that 
such managing underwriter reasonably determines is necessary in order to 
effect the Underwritten Offering; provided that each of the officers and 
directors of the Company shall have entered into substantially similar 
holdback agreements with such managing underwriter covering at least the same 
period.

       (b)  BY THE COMPANY AND OTHERS.

            The Company agrees:

               (1)  not to effect any public or private sale or distribution of
     its Equity Securities during the 30-day period prior to, and during the 
     60-day period after, the effective date of each Underwritten Offering made
     pursuant to a Demand Registration or a Piggyback Registration, if so
     requested in writing by the managing underwriter (except as part of such
     Underwritten Offering, pursuant to registrations on Forms S-4 or S-8 or any
     successor forms thereto or private issuances of Equity Securities as
     consideration for any acquisition by the Company or a subsidiary of assets
     or capital stock of any unaffiliated third party), and

               (2)  not to issue any Equity Securities other than for sale in a
     registered public offering unless each of the Persons to which such
     securities are issued has entered a written agreement binding on its
     transferees not to effect any public sale or distribution of such
     securities (except for employee stock options issued to Persons other than:
     directors or officers; or shareholders owning five percent (5%) or more of
     the Company's Equity Securities) during such period, including without
     limitation a sale pursuant to Rule 144 under the Securities Act (except as
     part of such Underwritten Registration, if and to the extent permitted
     hereunder).

                                       8


5.   REGISTRATION PROCEDURES

            If and whenever the Company is required to register Registrable 
Securities in a Demand Registration,, the Company will use all commercially 
reasonable efforts to effect such registration to permit the sale of such 
Registrable Securities in accordance with the intended plan of distribution 
thereof.  With respect to both Demand Registrations and Piggyback 
Registrations (except as otherwise specifically provided), the Company will 
as expeditiously as practicable:

            (a)  prepare and file with the SEC as soon as practicable a 
Registration Statement with respect to such Registrable Securities and use

Statement was declared effective, and (ii) the date the last of the 
Registrable Securities covered by such Registration Statement have been sold, 
provided that before filing a Registration Statement or Prospectus or any 
amendments or supplements thereto, the Company shall furnish to Holders of 
Registrable Securities covered by such Registration Statement and the 
underwriters, if any, draft copies of all such documents proposed to be 
filed, which documents will be subject to the review of such Investor and

Investor or the underwriters, if any, shall reasonably object;

            (b)  prepare and file with the SEC such amendments and 
post-effective amendments to the Registration Statement, and such supplements 
to the Prospectus, as may be requested by any underwriter of Registrable 
Securities or as may be required by the rules, regulations or instructions 
applicable to the registration form used by the Company or by the Securities 
Act or rules and regulations thereunder to keep the Registration Statement 
effective until all Registrable Securities covered by such Registration 
Statement are sold in accordance with the intended plan of distribution set 
forth in such Registration Statement or supplement to the Prospectus;

            (c)  promptly notify the selling Holders of Registrable 
Securities and the managing underwriter, if any, and (if requested by any 
such Person) confirm such advice in writing,

                 (1)  when the Prospectus or any supplement or post-effective
     amendment has been filed, and, with respect to the Registration Statement
     or any post-effective amendment, when the same has become effective,

     the Registration Statement or the Prospectus or for additional information,

     the effectiveness of the Registration Statement or the initiation of any
     proceedings for that purpose,

               (4)  if at any time the representations and warranties of the 
     Company contemplated by clause (1) of paragraph (o) below cease to be 
     accurate  in all material respects,

               (5)  of the receipt by the Company of any notification with 
     respect to the suspension of the qualification of the Registrable 
     Securities for sale in any jurisdiction or the initiation or threatening 
     of any proceeding for such purpose, and

               (6)  of the existence of any fact which results in the 
     Registration Statement, the Prospectus or any document incorporated 
     therein by reference containing a Misstatement;

          (d)  make all commercially reasonable efforts to obtain the 
withdrawal of any order suspending the effectiveness of the Registration 
Statement at the earliest practicable time;

          (e)  unless the Company objects in writing on reasonable grounds,

promptly as practicable incorporate in a supplement or post-effective 
amendment such information as the managing underwriter and the Investors

