     all financial statements, proxy statements, reports and other
     communications which the Company sends to its stockholders, and copies of
     all registration statements and all regular, special or periodic reports

accounting principles or practices, financial statement disclosure, or auditing
scope or procedure. In its notice, the Company shall state whether the change of
accountants was recommended or approved by the Board of Directors or any

otherwise serving as a director.

          (e) Notwithstanding any other provision of this Agreement, the
covenants and agreements of the Company set forth in this Section 7.5 shall

below) of (i) Preferred Conversion Shares or Note Conversion Shares and (ii)
Warrant Shares or as the Purchasers may otherwise agree), all (or any part) of
the percentage (the "Purchasers' Share") of New Securities (as hereinafter
defined), corresponding to the percentage of outstanding Common Stock and Common
Stock issuable upon exercise, conversion or exchange of convertible securities,
options, rights and warrants then outstanding (excluding convertible securities,
options, rights of warrants, other than the Preferred Stock or Convertible Notes
and Warrants, which have a conversion price or exercise price in excess of the

Shares and (ii) Warrant Shares held (assuming conversion of all Preferred Stock
or Convertible Notes and exercise of all Warrants as of the date of the
commencement of the Exercise Period defined below) by them, which the Company
may, from time to time, sell and issue, provided that the Purchasers' Share
shall be calculated immediately before the sale or issuance of New Securities.
Each Purchaser, which shall have exercised its right hereunder in full, shall

non-purchasing Purchaser fails to exercise its right hereunder to purchase its
pro rata share of the

                                       17
   25



Purchasers' Share of New Securities. This right of first refusal shall be
subject to the following provisions:

          (a) "New Securities" shall mean any capital stock of the Company
whether now authorized or not and any securities convertible into or
exchangeable or exercisable for capital stock of the Company; provided that, the
term "New Securities" does not include (i) the Securities and the securities
issued upon conversion, exercise or exchange of any of the Securities purchased
under this Agreement, securities issued upon exercise of the Warrants or other
currently outstanding Derivative Securities; (ii) securities offered pursuant to
an effective registration statement under the Securities Act; (iii) securities
issued pursuant to the acquisition of another corporation by the Company by
merger, purchase of substantially all the assets or other reorganization
resulting in the ownership by the Company of not less than a majority of the

exercise thereof) and approved by the Board of Directors; and (vi) securities
issued as a result of any stock split, combination, dividend, distribution,
reclassification, exchange or substitution.

          (b) In the event the Company proposes to undertake an issuance of New
Securities, it shall give each Purchaser written notice of its intention,
describing the type of New Securities, the price and the general terms upon
which the Company proposes to issue the same. Each Purchaser shall have fifteen
(15) business days from the date of receipt of any such notice (the "Exercise
Period") to agree to purchase all or a portion of its pro rata share of the
Purchasers' Share of such New Securities for the price and upon the general
terms specified in the notice by giving written notice to the Company, which
notice shall state the quantity of New Securities to be purchased by it and the
date on which such purchase shall occur (which shall be not less than ten (10)
nor more than fifteen (15) business days after the date of receipt of such
notice).

          (c) In the event the Purchasers' right of first refusal is not
exercised within the Exercise Period and after the expiration of the five (5)
business day period for the exercise of the over-allotment provisions of this
Section 7.7 as to any or all of the New Securities (the "Remaining New
Securities"), the Company shall have one hundred and twenty (120) days after the
expiration of the Exercise Period (the "Offering Period") to sell or enter into
an agreement (pursuant to which the sale of the Remaining New Securities covered
thereby shall be closed, if at all, within ninety (90) days from the date of
said agreement) to sell the Remaining New Securities at a price and upon general
terms no more favorable to the purchasers thereof than specified in the
Company's notice. In the event the Company has not sold within the Offering
Period or entered into an agreement to sell the Remaining New Securities within
the Offering

                                       18
   26



Period (or sold and issued Remaining New Securities in accordance with the
foregoing within ninety (90) days from the date of said agreement), the Company
shall not thereafter issue or sell any New Securities, without first offering to
the Purchasers the right to purchase their pro rata share of the Purchasers'
Share thereof, in the manner provided above.

          (d) The right of first refusal granted under this Agreement shall
expire on the seventh anniversary of the Closing Date.

          (e) The right of first refusal set forth in this Section 7.7 is
nonassignable, except that such right is assignable by a Purchaser to one or
more of its Affiliates (as such term is defined in Rule 144 under the Securities
Act) in connection with a transfer of Securities and in accordance with Section
17.3.

          (f) Notwithstanding any other provision of this Agreement, the
covenants and agreements of the Company set forth in this Section 7.7 shall
remain in full force and effect until the earlier of (i) the seventh anniversary
of the Closing Date or (ii) such time as the Purchasers cease to be the holders,
in the aggregate, of shares of Common Stock or Securities convertible into,
exercisable for or representing at least five percent (5% ) of the aggregate
number of shares of Common Stock outstanding or issuable upon the conversion,
exchange or exercise of any convertible securities, options, rights or warrants
outstanding.

     7.8. RULE 144A INFORMATION. In the event the Company is not subject to
Section 13 or 15(d) of the Securities and Exchange Act of 1934 (the "Exchange
Act"), the Company will (i) make available, upon request, to any holder of
Securities and any prospective purchaser thereof designated by such a holder,
upon the request of such holder or prospective purchaser, the information
required to be provided to such holder or prospective purchaser by Rule
144A(d)(4) under the Securities Act and (ii) update such information from time
to time in order to prevent such information from becoming false and misleading
and will take such other actions as are necessary to ensure that the safe harbor
exemption from the registration requirements of the Securities Act under Rule
144A is and will be available for resales of the Securities conducted in
accordance with Rule 144A.

     7.9. POST-CLOSING REVIEW. Within ninety (90) days following the Closing
Date, the Company shall deliver to each Purchaser a certificate of the President
of the Company stating that the proceeds from the sale of the Preferred Stock,
the Subordinated Notes and the Warrants were used for the purpose specified in
Section 7.6 hereof.

     7.10. FURTHER ASSURANCES. From time to time the Company shall execute and
deliver to the holders of Securities such other instruments, certificates,
agreements and documents and take such other action and do all other things as
may be reasonably requested by such holders in order to implement or effectuate
the terms and provisions of this Agreement.

(i) the accrued and unpaid interest on each Convertible Note, if outstanding (to

or affecting creditors' rights and to general principles of equity, (ii) the New
Warrants are exercisable for the New Warrant Securities or other cash or

of Convertible Notes or Subordinated Notes to be redeemed shall surrender such

Subordinated Note or Holder or Company Redemption Notice, as the case may be,
and thereupon the outstanding principal and accrued interest on such Notes shall
be payable to the order of the person whose name appears on such Notes as the
owner thereof and each surrendered Note shall be canceled. In the event less
than all the principal on any Subordinated Note is redeemed, a new Subordinated
Note shall be issued reflecting the unpaid principal thereon. From and after the
redemption date, unless there shall have been a default in the payment of the
redemption price or issuance of New Warrants, all rights of the holders of the
Notes designated for redemption as holders of Notes of the Company (except the
right to receive the redemption price without interest and (if applicable) the
New Warrants upon surrender of their Notes) shall cease with respect to such
Notes, and such Notes shall not thereafter be transferred on the books of the
Company or be deemed to be outstanding for any purpose whatsoever.

Registration. The Conversion Demand Registration and the Warrant Demand
Registration shall be collectively known as the "Demand Registrations".

          (c) UNDERWRITTEN OFFERING. If the Holders initiating the registration

          (d) COOPERATION BY THE COMPANY. The Company shall and shall cause its
management to cooperate fully and to use its best efforts to effect the
registration of Registrable Securities and the sale of Registrable Securities

provided, however, in the event that the Company reasonably determines, that it
is not then eligible to use a registration statement on Form S-3 or other short
form registration statement under the Securities Act, and the Company furnishes
to the Holders a certificate of an executive officer of the Company stating that

and reasonable presentations in respect of the Company at a reasonable number of

Demand Registration. A registration will not count as a Demand Registration
until it has become effective. A registration will count as a Demand
Registration after it has become effective unless such registration statement
has been withdrawn prior to the sale of all Registrable Securities covered
thereby at the request of the Holders (other than as a result of (i) an action
or omission to act by the Company which adversely affects the market for, or the
price of, Registrable Securities or (ii) a material adverse change in the
business, financial condition or prospects of the Company occurring after the
effective date of the registration statement); provided, however, that in any
event the Company will pay all Registration Expenses in connection with any
registration so initiated; provided, further, however, that the holders of
Registrable Securities may withdraw a registration without having it count as a
Demand Registration only once in any twelve month period.

