Item 1 - SECURITY AND ISSUER
- ----------------------------

     This statement relates to the Common Stock, $0.01 par value per share
("Common Stock"), of Alliance Imaging, Inc., a Delaware corporation
("Alliance"), having its principal executive offices at 3111 North Tustin
Avenue, Orange, California  92865.

Item 2 - IDENTITY AND BACKGROUND
- --------------------------------

     This statement is filed by General Electric Company, a New York corporation
("GE") with principal executive offices located at 3135 Easton Turnpike,
Fairfield, Connecticut.  GE engages in providing a wide variety of industrial,
commercial and consumer products and services.

     For information with respect to the identity and background of each
director and executive officer of GE, see Schedule I attached hereto.

     During the last five years, neither GE nor, to its best knowledge, any
person identified on Schedule I has, except as set forth on Schedule II hereto
(a) been convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors) or (b) been a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction as a result of which GE or such
person, as the case may be, was or is subject to a judgment, decree or final
order enjoining future violations of, or prohibiting or mandating activities
subject to, federal or state securities laws or finding any violation
withrespect to such laws.

     To the best knowledge of GE, all persons identified on Schedule I are
United States citizens, except that Paolo Fresco, Vice Chairman of the Board and
an executive officer of GE, is an Italian citizen and Claudio X. Gonzalez, a
director of GE, is a Mexican citizen.

Item 3 - SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION
- ----------------------------------------------------------

     On December 31, 1996, GE acquired a Senior Bridge Note of Alliance, a copy
of which is attached as Exhibit 1 hereto (the "Note").  The Note was issued to
GE to evidence an unsecured loan made by GE in the amount of $18,000,000
pursuant to a Bridge Loan Agreement dated as of December 31, 1996 (the "Bridge
Loan Agreement") between GE and Alliance, a copy of which is attached as Exhibit
2 hereto.  The maturity date of the Note is February 28, 1997, but under certain
circumstances GE may, at its option, extend the maturity date to March 31, 1997.

     GE may, at its election (the "Conversion Option") at any time prior to
February 28, 1997, enter into a series of transactions with Alliance
(collectively, the "Conversion Transactions").  The Conversion Transactions
include (i) the conversion of the Note into 18,000 shares of Alliance's Series D
4% Cumulative Redeemable Convertible Preferred Stock (the "Series D Preferred
Stock") and (ii) the conversion of $9,000,000 in principal amount due to GE
under the Note Purchase Agreement dated as of April 14, 1989, as amended to the
date hereof (the "Note Purchase Agreement") currently evidenced by a 7.5% Senior
Note Due 2003 (the "Senior Note") into a note evidenced by a senior note (the
"Convertible Senior Note") convertible, under certain circumstances, into shares
of Alliance's Series E 4% Cumulative Redeemable Convertible Preferred Stock (the
"Series E Preferred Stock").  If GE does not timely elect to exercise the
Conversion Option, then the maturity date with respect to the Note will
automatically be 
<PAGE>
 
extended to March 31, 1997, and GE's Conversion Option will
lapse; provided, however, that if for any reason all or part of the outstanding
       --------  -------                                                       
principal under the Note is still unpaid after the maturity date (as extended,
if applicable), then GE shall at and after such time have the Conversion Option.

     The rights, terms, and privileges of the Series D Preferred Stock are set
forth in a Certificate of Designation (the "Series D Certificate of
Designation"), a copy of which is attached hereto as Exhibit 3.  The Series D
Preferred Stock is nonvoting preferred stock.  Each share of Series D Preferred
Stock is convertible at any time through December 31, 2006 at the holder's
option into shares of Alliance Common Stock at a conversion price of $6.00 per
share of Common Stock (with such conversion price being subject to certain
adjustments).  Accordingly, if GE were to exercise the Conversion Option, and
then immediately exercise its right to convert its shares of Series D Preferred
Stock into Common Stock, GE would be entitled to approximately 3,000,000 shares
of Alliance Common Stock on account of its original loan under the Bridge Loan
Agreement (assuming no interim adjustments in the conversion price).  Under the
terms of the Series D Certificate of Designation, each holder has the right
under certain circumstances to require Alliance to repurchase or redeem all or
part of the shares of Series D Preferred Stock held by such holder, subject to
certain conditions (and in certain cases, at a price premium to the face amount
of each such share).  In addition, under certain conditions, Alliance has the
right to redeem the outstanding shares of Series D Preferred Stock (in certain
cases, at a price premium to the face amount of each such share).

     The foregoing response to this Item 3 is qualified in its entirety by
reference to the Note, the Bridge Loan Agreement, and the Series D Certificate
of Designation, each of which is hereby incorporated herein.

Item 4 - PURPOSE OF TRANSACTION
- -------------------------------

     GE has made the loan evidenced by the Note to provide Alliance funds solely
(i) to make certain payments due from Alliance to the holders of its Series A
Preferred Stock and Alliance's 7.50% Senior Subordinated Debentures due 2005,
(ii) to make payments with respect to certain transaction costs incurred by GE,
and (iii) to the extent any proceeds remain after the payments set forth in
items (i) and (ii) above, for general working capital purposes.  GE has acquired
its rights under the Bridge Loan Agreement and the Note (including, to the
extent applicable, its rights thereunder to acquire Common Stock of Alliance) as
a possible future investment in the ordinary course of business, and not with
the purpose of changing control of Alliance.  GE intends to review on a
continuing basis its loan to Alliance, including Alliance's business, financial
condition and operating results and general market and industry conditions and,
based upon such review, will determine whether or not to enter into the
Conversion Transactions or other transactions relating to the securities of
Alliance.

     GE may change its current intentions, acquire additional Common Stock or
rights that are convertible into or exercisable for Common Stock or take any
other action with respect to Alliance or any of its debt or equity securities in
any manner permitted by law.  Other than as set forth herein, GE has no current
plans which relate to or would result in any of the events described in Items
(a) through (j) of the instructions to this Item 4 of Schedule 13D.

Item 5 - INTEREST IN SECURITIES OF THE ISSUER
- ---------------------------------------------
<PAGE>
 
     (a) The responses to Item 3 and Item 6 are incorporated by reference
herein.  Under the assumptions set forth in those Items, GE has the right to
acquire approximately 4,550,000 shares of Common Stock (representing 29.5% of
the shares of Common Stock that as a result of the issuance of the foregoing
shares would be outstanding, based on 10,867,388 shares of Common Stock reported
by Alliance as outstanding as of October 31, 1996), which number is subject to
adjustment under various circumstances.

