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

      THIS CONVERTIBLE SUBORDINATED DEBENTURE PURCHASE AGREEMENT ("Agreement")
is made as of the 22nd day of December, 1994, by and between MEMRY CORPORATION,
a Delaware corporation (the "Company"), and CONNECTICUT INNOVATIONS,

Certain capitalized terms used herein and not defined where used are defined in
Section 8 hereof.

      THE PARTIES HEREBY AGREE AS FOLLOWS:

purchase 305,283 shares of Common Stock at an initial price of $2.75 per share,

as a result of arm's length bargaining, agree that (i) the Investor has not
rendered or agreed to render any services to the Company in connection with this
Agreement or the issuance of the Debenture, Class I Warrants and Class II
Warrants; and (ii) the assumed price at which the Debenture would be issued if

the Company rely thereon, as follows:

                  (a) The Investor will not sell, assign, pledge, transfer, or
otherwise dispose of, whether directly or indirectly, all or any portion of the
Purchased Securities, or any Common Stock obtained upon the exercise or
conversion of the Purchased Securities or as a stock dividend on the Common
Stock so obtained (such Common Stock being hereinafter collectively referred to
as the "Underlying Securities"; the Purchased Securities and the Underlying
Securities are hereinafter collectively referred to as the "Securities")), to
any person or entity without complying with applicable securities laws;

                  (b) The Investor is acquiring the Purchased Securities and the
Underlying Securities for the Investor's own account, for investment purposes
only and not with a view to any distribution of such Securities;

                  (c) The Investor acknowledges and agrees that the Company has
informed the Investor that the Securities are not registered under any
securities laws, and, therefore, that (absent registration under or exemption
from applicable securities laws) the Securities are subject to substantial
restrictions on transfer;

                                      - 3 -

                  (d) The Investor has investigated the purchase of the
Securities to the extent the Investor deems necessary or desirable, and the
Company has provided the Investor with any assistance in connection therewith
which Investor has requested. The Investor has such knowledge and experience in
financial and business matters that the Investor is capable of evaluating the
merits and risks of the acquisition of the Securities and of making an informed
investment decision with respect thereto and the Investor has the ability to
bear the economic risk of an investment in the Company and to withstand a
complete loss of its investment. The Investor is financially able to hold the
Securities for an indefinite period of time;

                  (e) The Investor has been furnished by the Company with all
information the Investor has reasonably requested in order to form an informed
investment decision concerning the purchase of the Securities. The Investor has
been afforded an opportunity to ask questions of, and receive answers from
representatives of the Company concerning the terms and conditions of the
Investor's purchase of the Securities and has been afforded the opportunity to
obtain any additional information (to the extent the Company had such
information or could acquire it without unreasonable effort or expense)
necessary to verify the accuracy of information otherwise furnished by the
Company;

                  (f) The Investor understands that no United States federal or
state agency or any agency of any other government has passed upon or made any
recommendation or endorsement of any investment in the Company;

                  (g) The Investor has not been organized for the purpose of
purchasing the Securities;

                  (h) The Investor is a "financial institution" or
"institutional buyer" as such terms are defined in Section 36- 490(b)(8) of the
General Statutes of Connecticut;

                  (i) The Investor understands that the certificates evidencing
the Purchased Securities and any Underlying Securities will bear a legend
stating in substance:

                  "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR
SALE, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF A
REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT
OR AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE
<PAGE>
 
                                     - 4 -


COMPANY THAT SUCH SALE, OFFER FOR SALE, PLEDGE, HYPOTHECATION OR OTHER
DISPOSITION DOES NOT VIOLATE THE PROVISIONS OF SUCH ACT OR UNLESS SOLD PURSUANT
TO RULE 144 OF SUCH ACT."

provided, however, that the Company agrees to cause such legend to be removed
from any certificates representing any Securities after such Securities have
been transferred pursuant to a registered public offering, an effective
exemption under Section 4(1) of that Act, or Rule 144 promulgated thereunder;
and