Securities, including, without limitation, information with respect to the

and make the Company's representatives available for discussion of such 
document and make such changes in such document prior to the filing thereof 
as counsel for the Investors or underwriters may reasonably request;

          (g)  furnish to each selling Holder of Registrable Securities and

reasonably request (the Company hereby consenting to the use of each such 
Prospectus (or preliminary prospectus) by each of the selling Holders of 
Registrable Securities 


                                      10



and the underwriters, if any, in connection with the offering and sale of the 
Registrable Securities covered by such Prospectus (or preliminary 
prospectus));

          (i)  prior to any public offering of Registrable Securities, use 
all commercially reasonable efforts to register or qualify or cooperate with 
the selling Holders of Registrable Securities, the underwriters, if any, and 
their respective counsel in connection with the registration or qualification

blue sky laws of such jurisdictions as such Investor or underwriters may 
designate in writing and do anything else necessary or advisable to enable 
from a legal perspective the disposition in such jurisdictions of the 
Registrable Securities covered by the Registration Statement; provided that 
the Company shall not be required to qualify generally to do business in any 
jurisdiction where it is not then so qualified or to take any action which 
would subject it to general service of process in any such jurisdiction where 
it is not then so subject;

          (j)  cooperate with the selling Holders of Registrable Securities 
and the managing underwriter, if any, to facilitate the timely preparation 
and delivery of certificates not bearing any restrictive legends representing 
the Registrable Securities to be sold and cause such Registrable Securities 
to be in such denominations and registered in such names as the managing 
underwriter may request at least three business days prior to any sale of 
Registrable Securities to the underwriters;

          (k)  use all commercially reasonable efforts to cause the

necessary to enable the seller or sellers thereof or the underwriters, if 
any, to consummate the disposition of such Registrable Securities;

          (l)  if the Registration Statement or the Prospectus contains a 
Misstatement, prepare a supplement or post-effective amendment to the

therein by reference or file any other required document so that, as 
thereafter delivered to the purchasers of the Registrable Securities, the 
Prospectus will not contain a Misstatement;

          (m)  use all commercially reasonable efforts to cause all 
Registrable Securities covered by the Registration Statement to be listed on 
any national securities exchange on which the Company's securities are listed 
or authorized for quotation on Nasdaq, if requested by the Investors (on 
behalf of themselves and all permitted assignees who are Holders of 
Registrable Securities) or the managing underwriter, if any; provided, 
however, that the payment of any required listing or other fee shall always 
be deemed to be "commercially reasonable" for purposes of this Section 5(m);

          (n)  provide a CUSIP number for all Registrable Securities not 
later than the effective date of the Registration Statement;

          (o)  enter into such agreements (including an underwriting 
agreement) and do anything else reasonably necessary or advisable in order to 
expedite or facilitate the disposition 


                                      11



of such Registrable Securities, and in such connection, whether or not the 
registration is an Underwritten Registration:

          (1)  make such representations and warranties to the Holders of

     substance and scope as are customarily made by issuers to holders and 
     underwriters, respectively, in similar Underwritten Offerings;

          (2)  obtain opinions of counsel to the Company and updates thereof

     selling Holders of Registrable Securities and the underwriters, if any, 
     such letters to be in customary form and covering matters of the type 
     customarily covered in "cold comfort" letters by holders and 
     underwriters, respectively, in connection with similar Underwritten 
     Offerings;

          (4)  if an underwriting agreement is entered into, cause the same to 
     include customary indemnification and contribution provisions and 
     procedures with respect to such underwriters; and

          (5)  deliver such documents and certificates as may be reasonably 
     requested by the Investor (on behalf of itself and all permitted 
     assignees who are Holders of Registrable Securities) and the managing 
     underwriter, if any, to evidence compliance with clause (1) above and 
     with any customary conditions contained in the underwriting agreement or 
     other agreement entered into by the Company.

The above shall be done at each closing under such underwriting or similar

Registrable Securities);

          (p)  make available for inspection by representatives of TC Group,

court or administrative order; and

any fiscal quarter in which Registrable Securities are sold to underwriters 
in an Underwritten Offering, or, 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, 
which statements shall cover said 12-month period.