     (b) GE has sole voting and investment power with respect to the securities
that are the subject of this Schedule 13D.

     (c) On November 6, 1996, Alliance issued to GE a warrant (the "Warrant") to
purchase an aggregate of 50,000 shares of Common Stock.  The Warrant has a term
of three years and an exercise price per share equal to $5.00 (subject to
certain adjustments).

     (d) No other person is known to GE to have the right to receive or the
power to direct the receipt of dividends from, or any proceeds from the sale of,
the securities that are the subject of this Schedule 13D.

     (e)  Not applicable.

Item 6 - CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
- ------------------------------------------------------------------------------
     TO SECURITIES OF THE ISSUER
     ---------------------------

     The current principal balance due to GE from Alliance with respect to the
loan evidenced by the Senior Note under the Note Purchase Agreement is
approximately $9,000,000.  If GE exercises its Conversion Option, the Note
Purchase Agreement shall be amended and the Senior Note shall be converted into
the Convertible Senior Note.  The Convertible Senior Note, if and when issued,
shall be convertible at GE's option any time after January 1, 1998 into shares
of Alliance Series E Preferred Stock.  The rights, terms, and privileges of the
Series E Preferred Stock are set forth in a Certificate of Designation (the
"Series E Certificate of Designation").  The Series E Preferred Stock is
nonvoting preferred stock.  Each share of Series E Preferred Stock, if and when
issued, shall be convertible at any time through December 31, 2006 at the
holder's option into shares of Alliance Common Stock at a conversion price (the
"Conversion Price") equal to the greater of (i) the Market Price as of the issue
date (as defined in the Series E Certificate of Designation) and (ii) the Base
Conversion Price (initially, $6 per share of Common Stock), subject to certain
adjustments.  Accordingly, if GE were to exercise the Conversion Option, and
then immediately after January 1, 1998, exercise its right to convert the
outstanding principal amount due under the Convertible Senior Note into Series E
Preferred Stock, and then immediately exercise its right to convert the shares
of Series E Preferred Stock into Common Stock, GE would be entitled to
approximately 1,500,000 shares of Alliance Common Stock on account of the
conversion of the debt evidenced by the Senior Note into Common Stock (assuming
the Conversion Price was $6.00 per share).  Under the terms of the Series E
Certificate of Designation, each holder under certain circumstances will have
the right to require Alliance to repurchase or redeem all or part of the shares
of Series E Preferred Stock held by such holder, subject to certain conditions
(and in certain cases, at a price premium to the face amount of each such
share).  In addition, under certain conditions, Alliance has the right to redeem
the outstanding shares of Series E Preferred Stock (in certain cases, at a price
premium to the face amount of each such share).
<PAGE>
 
     On November 6, 1996, Alliance issued to GE a warrant (the "Warrant") to
purchase an aggregate of 50,000 shares of Common Stock.  The Warrant has a term
of three years and an exercise price per share equal to $5.00 (subject to
certain adjustments).

     Alliance has granted GE certain registration rights with respect to the
shares of Common Stock issuable upon exercise of the Warrant, and has agreed to
provide registration rights with respect to the shares of Common Stock issuable
upon conversion of the Series D Preferred Stock and the Series E Preferred
Stock.

                                 RECENT GE CONVICTIONS
                                 ---------------------



1.   United States ex rel. Taxpayers Against Fraud and Chester L. Walsh v.
     ---------------------------------------------------------------------
     General Electric Company
     ------------------------

     On November 15, 1990, an action under the federal False Claims Act, 31
U.S.C. (S)(S) 3729-32, was filed under seal against General Electric Company
("GE") in the United States District Court for the Southern District of Ohio.
The qui tam action, brought by an organization called Taxpayers Against Fraud
and an employee of GE's Aircraft Engines division ("GEAE"), alleged that GEAE,
in connection with its sales of F110 aircraft engines and support equipment to
Israel, made false statements to the Israeli Ministry of Defense (MoD), causing
MoD to submit false claims to the United States Department of Defense under the
Foreign Military Sales Program.  Senior GE management became aware of possible
misconduct in GEAE's Israeli F110 program in December 1990.  Before learning of
the sealed qui tam suit, GE immediately made a voluntary disclosure to the
Departments of Defense and Justice, promised full cooperation and restitution,
and began an internal investigation.  In August 1991, the federal court action
was unsealed, and the Department of Justice intervened and took over
responsibility for the case.

     On July 22, 1992, after GE had completed its investigation and made a
complete factual disclosure to the U.S. government as part of settlement
discussions, the United States and GE executed a settlement agreement and filed
a stipulation dismissing the civil action.  Without admitting or denying the
allegations in the complaint, GE agreed to pay $59.5 million in full settlement
of the civil fraud claims.  Also on July 22, 1992, in connection with the same
matter, the United States filed a four count information charging GE with
violations of 18 U.S.C. (S) 287 (submitting false claims against the United
States), 18 U.S.C. (S)1957 (engaging in monetary transactions in criminally
derived property), and 15 U.S.C. (S)(S) 78m(b)(2)(A) and 78ff(a) (inaccurate
books and records), and 18 U.S.C. (S) 371 (conspiracy to defraud the United
States and to commit offenses against the United States).  The same day, GE and
the United States entered a plea agreement in which GE agreed to waive
indictment, plead guilty to the information, and pay a fine of $9.5 million.  GE
was that day sentenced by the federal court in accordance with the plea
agreement.


2.   Her Majesty's Inspectorate of Pollution v. IGE Medical Systems Limited
     ----------------------------------------------------------------------
     (St. Albans Magistrates Court, St. Albans, Hertsfordshire, England, Case
     No. 04/00320181)

     In April, 1994, GEMS' U.K. subsidiary, IGE Medical Systems Limited (IGEMS)
discovered the loss of a radioactive barium source at the Radlett, England
facility.  The lost source, used to calibrate nuclear camera detectors, emits a
very low level of radiation.  IGEMS immediately reported the loss as required by
the U.K. Radioactive Substances Act.  An ensuing investigation, conducted in
cooperation with government authorities, failed to locate the source.  On July
21, 1994, Her Majesty's Inspectorate of Pollution (HMIP) charged IGEMS with
violating the Radioactive Substances Act by failing to comply with a condition
of registration.  The Act provides that a registrant like IGEMS, which "does not
comply with a limitation or condition subject to which (it) is so registered ...
shall be guilty of (a criminal) offense."  Condition 7 of IGEMS' registration
states that it "shall so far as is reasonably practicable prevent ... loss of
any registered source."