          (f) PRIORITY ON DEMAND REGISTRATIONS. 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 requested to
be included exceeds the number which can be sold in such offering, the Company
will include in such registration such number of shares, which in the opinion of
such underwriters, may be sold, allocated among the Holders electing to

                                      31
   39



participate pro rata in accordance with the amounts of securities requested to
be so included by the respective Holders.

     10.4. PIGGYBACK REGISTRATIONS.

           (a) RIGHT TO PIGGYBACK. Whenever the Company proposes to register any
of its securities (other than pursuant to a Demand Registration) and the
registration form to be used may be used for the registration and contemplated
disposition of Registrable Securities (a "Piggyback Registration"), the Company
will give prompt written notice to all Holders of Registrable Securities of its
intention to effect such a registration so that such notice is received by each
Holder at least twenty (20) days before the anticipated filing date. The Company
will include in such registration all Registrable Securities with respect to
which the Company has received written requests for inclusion therein within ten
(10) calendar days after the receipt of the Company's notice; provided that the
Company shall have the right to postpone or withdraw any registration effected
pursuant to this Section 10.4 without obligation to any Holder.

           (b) PIGGYBACK EXPENSES. The Registration Expenses of the Holders of
Registrable Securities in connection with a Piggyback Registration will be paid
by the Company.

           (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 that in their opinion the
distribution of the Registrable Securities to be included in the Piggyback
Registration concurrently with the securities being registered on behalf of the
Company would materially adversely affect the distribution of such securities by
the Company, the Company will include in such registration (i) first, the
securities the Company proposes to sell, (ii) second, the holders of Registrable
Securities who have requested registration and other holders of shares of Common
Stock entitled, pursuant to agreements in effect on the date of this Agreement,
to include shares of Common Stock in such registration shall participate in the
underwriting pro rata based upon their total ownership of shares of Common Stock
of the Company on an as if-converted basis; and (iii) third, any other
securities requested to be included in such registration.

           (d) PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback Registration
is an underwritten secondary registration initiated by holders of the Company's
securities other than the holders of the Registrable Securities, and the
managing underwriters advise the Company in writing that in their opinion the
distribution of the Registrable Securities in a Piggyback Registration
concurrently with the securities being registered on behalf of holders of the
Company's securities would materially adversely affect the distribution of such
securities, 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 holders of Registrable Securities who have
requested registration and other holders of shares of Common Stock entitled,
pursuant to agreements in effect on the date of this Agreement, to include
shares of Common Stock in such registration shall participate in the
underwriting pro rata based upon their total ownership of shares of Common Stock
of the

                                       32
   40



Company on an as if-converted basis, and (iii) third, any other securities
requested to be included in such registration.

           (e) OTHER RESTRICTIONS. In connection with any registration under
this Section 10.4 involving an underwriting, the Company shall not be required
to include any Registrable Securities in such underwriting unless the holders
thereof accept the terms of the underwriting as agreed upon between the Company,
the parties initiating the registration (if other than the Company) and the
underwriters. The Company hereby agrees that if it has previously filed a
registration statement with respect to Registrable Securities pursuant to
Section 10.3 or pursuant to this Section 10.4, and if such previous registration
has not been withdrawn or abandoned (for purposes of this Agreement, a
registration statement which has been filed but has not been declared effective
within six (6) months of the date of filing shall be deemed 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 (except on Form S-8 or any other similar
form for employee benefit plans), whether on its own behalf or at the request of
any holder or holders of such securities, until (i) six (6) months has elapsed
from the effective date of such previous registration or (ii) sooner if all
Registrable Securities included in such previous registration have been sold.

           (f) TRIUMPH REGISTRATION. The provisions of this Section 10.4 shall
not be applicable to the registration statement on Form S-3 which the Company is
required to file on or about June 1, 1998 pursuant to the Securities Purchase
Agreement dated as of January 31, 1997, as amended, by and among the Company,
Triumph-Connecticut Limited Partnership and the other purchasers named therein.

     10.5. HOLDBACK AGREEMENTS.

           (a) Each Holder of Registrable Securities which is a party to this
Agreement agrees not to effect any public sale or distribution of equity
securities of the Company, or any securities convertible into or exchangeable or
exercisable for such securities, during the period commencing seven (7) days
prior to and ending ninety (90) days after the effective date of any
underwritten Demand Registration or any underwritten Piggyback Registration
(except as part of such underwritten registration or with the consent of the
managing underwriter). The commencement of such period shall be determined in
good faith by the managing underwriter and advised to the Holders, provided that
the executive officers and directors of the Company and each of the holders
(with which any officer of director of the Company is affiliated) of five
percent (5%) or more of the then outstanding shares of Common Stock on a fully
diluted basis (including for this purpose all shares issuable upon the
conversion, exchange or exercise of Derivative Securities) shall have entered
into similar agreements.

           (b) The Company agrees (i) 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 period commencing
seven (7) days prior to and ending ninety (90) days after

                                       33
   41



the effective date of any underwritten Demand Registration or any underwritten
Piggyback Registration in which a Holder participates (except (A) as part of
such underwritten registration, (B) with the consent of the managing underwriter
of such underwritten registration or (C) pursuant to registrations on Form S-8
or any other similar form for employee benefit plans), and (ii) to use its
reasonable best efforts to cause each officer or director of the Company or
holder of greater than 5% of its equity securities, or any securities
convertible into or exchangeable or exercisable for such securities with which
any officer or director of the Company is affiliated, to agree not to effect any
public sale or distribution of any such securities during such period to the
extent timely requested by the underwriters (except as part of such underwritten
registration, if otherwise permitted, or with the consent of the managing
underwriter). The commencement of such period shall be determined in good faith
by the managing underwriter.

     10.6. REGISTRATION PROCEDURES. Whenever the Holders of Registrable
Securities have requested that any Registrable Securities be registered pursuant
to this Article X, the Company will promptly 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 reasonably possible:

           (a) prepare and file with the SEC a registration statement with
respect to such Registrable Securities, and 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 each of the Holders of Registrable Securities
covered by such registration and counsel selected by such Holders, copies of all
such documents proposed to be filed, which documents will be subject to their
prior review and reasonable approval and such review shall also be completed as
expeditiously as reasonably possible);

           (b) prepare and file with the SEC 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 the period
set forth in Section 10.6(l) hereof and comply with the provisions of the
Securities Act with respect to the disposition of all Registrable Securities
covered by such registration statement during such period in accordance with the
intended methods of disposition by the Holders thereof set forth in such
registration statement;

           (c) furnish to each Holder of Registrable Securities covered by such
registration 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 Holder may reasonably request in order to facilitate the disposition of
such Registrable Securities;

           (d) use its best efforts to register or qualify Registrable
Securities covered by such registration under such other securities or blue sky
laws of such jurisdictions as any Holder reasonably requests and do any and all
other acts and things which may be reasonably necessary or advisable to enable
the Holders thereof to consummate the disposition in such jurisdictions of the

                                       34
   42



Registrable Securities as requested by such Holders (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 Holder of Registrable Securities covered by such
registration, at any time when a prospectus relating thereto is required to be
delivered under the Securities Act, of the happening of any event of which the
Company has, or should have, knowledge as a result of which the prospectus
included in such registration statement (or any document incorporated therein by
reference) contains an untrue statement of a material fact or omits to state any
fact necessary to make the statements therein not misleading, and the Company
will prepare a supplement or amendment to such prospectus (or any document
incorporated therein by reference) as soon as practicable thereafter so that
such prospectus (or any document incorporated therein by reference) will not
contain an untrue statement of a material fact or omit to state any fact
necessary to make the statements therein not misleading;

           (f) cause all such Registrable Securities covered by such
registration to be listed on each securities exchange or automated quotation
system on which similar securities issued by the Company are then listed or
quoted;

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

           (h) enter into such customary agreements (including an underwriting
agreement) 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;

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

           (j) obtain a "comfort letter" from the Company's independent public
accountants in customary form and covering such matters of the type customarily
covered by comfort letters and opinions of counsel from the Company's counsel in
customary form and covering such matters of the type customarily covered in a
public issuance of securities, in each case addressed to the Holders and any
underwriters;

                                       35

   43



           (k) otherwise use its best efforts to comply with all applicable
rules and regulations of the SEC and make generally available to its security
holders, earnings statements satisfying the provisions of Section 11(a) of the
Securities Act, no later than forty five (45) days after the end of any twelve
(12) month period (i) commencing at the end of any fiscal quarter in which an
applicable registration statement covering Registrable Securities becomes
effective and (ii) 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 twelve (12) month periods; and

           (l) keep each registration statement effective for one year from the
date of its effectiveness or for such period in excess of one year as to which
the Holders shall agree to pay all Registration Expenses in connection with
keeping such registration statement effective.