6.   REGISTRATION EXPENSES

     (a)  DEMAND REGISTRATIONS.

          The Company shall bear all Registration Expenses incurred in 
connection with any Demand Registrations and of any Registrations which do 
not become or are not maintained effective in accordance with the 
requirements specified in Section 5(a) other than any Registration terminated 
prior to effectiveness at the request of, or primarily as a result of, the 
actions of Holders whose Registrable Securities are included in such 
registration. Notwithstanding the foregoing, the Underwriters' Commissions 
incurred in connection with a Demand Registration that becomes effective 
shall be shared by the Holders of the Registrable Securities whose 
Registrable Securities are included in such Registration and the Holders of 
the GE Registrable Securities whose GE Registrable Securities are included in 
such Registration, pro rata, in accordance with the aggregate amount of 
Registrable Securities and GE Registrable Securities sold by such Holders.

     (b)  PIGGYBACK REGISTRATIONS.

          The Company shall bear all Registration Expenses incurred in 
connection with any Piggyback Registrations, except that each Holder of the 
Registrable Securities whose Registrable Securities are included in such 
Registration shall pay its pro rata share of the Underwriters' Commissions 
incurred in such Registration, in accordance with the amount of Registrable 
Securities sold by all such Holders.

     (c)  COMPANY EXPENSES.

          The Company also will, in any event, pay its internal expenses 
(including, without limitation, all salaries and expenses of its officers and

securities to be registered on a securities exchange, and the fees and

                                      13



7.   INDEMNIFICATION

     (a)  INDEMNIFICATION BY COMPANY.

          The Company agrees to indemnify and hold harmless each Indemnified 
Holder from and against all Claims arising out of or based upon any 
Misstatement or alleged Misstatement, except insofar as such Misstatement or 
alleged Misstatement was based upon information furnished in writing to the 
Company by such Indemnified Holder expressly for use in the document 
containing such Misstatement or alleged Misstatement.  This indemnity shall 
not be exclusive and shall be in addition to any liability which the Company 
may otherwise have.

          The foregoing notwithstanding, the Company shall not be liable to 
the extent that any such Claim arises out of or is based upon a Misstatement 
or alleged Misstatement made in any preliminary prospectus if (i) such 
Indemnified Holder failed to send or deliver a copy of the Prospectus with or 
prior to the delivery of written confirmation of the sale of Registrable 
Securities giving rise to such Claim and (ii) the Prospectus would have 
corrected such untrue statement or omission.

          In addition, the Company shall not be liable to the extent that any 
such Claim arises out of or is based upon a Misstatement or alleged 
Misstatement in a Prospectus, (x) if such Misstatement or alleged 
Misstatement is corrected in an amendment or supplement to such Prospectus 
and (y) having previously been furnished by or on behalf of the Company with 
copies of the Prospectus as so amended or supplemented, such Indemnified 
Holder thereafter fails to deliver such Prospectus as so amended or 
supplemented prior to or concurrently with the sale to the person who 
purchased a Registrable Security from such Indemnified Holder and who is 
asserting such Claim.

          The Company shall also provide customary indemnifications to 
underwriters, selling brokers, dealer managers and similar securities 
industry professionals participating in a distribution covered by a 
Registration Statement, their officers and directors and each Person who 
controls such Persons (within the meaning of Section 15 of the Securities Act 
or Section 20 of the Exchange Act).

     (b)  INDEMNIFICATION PROCEDURES.

          If any action or proceeding (including any governmental 
investigation or inquiry) shall be brought or asserted against an Indemnified 
Holder in respect of which indemnity may be sought from the Company, such 
Indemnified Holder shall promptly notify the Company in writing, and the 
Company may assume the defense thereof, including the employment of counsel 
reasonably satisfactory to such Indemnified Holder and the payment of all 
expenses.