     At the beginning of trial on February 24, 1995, IGEMS entered a guilty plea
and agreed to pay of fine of 5,000(Pounds) and assessed costs of 5,754(Pounds).
The prosecutors presentation focused primarily on the 1991 change in internal
ITEMS procedures and, in particular, the source logging procedure.  The
prosecutor complimented ITEMS' investigation and efforts to locate the source
and advised the court that ITEMS had no previous violations of the Radioactive
Substances Act.  He also told the court that the Radlett plant had been
highlighted as an exemplary facility to HIMP inspectors as part of their
training.  In mitigation, ITEMS emphasized the significant infrastructure 
<PAGE>
 
and expense undertaken by ITEMS to provide security for radiation sources and
the significant effort and expense incurred in attempting to locate the missing
source.


3.   Except for the foregoing, GE has not and, to the best of GE's knowledge,
none of the directors and executive officers of GE has been, during the last
five years, convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors).

4.    GE has not and, to the best of GE's knowledge, none of the directors and
executive officers of GE has been, during the last five years, a party to a
civil proceeding of a judicial or administrative body of competent jurisdiction
and as a result of such proceeding was or is subject to a judgment, decree, or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or finding any violation
with respect to such laws.

decree of any court or other Governmental Authority.  There is no action, suit,
claim, arbitration, litigation, legal, administrative or other proceeding, or
investigation by the Borrower or any Subsidiary currently pending or that the
Borrower or any Subsidiary currently intends to initiate.  There are no judicial
or administrative actions, proceedings or investigations pending or, to the

their respective businesses, assets or products that seek to enjoin, question
the validity of, or rescind the transactions contemplated by this Agreement or

Taxes imposed upon it or any of its properties or in respect of any of its
franchises, business, income or property before any penalty shall be incurred
with respect to such Taxes, provided, however, that, unless and until
foreclosure, distraint, levy, sale or similar proceedings shall have commenced,
the Borrower need not pay or discharge any such tax so long as the validity or
amount thereof is being contested in good faith and by appropriate proceedings
and so long as any reserves or other appropriate provisions as may be required
by GAAP shall have been made therefor.

          5.3  Maintenance of Properties.  The Borrower shall maintain or
               -------------------------

appropriate repairs, renewals and replacements thereto.

          5.4  Maintenance of Insurance. The Borrower shall maintain insurance

all reasonable costs and expenses incurred by Lender in connection with:  (a)
the preparation of this Agreement (and all Exhibits and Schedules thereto), the
Senior Note, the Series D Certificate of Designation, and the Series E
Certificate of Designation; provided, however, that the Borrower's maximum
                            --------  -------

and the shares of Series E Preferred Stock, such number of its duly authorized
shares of Common Stock as shall be sufficient to effect the conversion of the

of Common Stock shall not be sufficient to effect the conversion of the then
outstanding shares of Series D Preferred Stock and Series E Preferred 

                                       28

necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purpose.

          5.7  Compliance with Note Purchase Agreement.    So long as any
               ----------------------------------------                  
portion of the Obligations has not been indefeasibly satisfied in full, Borrower
shall comply in all respects with the terms of the Note Purchase Agreement dated
as of April 14, 1989, as amended to the date hereof (the "Note Purchase
                                                          -------------
Agreement").  Without limiting the foregoing, the Borrower shall comply with all
- ---------
affirmative and negative covenants contained in the Note Purchase Agreement.

          5.8  Certain Regulatory Matters.
               --------------------------

          (a) The operations of the Borrower and its Affiliates will be
conducted in accordance with all Applicable Laws, including, without limitation,
all such laws, regulations, orders and requirements promulgated by or relating
to consumer protection, equal opportunity, health, third party reimbursement
(including Medicare and Medicaid), environmental protection, fire, zoning and
building and occupational safety matters, except for violations that
individually or in the aggregate would not and, insofar as may reasonably be
foreseen, in the future will not, have a Material Adverse Effect on the Borrower
or any Subsidiary.

          (b) Without limiting the generality of the foregoing, the Borrower and
all Affiliates shall comply in all material respects with all directives,
orders, instructions, bulletins and other announcements received from third
party payors and their agents (including without limitation Medicare carriers
and fiscal intermediaries) regarding participation in third party payment
programs, and including without limitation preparation and submission of claims
for reimbursement.  Without limiting the generality of the foregoing, the
Borrower and all Affiliates shall follow instructions recently received in a
bulletin from Blue Shield of California ("BSC") limiting reimbursement of the
services of independent physiological laboratories to Medicare beneficiaries in
BSC's region to cardiovascular studies, diagnostic ultrasound studies, and non-
invasive vascular studies, all conducted according to the common procedural
terminology ("CPT") codes listed in the most recent version of the CPT codebook
for such studies, and shall refrain from submitting claims for Medicare
reimbursement for MRI or CT studies to BSC until and unless written approval to
submit such claims is received from the medical director of BSC, unless the
Borrower or any Affiliate identifies an alternative proper resolution of such
matter that is acceptable to the Lender, in its sole discretion.  Nothing in
this Section 5.8 shall be construed as or is intended to create any third party
beneficiaries.

     regarding Borrower's insolvency; (iii) a general assignment by Borrower for
     the benefit of creditors; or (iv) Borrower applying for, or the appointment
     of, a receiver, trustee, custodian or liquidator of Borrower or any of its

Lender under the Loan Documents immediately shall be due and payable.  Upon the
occurrence and during the continuance of any Default specified in this Article

may, at its sole option, declare all sums owing to Lender under the Loan
Documents immediately due and payable.