           If the Company has delivered preliminary or final prospectuses to the
selling Holders and after having done so the prospectus is amended to comply
with the requirements of the Securities Act, the Company shall immediately
notify the selling Holders and, if requested, the selling Holders shall
immediately cease making offers of Registrable Securities and return all
prospectuses to the Company. The Company shall promptly provide the selling
Holders with revised prospectuses and, following receipt of the revised
prospectuses, the selling Holders shall be free to resume making offers of the
Registrable Securities. The Company shall be obligated to keep the Registration
Statement effective for a period of additional days equal to the number of days
during which the Holders were required to cease making offers pursuant to this
paragraph.

     10.7. INDEMNIFICATION.

           (a) In the event of any registration of the Registrable Securities,
the Company will indemnify each Seller of Registrable Securities (a "Seller"),
each Seller's officers, directors and partners, and each person controlling such
Seller (within the meaning of the Securities Act and the rules and regulations
thereunder), against all claims, losses, damages, liabilities (or actions in
respect thereof) and expenses arising out of or based on any untrue or alleged
untrue statement of a material fact contained in any registration statement
under which such Registrable Securities were registered or, prospectus or
preliminary prospectus contained in such registration statement or any amendment
or supplement to such registration statement or any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, or any violation by the Company of
the Securities Act, any rule or regulation thereunder and relating to action or
inaction required of the Company in connection with any such registration,
qualification or compliance, and will reimburse each such Seller, such Seller's
officers, directors and partners, and each person controlling such Seller for
any legal and any other expenses incurred in connection with investigating or
defending any such claim, loss, damage, liability or action, provided, that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage, liability or action or expense arises out of or is based on any
untrue or alleged untrue statement or omission or alleged omission of material
fact based upon written information



                                       36
   44



furnished to the Company by or on behalf of such Seller and stated to be
specifically for use therein.

           (b) Each Seller will, severally and not jointly, if Registrable
Securities held by it are included in the securities as to which such
registration is being effected, indemnify the Company, each of the Company's
directors and officers and each person who controls the Company (within the
meaning of the Securities Act and the rules and regulations thereunder), each
other Seller whose securities are included in such registration and each of such
other Seller's officers, directors and partners and each person controlling such
other Seller, against all claims, losses, damages and liabilities (or actions in
respect thereof) and expenses arising out of or based on any untrue or alleged
statement of a material fact contained in any such registration statement,
prospectus or preliminary prospectus or any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse the Company, its
officers and directors, each person controlling the Company, each other Seller,
and such other Seller's officers, directors, partners and control persons for
any legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action, in
each case to the extent, but only to the extent, that such untrue or alleged
statement or omission or alleged omission is made in such registration
statement, prospectus or preliminary prospectus in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
such Seller and stated to be specifically for use therein.

           (c) Each party entitled to indemnification under this Section 10.7
(an "Indemnified Party") shall give notice to the party required to provide
indemnification (an "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom provided that counsel for the Indemnifying Party,
who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be reasonably satisfactory to the Indemnified Party, and the
Indemnified Party may participate in such defense at its own expense, and
provided, further, that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Article X, except to the extent that the Indemnifying Party's ability
to conduct such defense shall have been materially prejudiced by such failure.
To the extent that, in the opinion of counsel to the Indemnified Party, a
conflict of interest exists between an Indemnified Party and the Indemnifying
Party such that representation of such Indemnified Party by counsel for the
Indemnifying Party would be inappropriate, then such Indemnified Party shall be
entitled to separate counsel at the expense of the Indemnifying Party; provided
that in no event shall the Indemnifying Party be required to pay the expense of
more than one such separate counsel per jurisdiction. Each Indemnified Party
shall furnish such information regarding itself or the claim in question as an
Indemnifying Party may reasonably request in writing and as shall be reasonably
required in connection with the defense of such claim and any litigation
resulting therefrom.

     10.8. INFORMATION BY HOLDERS. Each Seller of Registrable Securities
included in any registration shall furnish to the Company such information
regarding such Seller and the distribution proposed by such Seller as the
Company may reasonably request in writing and as shall be reasonably required in
connection with any registration, qualification or compliance referred to in
this Article X.

     10.9. LIMITATIONS ON REGISTRATION OF ISSUES OF SECURITIES. From and after
the date of this Agreement, the Company shall not enter into any agreement with
any holder or prospective holder of any securities of the Company giving such
holder or prospective holder the right to require the Company to register any
securities of the Company more favorable than the rights granted under this
Article X, unless such action is consented to by a majority of the outstanding
Warrant Shares held by the Purchasers (and their assignees) and issuable to them
(or such assignees) upon exercise of the Warrants held by them and a majority of
the Conversion Shares held by the Purchasers (and their assignees) and issuable
to them (or such assignees) upon conversion of the Convertible Notes held by
them. Any right given by the Company to any holder or prospective holder of the
Company's securities in connection with the registration of securities shall be
conditioned such that it shall be consistent with the provisions of this Article
X and with the rights of the Holders provided in this Agreement and such holder
or prospective holder agrees that its registration rights shall be consistent
the terms of this Article X.

     10.10. RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC which may permit the sale of the
Restricted Securities to the public without registration, the Company agrees, so
long as it is required to file reports with the SEC pursuant to the Exchange
Act, to:

            (a) make and keep public information available as those terms are
understood and defined and interpreted in and under Rule 144 under the
Securities Act;

            (b) use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the United States Securities Exchange Act of 1934, as amended
(the "Exchange Act"); and

            (c) so long as the Purchasers own any Restricted Securities, furnish
to such Holders forthwith upon request a written statement by the Company as to
its compliance with the reporting requirements of Rule 144 and the Exchange Act,
a copy of the most recent annual or quarterly report of the Company, and such
other reports and documents so filed as such Holder may reasonably request in
availing itself of any rule or regulation of the SEC allowing such Holder to
sell any such securities without registration.

     10.11. SELECTION OF UNDERWRITERS. If any Demand Registration is an
underwritten offering, the Holders of a majority of the Registrable Securities
included in such registration shall have the right to select the investment
banker(s) and manager(s) to administer the offering, subject to the approval of
the Company (which approval will not be unreasonably withheld).

expenses, reimbursement and indemnification obligations, and all other amounts
payable under or in respect of indebtedness of the Company for money borrowed

           (a) The Company agrees, and each holder of Notes by his acceptance
thereof likewise agrees, that the payment of the principal of, premium, if any,

subordinated and junior in right of payment, to the extent and in the manner
provided in this Article XI to the prior payment in full of all Senior
Indebtedness whether outstanding on the date hereof or hereafter created,
incurred, assumed or guaranteed. A Payment or Distribution shall include any
asset of any kind or character, and may consist of cash, securities or other
property, by set-off or otherwise, and shall include, without limitation, any
purchase, redemption or other acquisition of the Notes or other making of any
deposit of funds or securities pursuant to this Agreement.

           (b) The Senior Indebtedness shall continue to be Senior Indebtedness
and entitled to the benefit of these subordination provisions irrespective of
any amendment, modification or waiver or any term of any instrument relating to
refinancing of the Senior Indebtedness.

subject to the provisions of this Article XI so far as they may be applicable
thereto.

their expressed maturity because of the occurrence of an Event of Default
hereunder or any required redemption of the Notes, the Company will give prompt
notice in writing of such happening to the holders of Senior Indebtedness.

     11.3. COMPANY NOT TO MAKE PAYMENTS WITH RESPECT TO NOTES IN CERTAIN
           CIRCUMSTANCES.

           (a) No Payment or Distribution shall be made by the Company on
account of the Notes, whether upon stated maturity, upon prepayment or
acceleration, or otherwise, or on account of the purchase, redemption or other
acquisition of Notes, whether upon stated maturity, prepayment, acceleration, or
otherwise, if there shall have occurred and be continuing a default with respect
to any Senior Indebtedness permitting the acceleration thereof or with respect
to the payment of any Senior Indebtedness and (i) such default is the subject of
a judicial proceeding or (ii) notice of such default in writing or by telegram
has been given to the Company by any holder or holders of any Senior
Indebtedness, unless and until the Company shall have received written notice
from such holder or holders that such default or event of default shall have
been cured or waived or shall have ceased to exist.