          Such Indemnified Holder shall have the right to employ separate 
counsel in any such action and to participate in the defense thereof, but the 
fees and expenses of such separate counsel shall be at the expense of such 
Indemnified Holder unless (i) the Company has agreed to pay such fees and 
expenses, (ii) the Company shall have failed to assume the defense of such 
action or proceeding or has failed to employ counsel reasonably satisfactory 
to such Indemnified 


                                      14



Holder in any such action or proceeding, or (iii) the named parties to any 
such action or proceeding (including any impleaded parties) include both such 
Indemnified Holder and the Company, and such Indemnified Holder shall have 
been advised in writing by counsel that there may be one or more legal 
defenses available to such Indemnified Holder that are different from or 
additional to those available to the Company.

          If such Indemnified Holder notifies the Company in writing that it 
elects to employ separate counsel at the expense of the Company as permitted 
by the provisions of the preceding paragraph, the Company shall not have the 
right to assume the defense of such action or proceeding on behalf of such 
Indemnified Holder.  The foregoing notwithstanding, the Company shall not be 
liable for the reasonable fee and expenses of more than one separate firm of 
attorneys at any time for such Indemnified Holder and any other Indemnified 
Holders (which firm shall be designated in writing by such Indemnified 
Holders) in connection with any one such action or proceeding or separate but 
substantially similar or related actions or proceedings in the same 
jurisdiction arising out of the same general allegations or circumstances.

          The Company shall not be liable for any settlement of any such 
action or proceeding effected without its written consent, but if settled 
with its written consent, or if there be a final judgment for the plaintiff 
in any such action or proceeding, the Company agrees to indemnify and hold 
harmless such Indemnified Holders from and against any loss or liability by 
reason of such settlement or judgment.

     (c)  INDEMNIFICATION BY HOLDER OF REGISTRABLE SECURITIES.

          Each Holder of Registrable Securities agrees to indemnity and hold 
harmless the Company, its directors and officers and each Person, if any, who 
controls the Company within the meaning of either Section 15 of the 
Securities Act or Section 20 of the Exchange Act to the same extent as the 
foregoing indemnity from the Company to such Holder, but only with respect to 
information relating to such Holder furnished in writing by such Holder 
expressly for use in any Registration Statement, Prospectus or preliminary 
prospectus.  In no event, however, shall the liability hereunder of any 
selling Holder of Registrable Securities be greater than the dollar amount of 
the proceeds received by such Holder upon the sale of the Registrable 
Securities giving rise to such indemnification obligation.

          In case any action or proceeding shall be brought against the 
Company or its directors or officers or any such controlling person, in 
respect of which indemnity may be sought against a Holder of Registrable 
Securities, such Holder shall have the rights and duties given the Company 
and the Company or its directors or officers or such controlling person shall 
have the rights and duties given to each Holder by Sections 7(a) and 7(b) 
above.

          The Company shall be entitled to receive indemnities from 
underwriters, selling brokers, dealer managers and similar securities 
industry professionals participating in the distribution, to the same extent 
as provided above with respect to information so furnished in writing by such 
Persons specifically for inclusion in any Prospectus or Registration 
Statement.


                                      15



     (d)  CONTRIBUTION.

          If the indemnification provided for in this Section 7 is 
unavailable to an indemnified party under Section 7(a) or Section 7(c) above 
(other than by reason of exceptions provided in those Sections) in respect of 
any Claims referred to in such Sections, then each applicable indemnifying 
party, in lieu of indemnifying such indemnified party, shall contribute to 
the amount paid or payable by such indemnified party as a result of such 
Claims in such proportion as is appropriate to reflect the relative fault of 
the Company on the one hand and of the Holder on the other in connection with 
the statements or omissions which resulted in such Claims as well as any 
other relevant equitable considerations.  The amount paid or payable by a 
party as a result of the Claims referred to above shall be deemed to include, 
subject to the limitations set forth in Section 7(b), any legal or other fees 
or expenses reasonably incurred by such party in connection with 
investigating or defending any action or claim.

          The relative fault of the Company on the one hand and of the Holder 
on the other shall be determined by reference to, among other things, whether 
the Misstatement or alleged Misstatement relates to information supplied by 
the Company or by the Holder and the parties' relative intent, knowledge, 
access to information and opportunity to correct or prevent such Misstatement 
or alleged Misstatement.