          6.3  Repayment of Funds Advanced.    Any funds expended by Lender in
               ----------------------------

any time.  Lender's exercise of any right or remedy shall not constitute a cure
of any Default unless all sums then due and payable to Lender under the Loan
Documents are repaid and Borrower has cured all other Defaults.  No waiver shall
be implied from any failure of Lender to take, or any delay by Lender in taking,
action concerning any Default or failure of condition under the Loan Documents,

 ARTICLE VII.  LENDER'S OPTION TO EXTEND MATURITY DATE; OPTIONAL CONVERSION OF
                                  SENIOR LOAN

          7.1  Lender's Option to Extend Maturity Date.  At any time prior
               ----------------------------------------                       
to the original Maturity Date, Lender shall have the option to extend the
Maturity Date to March 31, 1997.  If Lender determines, in its sole discretion,
to extend the Maturity Date to March 31, 1997, Lender shall deliver written
notice of such election to Borrower no later than ten (10) Business Days prior
to the original Maturity Date.  Upon delivery of such notice, the Maturity Date
for all purposes under this Agreement (including without limitation, with
respect to Sections 7.2, 7.3, 7.4, and 7.5) shall be deemed to be March 31,
1997.

          7.2  Conversion of Senior Loan Prior to Maturity Date.      At any
               -------------------------------------------------            
time at or prior to the Maturity Date, Lender shall have the option, in its sole
discretion, to convert the Senior Loan into shares of Series D Preferred Stock,
and to enter into certain transactions with Borrower related thereto, as further
provided in this Section 7.2.

          (a) If Lender determines, in its sole discretion, to convert the
Senior Loan into shares of Series D Preferred Stock, and to enter into the other
Conversion Transactions (as defined below), Lender shall deliver written notice
of such election to Borrower no later than two (2) Business Days prior to the
Maturity Date in substantially the form set forth as Exhibit F hereto (the
                                                     ---------
"Conversion Notice"); provided, however, that a Conversion Notice delivered
 -----------------    --------  -------
after February 26, 1997 will not be effective if the Maturity Date is extended
to March 31, 1997 solely as a result of the Lender's not delivering the
Conversion Notice prior to the original Maturity Date (rather than the Lender's
exercise of its extension election under Section 7.1 above).  The Conversion
Notice shall set forth the effective date of the Conversion Transactions (as
defined below) (the "Conversion Date"), which date shall not be earlier than
                     ---------------
five (5) nor later than ten (10) Business Days following the date of the
Conversion Notice.

          (b) If Lender timely delivers the Conversion Notice to Borrower, then
Lender and Borrower shall consummate the following transactions (collectively,
the "Conversion Transactions") as soon as practicable after the date of the
     -----------------------
Conversion Notice, but in any event no later than the Conversion Date:

               (i) Lender and Borrower shall enter into a Series D Preferred
     Stock Purchase Agreement substantially in the form attached hereto as
     Exhibit G (with all Exhibits and Schedules thereto, and all documents to be
     ---------
     delivered thereunder (including without 

                                       31
<PAGE>
 
     limitation any legal opinions), to be satisfactory to Lender, in its sole
     discretion), and Lender and Borrower shall consummate the transactions
     contemplated thereby;

               (ii) Borrower shall pay to Lender on the Conversion Date all
     accrued interest on the Senior Loan in cash (including without limitation
     any interest accrued at the Default Rate);

               (iii)  Borrower and Lender shall enter into an Eleventh Amendment
     to the Note Purchase Agreement, substantially in the form attached hereto
     as Exhibit H, and Lender and Borrower shall consummate the transactions
        ---------
     contemplated thereby.

          (c) If Lender does not timely deliver the Conversion Notice to
Borrower pursuant to this Section 7.2, then the Maturity Date shall be extended
automatically to March 31, 1997, and the Maturity Date for all purposes under
this Agreement (including without limitation, with respect to Sections 7.2, 7.3,
7.4, and 7.5) shall be deemed to be March 31, 1997.

          7.3  Conversion of Senior Loan After Maturity Date.  If for any
               ----------------------------------------------                
reason all or part of the Senior Loan is still outstanding after the Maturity
Date, then Lender shall have the option, in its sole discretion, to convert the
Senior Loan into shares of Series D Preferred Stock, and to enter into the other
Conversion Transactions, as further provided in this Section 7.3.

          (a) If Lender determines, in its sole discretion, to convert the
Senior Loan into shares of Series D Preferred Stock, and to enter into the other
Conversion Transactions, after the Maturity Date, Lender may deliver a
Conversion Notice at any such time to Borrower.  The Conversion Notice shall set
forth the Conversion Date.

          (b) After delivery of the Conversion Notice to Borrower, Lender and
Borrower shall consummate the Conversion Transactions as soon as practicable
after the date of the Conversion Notice, but in any event no later than the
Conversion Date.

          7.4  Acknowledgement.      Lender and Borrower acknowledge and agree
               ---------------
that Lender shall under no circumstances be under any obligation to exercise its
right to elect to enter into the Conversion Transactions contemplated by this
Article 7,  that notwithstanding the provisions of this Article 7, if Lender
does not deliver the Conversion Notice, Lender shall have the absolute right at
and at any time after the Maturity Date to repayment of the Senior Loan and all
other amounts due and payable to Lender from Borrower under the Loan Documents.

          ARTICLE VIII.  MISCELLANEOUS PROVISIONS

non-receipt of any communication as the result of any change of address or
facsimile number of which the sending party was not notified or as the result of
a refusal to accept delivery shall be deemed receipt of such communication.

          8.3  Attorneys' Fees and Expenses; Enforcement.  If any attorney is
               -----------------------------------------                       
engaged by Lender to interpret, administer, enforce or defend any provision of
this Agreement or any of the other Loan Documents, or as a consequence of any
Default under the Loan Documents, with or without the filing of any legal action
or proceeding, Borrower shall immediately pay to Lender, upon demand, the amount

          8.6  Participations.  Lender may, at any time, sell, assign or grant
               --------------

such sale, assignment or participation, Lender may disseminate to any such
actual or potential servicer(s), purchaser(s), assignee(s) or participant(s) all

assignment or participation, Borrower further agrees that the Loan Documents
shall be sufficient evidence of the obligations of Borrower to each purchaser,
assignee, or participant, and upon written request by Lender, Borrower shall

reasonably required in order to evidence any such sale, assignment or
participation.  The indemnity obligations of Borrower under the Loan Documents
shall also apply with respect to any purchaser, assignee or participant.