           (b) Upon any payment by the Company or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding up or liquidation or reorganization of
the Company, whether voluntary or involuntary, or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become due upon all
Senior Indebtedness shall first be paid in full in cash, or payment thereof in
cash provided for to the satisfaction of the holders thereof, before any Payment
or Distribution is made on account of the Notes; and (subject to the power of a
court of competent jurisdiction to make other equitable provision, which shall
have been determined by such court to give effect to the rights conferred in
this Article upon the Senior Indebtedness and the holders thereof with respect
to the Notes or the holders thereof, by a lawful plan or reorganization or
readjustment under applicable law) upon any such dissolution or winding up or
liquidation or reorganization, any Payment or Distribution by the Company or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the holders of the Notes would be entitled
except for the provisions of this Article, shall be paid by the Company or by
any receiver, trustee in bankruptcy, liquidating trustee, agent or other person
making such Payment or Distribution directly to the holders of Senior
Indebtedness of the Company or their representative or representatives, or to
the trustee or trustees under any indenture pursuant to which any instruments
evidencing any Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay all Senior Indebtedness in
full, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Indebtedness, before any Payment or Distribution is made
to the Holders of the Notes.

           (c) In the event that, notwithstanding the foregoing, any Payment or
Distribution by the Company of any kind or character, whether in cash, property
or securities, prohibited by the foregoing, shall be received by the holders of
the Notes before all Senior Indebtedness is paid in full, or provision is made
for such payment to the satisfaction of the holders thereof, and if such fact
shall then have been or thereafter be made known to such holders, then and in
such event such Payment or Distribution shall be paid over or delivered to the
holders of Senior Indebtedness or their representative or representatives, or to
the trustee or trustees under any

                                       40
   48



indenture pursuant to which any instruments evidencing any Senior Indebtedness
may have been issued, as their respective interests may appear, for application
to the payment of all Senior Indebtedness remaining unpaid to the extent
necessary to pay all Senior Indebtedness in full, after giving effect to any
concurrent Payment or Distribution to or for the holders of such Senior
Indebtedness, and, until so delivered, the same shall be held in trust by any
holder of a Note as the property of the holders of Senior Indebtedness.

           (d) The holders of Senior Indebtedness may, at any time and from time
to time, without the consent of or notice to the holders of the Notes, without
incurring responsibility to the holders of the Notes and without impairing or
releasing the obligations of the holders of the Notes hereunder to the holders
of Senior Indebtedness: (i) change the manner, place or terms of payment or
change or extend the time of payment of, or renew or alter, Senior Indebtedness,
or otherwise amend in any manner Senior Indebtedness or any instrument
evidencing the same or any agreement under which Senior Indebtedness is
outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any
person liable in any manner for the collection of Senior Indebtedness; and/or

other person.

     11.4. SUBROGATION OF NOTES.

           (a) Subject to the payment in full in cash of all amounts then due
(whether by acceleration of the maturity thereof or otherwise) on account of all
Senior Indebtedness at the time outstanding, the holders of the Notes shall be
subrogated to the rights of the holders of Senior Indebtedness to receive
Payments or Distributions of cash, property or securities of the Company
applicable to the Senior Indebtedness until the principal of (and premium, if
any) and interest on the Senior Indebtedness shall be paid in full; and, for the
purposes of such subrogation, no Payments or Distributions to the holders of
Senior Indebtedness to which the holders of the Notes would be entitled except
for the provisions of this Article, and no payments over pursuant to the
provisions of this Article to the holders of Senior Indebtedness by holders of
the Notes, shall, as between the Company, the Company's creditors other than
holders of Senior Indebtedness, and the holders of the Notes, be deemed to be a
payment by the Company to or on account of the Senior Indebtedness. It is
understood that the provisions of this Article are and are intended solely for
the purpose of defining the relative rights of the holders of the Notes, on the
one hand, and the holders of Senior Indebtedness, on the other hand.

           (b) Nothing contained in this Article or elsewhere in this Agreement
or in the Notes is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Indebtedness, and the holders of the
Notes, the obligation of the Company, which is absolute and unconditional, to
make the Payment or Distribution on account of the Notes as and when the same
shall become due and payable in accordance with their terms, or is intended to
or shall affect the relative rights of the holders of the Notes and creditors of
the Company other than the holders of Senior Indebtedness, nor shall anything
herein or therein prevent the holder of any Note from exercising all remedies
otherwise permitted by applicable law upon default under this

                                       41
   49



Agreement, subject to the rights, if any, under this Article of the holders of
Senior Indebtedness in respect of cash, property or securities of the Company
received upon the exercise of any such remedy.

           (c) Upon any payment or distribution of assets of the Company
referred to in this Article, the holders of the Notes shall be entitled to rely
upon any order or decree made by any court of competent jurisdiction in which
any dissolution, winding up, liquidation or reorganization proceedings are
pending, or certificate of the receiver, trustee in bankruptcy, liquidating
trustee, agent or other person making such payment or distribution, delivered to
the holders of the Notes, for the purpose of ascertaining the persons entitled
to participate in such distribution, the holders of Senior Indebtedness and
other indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.

     11.5. NOTICES. The Company shall give prompt written notice to the holders
of the Notes of any facts known to it which would prohibit the making of any
payment of moneys to holders in respect of the Notes pursuant to the provisions
of this Article.

     11.6. NO IMPAIRMENT OF SUBORDINATION. No right of any present or future
holder of any Senior Indebtedness to enforce subordination as herein provided
shall at any time in any way be prejudiced or impaired by any act or failure to
act on the part of the Company or the holder of any of the Notes or by any act,
or failure to act, in good faith, by any such holder of Senior Indebtedness, or
by any noncompliance by the Company or the holder of any of the Notes with the
terms, provisions and covenants of this Agreement or the Notes, regardless of
any knowledge thereof which any such holder may have or otherwise be charged
with.

     11.7. ARTICLE XI NOT TO PREVENT EVENTS OF DEFAULT. The failure to make a
payment on account of principal of (premium, if any) or interest on the Notes by
reason of any provision in this Article XI shall not be construed as preventing
the occurrence of an Event of Default.

     11.8. AMENDMENT TO ARTICLE XI. The terms of this Article XI may be amended,
with the consent of holders of at least eighty percent (80%) in principal amount
of the Subordinated Notes and holders of at least eighty percent (80%) of the
shares of Preferred Stock (or holders of at least eighty percent (80%) in
principal amount of the Convertible Notes, if issued), which consent shall not
be unreasonably withheld, to conform to the commercially reasonable requirements
of a financial institution which proposes to provide Borrowed Money Indebtedness
to the Company to the extent permitted by Section 8.1. The Company shall not be
charged a fee for providing such consent.

                                   ARTICLE XII
                       CONVERSION OF THE CONVERTIBLE NOTES
 
     12.1. CERTAIN DEFINITIONS. For purposes of this Article XII, the following
terms shall have the meanings set forth in this Section 12.1.

           AFFILIATE means any Person controlling, controlled by or under common
control with any other Person. For purposes of this definition, "CONTROL"
(including "CONTROLLED BY" and "UNDER COMMON CONTROL WITH") means the
possession, directly or indirectly, of the power to direct or cause the
direction of the management and policies of such Person, whether through the
ownership of voting securities or otherwise.

           "CLOSING PRICE" shall mean with respect to the shares of Common Stock
of the Company on any day, (i) the last reported sales price regular way or, in
case no such reported sale takes place on such day, the average of the reported
closing bid and asked prices regular way, in either case on the Nasdaq National
Market, or (ii) if the shares of Common Stock are not listed or admitted to
trading on the Nasdaq National Market, the last reported sales price regular
way, or in case no such reported sale takes place on such day, the average of
the reported closing bid and asked prices regular way, on the principal national
securities exchange on which the shares of Common Stock are listed or admitted
to trading, or (iii) if the shares of Common Stock are not listed or admitted to
trading on the Nasdaq National Market or any national securities exchange, the
average of the closing bid and asked prices in the over-the-counter market as
furnished by any New York Stock Exchange, Inc. member firm selected from time to
time by the Company for that purpose, or (iv) if such prices in the
over-the-counter market are not available, the fair market value set by, or in a
manner established by, the Board of Directors of the Company in good faith.

           "CURRENT MARKET PRICE" per share of Common Stock at any date herein

consecutive trading days commencing forty-five (45) days before such date.