          The Company and each Holder of Registrable Securities agree that it 
would not be just and equitable if contribution pursuant to this Section 7(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 above.

          Notwithstanding the provisions of this Section 7(d), an Indemnified 
Holder shall not be required to contribute any amount in excess of the amount 
by which (i) the total price at which the securities that were sold by such 
Indemnified Holder and distributed to the public were offered to the public 
exceeds (ii) the amount of any damages which such Indemnified Holder has 
otherwise been required to pay by reason of such Misstatement.

          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.

8.   EXCHANGE ACT REPORTING REQUIREMENTS

          From and after the date hereof, the Company shall (whether or not 
it shall then be required to do so) timely file such information, documents 
and reports as the Commission may require or prescribe under Section 13 or 
15(d) (whichever is applicable) of the Exchange Act.  In addition, the 
Company shall use all commercially reasonable efforts to file such other 
information, documents and reports, as shall hereafter be required by the 
Commission as a condition to the availability of Rule 144 under the 
Securities Act (or any successor provision) and the use of Form S-3.


                                      16



          From and after the date hereof, the Company shall forthwith upon 
reasonable request furnish any Holder of Registrable Securities (i) a written 
statement by the Company that it has complied with such reporting 
requirements, (ii) a copy of the most recent annual or quarterly report of 
the Company, and (iii) such other reports and documents filed by the Company 
with the Commission as such Holder may reasonably request in availing itself 
of an exemption for the sale of Registrable Securities without registration 
under the Securities Act pursuant to Rule 144 thereunder.

          The purpose of the foregoing requirements are (a) to enable any 
such Holder to comply with the current public information requirements 
contained in paragraph (c) of Rule 144 under the Securities Act (or any 
successor provision) and (b) to qualify the Company for the use of 
Registration Statements on Form S-3.

9.   REQUIREMENTS FOR PARTICIPATION IN UNDERWRITTEN OFFERINGS

          No Person may participate in any Underwritten Offering pursuant to 
a Registration hereunder unless such Person (a) agrees to sell such Person's 
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 questionnaires, powers of attorney, indemnities, 
underwriting agreements and other documents required under the terms of such 
underwriting arrangements

10.  SUSPENSION OF SALES

          Upon receipt of written notice from the Company that (i) a 
Registration Statement or Prospectus contains a Misstatement, or (ii) in the 
reasonable determination of the Company, there exists circumstances not yet 
disclosed to the public which would be required to be disclosed in such 
Registration Statement and the disclosure of which would be materially 
harmful to the Company, each Holder of Registrable Securities shall forthwith 
discontinue disposition of Registrable Securities until such Holder has 
received copies of the supplemented or amended Prospectus required by Section 
5(l) hereof, or until such Holder is advised in writing by the Company that 
the use of the Prospectus may be resumed, and, if so directed by the Company, 
such Holder shall 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 Registrable Securities current at the time of 
receipt of such notice.  The Company shall use all commercially reasonable 
efforts to minimize the length of such suspension of sales, provided, that 
the Company may require the suspension of sales for a period of ninety (90) 
days in the event that the disclosure of any circumstances, in the reasonable 
determination of the Company would be harmful in any material respect to the 
Company.  In no event, however, shall the aggregate period of time that the 
Company postpones the filing or declaration of effectiveness of any 
Registration Statement pursuant to Section 5, or suspends sales of 
Registrable Securities pursuant to Section 10 under any Registration 
Statement, taken together with all such other periods with respect to such 
Registrations Statement exceed, in the aggregate, ninety (90) days.


                                      17



11.  FUTURE REGISTRATION RIGHTS AGREEMENTS

          Except for an underwriting agreement between the Company and one or 
more professional underwriters of securities, the Company shall not agree to 
register any Equity Securities under the Securities Act unless such agreement 
specifically provides that:

          (a)  the Holder of such Equity Securities may not participate in any
Demand Registration without the consent of the Investors unless:

               (i)  the offering of the Registrable Securities is to be a Firm 
     Commitment Underwritten Offering and the managing underwriter concludes 
     that the public offering or sale of such Equity Securities would not 
     interfere with the successful marketing of all Registrable Securities 
     requested to be sold and

               (ii) the Holders of Registrable Securities shall have the right 
     to participate, to the extent they may request, in any Registration 
     Statement initiated under a Demand Registration right exercised by 
     Investors holding more than 50% of the Registrable Securities then 
     outstanding, except that if the managing underwriter of a public 
     offering made pursuant to such a Demand Registration limits the number 
     of shares of Common Stock to be sold, the participation of the Holders 
     of the Registrable Securities and the Holders of all other Common Stock 
     (other than the Equity Securities held by such Holder of Equity 
     Securities) shall be determined as set forth in Section 3 hereof.