          8.7  Severability.  If any provision or obligation under this
               ------------

competent jurisdiction to be invalid, illegal or unenforceable, that provision
shall be deemed severed from the Loan Documents and the validity, legality and
enforceability of the remaining provisions or obligations shall remain in full
force as though the invalid, illegal, or unenforceable provision had never been
a part of the Loan Documents, provided, however, that if the rate of interest or

                ----------------------------                               
waives, disclaims and renounces any right to designate the portion of the
Obligations satisfied, or deemed to be satisfied, upon payment of any of the
Obligations by any guarantor or surety of all or any portion of the Obligations,
it being the understanding and agreement of Borrower, Lender and any such
guarantor or surety that Lender may allocate any and all payments on the
Obligations so as to maximize Lender's recovery against Borrower and all
guarantors or sureties.

          8.14  Usury Savings.  It is the intention of the parties hereto to
                -------------                                                 
conform strictly to the usury and other laws relating to interest from time to
time in force, and all agreements between Borrower and Lender, whether now
existing or hereafter arising and whether oral or written, are hereby expressly
limited so that in no contingency or event whatsoever, whether by acceleration
or maturity or otherwise, shall the amount paid or agreed to be paid to Lender,
or collected by Lender for the use, forbearance or detention of the money to be
loaned under the Senior Note, this Agreement or otherwise, or for the payment or
performance of any covenant or obligation contained herein or in any of the
other Loan Documents or in any other security agreement given to secure the Loan
or in any other document evidencing, securing or pertaining to the Loan, exceed
the maximum amount of interest allowable under applicable law (the "Maximum
                                                                    -------
Amount").  If under any circumstances whatsoever fulfillment of any provision
- ------
hereof or any other Loan Document, at the time performance of such provision
shall be due, shall involve transcending the Maximum Amount, then ipso facto,
the obligation to be fulfilled shall be reduced to the Maximum Amount.  For the
purposes of calculating the actual amount of interest paid and or payable, in
respect of laws pertaining to usury or such other laws, all sums paid or agreed
to be paid to the holder of the Senior Note for the use, forbearance or
detention of the Loan shall, to the extent permitted by applicable law, be
amortized, allocated and spread from the date of disbursement of the proceeds of
the Loan until payment in full of the Loan, so that the actual rate of interest
on account of the Loan is uniform throughout the term hereof.  If under any
circumstances Lender shall ever receive an amount deemed interest by applicable
law, which would exceed the Maximum Amount, such amount that would be excessive
interest under applicable usury laws shall be deemed a payment in reduction of
the principal amount owing under the Senior Note and shall be so applied to
principal and not to the payment of interest, or if such excessive interest
exceeds the outstanding principal balance of the Loan, such excessive interest
shall be deemed to have been a payment made by mistake and shall be refunded to
Borrower or to any other person making such payment on Borrower's behalf.

          8.15  Revival.  To the extent Borrower makes a payment to Lender,
                -------                                                      
which payment or the proceeds or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee, receiver or any other party having requisite authority under the
Bankruptcy Code or any bankruptcy law, state or federal law, common law or
equitable cause, then, to the extent of such payment or proceeds received, the
obligation hereunder or part thereof intended to be satisfied shall be revived
and continue in full force and effect, as if such payment or proceeds had not
been received.

          8.16  Counterparts.  This Agreement, any of the other Loan Documents

(except for the Senior Note), and any subsequent modifications, amendments,
waivers, consents or supplements thereof, if any, may be executed in any number

an original and all such counterparts together, shall constitute one and the
same instrument.

     4.  DIVIDENDS.
         ---------

              -----------------                                        
Preferred Stock shall be entitled to receive, out of funds legally available for
such purpose, cumulative preferential cash dividends accruing from the Issue
Date at the rate of Four Percent (4%) per annum of the Face Amount per share
("Regular Dividends").

          b.  TIME OF PAYMENT.  Regular Dividends shall be cumulative from the

Issue Date and shall be payable in arrears, when and as declared by the Board,
on March 31, June 30, September 30, and December 31 of each year (each such date
being herein referred to as a "Dividend Payment Date"), commencing on March 31,
1997.  The quarterly period between consecutive Dividend Payment Dates shall

Date.  As

<PAGE>
 
used above, the term "Record Date" means, with respect to the Regular Dividend
payable on March 31, June 30, September 30 and December 31, respectively, of
each year, the preceding March 15, June 15, September 15 and December 15, or
such other record date designated by the Board of the Company with respect to
the Regular Dividend payable on such respective Dividend Payment Date. Dividends
on account of arrears for any past Dividend Periods may be declared and paid at
any time, without reference to any Dividend Payment Date, to holders of record
on such date, not exceeding 50 days preceding the payment date thereof, as may
be fixed by the Board.

          c.  ACCUMULATION.  In the event that full cash Regular Dividends are
              ------------                                                    
not paid to the holders of all outstanding shares of Series D Preferred Stock,
and funds available shall be insufficient to permit payment in full in cash to
all such holders of the preferential amounts to which they are they entitled,
the entire amount available for payment of cash dividends shall be distributed
among the holders of the Series D Preferred Stock ratably in proportion to the
full amount to which they would otherwise be respectively entitled, and any
remainder not paid in cash to the holders of the Series D Preferred Stock shall
cumulate as provided in this subsection 4(c).  If, on any Dividend Payment Date,
the holders of the Series D Preferred Stock shall not have received the full
Regular Dividends provided for in this Section 4, then such dividends shall
cumulate, whether or not earned or declared, with additional dividends thereon
to accrue at the rate of eight percent (8%) per annum for each succeeding full
Dividend Period during which such dividends shall remain unpaid.  Unpaid
dividends for any period less than a full Dividend Period shall cumulate on a
day-to-day basis and shall be computed on the basis of a 360 day year.
"Accumulated Dividends" shall mean, as of any date, all Regular Dividends that
are either undeclared or unpaid as of such date.

          d.  RESTRICTION WITH RESPECT TO JUNIOR SECURITIES.  So long as any
              ---------------------------------------------                 
Series D Preferred Stock shall remain outstanding, no cash dividend whatsoever
shall be declared or paid upon or set apart for payment on any class of Junior
Securities nor shall any shares of Junior Securities be redeemed or purchased
for cash by the Company or any parent or subsidiary thereof nor shall any moneys
be paid to or made available for a sinking fund for redemption or purchase of
any shares of Junior Securities, unless in each instance all Accumulated
Dividends with respect to all previous Dividend Payment Dates shall have been
paid; provided, however, that the restriction set forth in this Section 4(d)
      --------  -------                                                     
shall not apply to (i) up to $100,000 per calendar year applied to redemption or
purchase by the Company of Junior Securities owned by employees of the Company
in connection with the separation of such employees from their employment with
the Company, or (ii) any particular cash dividend, redemption or purchase if the
holders of a majority of then outstanding shares of Series D Preferred Stock
consent in writing to the declaration or payment of such cash dividend,
redemption or purchase, as the case may be.

     5.  LIQUIDATION PREFERENCE.
         ---------------------- 

          a.   GENERAL.  Upon a Liquidation Event, the holders of Series D
               -------                                                    
Preferred Stock then outstanding shall be entitled to be paid, out of the assets
of the Company available for distribution to its shareholders, whether from
capital, surplus or earnings ("Available Assets"), before any payment shall be
made in respect of any Junior Security, an amount equal to the Face Amount per
share plus an amount equal to all Accumulated Dividends, if any (in the
      ----                                                             
aggregate, 

                                       5
<PAGE>
 
the "Liquidation Preference Amount"). If upon a Liquidation Event, the Available
Assets shall be insufficient to pay the holders of the Series D Preferred Stock
the full Liquidation Preference Amount, the holders of the Series D Preferred
Stock shall share ratably in any distribution of assets according to the
respective amounts which would be payable in respect of the shares held by them
upon such distribution if all amounts payable on or with respect to said shares
were paid in full.

          b.  NOTICE REQUIRED.  Written notice of any voluntary or involuntary
              ---------------                                                 
Liquidation Event, stating the payment date and the place where the
distributable amount shall be payable, shall be given by mail, postage prepaid,
not less than thirty (30) days prior to the payment date stated therein, to the
holders of record of the Series D Preferred Stock at their respective addresses
as the same shall then appear on the books of the Company.

     6.  CONVERSION.
         ---------- 

          a.  EXERCISE OF CONVERSION RIGHT.  Each holder of Series D Preferred
              ----------------------------                                    
Stock shall have the right, at its option, at any time from the Issue Date
through December 31, 2006, to convert, subject to the terms and provisions of
this Section 6, all or any portion of its Series D Preferred Stock then
outstanding into such number of fully paid and non-assessable shares of Common
Stock as results from dividing (i) the sum of (A) the Face Amount of all shares
of Series D Preferred Stock to be converted plus (B) any Accumulated Dividends
on such shares, by (ii) the applicable Conversion Price (as defined below) on
the Conversion Date (as defined below).   Such conversion shall be deemed to
have been made at the close of business on the date that the certificate or
certificates for shares of Series D Preferred Stock shall have been surrendered
for conversion and written notice shall have been received as provided in
Section 6(b) (the "Conversion Date"), so that the person or persons entitled to
receive the shares of Common Stock upon conversion of such shares of Series D
Preferred Stock shall be treated for all purposes as having become the record
holder or holders of such shares of Common Stock at such time and such
conversion shall be at the Conversion Price in effect at such time.  Upon
conversion of any shares of Series D Preferred Stock pursuant to this Section 6,
the rights of the holder of such shares upon the Conversion Date shall be the
rights of a holder of Common Stock only, and each such holder shall not have any
rights in its former capacity as a holder of shares of Series D Preferred Stock.

          b.  NOTICE TO COMPANY.  In order to convert all or any portion of its
              -----------------                                                
outstanding Series D Preferred Stock into shares of Common Stock, the holder of
such Series D Preferred Stock shall deliver the shares of Series D Preferred
Stock to be converted to the Company at its principal office, together with
written notice that it elects to convert those shares of Series D Preferred
Stock into shares of Common Stock in accordance with the provisions of this
Section 6.  Such notice shall specify the number of shares of Series D Preferred
Stock to be converted and the name or names in which the holder wishes the
certificates for shares of Common Stock to be registered, together with the
address or addresses of the person or persons so named, and, if so required by
the Company, shall be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company, duly executed by the registered
holder of the shares of Series D Preferred Stock to be converted or by its
attorney duly authorized in writing.

                                       6
<PAGE>
 
          c.  DELIVERY OF CERTIFICATE.  As promptly as practicable after the
              -----------------------                                       
surrender as hereinabove provided of shares of Series D Preferred Stock for
conversion into shares of Common Stock, the Company shall deliver or cause to be
delivered to the holder, or the holder's designees, certificates representing
the number of fully paid and non-assessable shares of Common Stock into which
the shares of Series D Preferred Stock are entitled to be converted, together
with a cash adjustment in respect of any fraction of a share to which the holder
shall be entitled as provided in Section 6(d), and, if less than the entire
number of shares of Series D Preferred Stock represented by the certificate or
certificates surrendered is to be converted, a new certificate for the number of
shares of Series D Preferred Stock not so converted.  So long as any shares of
Series D Preferred Stock remain outstanding, the Company shall not close its
Common Stock transfer books.  The issuance of certificates for shares of Common
Stock upon the conversion of shares of Series D Preferred Stock shall be made
without charge to the holder for any tax in respect of the issuance of such
certificates (other than any transfer, withholding or other tax if the shares of
Common Stock are to be registered in a name different from that of the
registered holder of Series D Preferred Stock).

          d.  FRACTIONAL SHARES.  No fractional shares of Common Stock or scrip
              -----------------                                                
representing fractional shares of Common Stock shall be issued upon any
conversion of any shares of Series D Preferred Stock, but, in lieu thereof,
there shall be paid an amount in cash equal to the same fraction of the Market
Price of a whole share of Common Stock as of the Conversion Date.

          e.  RESERVATION OF SHARES.  The Company shall at all times reserve and
              ---------------------                                             
keep available out of its authorized but unissued shares of Common Stock, solely
for the purpose of effecting the conversion of shares of Series D Preferred
Stock, the full number of whole shares of Common Stock then deliverable upon the
conversion of all shares of Series D Preferred Stock then outstanding.  The
Company shall take at all times such corporate action as shall be necessary in
order that the Company may validly and legally issue fully paid and non-
assessable shares of Common Stock upon the conversion of shares of Series D
Preferred Stock in accordance with the provisions of this Section 6.

          f.  REGISTRATION.  If any shares of Common Stock to be reserved for
              ------------                                                   
the purpose of conversion of Series D Preferred Stock require registration or
listing with, or approval of, any governmental authority, stock exchange or
other regulatory body under any federal or state law or regulation or otherwise,
before such shares may be validly issued or delivered upon conversion, the
Company shall, in good faith and as expeditiously as possible, endeavor to
secure such registration, listing or approval, as the case may be.

          g.  SHARES VALIDLY ISSUED AND NON-ASSESSABLE.  All shares of Common
              ----------------------------------------                       
Stock that may be issued upon conversion of the Series D Preferred Stock shall
upon issuance by the Company be validly issued, fully paid and nonassessable and
free from all taxes, liens and charges with respect to the issuance thereof.

          h.  RETIREMENT OF SHARES.  Any shares of Series D Preferred Stock
              --------------------                                         
converted pursuant to the provisions of this Section 6 shall be retired and
given the status of authorized and unissued Preferred Stock, undesignated as to
series, subject to reissuance by the Company as 

                                       7
<PAGE>
 
shares of Preferred Stock of one or more series, as may be determined from time
to time by the Board.

     7.  CONVERSION PRICE.  As used herein, the "Conversion Price" shall
         ----------------                                               
initially be $6.00 per share of Common Stock, subject to adjustment as set forth
below.  No payment or adjustment shall be made for any dividends on the Common
Stock issuable in such conversion.  The Conversion Price shall be subject to
adjustment from time to time as follows:

          a.  COMMON STOCK ISSUED AT LESS THAN THE CONVERSION PRICE.  If the
              -----------------------------------------------------         
Company shall issue any Common Stock other than Excluded Stock (as hereinafter
defined) without consideration or for a consideration per share less than the
Conversion Price in effect immediately prior to such issuance, the Conversion
Price in effect immediately prior to each such issuance shall immediately be
reduced to the price determined by dividing (i) an amount equal to the sum of
(A) the number of shares of Common Stock outstanding immediately prior to such
issuance multiplied by the Conversion Price in effect immediately prior to such
issuance and (B) the consideration, if any, received by the Company upon such
issuance, by (ii) the total number of shares of Common Stock outstanding
immediately after such issuance.  For the purposes of any adjustment of the
Conversion Price pursuant to this Section 7(a), the following provisions shall
be applicable:

               (1) Cash.  In the case of the issuance of Common Stock for cash,
                   ----                                                        
     the amount of the consideration received by the Company shall be deemed to
     be the amount of the cash proceeds received by the Company for such Common
     Stock before deducting therefrom any discounts, commissions, taxes or other
     expenses allowed, paid or incurred by the Company for any underwriting or
     otherwise in connection with the issuance and sale thereof.

               (2) Consideration Other Than Cash.  In the case of the issuance
                   -----------------------------                              
     of Common Stock (otherwise than upon the conversion of shares of capital
     stock or other securities of the Company) for a consideration in whole or
     in part other than cash, including securities acquired in exchange therefor
     (other than securities by their terms so exchangeable), the consideration
     other than cash shall be deemed to be the fair value thereof as determined
     by the Board; provided that such fair value as determined by the Board
     shall not exceed the aggregate Market Price of the shares of Common Stock
     being issued as of the date the Board authorizes the issuance of such
     shares.

               (3) Options and Convertible Securities.  In the case of the
                   ----------------------------------                     
     issuance of (i) options, warrants or other rights to purchase or acquire
     Common Stock (whether or not at the time exercisable), (ii) securities by
     their terms convertible into or exchangeable for Common Stock (whether or
     not at the time so convertible or exchangeable) or (iii) options, warrants
     or rights to purchase such convertible or exchangeable securities (whether
     or not at the time exercisable):

                (A) the aggregate maximum number of shares of Common Stock
                deliverable upon exercise of such options, warrants or other
                rights to purchase or acquire Common Stock shall be deemed to
                have been issued 

                                       8
<PAGE>
 
                at the time such options, warrants or rights were issued and for
                a consideration equal to the consideration (determined in the
                manner provided in subsections (1) and (2) above), if any,
                received by the Company upon the issuance of such options,
                warrants or rights plus the minimum purchase price provided in
                such options, warrants or rights for the Common Stock covered
                thereby;

                (B) the aggregate maximum number of shares of Common Stock
                deliverable upon conversion of or in exchange for any such
                convertible or exchangeable securities, or upon the exercise of
                options, warrants or other rights to purchase or acquire such
                convertible or exchangeable securities and the subsequent
                conversion or exchange thereof, shall be deemed to have been
                issued at the time such securities were issued or such options,
                warrants or rights were issued and for a consideration equal to
                the consideration, if any, received by the Company for any such
                securities and related options, warrants or rights (excluding
                any cash received on account of accrued interest or accrued
                dividends), plus the additional consideration (determined in the
                manner provided in subsections (1) and (2) above), if any, to be
                received by the Company upon the conversion or exchange of such
                securities, or upon the exercise of any related options,
                warrants or rights to purchase or acquire such convertible or
                exchangeable securities and the subsequent conversion or
                exchange thereof;

                (C) on any change in the number of shares of Common Stock
                deliverable upon exercise of any such options, warrants or
                rights or conversion or exchange of such convertible or
                exchangeable securities or any change in the consideration to be
                received by the Company upon such exercise, conversion or
                exchange, including, but not limited to, a change resulting from
                the anti-dilution provisions thereof, the Conversion Price as
                then in effect shall forthwith be readjusted to such Conversion
                Price as would have been obtained had an adjustment been made
                upon the issuance of such options, warrants or rights not
                exercised prior to such change, or of such convertible or
                exchangeable securities not converted or exchanged prior to such
                change, upon the basis of such change;

                (D) on the expiration or cancellation of any such options,
                warrants or rights, or the termination of the right to convert
                or exchange such convertible or exchangeable securities, if the
                Conversion Price shall have been adjusted upon the issuance
                thereof, the Conversion Price shall forthwith be readjusted to
                such Conversion Price as would have been obtained had an
                adjustment been made upon the issuance of such options,
                warrants, rights or such convertible or exchangeable securities
                on the basis of the issuance of only the number of shares of
                Common Stock actually issued upon the exercise of such options,
                warrants or rights, or 

                                       9
<PAGE>
 
                upon the conversion or exchange of such convertible or
                exchangeable securities, if any; and

                (E) if the Conversion Price shall have been adjusted upon the
                issuance of any such options, warrants, rights or convertible or
                exchangeable securities, no further adjustment of the Conversion
                Price shall be made for the actual issuance of Common Stock upon
                the exercise, conversion, or exchange thereof;

     provided, however, that no increase in the Conversion Price shall be made
     pursuant to subsections (A) or (B) of this subsection (3).

          b.  EXCLUDED STOCK.  "Excluded Stock" shall mean (i) shares of Common
              --------------                                                   
Stock issued or reserved for issuance by the Company as a stock dividend payable
in shares of Common Stock, or upon any subdivision or split-up of the
outstanding shares of Common Stock or Series D Preferred Stock, or upon
conversion of shares of Series D Preferred Stock; (ii) shares of Common Stock
reserved for issuance under options and warrants outstanding on the date hereof;
(iii) 750,000 shares of Common Stock reserved for issuance to key employees and
directors of the Corporation pursuant to the Company's employee stock option
plan in effect as of the date hereof; (iv) shares of Series E Preferred Stock
and shares of Common Stock issuable upon the conversion thereof, and (v) 77,520
shares of Common Stock issuable upon the conversion of the shares of Series C
Convertible Preferred Stock outstanding on the date hereof.

          c.  STOCK DIVIDENDS, SUBDIVISIONS, RECLASSIFICATIONS OR COMBINATIONS.
              ----------------------------------------------------------------  
If the Company shall (i) declare a dividend or make a distribution on its Common
Stock in shares of its Common Stock, (ii) subdivide or reclassify the
outstanding shares of Common Stock into a greater number of shares, or (iii)
combine or reclassify the outstanding Common Stock into a smaller number of
shares, the Conversion Price in effect at the time of the record date for such
dividend or distribution or the effective date of such subdivision, combination
or reclassification shall be proportionately adjusted so that the holder of any
shares of Series D Preferred Stock surrendered for conversion after such date
shall be entitled to receive the number of shares of Common Stock which he would
have owned or been entitled to receive had such shares of Series D Preferred
Stock been converted immediately prior to such date.  Successive adjustments in
the Conversion Price shall be made whenever any event specified above shall
occur.

          d.  OTHER DISTRIBUTIONS.  In case the Company shall fix a record date
              -------------------                                              
for the making of a distribution to all holders of shares of its Common Stock
(i) of shares of any class other than its Common Stock, (ii) of evidence of
indebtedness of the Company or any subsidiary of the Company, (iii) of assets,
or (iv) of rights or warrants, in each such case the Conversion Price in effect
immediately prior thereto shall be reduced immediately thereafter to the price
determined by dividing (1) an amount equal to the difference resulting from (A)
the number of shares of Common Stock outstanding on such record date multiplied
by the Conversion Price per share on such record date, less (B) the fair market
value (as determined by the Board) of said shares or evidences of indebtedness
or assets or rights or warrants to be so distributed, by (2) the number of
shares of Common Stock outstanding on such record date; provided, however, that,
                                                        --------  -------       
so long as there are no Accumulated Dividends on the Series D Preferred Stock or
the Series E 

                                       10
<PAGE>
 
Preferred Stock then outstanding for any previous Dividend Payment Date, the
provisions of this Section 7(d) shall not apply to distributions consisting of
cash dividends on the shares of Common Stock up to an amount equal to 50% of
consolidated net income of the Company and its Subsidiaries as of the calendar
year immediately preceding the proposed record date for such dividend. Any
adjustment provided for by this Section 7(d) shall be made successively whenever
such a record date is fixed.

          e.  CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE.  In case of any
              ------------------------------------------------                 
consolidation with or merger of the Company with or into another corporation or
other entity, or in case of any sale, lease or conveyance to another entity of
the assets of the Company as an entirety or substantially as an entirety, each
share of Series D Preferred Stock shall after the date of such consolidation,
merger, sale, lease or conveyance be convertible into the number of shares of
stock or other securities or property (including cash) to which the Common Stock
issuable (at the time of such consolidation, merger, sale, lease or conveyance)
upon conversion of such share of Series D Preferred Stock would have been
entitled upon such consolidation, merger, sale, lease or conveyance; and in any
such case, if necessary, the provisions set forth herein with respect to the
rights and interests thereafter of the holders of the shares of Series D
Preferred Stock shall be appropriately adjusted so as to be applicable, as
nearly as may reasonably be, to any shares of stock or other securities or
property thereafter deliverable on the conversion of the shares of Series D
Preferred Stock.  Nothing in this Section 7(e) shall be construed in any way to
derogate from the right of the holders of the Series D Preferred Stock to
require the Company to repurchase their shares at the Change in Control
Repurchase Price upon a Change in Control, as set forth in Section 8(c) hereof.

          f.  NOTICE TO HOLDERS.  In the event the Company shall propose to take
              -----------------                                                 
any action of the type described in subsections (a), (c), (d), and (e) of this
Section 7, the Company shall give notice to each holder of shares of Series D
Preferred Stock, which notice shall specify the record date, if any, with
respect to any such action and the approximate date on which such action is to
take place.  Such notice shall also set forth such facts with respect thereto as
shall be reasonably necessary to indicate the effect of such action on the
Conversion Price and the number, kind or class of shares or other securities or
property which shall be deliverable upon conversion of shares of Series D
Preferred Stock.  In the case of any action which would require the fixing of a
record date, such notice shall be given at least 10 days prior to the date so
fixed, and in the case of all other action, such notice shall be given at least
15 days prior to the taking of such proposed action.

          g.  STATEMENT REGARDING ADJUSTMENTS.  Upon the occurrence of each
              -------------------------------                              
adjustment or readjustment of the Conversion Price of the Series D Preferred
Stock pursuant to this Section 7, the Company shall compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder a certificate setting forth such adjustment or readjustment and showing
in detail the facts upon which such adjustment or readjustment is based.  Each
such statement shall be signed by the Company's public accountants.

          h.  TREASURY STOCK.  For the purposes of this Section 7, the sale or
              --------------                                                  
other disposition of any Common Stock theretofore held in the Company's treasury
shall be deemed to be an issuance thereof.