           "PERSON" shall mean any individual, corporation, association,
company, business trust, partnership, joint venture, joint-stock company,
limited liability company, trust, unincorporated organization or association or
government or any agency or political subdivision thereof.

     12.2. RIGHT OF CONVERSION; CONVERSION PRICE. Any holder of Convertible
Notes shall have the right, at its option, at any time to convert, subject to
the terms and provisions of this Article XII, such Convertible Notes into shares
of Common Stock upon surrender of the Convertible Notes to be so converted,
accompanied by written notice of conversion duly executed, to the Company, and,
if so required by the Company, duly endorsed to the Company or in blank or
accompanied by proper instruments of transfer to the Company or in blank. The

                                       43
   51



Convertible Notes shall be convertible at the conversion price of $4.75 per
share of Common Stock, or in case an adjustment of such price has taken place
pursuant to the provisions of this Article XII, the price as last adjusted (such
price or adjusted price being referred to herein as the "Conversion Price"). The
number of shares of Common Stock issuable upon such conversion shall be equal to
(a) the aggregate principal amount of the Convertible Note to be converted plus
accrued but unpaid interest thereon to the date of conversion, divided by (b)
the Conversion Price. Whenever the Conversion Price in effect shall be adjusted
pursuant to this Article XII, the Company shall promptly provide to each holder
of Convertible Notes a notice stating that the Conversion Price has been
adjusted and setting forth the adjusted Conversion Price, which notice shall be
signed on behalf of the Company by the President and the Chief Financial Officer
of the Company and shall set forth in reasonable detail a calculation to the
nearest cent of the Conversion Price, the method of calculation and the facts
requiring such adjustment.

     12.3. ISSUANCE OF SHARES ON CONVERSION. The Company will as soon as
practicable after the surrender, as herein provided, deliver to the holder or to
its nominee or nominees, certificates for the number of full shares of Common
Stock to which it shall be entitled as aforesaid, together with a cash
adjustment of any fraction of a share as hereinafter provided, if not evenly
convertible, and, if less than the entire principal amount of the Convertible
Note is converted, a new Convertible Note for the principal amount not so
converted, dated as of the last preceding date to which interest shall have been
paid. Subject to the following provisions of this paragraph, such conversion
shall be deemed to have been made as of the date of such surrender of the
Convertible Note and at the Conversion Price in effect at the date of such
surrender; and the person or persons entitled to receive the Common Stock
deliverable upon conversion of the Convertible Note shall be treated for all
purposes as the record holder or holders of such Common Stock on such date. The
Company shall not be required to convert the Convertible Note or any portion
thereof while the stock transfer books of the Company are closed for any
purpose; but the surrender of the Convertible Note for conversion during any
period while such books are so closed shall become effective for conversion
immediately upon reopening of such books, as if the conversion had been made on
the date the Convertible Note were surrendered, and at the Conversion Price in
effect at the date of such surrender.

     No payment or adjustment to the Conversion Price in respect of dividends on
the shares of Common Stock shall be made upon the conversion of any of the
Convertible Notes.

     12.4. ADJUSTMENT OF CONVERSION PRICE.

           (a) In case the Company shall at any time issue or sell any shares of
Common Stock, for a consideration per share less than the Conversion Price in
effect immediately prior to the issuance or sale of such shares, or without
consideration, then, and thereafter successively upon each such issuance or
sale, the Conversion Price in effect immediately prior to such issuance or sale
shall forthwith be reduced to a price determined by dividing (i) an amount equal
to (X) the total number of shares of Common Stock outstanding immediately prior
to such issuance or sale multiplied by the Conversion Price in effect
immediately prior to such issuance or sale, plus (Y) the

                                       44
   52



consideration, if any, received by the Company upon such issuance or sale, by
(ii) the total number of shares of Common Stock outstanding immediately after
such issuance or sale.

     For the purposes of any computation to be made in accordance with the
provisions of this paragraph (a), the following shall be applicable:

               (i) In case of the issuance or sale of shares of Common Stock for
     a consideration part or all of which shall be cash, the amount of the cash
     consideration therefor shall be deemed to be the amount of cash received by
     the Company for such shares (or, if such shares of Common Stock are offered
     by the Company for subscription, the subscription price, or, if shares of
     Common Stock shall be sold to underwriters or dealers for public offering
     without a subscription offering, the public offering price) before
     deducting therefrom any commissions or other expenses paid or incurred by
     the Company for any underwriting of, or otherwise in connection with the
     issuance of such shares;

               (ii) In case of the issuance or sale of shares of Common Stock
     for a consideration part or all of which shall be other than cash
     (otherwise than as a dividend or other distribution on any shares of Common
     Stock of the Company or on conversion, exercise or exchange of other
     securities of the Company or upon acquisition of the assets or securities
     of another company or upon merger or consolidation with another entity),
     the amount of consideration therefor other than cash shall be the value of
     such consideration as of the date of the issuance or sale of the shares of
     Common Stock, irrespective of any accounting treatment, but as determined
     by the Board of Directors of the Company in good faith. The
     reclassification of securities other than Common Stock into Common Stock
     shall be deemed to involve the issuance for a consideration other than cash
     of such Common Stock immediately prior to the close of business on the date
     fixed for the determination of security holders entitled to receive such
     Common Stock;

               (iii) In case of the issuance of shares of Common Stock upon
     conversion or exchange of any obligations or of any securities of the
     Company that shall be convertible into or exchangeable for shares of Common
     Stock or upon the exercise of rights or options to subscribe for or to
     purchase shares of Common Stock (other than upon conversion of the
     Preferred Stock and the Notes), the amount of consideration received by the
     Company for such shares of Common Stock shall be deemed to be the sum of
     (A) the amount of the consideration received by the Company upon the
     original issuance of such obligations, securities, rights or options, as
     the case may be, plus (B) the consideration, if any, other than such
     obligations, securities, rights or options, payable to the Company in
     connection with such conversion, exchange, or exercise. The amount of the
     consideration received by the Company upon the original issuance of the
     obligations, securities, rights or options so converted, exchanged or
     exercised and the amount of the consideration, if any, other than such
     obligations, securities, rights or options, received by the Company upon
     such conversion, exchange or exercise shall be determined in the same
     manner provided in subparagraphs (i) and (ii) above with respect to the
     consideration received by the Company

                                       45
   53



     in case of the issuance of shares of Common Stock; if such obligations,
     shares, rights or options shall have been issued as a dividend upon any
     securities of the Company, the amount of the consideration received by the
     Company upon the original issuance thereof shall be deemed to be zero.

               (iv) Shares of Common Stock issuable by way of dividend or other
     distribution on any securities of the Company shall be deemed to have been
     issued and to be outstanding at the close of business on the record date
     fixed for the determination of security holders entitled to receive such
     dividend or other distribution and shall be deemed to have been issued
     without consideration. Shares of Common Stock issued otherwise than as a
     dividend, shall be deemed to have been issued and to be outstanding at the
     close of business on the date of issue;

               (v) The number of shares of Common Stock at any time outstanding
     shall not include any shares then owned or held by or for the account of
     the Company, but shall include the aggregate number of shares deliverable
     in respect of options, rights and convertible and exchangeable securities
     at all times while such options, rights or securities remain outstanding
     and unexercised, unconverted or unexchanged, as the case may be, and
     thereafter to the extent such options, rights or securities have been
     exercised, converted or exchanged; and

               (vi) No adjustment shall be made to the Conversion Price then in
     effect in case of the issuance of shares of Common Stock upon conversion or
     exchange of any obligations or of any securities of the Company that shall
     be convertible into or exercisable or exchangeable for shares of Common
     Stock or upon the exercise of rights or options to subscribe for or to
     purchase shares of Common Stock for which an adjustment in the Conversion
     Price has previously been made in accordance with paragraph (b) of this
     Section 12.4.

               (vii) In the event that any payment is made to the holders of
     warrants issued pursuant to the Securities Purchase Agreement dated as of
     January 31, 1997 among the Company, Triumph-Connecticut Limited Partnership
     and the other purchasers named therein pursuant to Section 8.3(b) (or
     successor provision) of such Securities Purchase Agreement which does not
     result in a modification pursuant to Section 12.8, the Company shall be
     deemed to have issued without consideration as of the date of the event
     giving rise to such payment a number of shares of Common Stock equal to the
     amount of such payment divided by the Closing Price on the date of such
     event.

          (b) In case the Company shall at any time issue options or rights to
subscribe for shares of Common Stock, or issue any obligations or securities
convertible into or exchangeable for shares of Common Stock, otherwise than as
contemplated by Section 12.4(a)(vi) hereof, for a consideration per share less
than the Conversion Price in effect immediately prior to the issuance of such
options or rights or convertible or exchangeable securities, or without
consideration, the

                                       46
   54



Conversion Price in effect immediately prior to the issuance of such options or
rights or securities shall be reduced to a price determined by making a
computation in accordance with the provisions of clause (a) of this Section
12.4, provided that:

               (i) the aggregate maximum number of shares of Common Stock
     deliverable under such options or rights shall be considered to have been
     delivered at the time such options or rights were issued, and for a
     consideration equal to the minimum purchase price per share of Common Stock
     provided for in such options or rights, plus the consideration (determined
     in the same manner as consideration received on the issue or sale of Common
     Stock), if any, received by the Company for such options or rights;

               (ii) the aggregate maximum number of shares of Common Stock
     deliverable upon conversion of or exchange for any such obligations or
     securities shall be considered to have been delivered at the time of
     issuance of such securities, and for a consideration equal to the
     consideration (determined in the same manner as consideration received on
     the issue or sale of Common Stock) received by the Company for such
     securities, plus the consideration, if any, to be received by the Company
     upon the exchange or conversion thereof; and

               (iii) on the expiration of such options or rights, or an increase
     in the minimum exercise price thereof, or a decrease in the maximum number
     of shares of Common Stock deliverable upon exercise or conversion of such
     options, rights or convertible or exchangeable securities pursuant to the
     terms thereof (and not as a result of exercise or conversion), or the
     termination of such right to convert or exchange, the Conversion Price then
     in effect shall forthwith be readjusted to such Conversion Price as would
     have obtained (A) in the case of the expiration or termination of options
     or rights or the termination of the right to convert or exchange
     convertible or exchangeable securities, had no adjustments been made upon
     the issuance of such options, rights or convertible or exchangeable
     securities, or (B) in the case of an increase in the minimum exercise price
     thereof, or a decrease in the maximum number of shares deliverable
     thereunder, had the adjustments made upon the issuance of such options,
     rights or convertible or exchangeable securities been made upon the basis
     of the delivery of only the number of shares of Common Stock (A) actually
     deliverable upon the exercise of such options or rights or upon conversion
     or exchange of such securities, or (B) deliverable by reason of such
     increase in price or decrease in number of shares.

          (c) Notwithstanding Sections 12.4(a) and (b), no adjustment to the
Conversion Price shall be made in connection with the issuance of:

               (i) the Securities and the securities issued or issuable upon
     conversion or exercise of the Securities, or other currently outstanding
     Derivative Securities; and

                                       47

   55



               (ii) shares of Common Stock or rights, options or warrants to
     acquire Common Stock issued to directors, employees or consultants of the
     Company pursuant to a stock option plan, employee stock purchase plan,
     restricted stock plan or other similar stock plan or agreement (and, in the
     case of rights, options, or warrants, the Common Stock issued or issuable
     upon exercise thereof) and approved by the Board of Directors.

          (d) In case the Company shall at any time subdivide or combine the
outstanding shares of Common Stock, the Conversion Price in effect shall
forthwith be proportionately decreased in the case of the subdivision or
proportionately increased in the case of combination to the nearest one cent.
Any such adjustment shall become effective at the close of business on the date
that such subdivision or combination shall become effective.

     12.5. NOTICE OF CERTAIN CORPORATE ACTION.

   
           In case:
    

               (i) the Company shall declare any dividend (or any other
     distribution) on shares of its Common Stock; or

               (ii) the Company shall authorize the granting to holders of its
     shares of Common Stock generally of rights or warrants entitling them to
     subscribe for or purchase any shares of capital stock of the Company or of
     any other rights or warrants; or

               (iii) of any reclassification of the shares of Common Stock of
     the Company, or of any consolidation or merger to which the Company is a
     party and for which approval of any stockholders of the Company is
     required, or of the sale or transfer of all or substantially all of the
     assets of the Company, or of any compulsory share exchange whereby the
     Common Stock will be converted into cash or other securities or property;
     or

               (iv) of the voluntary or involuntary dissolution, liquidation or
     winding-up of the Company;

then the Company shall cause to be filed with the transfer agent for the
Convertible Notes, and shall cause to be mailed to all holders of Convertible
Notes at their last addresses as they shall appear on the stock transfer books
of the Company, at least fifteen (15) days prior to the applicable record date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, redemption or granting of
rights or warrants, or, if a record is not to be taken, the date as of which the
holders of shares of Common Stock of record to be entitled to such dividend,
distribution, redemption, rights or warrants are to be determined, or (y) the
date on which such reclassification, consolidation, merger, sale, transfer,
share exchange, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of shares of
Common Stock of record shall be

                                       48
   56



entitled to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, share exchange, dissolution, liquidation or winding-up. Such notice
shall also state whether such transaction will result in any adjustment in the
Conversion Price applicable to the Convertible Notes and, if so, shall state
what the adjusted Conversion Price will be and when it will become effective.
Neither the failure to give the notice required by this Section, nor any defect
therein, to any particular holder of Convertible Notes shall affect the
sufficiency of the notice or the legality or validity of any such dividend,
distribution, redemption, right, warrant, reclassification, consolidation,
merger, sale, transfer, share exchange, liquidation, dissolution or winding-up,
or the vote on any action authorizing such with respect to the other holders.

     12.6. TAXES ON CONVERSIONS.

     The Company will pay any and all stamp or similar taxes that may be payable
in respect of the issuance or delivery of shares of Common Stock on conversion
of the Convertible Notes pursuant hereto. The Company shall not, however, be
required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of shares of Common Stock in a name other than that
of the holder of the Convertible Notes to be converted, and no such issuance or
delivery shall be made unless and until the person requesting such issuance has
paid to the Company the amount of any such tax, or has established to the
satisfaction of the Company that such tax has been paid.

     12.7. FRACTIONAL SHARES.

     No fractional shares or scrip representing fractional shares shall be
issued upon the conversion of the Convertible Notes. If any such conversion
would otherwise require the issuance of a fractional share an amount equal to
such fraction multiplied by the Current Market Price per share of Common Stock
on the day of conversion shall be paid to the holder in cash by the Company. All
conversions by the same holder on any particular day shall be aggregated.

     12.8. PROVISIONS IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS.

     In the case of any reorganization or reclassification of the outstanding
shares of Common Stock (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination) or in the case of any consolidation of the Company into, or
merger of the Company with another entity in which the Company is not the
surviving entity (or it is the surviving entity, but its shares of Common Stock
become shares of another entity), or in the case of any sale, lease or
conveyance of all, or substantially all, of the property, assets, business and
goodwill of the Company as an entirety, each holder of Convertible Notes shall
thereafter have the right to convert such Convertible Notes into the kind and
amount of securities, cash and other property receivable upon such
reorganization, reclassification, consolidation, merger or disposition by a
holder of the number of shares of Common Stock which the holder of Convertible
Notes would have received had it converted its

                                       49
   57



shares of Series G Preferred Stock immediately prior to such reorganization,
reclassification, consolidation, merger or disposition, at a price equal to the
aggregate Conversion Price then in effect; provided, however, that the kind and
amount of such securities, cash and other property shall be determined as if any
payment made to the holders of warrants issued pursuant to the Securities
Purchase Agreement dated as of January 31, 1997 among the Company,
Triumph-Connecticut Limited Partnership and the other purchasers named therein
upon such reorganization, reclassification, consolidation, merger or disposition
in excess of the amount such holders would otherwise have been entitled to
receive under the terms of such warrants without regard to Section 8.3(b) (or
successor provision) of such Securities Purchase Agreement had not been made.
The foregoing provisions of this Section shall similarly apply to successive
reorganizations, reclassifications, consolidations, mergers and dispositions.

     12.9. COVENANT TO RESERVE SHARES.

     The Company covenants that it will at all times reserve and keep available,
free from preemptive rights, out of its authorized shares of Common Stock,
solely for the purpose of issuance upon conversion of the Convertible Notes as
herein provided, such number of shares of Common Stock as shall then be issuable
upon the conversion of all outstanding Convertible Notes. The Company covenants
that all shares of Common Stock which shall be so issuable shall be, when
issued, duly and validly issued and fully paid and non-assessable. For purposes
of this Section 12.9, the number of shares of Common Stock which shall be
deliverable upon the conversion of all outstanding Convertible Notes shall be
computed as if at the time of computation all outstanding Convertible Notes were
held by a single holder.

     12.10. RULE 13e-3 TRANSACTIONS .

     In case the Company or any Affiliate of the Company shall propose to engage
in a "Rule 13e-3 Transaction" as defined in Rule 13e-3 promulgated under the
Exchange Act the Company shall, no later than the date on which any information
with respect to such Rule 13e-3 Transaction is first required to be given to the
Securities and Exchange Commission or any other person pursuant to such Rule
13e-3, cause to be mailed to all holders of Convertible Notes at their last
addresses as they shall appear on the books of the Company, a copy of all
information required to be given to the Securities Exchange Commission or such
other person pursuant to such Rule 13e-3. The information required to be given
under this paragraph shall be in addition to and not in lieu of any other
information required to be given by the Company pursuant to this Article.

     12.11. AUTOMATIC CONVERSION. The Convertible Notes shall automatically
convert into shares of Common Stock at the applicable Conversion Price, in
accordance with this Article XII, in the event that the average daily Closing
Price of the Common Stock for thirty (30) consecutive trading days beginning any
time after three years from the date of issuance of the Convertible Notes is
greater than $12.00 per share, subject to adjustment for stock splits, stock
dividends, combinations and other similar recapitalizations, so long as the
average daily trading volume

                                       50
   58



during the preceding thirty (30) days is at least 35,000 shares. The date upon
which the foregoing condition is satisfied is hereinafter referred to as the
"Mandatory Conversion Date."

     All holders or record of Convertible Notes will be given written notice of
the Mandatory Conversion Date and the place designated for mandatory conversion
of all such Convertible Notes pursuant to this Section 12.11. Such notice need
not be given in advance of the occurrence of the Mandatory Conversion Date. Such
notice shall be sent by first class or registered mail, postage prepaid, to each
record holder of Convertible Notes at such holder's address last shown on the
records of the transfer agent for the Convertible Notes (or the records of the
Company, if it serves as its own transfer agent). Upon receipt of such notice,
each holder of Convertible Notes shall surrender his or its Convertible Notes to
the Company at the place designated in such notice, and shall thereafter receive
certificates for the number of shares of Common Stock to which such holder is
entitled pursuant to this Section 12.11. On the Mandatory Conversion Date, all
rights with respect to the Convertible Notes so converted, including the rights,
if any, to receive notices and vote, will terminate, except only the rights of
the holders thereof, upon surrender of their Convertible Notes therefor, to
receive certificates for the number of shares of Common Stock into which such
Convertible Notes have been converted. If so required by the Company,
Convertible Notes surrendered for conversion shall be endorsed or accompanied by
written instrument or instruments or transfer, in form satisfactory to the
Company, duly executed by the registered holder or by his or its attorney duly
authorized in writing. As soon as practicable after the Mandatory Conversion
Date and the surrender of the Convertible Notes, the Company shall cause to be
issued and delivered to such holder a certificate or certificates for the number
of full shares of Common Stock into which the Convertible Notes have been
converted and cash as provided herein with respect to any fraction of a share of
Common Stock otherwise issuable upon such conversion.

     All Convertible Notes which are required to be surrendered for conversion
in accordance with the provisions hereof shall, from and after the Mandatory
Conversion Date, be deemed to have been retired and cancelled and the
Convertible Notes represented thereby converted into Common Stock and cash as
provided herein for all purposes, notwithstanding the failure of the holder or
holders thereof to surrender such Convertible Notes on or prior to such date.


                                  ARTICLE XIII

                                EVENTS OF DEFAULT

     13.1. EVENTS OF DEFAULT.    An "Event of Default" occurs if:

           (a) the Company shall default in the payment of (i) any part of the
principal of any Note, when the same shall become due and payable, whether at
maturity or at a date fixed for prepayment, acceleration or otherwise; or (ii)
the interest on any Note, when the same shall become due and payable and shall
not pay such interest within five (5) days thereafter; or

                                       51

   59



           (b) the Company shall default in the performance of any of the
covenants contained in Section 7.6 or Article VIII of this Agreement; or

           (c) the Company shall default in the performance of any of the
covenants contained in this Agreement (other than the covenants contained in
Section 7.6 or Article VIII hereof) and such default shall have continued for
the period and after the notice specified in the penultimate paragraph of this
Section 13.1 (the "Default Notice") without cure (the Company to give forthwith
to all other holders of the Notes at the time outstanding written notice of the
receipt of such Default Notice, specifying the default referred to therein); or

           (d) any representation or warranty made in this Agreement shall prove
to have been incorrect in any material respect when made; or

           (e) any default shall occur under any indenture, mortgage, agreement,
instrument or commitment evidencing or under which there is at the time
outstanding any indebtedness of the Company or any Subsidiary, in excess of
$200,000, or which results in such indebtedness, in an aggregate amount (with
other defaulted indebtedness) in excess of $200,000 becoming due and payable
prior to its due date and if such indenture, mortgage, agreement, instrument or
commitment so requires, the holder or holders thereof (or a trustee on their
behalf) shall have declared such indebtedness due and payable; or

           (f) the Company or any of its Subsidiaries shall default in the
observance or performance of any term or provision of a material agreement to
which it is a party or by which it is bound, which default is reasonably
expected to have a Material Adverse Effect on the Company, and such default is
not waived or cured within the applicable grace period; or

           (g) an outstanding unsatisfied final judgment which, either alone or
together with other outstanding unsatisfied final judgments, against the Company
and its Subsidiaries exceeds an aggregate of $200,000 (to the extent not covered
by insurance) shall be rendered against the Company or any Subsidiary and such
judgment shall have continued undischarged or unstayed for thirty (30) days
after entry thereof; or

           (h) the Company or any Subsidiary shall make a general assignment for
the benefit of creditors, or shall admit in writing its inability to pay its
debts; or the Company or any Subsidiary shall suffer a receiver or trustee for
it or substantially all of its assets to be appointed; or the Company or any
Subsidiary shall suffer proceedings under any law relating to bankruptcy,
insolvency or the reorganization or relief of debtors to be instituted by or
against it, and, if contested by it, not to be dismissed or stayed within ninety
(90) days; or the Company or any Subsidiary shall suffer any writ of attachment
or execution or any similar process to be issued or levied against it or any
significant part of its property which is not released, stayed, bonded or
vacated within ninety (90) days after its issue or levy; or the Company or any
Subsidiary takes corporate action in furtherance of any of the aforesaid
purposes or conditions.

     A default under paragraph (c) of this Section 13.1 is not a default unless
the holders of at least eighty percent (80%) of the aggregate principal amount
then outstanding under the Notes notify the Company of the default and the
Company does not cure the default within twenty (20) days after receipt of such
notice. The notice must specify the default and demand that it be remedied.

     A "Default" means any of the events specified in this Section 13.1,
regardless of whether there shall have occurred any passage of time or giving of
notice or both that would be necessary in order to constitute such event an
Event of Default.

     13.2. REMEDIES.

           (a) Upon the occurrence of an Event of Default (other than an Event
of Default specified in paragraph (h) of Section 13.1), holders of at least
eighty percent (80%) in aggregate principal amount of the Notes at the time
outstanding may at any time (unless all defaults shall theretofore have been
remedied) at their option, by written notice or notices to the Company declare
all the Notes to be due and payable, whereupon the same shall forthwith mature
and become due and payable, together with interest accrued thereon, without
presentment, demand, protest or notice, all of which are hereby waived;. If an
Event of Default specified in paragraph (h) of Section 13.2 occurs, all
principal of and interest on the Notes shall automatically become and be
immediately due and payable without any declaration or other act.

           (b) Notwithstanding anything contained in Section 13.2(a), in the
event that at any time after the principal of the Notes shall so become due and
payable and prior to the date of maturity stated in the Notes all arrears of
principal of and interest on the Notes (with interest at the rate specified in
the Notes on any overdue principal and, to the extent legally enforceable, on
any interest overdue) shall be paid by or for the account of the Company, then
holders of at least eighty percent (80%) in aggregate principal amount of the
Notes then outstanding, by written notice or notices to the Company, may (but
shall not be obligated to) waive such Event of Default and its consequences and
rescind or annul such declaration, but no such waiver shall extend to or affect
any subsequent Event of Default or impair any right resulting therefrom. If any
holders of Notes shall give any notice or take any other action with respect to
a claimed default, the Company, forthwith upon receipt of such notice or
obtaining knowledge of such other action will give written notice thereof to all
other holders of the Notes then outstanding, describing such notice or other
action and the nature of the claimed default.

     13.3. ENFORCEMENT. In case any one or more Events of Default shall occur
and be continuing, the holder of a Note then outstanding may proceed to protect
and enforce the rights of such holder by an action at law, suit in equity or
other appropriate proceeding, whether for the specific performance of any
agreement contained herein or in such Note or for an injunction against a
violation of any of the terms hereof or thereof, or in aid of the exercise of
any power granted hereby or thereby or by law. Each holder agrees that it will
give written notice to the other holders

                                       53
   61



prior to instituting any such action. In case of a default in the payment of any
principal of or interest on any Note, the Company will pay to the holder thereof
such further amount as shall be sufficient to cover the cost and expense of
collection, including, without limitation, reasonable attorneys' fees, expenses
and disbursements. No course of dealing and no delay on the part of any holder
of any Note in exercising any rights shall operate as a waiver thereof or
otherwise prejudice such holder's rights. No right conferred hereby or by any
Note upon any holder thereof shall be exclusive of any other right referred to
herein or therein or now available at law, in equity, by statute or otherwise.


                                   ARTICLE XIV

                              AMENDMENT AND WAIVER

     This Agreement may not be amended or modified (or any provision hereof
waived), except that the Company and the Purchasers (and permitted assignees of
the Purchasers) holding at least eighty percent (80%) of the Preferred Stock and
Preferred Conversion Shares issuable upon conversion of the Preferred Stock, at
least eighty percent (80%) in principal amount of the Convertible Notes, if
issued, and the Note Conversion Shares issuable upon conversion of the
Convertible Notes, at least eighty percent (80%) in principal amount of the
Subordinated Notes and at least eighty percent (80%) of the Warrants and Warrant
Shares issued upon exercise of the Warrants may by written instrument amend,
modify or waive any term or condition of this Agreement relating to the rights
or obligations of such holders; provided that (i) any provision of Article VII,
VIII and XI may be amended, modified or waived with the written consent of the
Company and the holders of at least eighty percent (80%) of the sum of (a)
aggregate outstanding principal amount of the Notes outstanding and (b) the
aggregate liquidation preference of the shares of Preferred Stock outstanding;
(ii) any provision of Article IX and XIII may be amended, modified or waived
solely with the written consent of the Company and the holders of at least
eighty percent (80%) of the aggregate principal amount of the Notes outstanding;
(iii) any provision of Article X may be amended, modified or waived with the
written consent of the Company and the holders of at least eighty percent (80%)
of the Registrable Securities (assuming conversion of all Preferred Stock or
Convertible Notes); (iv) any provision of Article XII may be amended, modified
or waived with the written consent of the Company and the holders of at least
eighty percent (80%) of the aggregate liquidation preference of the shares of
Preferred Stock outstanding or at least eighty percent (80%) of the aggregate
principal amount of the Convertible Notes outstanding. However, without the
consent of each holder of a Note, the provisions of this Agreement and the Notes
may not be amended or waived to:

           (1) reduce the amount of holders who must consent to an amendment,
     supplement or waiver of this Agreement and the Notes;

           (2) reduce the rate of or change the time for payment of interest on
     any Note;

                                       54

   62



           (3) reduce the principal of or change the fixed maturity of any Note
     or alter the redemption provisions with respect thereto;

           (4) waive a default in the payment of the principal of or interest on
     any Note; or

           (5) make any Note payable in money other than that stated in such
     Note.

     After an amendment, supplement or waiver of a provision of this Agreement
and the Notes becomes effective, the Company shall mail to the holders affected
thereby a notice briefly describing the amendment, supplement or waiver.

     In no event shall the obligation of any holder of Securities, Preferred
Conversion Shares, Notes, Conversion Shares or Warrant Shares hereunder be
increased, except upon the written consent of each such holder. In addition,
notwithstanding the other provisions of this Article XIV, no amendment,
modification or waiver of any provision of this Agreement that adversely affects
the rights of any holder of Securities, Preferred Conversion Shares, Notes,
Conversion Shares or Warrant Shares in a manner different from the rights of the
other holders thereof shall be effective against such holder unless approved in
writing by such holder.

     The Company and each holder of Securities (including any Preferred
Conversion Shares, Note Conversion Shares and Warrant Shares) shall be bound by
any amendment or waiver effected in accordance with the provisions of this
Article XIV, whether or not such securities shall have been marked to indicate
such modification, but any securities issued thereafter shall bear a notation as
to any such modification. Promptly after obtaining the written consent of the
holders herein provided, the Company shall transmit a copy of such modification
to all holders of Securities.


                                   ARTICLE XV

                         LOST OR MUTILATED CERTIFICATES

     Upon receipt of evidence satisfactory to the Company of the loss, theft,
destruction or mutilation of any certificate for Securities and, in the case of
any such loss, theft, or destruction, upon delivery of a bond of indemnity
satisfactory to the Company (provided that if the holder is a financial
institution, its own agreement will be satisfactory), or in the case of any such
mutilation, upon surrender and cancellation of such certificate, the Company
will issue a new certificate of like tenor as if the lost, stolen, destroyed or
mutilated certificate were then surrendered for exchange in lieu of such lost,
stolen, destroyed or mutilated certificate.

     16.1. TRANSFER OF SECURITIES.

           (a) No sale or other disposition shall be made with respect to any
Securities; any shares of Common Stock issuable upon conversion or exercise of
any Securities or any other securities issued in respect of the Securities, upon
any stock split, stock dividend, recapitalization, merger, consolidation or
similar event unless (i) the holder shall have supplied to the Company an
opinion of counsel for the holder reasonably acceptable to the Company to the
effect that no registration under the Securities Act or other applicable law is
required with respect to such sale or other disposition, or (ii) an appropriate
registration statement with respect to such sale or other disposition shall have
been filed by the Company and declared effective by the SEC. The Company may
endorse on all certificates for such Securities the legend in Section 10.1
hereof restricting their transfer expect upon compliance with this Article XVI,
and provided, further, that if an opinion of counsel satisfactory to the Company
concludes that the legend is no longer necessary, the Company will deliver upon
transfer such Securities without such legends. Each transferee of such
securities shall agree in writing to be bound by the terms of this Agreement.

           (b) Any transferee (other than a Purchaser who is a signatory to this
Agreement) to whom rights hereunder are transferred shall, as a condition to
such transfer, deliver to the Company a written instrument by which such
transferee agrees to be bound by the obligations imposed upon Purchasers under
this Agreement, to the same extent as if such transferee were a party hereto.

           (c) A transferee to whom rights are transferred pursuant to this
Section 16.1 may not again transfer such rights to any other person or entity,
other than as provided in this Section 16.1.

           (d) Any transferee to whom a transfer is made in accordance with this
Section 16.1 shall be deemed a "Purchaser" for purposes of this Agreement,
except as provided in Section 17.3.

     16.2. LIMITATION ON NUMBER OF HOLDERS. No sale or other disposition shall
be made with respect to any Securities if, as a result thereof, there would be
more than twenty one (21) holders of Securities; provided that this limitation
shall cease to be applicable to a Purchaser and its transferees and successive
transferees if such Purchaser distributes Securities in kind to its partners or
members; provided, however, that the foregoing limitation shall not be
applicable to any Securities or securities issued upon conversion or exercise of
the Securities which have been sold in a registered offering under the
Securities Act or pursuant to Section 4(1) of the Securities Act or Rule 144
under the Securities Act; provided, further, however, that, prior to
registration under the Securities Act, the Securities initially issued to Furman

not assign its rights hereunder, except to an affiliated corporation as a result
of a merger or consolidation in which the Company is not the surviving
corporation, and, provided further, that if a Purchaser should assign its rights
and benefits under this Agreement to a person that is not an Affiliate of such
Purchaser, such assignee shall not be deemed a "Purchaser" for purposes of
Section 7.5 of this Agreement.

conditions of this Agreement must be, made in writing and shall be effective

with the exercise of rights under this Agreement, unless the Company has made
such information available to the public generally or such Purchaser is required
to disclose such information by a governmental body or pursuant to legal
proceedings. For purposes herein, "confidential information" shall mean and

brought against any of the parties hereto or any other person entitled to the
benefits of Section 10.7 of this Agreement, provided that such party or person
has the right to seek indemnification under such section.

     17.12. TITLES AND SUBTITLES. The titles of the articles, sections and
subsections of this Agreement are for convenience of reference only and are not
to be considered in construing this Agreement.

     17.13. COUNTERPARTS. This Agreement may be executed in counterparts, each
of which shall be an original, but all of which together shall constitute one
instrument.