          (b)  the Holder of such Equity Securities may not participate in 
any Piggyback Registration if the sale of Registrable Securities is to be 
underwritten unless, if the managing underwriter limits the total number of 
shares to be sold, the Holders of such Equity Securities and the Holders of 
Registrable Securities are entitled to participate in such underwritten 
distribution based on the order of priority set forth in Section 3 hereof, and

          (c)  all Equity Securities excluded from any Registration as a 
result of the foregoing limitations may not be publicly offered or sold for a 
period (not to exceed at least thirty (30) days prior to the effective date 
and sixty (60) days thereafter) that the managing underwriter reasonably 
determines is necessary in order to effect the underwritten public offering 
of Registrable Securities registered pursuant to this Agreement.

12.  TRANSFER OF REGISTRATION RIGHTS

          The rights of Holders of Registrable Securities hereunder may be 
transferred as permitted in the Purchase Agreement.  The Company shall be 
given written notice by the Holder at the time of any such transfer permitted 
by the Purchase Agreement stating the name and address of the transferee, 
including a writing by such transferee to the effect that such transferee 
agrees to by bound by the terms hereof and identifying the securities with 
respect to which the rights hereunder are being transferred.


                                      18



13.  MISCELLANEOUS

     (a)  REMEDIES.

          Each Holder of Registrable Securities, in addition to being 
entitled to exercise all rights provided herein, in the Purchase Agreement 
and granted by law, including recovery of damages, shall be entitled to 
specific performance of its rights under this Agreement.  The Company agrees 
that monetary damages would not be adequate compensation for any loss 
incurred by reason of a breach by it of the provisions of this Agreement and 
hereby agrees to waive the defense in any action for specific performance 
that a remedy at law would be adequate.

     (b)  NO INCONSISTENT AGREEMENTS.

          The Company shall 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 of Registrable Securities in this 
Agreement or otherwise conflicts with the provisions hereof.

          Other than as disclosed on Schedule A attached hereto, the Company 
has not previously entered into any agreement with respect to its securities 
granting any "piggy back" registration rights to any Person.  The Company 
represents and warrants to the Investors that, except as set forth in this 
Agreement and the GE Registration Rights Agreement, as of the date hereof, 
there are no outstanding "demand" registration rights with respect to the 
Company's securities.  The rights granted to the Holders of Registrable 
Securities 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 
such agreements.

     (c)  AMENDMENTS AND WAIVERS.

          The provisions of this Agreement, including the provisions of this 
sentence, may not be amended, modified or supplemented, and waivers or 
consents to departures from the provisions hereof may not be given unless the 
Company has obtained the written consent of General Electric Company, a New 
York corporation (but such consent of General Electric Company shall only be 
necessary if, at the time such consent is sought, GE owns GE Registrable 
Securities) and of Investors holding more than 50% of the Registrable 
Securities then outstanding (on behalf of themselves and all permitted 
assignees who are Holders of Registrable Securities).  The foregoing 
notwithstanding, a waiver or consent to departure from the provisions hereof 
that relates exclusively to the rights of Holders of shares of Registrable 
Securities whose shares are being sold pursuant to a Registration Statement 
and that does not directly or indirectly affect the rights of other Holders 
of shares of Registrable Securities may be given by the Holders of a majority 
of the shares of Registrable Securities being sold.

     (d)  NOTICES.

          All notices and other communications provided for or permitted 
hereunder shall be made in writing by hand-delivery, registered first-class 
mail, telex, facsimile, or air courier guaranteeing overnight delivery:
