     2.1  The Company has all requisite corporate power and authority to enter
into this Agreement and, assuming satisfaction of the conditions to the
obligations of the Company set forth in Section 6 of this Agreement, to perform
all the obligations required to be performed by the Company under this

valid and legally binding obligation of the Company, enforceable as to the
Company in

                                       2

 
accordance with its terms except as limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other laws of general application
relating to or affecting enforcement of creditors' rights and equitable
remedies.  Upon issuance of the Securities at the Second Funding, the Third
Funding and the Fourth Funding:  all requisite corporate action shall have been
taken for the issuance thereof; all shares of Series D Preferred Stock then
being issued shall be, all $4.75 Warrants then being issued shall be, and all
shares of Common Stock issuable pursuant to such Securities then being issued
("Underlying Common Shares") shall be upon issuance of such Underlying Common
Shares, duly authorized, validly issued, fully paid and nonassessable and issued
without violation of and not subject to any preemptive right; and a number of
shares of authorized and unissued Common Stock of the Company equal to the
number of such Underlying Common Shares shall have been reserved for issuance
pursuant to such Securities then being issued.

     2.2  The Company will cooperate fully to provide the Special Committee
referred to in Section 6 of this Agreement with all such information and
support, including cooperation with McKenna & Company and legal counsel to the
Special Committee, as the Special Committee may reasonably require in connection
with the satisfaction of the conditions to the obligations of the Company set
forth in Section 6.  The Company will use its commercially reasonable best
efforts to satisfy as promptly as is reasonably practicable any applicable
requirements of Section 5(i)(1)(e) of Part III of Schedule D to the Bylaws of
the National Association of Securities Dealers, Inc. (the "NASD Exception").

3.  Representations of Purchasers.  Each Purchaser, severally and not jointly,
    -----------------------------                                             
represents and warrants to the Company as to himself as follows:

     3.1  Such Purchaser has all requisite authority to enter into this
Agreement and to perform all the obligations required to be performed by such
Purchaser under this Agreement.  This Agreement has been duly executed and
delivered by such Purchaser, and, upon execution and delivery by the Company and
the other Purchasers, this Agreement will be the valid and legally binding
obligation of such Purchaser, enforceable as to such Purchaser in accordance
with its terms except as limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application relating to or
affecting enforcement of creditors' rights and equitable remedies.

     3.2  Neither the Company nor any person acting or purporting to act on
behalf of the Company has offered or sold any of the Securities to such
Purchaser by means of any form of general solicitation or general advertising.
Such Purchaser is acquiring the Securities to be purchased by such Purchaser
under this Agreement solely for his own beneficial account, for investment
purposes, and not with any view to, or for resale in connection with, any
distribution of any such Securities.  Such Purchaser understands that the
Securities have not been registered under the Securities Act of 1933, as amended
(the "Act"), or any state securities laws, by reason of specific exemptions
under the provisions thereof which depend in part upon the investment intent of
such Purchaser and upon the accuracy of the other representations made by such
Purchaser in this Agreement.  Such Purchaser understands that the Company is
relying upon the

                                       3

 
representations and agreements contained in this Agreement for the purpose of
determining that the transactions contemplated by this Agreement meet the
requirements for such exemptions.

4.  Restrictive Legends.
    ------------------- 

     4.1  Each certificate or other document representing any of the Demand
Notes, shares of Series D Preferred Stock, $4.75 Warrants or shares of common
stock issuable in respect of the foregoing (collectively the "Securities" and
individually a "Security") issued pursuant to this Agreement shall be stamped or
otherwise imprinted with a restrictive legend in the form set forth on the form
of such Security as attached hereto as an exhibit (or, in the case of shares of
Series D Preferred stock or shares of common stock issuable upon conversion
thereof, an equivalent legend appropriately modified to refer to such
Securities).  In the event of any transfer or reissuance of any such Security,
the certificates or other instruments representing such Securities shall
continue to bear such legends.

     4.2  The Company hereby agrees that it will promptly deliver or cause to be
delivered a new certificate or certificates or instrument or instruments for any
Securities, which certificate or certificates or instrument or instruments will
not bear the legends referred to above, upon determination by the Company that
such Securities have been held beneficially by the holder for at least three
years and that such holder is not and has not been within the preceding three
months an affiliate of the Company.  All determinations pursuant to the
preceding sentence shall be made in accordance with Rule 144(k) under the Act or
any applicable successor rule.  In the event that a period shorter than
specified above is permitted by reason of the amendment or replacement of such
Rule 144(k), then the Company shall impose no greater restriction than the
restriction imposed as the result of such amendment or replacement.

     respect to any such default) under the provisions of any agreement or
     instrument governing or evidencing any obligations of the Company to its
     secured bank lender.

     6.2  The obligations of the Company to issue and sell the Securities to be

7.   Registration Rights.
     ------------------- 

     7.1  As used in this Section 7:

          (a) The terms "register," "registered" and "registration" refer to a
     registration effected by preparing and filing a registration statement in
     compliance with the Act, and the declaration or ordering of the
     effectiveness of such registration statement.

          (b) The term "Registrable Securities" means:  (i) any common stock of
     the Company ("Common Stock") issued, or issuable, upon the conversion of
     any Series D Preferred Stock, regardless of whether such conversion has
     taken place at any time, and (ii) any Common Stock issued, or issuable upon
     the conversion or exercise of any $4.75 Warrant, regardless of whether such
     exercise has taken place at any time, or any warrant, right or other
     security which is issued as a dividend or other distribution with respect
     to, or in exchange for or in replacement of, any Series D Preferred Stock
     or any $4.75 Warrant or, excluding in all cases, however, any Registrable
     Securities sold by a person in a transaction in which his rights under this
     Section 7 are not assigned.

          (c) The term "Holder" means any holder of Registrable Securities who
     acquired such Registrable Securities in a transaction or series of
     transactions not involving any public offering or any sale pursuant to Rule
     144 under the Act.

     7.2  The Company hereby agrees that:

          (a) If at any time or from time to time, the Company determines to
     register any of its securities, either for its own account or the account
     of a security holder or holders, (other than a registration solely to
     implement an employee benefit plan or a registration on Form S-4), the
     Company will:

               (i) promptly give to each Holder written notice thereof (which
          will include a list of the jurisdictions in which the Company intends
          to attempt to qualify such securities under the applicable blue sky
          law or other state securities laws); and

               (ii) include in such registration (and any related qualification
          under blue sky laws or other compliance), and in any underwriting
          involved therein, all the Registrable Securities specified in any
          written request or requests by any Holder received by the Company
          within twenty (20) days after such written notice is given and make
          its best efforts to qualify all the Registrable Securities specified
          in such request under the blue sky or other securities laws of any
          jurisdiction which said Holders may reasonably request.

                                       6

 
     (b) If the registration of which the Company gives notice is for a
     registered public offering involving an underwriting, the Company will so
     advise the Holders as a part of the written notice given pursuant to
     Section 7.2(a)(i) above.  In such event, the right of any Holder to
     registration pursuant to this Section 7.2 will be conditioned upon such
     Holder's participation in such underwriting and the inclusion of such
     Holder's Registrable Securities in the underwriting to the extent provided
     herein.  All Holders proposing to distribute Registrable Securities through
     such underwriting (together with the Company and the other shareholders
     distributing their securities through such underwriting) will enter into an
     underwriting agreement in customary form, satisfactory to the Company, with
     the underwriter or underwriters selected for such underwriting by the
     Company.  Notwithstanding any other provision of this Section 7.2, if the
     managing underwriter determines in good faith that marketing factors
     require a limitation of the number of shares to be underwritten for the
     accounts of holders of Registrable Securities and other securities of the
     Company entitled to registration pursuant to agreements with the Company,
     the managing underwriter may limit the number of Registrable Securities and
     other securities of the Company entitled to registration pursuant to
     agreements with the Company to be included in the registration.  The
     Company will so advise all Holders of Registrable Securities and all
     shareholders owning securities of the Company entitled to registration
     pursuant to agreements with the Company and participating in such
     registration, and the number of shares of Registrable Securities and such
     other securities that may be included in the registration and underwriting
     will be allocated (subject to the provision in the previous sentence) among
     all Holders and other shareholders in proportion, as nearly as practicable,
     to the respective amounts of Registrable Securities and such other
     securities entitled to such registration held by such Holders and other
     shareholders at the time of filing the registration statement.  No
     Registrable Securities excluded from the underwriting by reason of the
     underwriter's marketing limitation will be included in such registration.
     If any Holder disapproves of the terms of the underwriting, he may elect to
     withdraw therefrom by written notice to the Company and the managing
     underwriter.  The Registrable Securities so withdrawn will also be
     withdrawn from registration; provided, however, that, if by the withdrawal
     of such Registrable Securities or any other securities entitled to
     registration pursuant to agreements with the Company a greater number of
     Registrable Securities held by other Holders may be included in such
     registration (up to the maximum of any limitation imposed by the managing
     underwriter) then the Company will offer to all Holders and other
     shareholders who have included Registrable Securities and such other
     securities in the registration the right to include additional Registrable
     Securities or other securities in proportion to the amounts of their
     Registrable Securities and such other securities so included.

          (c) The Company shall cooperate and communicate with all Holders
     wishing to participate in any registration pursuant to this Section 7.2 so
     as to permit them a reasonable and effective opportunity to participate,
     including providing prompt notice of any stop orders and copies of all
     registration statements and prospectuses filed with the Securities and
     Exchange Commission, including any amendments, and any such other

                                       7

 
     materials and information that is provided to other participating
     securities holders.  The Company will bear all expenses of any
     registration, including filing fees, blue sky fees and expenses, accounting
     and legal fees and expenses, printing and mailing costs and other similar
     expenses, but will not bear any expenses (including fees of legal counsel)
     incurred by participating Holders and will not bear any underwriting
     discount or concession or similar sale costs with respect to Registrable
     Securities offered and sold by or for participating Holders.  The Company
     and the participating Holders will agree to indemnify each other or to
     contribute to one another on reasonable and customary terms.

8.   Other Qualified Purchasers.  The Company agrees that the Purchasers may
     --------------------------                                             
cause the Securities to be purchased at the Third Funding and/or the Fourth
Funding in whole or in part by one or more qualified substitute purchasers.  For
purposes of this Agreement, a qualified substitute purchaser is any person who
(i) is an accredited investor as defined in Regulation D under the Act and (ii)
who executes a subscription agreement containing representations regarding,
among other things, such person's financial sophistication, knowledge of and
access to information regarding the Company, which is reasonably satisfactory to
the Special Committee and its counsel.  The Company will cooperate fully to
provide access to information to any such person, subject to customary
confidentiality requirements.  Each Purchaser agrees that he will not take any
actions with respect to any proposed substitute purchasers that would require
any registration of any Securities by the Company under the Act or any other
securities laws.

9.   Miscellaneous

     9.1  Remedies Not Exclusive.  No remedy conferred by any of the specific