                  (j) The Investor agrees and acknowledges that, as of the date
hereof: (i) the Company has not reserved shares of Common Stock for issuance
upon the exercise of the Class I Warrants, the Class II Warrants or the 90,000
additional shares of Common Stock that the Class III Warrants (as defined in
Section 7.7 hereof) are being amended to grant to the Investor, or upon the
conversion of the Debenture, except as described in Section 3.7 below; (ii) that
the Company does not currently have authorized and unreserved a sufficient
number of shares of Common Stock to allow for the full conversion and exercise
of the Purchased Securities; and (iii) that pursuant to the terms of the
Purchased Securities and this Agreement, while the Company is obligated to use
its best efforts to cause such a sufficient number of shares to be authorized
and reserved for issuance upon the conversion and exercise of the Purchased
Securities as soon as practicable, it is not required to accomplish the same
prior to September 1, 1995.

      3.  Representations and Warranties of the Company. The Company hereby
          ---------------------------------------------
represents and warrants to the Investor as follows:

      3.1 Registration and Other Rights. Except as set forth on Schedule A, and
          -----------------------------
with respect to the registration rights granted herein, there are no "side
agreements" or other agreements or understandings with any person regarding
registration of securities of the Company under the Securities Act of 1933, as
amended. Between June 30, 1994 and the date hereof, no securities of the Company
have been sold which provide any registration or other rights more favorable
than those set forth herein. Between the date hereof and July 1, 1995, the
Company agrees that it will not provide any registration or other rights more
favorable than those set forth herein unless the Investor is also concurrently
offered comparable rights or unless such rights differ only as to price and
trigger adjustments to the conversion price for the Debenture and the exercise
price for the Class I Warrants and the Class II Warrants. The Company shall
provide the Investor with copies of all such sale agreements and related
documents.

                                     - 5 -


      3.2 Amount of Financing. The Company is closing, concurrently with the
          -------------------
Investment, or has already closed, on a minimum of $4,000,000, in addition to
the amount provided by the Investor, of payments for the Company's equity or
convertible indebtedness since January 1, 1993. Schedule B hereto contains a
list of such payments.

      3.3 No Adverse Change. Since the date of the Placement Memorandum (as
          -----------------
hereinafter defined) there have not been any changes in the business, prospects
or affairs of the Company which, in the aggregate, have been, or are expected to
be, materially adverse, which have not been disclosed in the Company's Annual
Report on Form 10-KSB for the fiscal year ended June 30, 1994, or the Company's
Quarterly Report on Form 10-QSB for the first quarter of the Company's current
fiscal year.

      3.4 Authorization. All action on the part of the Company, its directors
          -------------
and shareholders necessary for the authorization, execution, delivery and
performance by the Company of this Agreement and the consummation of the
transactions contemplated herein, and for the authorization, execution and
delivery of the Purchased Securities, have been taken (except that the Company
has not reserved for issuance shares of Common Stock to be issued (x) upon the
exercise of the Class I Warrants, the Class II Warrants or the 90,000 additional
shares of Common Stock that the Class III Warrants are being amended and
restated to grant to the Investor, or (y) upon the conversion of the Debenture
at a conversion price of less than $1.50 per share (although the Company has
duly reserved 508,805 shares of its Common Stock for issuance upon the full
conversion of the Debenture at its original conversion price of $1.50 per share)
nor does the Company currently have authorized and unreserved a sufficient
number of shares of Common Stock to allow for the conversion and exercise of the
Purchased Securities not already reserved for as provided above). This
Agreement, including the exhibits hereto, is a valid and binding obligation of
the Company, enforceable in accordance with its terms against the Company.

      3.5 Disclosure. Neither this Agreement nor any other written statement
          ----------
furnished to the Investor nor its counsel in connection with the investment made
hereby contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained therein or
herein not misleading in the light of the circumstances under which they were
made.

      3.6 Confidentiality, Non-Competition, Proprietary Information and
Employment Agreements. Each of the key employees and consultants of the Company
and of each subsidiary listed on Schedule C has entered into a confidentiality
agreement, a non-competition agreement, a proprietary information and invention
agreement and/or an employment agreement, true and accurate copies of which have
been provided to the Investor.

      3.7     Capitalization.

              (a) Upon the consummation of the Closing, the Company's authorized
capital stock will consist of (i) 10,000,000 shares of Common Stock, of $0.01
par value each, of which 5,370,708 shares (subject to downward adjustment due to
the elimination of fractional shares in conjunction with the Company's
one-for-ten reverse stock split effected on or about August 8, 1994 (the
"Reverse Stock Split")) will be issued and outstanding (1,086,761 shares have
been reserved for issuance upon the conversion of the Company's issued and
outstanding preferred stock, 2,291,000 reserved for issuance upon the conversion
of the Company's issued and outstanding warrants, 600,000 shares have been
reserved for issuance upon the exercise of options under the Company's Stock
Option Plan (under which plan 205,850 options have currently been granted) and
508,805 shares will be reserved for issuance to the Investor upon conversion of
the Debenture) and (ii) 100,000 shares of preferred stock, par value $100.00 per
share, of which 124 shares of Series A Preferred Stock and 250 shares of Series
B Preferred Stock are currently outstanding. Except as set forth on Schedule D,
the Company has not approved sales of or agreed to issue any additional shares
of the Company's Common Stock.

              (b) Upon consummation of the Closing, all issued and outstanding
shares of capital stock of the Company will have been duly authorized and
validly issued, will be fully paid and nonassessable and will have been offered,
issued, sold and delivered by the Company in compliance with applicable federal
and state securities laws. There are no outstanding preemptive or other
preferential rights, conversion rights or other rights, options, warrants or
agreements granted or issued by or binding upon the Company for the purchase or
acquisition of any shares of its capital stock, except with respect to options,
warrants and preferred stock conversion rights for which Common Stock has been
reserved as set forth above, or as set forth on Schedule E. To the Company's
knowledge, no holder of Common Stock has granted any option or other right to
purchase from such shareholder any interest in any share of Common Stock. The
Company holds no shares of its capital stock in its treasury.

                  (c) The Company shall use its best efforts to (i) convene a
meeting of the Company's shareholders as promptly as practicable but in no event
later than September 1, 1995, for the purpose of amending the Company's
Certificate of Incorporation to increase the number of authorized shares of the
Company's Common Stock to a number sufficient to allow for the full exercise and
conversion of the Purchased Securities, and (ii) at such meeting, cause such
proposed amendment (the "Capitalization Amendment") to be adopted. Promptly upon
the adoption of the Capitalization Amendment, the Company shall (i) file with
the Delaware Secretary of State a Certificate of Amendment to Certificate of
Incorporation giving effect to the Capitalization Amendment and (ii) immediately
upon the effectiveness of such filing, reserve a sufficient number of shares of
Common Stock to allow for the full exercise and conversion of the Purchased
Securities.

      4. Registration. The Company covenants and agrees as follows:

              4.1 Definitions.      For purposes of this Section 4:

                  (a) The terms "register", "registered", and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with the Securities Act of 1933, as
amended (the "Act"), and the declaration or ordering of effectiveness of such
registration statement or document;

                  (b) The term "Registrable Securities" means any Underlying
Securities owned or acquirable by the Investor, and any shares of Common Stock
acquired or acquirable upon the exercise of the Class III Warrants (as described

              4.2 Registration of Investor's Resale of the
Registrable Securities.

                  (a) The Company shall (i) promptly convert its registration
statement currently filed under the Act to a registration statement covering,
inter. alia, the resale by the Investor of the Registrable Securities acquired
by it pursuant to this Agreement (the "Registration Statement"), (ii) cause such
Registration Statement to become effective no later than February 28, 1995,
(iii) subject to the provisions of this Section 4, maintain the effectiveness of
the Registration Statement (or, to the extent required, one or more additional
registration statements) for a period of three years from the effective date
thereof, and (iv) use its best efforts to allow the Investor to continually sell
Registrable Securities pursuant to such registration free from any stop orders
or suspensions by the Company or advice of Company's counsel or Investor's
counsel to cease trading. The Company shall furnish to the Investor copies of
all documents filed and correspondence with the SEC relating to the Registration
Statement, and such other information as the Investor shall reasonably request.

                  (b) The Company shall effect the Registration Statement
pursuant to the following conditions:

                        (i) If, at some time in the future, the Holders intend
to distribute the Registrable Securities covered by the registration by means of
an underwriting, they shall so advise the Company. All Holders proposing to
distribute their securities through such underwriting ("Participating Holders")
shall (together with the Company as provided in subsection 4.3(e)) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by a majority in interest of the Participating
Holders. Notwithstanding any other provision of this Section 4.2, if the
underwriter advises the Participating Holders in writing that marketing factors
require a limitation of the number of shares to be underwritten, then the number
of shares of Registrable Securities that may be included in the underwriting
shall be allocated among all Participating Holders thereof in proportion (as
nearly as practicable) to the amount of Registrable Securities of the Company
owned by each Participating Holder.

                        (ii) Notwithstanding the foregoing, if the Company shall
furnish to Holders a certificate signed by the President of the Company stating
that the Company is engaged in an activity which, in the good faith judgment of
the Board of 
<PAGE>
 
                                     - 9 -


Directors of the Company, would be adversely affected by the requested
underwritten registration to the material detriment of the Company, then the
Company shall have the right to defer such underwriting for a period of not more
than four months, provided that such right may not be exercised more than once.

                  (c) In the event that on the third anniversary of the
effective date of the Registration Statement the Investor shall be deemed to be
an affiliate for purposes of Rule 144 under the Act, the Investor shall have the
right to make a written request to the Company for registration under the Act of
the resale of all or part of the Registrable Securities ("Demand Registration")
which Demand Registration the Company shall be obligated to effect pursuant to
and subject to the terms and conditions of this Section 4.

              4.3 Obligations of the Company. With respect to the Registration
Statement, the Company shall, as expeditiously as reasonably possible:

                  (a) Prepare and file with the SEC a registration statement
with respect to the Registrable Securities, and use its best efforts to cause
such registration statement to become effective;

                  (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Act with respect to the disposition of the securities covered
by such registration statement;

                  (c) Furnish to the Investor or, as applicable, the Holders
such numbers of copies of a prospectus, including a preliminary prospectus, in
conformity with the requirements of the Act, and such other documents as the
Investor or, as applicable, the Holders may reasonably request;

                  (d) Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Investor or, as applicable, the Holders to effect such registration statement
or, as applicable, to enable the Holders to consummate the disposition in such
jurisdictions of such securities, provided that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do
<PAGE>
 
                                     - 10 -


business or to file a general consent to service of process in any such states
or jurisdictions;

                  (e) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering (each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement);

                  (f) Notify the Investor or, as applicable, each Holder of
Registrable Securities covered by such registration statement and each
underwriter thereof, if any, of the effectiveness of such registration statement
and, at any time when a prospectus relating thereto is required to be delivered
under the Act, of the happening of any event as a result of which the prospectus
included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements made therein not misleading
in the light of the circumstances then existing, and at the request of the
Investor or, as applicable, any such Holder or underwriter promptly prepare and
furnish to the Investor or, as applicable, such Holder or underwriter, if any, a
reasonable number of copies of a prospectus supplemented or amended so that such
prospectus shall not include an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing; and

                  (g) Furnish, at the request of (i) the Investor, on the date
on which the Registration Statement becomes effective and on such later dates as
requested, or (ii) as applicable, any Holder, on the date that such Holder's
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to Section 4.2(b) hereof, if such securities are
being sold through underwriters, (A) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to the underwriters in an underwritten public
offering, addressed to the Investor or, as applicable, underwriters, if any, and
to the Holders and (B) a letter, dated such date, from the independent public
accountants of the Company, in form and substance as is customarily given by
independent public accountants to underwriters in an underwritten public
offering, addressed to the Investor or, as applicable, the underwriters, if any,
and to the Holders; provided, however, that the Company will only bear the cost
of 
<PAGE>
 
                                     - 11 -


obtaining the comfort described in (A) and (B) above on the first two
occasions thereof, and notwithstanding anything to the contrary contained
elsewhere herein the Investor will be required to bear the costs of obtaining
such comfort on all subsequent occasions.

              4.4 Obligations of Selling Holders.

                  (a) It shall be a condition precedent to the obligations of
the Company to take any action pursuant to this Section 4 with respect to the
Registrable Securities of any selling Holder that such Holder shall furnish to
the Company in writing such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

                  (b) The Holders of Registrable Securities included in a
registration statement will not (until further notice) effect sales thereof
after receipt of telegraphic or written notice from the Company to suspend sales
to permit the Company to correct or update a registration statement or
prospectus.

              4.5 Expenses of Registration. All expenses other than underwriting
discounts and commissions incurred in connection with registrations, filings, or
qualifications pursuant to Section 4.2, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursement of counsel for the Company, transportation expenses, mailing
expenses, and the fees and disbursements of counsel for the selling Holders
shall be borne and paid by the Company.

              4.6 Underwriting Requirements. In connection with any offering
involving an underwriting of shares being issued by the Company, the Company
shall not be required to include any of the Holders' securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it, and then only in such
quantity as will not, in the opinion of the underwriters, jeopardize the success
of the offering by the Company. If the total amount of securities, including
Registrable Securities, requested by shareholders to be included in such
offering exceeds the amount of securities to be sold other than by the Company
that the underwriters reasonably believe compatible with the success of the
offering, then the Company shall be required to include in the offering only
that number of such securities, including Registrable Securities, which the
underwriters believe will not jeopardize the success of the offering (the
securities so included to be 
<PAGE>
 
                                     - 12 -


apportioned pro rata among the selling Holders according to the total amount of
securities entitled to be included therein owned by each selling Holder or in
such other proportions as shall mutually be agreed to by such selling Holders).

              4.7 Delay of Registration. No Holder shall have any right to
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 4.

              4.8 Indemnification. With respect to the Registration Statement
and in the event any Registrable Securities are included in a registration
statement under Section 4.2(b) hereof:

                  (a) To the extent permitted by law, the Company will indemnify
and hold harmless the Investor, any Holder, or any underwriter (as defined in
the Act) for such Holder, each person, if any, who controls such Holder or
underwriter within the meaning of the Act or the Securities Exchange Act of
1934, as amended (the "1934 Act"), and each officer, director or agent of the
Holder against any losses, claims, damages, or liabilities (joint or several) to
which they, or any of them, may become subject under the Act, the 1934 Act or
other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"Violation"): (i) any untrue statement or alleged untrue statement of a material
fact contained in the relevant registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
made therein not misleading, or (iii) any violation or alleged violation by the
Company of the Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the Act, the 1934 Act or any state securities law
applicable to the Company in connection with any such registration; and the
Company will pay to the Investor or each such Holder, underwriter, controlling
person, officer, director or agent, as incurred, any legal or other expenses
reasonably incurred by them or any of them in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this subsection 4.8(a) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability, or
action if such settlement is effected without the consent of the Company (which
consent shall not be unreasonably withheld), nor shall the
<PAGE>
 
                                     - 13 -


Company be liable in any such case for any such loss, claim, damage, liability,
or action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by any such Holder,
underwriter, controlling person, officer, director or agent.

                  (b) To the extent permitted by law, the Investor and any
Holder will indemnify and hold harmless the Company, each of its directors, each
of its officers who has signed the registration statement, each person, if any,
who controls the Company within the meaning of the Act, any underwriter, any
other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereto) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished by the Investor or any
Holder, as applicable, expressly for use in connection with such registration;
and the Investor or any Holder, as applicable, will pay, as incurred, any legal
or other expenses reasonably incurred by any person intended to be indemnified
pursuant to this subsection 4.8(b) in connection with investigating or defending
any such loss, claim, damage, liability, or action; provided, however, that the
indemnity agreement contained in this subsection 4.8(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Investor or any
Holder, as applicable, which consent shall not be unreasonably withheld.

                  (c) Promptly after receipt by an indemnified party under this
Section 4.8 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 4, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party
<PAGE>
 
                                     - 14 -


by the counsel retained by the indemnifying party would be inappropriate due to
actual or potential differing interests between such indemnified party and any
other party represented by such counsel in such proceeding. The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 4.8, but omission so to deliver written
notice to the indemnifying party will not relieve it of any liability that it
may have to any indemnified party otherwise than under this Section 4.8.

                  (d) The obligations of the Company, the Investor and any
Holders under this Section 4.8 shall survive the completion of any offering of
Registrable Securities in a registration statement under this Section 4, and
otherwise.

              4.9 Reports Under Securities Exchange Act of 1934. With a view to
making available to the Holders of Registrable Securities the benefits of Rule
144 promulgated under the Act (Rule "144") and any other rule or regulation of
the SEC that may at any time permit a Holder to sell securities of the Company
to the public without registration or pursuant to a registration on Form S-3,
the Company agrees on and after the Closing that it will:

                  (a) Make and keep public information available, as those terms
are understood and defined in Rule 144;

                  (b) Use its best efforts to enable the Holders to utilize Form
S-3 for the sale of their Registrable Securities and, at such time that Form S-3
can be utilized, to replace the Registration Statement with a registration
statement on said Form S-3;

                  (c) File with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act;

                  (d) Furnish to any Holder of Registrable Securities, so long
as the Holder owns Registrable Securities representing one percent (1%) or more
of the Company's Common Stock, (i) forthwith upon request a written statement by
the Company that it has complied with the reporting requirements of Rule 144,
the Act and the 1934 Act (to the extent that the Company has so complied), or
that it qualifies as a registrant whose securities may be resold pursuant to
Form S-3 (at any time after it so qualifies), (ii) substantially concurrently
with the filing 
<PAGE>
 
                                     - 15 -


thereof, copies of the annual and quarterly reports of the Company, filed with
the SEC and such other reports and documents so filed by the Company, (iii) as
soon as they shall become available to the Company, any and all audited
financial statements of the Company and management letters from the Company's
independent auditors and the Company's response thereto, and (iv) such other
information as may be reasonably requested in availing any Holder of Registrable
Securities of any rule or regulations or the SEC which permits the selling of
any such securities without registration or pursuant to such form; and

                  (e) Not terminate the registration statement relating to the
Registrable Securities prior to the third anniversary of the date hereof unless
and until in the opinion of counsel for the Company, which opinion shall be
reasonably satisfactory to the Holder and its counsel, the Holder has the right
to sell the Registrable Securities immediately under Rule 144(k) of the Act.

      4.10 Assignment of Registration Rights. The rights to cause the Company to
register Registrable Securities pursuant to Section 4.2(b) hereof may be
assigned by a Holder of Registrable Securities to a transferee or assignee of
such securities provided the Company is, prior to or simultaneously with such
transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; and provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Act.

      4.11    Amendment of Registration Rights.

              Any provision of this Section 4 pertaining to Registrable
Securities may be amended and the observance thereof may be waived (either
generally or in a particular instance and either retroactively or prospectively)
only with the written consent of the Company and the holders of a majority of
the Registrable Securities then outstanding. Any amendment or waiver effected in
accordance with this paragraph shall be binding upon each holder of any
securities purchased under this Agreement at the time outstanding (including
securities into which such securities are convertible), each future holder of
all such securities, and the Company.

      5. Covenants of the Company. The Company hereby covenants and agrees, that
so long as the Investor owns any Securities:

      6. Right to Put Shares.

      6.1 Right to Put. On the terms and conditions herein set forth, the
Investor shall have the right to sell the Company, and the Company agrees to
purchase from the Investor, all Securities held at that time (the "Put"), for
the Put Price.

      6.2 Method of Exercise. On the terms and conditions herein set forth, the
Investor may exercise its rights hereunder to sell all Securities held by the
Investor at that time by delivering to the Company a notice of Put (a "Notice of
Put") in the form attached hereto as Exhibit D.

      6.3 Time of Exercise. At any time prior to the Expiration Date, the rights
of the Investor to Put its Securities shall become exercisable at any time, and
each time, that either (i) the Company or any Permitted Successor, as the case

the Company fails to provide the Investor with such a notice when required, the

exercises its rights pursuant to this Section 6.5, the term "Securities" as used
in clauses (ii)(x) and (ii)(y) of the definition of Put Price in Section 8
hereof shall be deemed to include the Class III Securities, and the phrase "and
