               On May 28, 1996, Washington Construction Group, Inc. ("Washington
Construction") entered into a Restructuring and Merger Agreement (the
"Agreement") by and between Washington Construction and Morrison Knudsen
Corporation, a Delaware corporation ("MK").

               The Agreement provides for the merger of MK with and into 
Washington Construction. At the effective time of the merger, among other
things, (i) MK's senior creditors would receive $13.3 million in cash,

distribution of certain non-core assets including MK's investment and note
receivable from MK Rail Corporation, (ii) Washington Construction would pay in
full MK's debtor-in-possession loan, not to exceed $50.0 million, and (iii) the
holders of MK common stock would receive warrants to purchase 2,765,000 shares
of Washington Construction common stock at $12.00 per share for a term of five
years. Also at the effective time of the merger, Washington Construction's 
certificate of incorporation and bylaws would be amended and restated in the 
form attached to the Agreement.

               The merger, which is expected to be completed by September 30,
1996, will be consummated through a prepackaged plan of reorganization and is
subject to customary conditions.

                      RESTRUCTURING AND MERGER AGREEMENT

          This Restructuring and Merger Agreement, dated as of May 28, 1996
(this "Agreement"), is by and between Washington Construction Group, Inc., a
Delaware corporation (the "Purchaser"), and Morrison Knudsen Corporation, a
Delaware corporation (the "Company"). Capitalized terms not otherwise defined
have the meanings set forth in Article 11.

                                   RECITALS

          A.    The respective Boards of Directors of the Purchaser and the
Company have approved the Merger of the Company with and into the Purchaser on
the terms and subject to the conditions set forth herein.

          B.    As soon as possible after the date hereof, the Company will
amend its standalone Chapter 11 plan of reorganization (the "Standalone Plan")
and related disclosure statement (the "Standalone Disclosure Statement"), each
dated April 15, 1996, to incorporate the terms and provisions of this Agreement.

          C.    Under the Plan, unless the Agreement is terminated, the Company
will merge with and into the Purchaser (the "Merger") on the Effective Date,
with the Purchaser surviving the Merger. On the Effective Date, the Purchaser
will (i) provide $13,300,000 in cash and issue a number (presently estimated to
be approximately 24,123,000) of newly-issued shares of Surviving Corporation
Common Stock equal to 45% of the issued and outstanding shares of Surviving
Corporation Common Stock after giving effect to the shares issued pursuant to
the Plan, for distribution under the Plan and (ii) issue and deliver the
Surviving Corporation Series A Preferred Stock to a liquidating trust, which
shall hold the Surviving Corporation Series A Preferred Stock for the benefit of
creditors of the Company as set forth in the Plan. In addition, on the Effective
Date the Purchaser will repay or refinance borrowings under the Company's DIP
Facility if such borrowings do not exceed $50,000,000. Under the Plan, shares of
Company Common Stock will be converted into warrants to purchase 2,765,000
shares (subject to adjustment for rounding as provided herein) of Surviving
Corporation Common Stock.

                                   AGREEMENT

          NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and promises contained herein and for other good and
valuable consideration the receipt and adequacy of which are hereby
acknowledged, the parties hereto agree as follows:

                                       1

                                   ARTICLE 1
                            PLAN OF REORGANIZATION

          1.1   TERMS OF THE PLAN.  As used herein, the term "Plan" means a
joint plan of reorganization of the Company and the Debtor Subsidiaries that
will be based upon the Standalone Plan as modified to incorporate the terms and
provisions of this Agreement and as otherwise modified to contain such terms and
provisions as may be mutually agreed upon by the Company and Purchaser.

          1.2   SUPPORT OF THE PLAN FROM CREDITORS.  As promptly as possible
after the date hereof, subject to the fiduciary duties of the Company's Board of
Directors, the Company shall, with the cooperation and assistance of the
Purchaser and its advisors, seek the support of the terms of the Plan from the
creditors whose claims will be impaired under the Plan.

          1.3   PREPARATION OF THE DISCLOSURE STATEMENT AND SOLICITATION OF
ACCEPTANCES OF THE PLAN.  As promptly as possible after the date hereof, the
Company shall, with the cooperation and assistance of the Purchaser, prepare the
Plan and a modification of the Standalone Disclosure Statement to reflect the
Plan (as amended, the "Disclosure Statement") and all related documents,
including bankruptcy ballots (collectively with the Disclosure Statement, the
"Solicitation Materials"), necessary to solicit acceptances of the Plan from
impaired creditors of the Company (other than the plaintiffs in the litigation
against the Company commonly referred to as the Touchstone actions (the
"Touchstone Plaintiffs")) prior to the date (the "Filing Date") on which the
Company and any Subsidiaries of the Company that are debtors under the Plan (the
"Debtor Subsidiaries") file for relief under Chapter 11 of the United States
Bankruptcy Code (the "Bankruptcy Code"). The Purchaser will provide all
information regarding the Purchaser and its Subsidiaries, officers and directors
that is necessary to permit the Company to prepare the Disclosure Statement. The
information supplied by the Purchaser for inclusion in the Disclosure Statement
or any amendment or supplement thereto shall not, at the time that it is so
supplied, contain any 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 addition, the Purchaser shall promptly inform the
Company of any subsequent event or circumstance that should be disclosed so that
the Disclosure Statement does not contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein with respect to
the information supplied by the Purchaser. As soon as possible after the Plan
and Disclosure Statement and such other documents are finalized, the Company
shall mail such documents to the creditors of the Company whose claims are
impaired by the Plan (other than the Touchstone Plaintiffs) and shall commence
solicitation of acceptances of the Plan from such creditors pursuant to Section
1126(b) of the Bankruptcy Code and Bankruptcy Rule 3018(b). The solicitation
period shall expire on a date no later than

                                       2
<PAGE>
 
the minimum period required by the Bankruptcy Code, the rules under the
Bankruptcy Code (the "Bankruptcy Rules") and the Bankruptcy Court for
solicitation of acceptances of a Chapter 11 plan of reorganization. The Company
shall use its reasonable best efforts to receive acceptances of the Plan (the
"Requisite Acceptances") from a sufficient number of creditors in a sufficient
number of classes of creditors to allow the Plan to be confirmed under Chapter
11 of the Bankruptcy Code, including confirmation through the cramdown
provisions of Section 1129(b) of the Bankruptcy Code.

          1.4   PREPARATION OF CHAPTER 11 PETITIONS AND FIRST DAY ORDERS.  As
promptly as possible after the date on which the Company mails the Solicitation
Materials to its creditors, the Company shall, with the cooperation and
assistance of the Purchaser, prepare (a) petitions for relief under Chapter 11
of the Bankruptcy Code (the "Chapter 11 Petitions") for the Company and the
Debtor Subsidiaries, (b) motions for customary first-day orders and such orders
as described in the Disclosure Statement (the "First Day Orders") and (c)
notices to creditors and other parties required by the Bankruptcy Code with
respect to the filing of the Chapter 11 Petitions, the hearing for approval of
the Disclosure Statement, the hearing for confirmation of the Plan and other
matters (the "Bankruptcy Notices"). Such documents shall be prepared in
sufficient time to provide the Purchaser and its legal and financial advisors
with adequate time to review all such documents prior to the Filing Date.

          1.5   COMMENCEMENT OF CASES UNDER CHAPTER 11.  As soon as possible
after the date on which the Company obtains the Requisite Acceptances from its
creditors, the Company shall, and, subject to the terms of the Plan, shall cause
each of the Debtor Subsidiaries to, (a) file the Chapter 11 Petitions in the
United States Bankruptcy Court in the District of Delaware (the "Bankruptcy
Court") and commence cases under Chapter 11 of the Bankruptcy Code (the
"Reorganization Cases") in the Bankruptcy Court, (b) file the motions relating
to the First Day Orders and seek to obtain entry of the First Day Orders by the
Bankruptcy Court, (c) file motions for approval of the Solicitation Materials
(including if the Company deems it necessary a modification of the Solicitation
Materials in order to solicit the Company's stockholders and the Touchstone
Plaintiffs after the Filing Date), and schedule a hearing (the "Disclosure
Statement Hearing") in the Bankruptcy Court on the earliest date approved by the
Bankruptcy Court for approval of the Solicitation Materials and (d) schedule a
hearing (the "Confirmation Hearing") in the Bankruptcy Court on the earliest
date possible to consider confirmation of the Plan. As soon as possible after
the Filing Date, the Company shall send the Bankruptcy Notices to all Persons to
whom such notices are required to be sent under the Bankruptcy Code and such to
other Persons to whom it is ordered by the Bankruptcy Court to send the
Bankruptcy Notices.

          1.6   POST-PETITION SOLICITATION OF ACCEPTANCES OF THE PLAN FROM
STOCKHOLDERS.  If the Company deems it necessary to solicit approval of the Plan
from

                                       3
<PAGE>
 
the Company's stockholders and the Touchstone Plaintiffs, the Company shall, as
soon as possible following the Disclosure Statement Hearing, mail or otherwise
distribute the Solicitation Materials to the Company's stockholders and the
Touchstone Plaintiffs and commence solicitation of acceptances of the Plan from
such Persons pursuant to Section 1126(a) of the Bankruptcy Code and Bankruptcy
Rule 3018(a). The solicitation period shall be a period of time no longer than
the minimum period required by the Bankruptcy Code, the Bankruptcy Rules and the
Bankruptcy Court for solicitation of acceptances of a Chapter 11 plan of
reorganization.

          1.7   CONFIRMATION OF THE PLAN.  Upon receipt of the Requisite
Acceptances and completion of the solicitation of Company's stockholders and the
Touchstone Plaintiffs, the Company shall use its reasonable best efforts to
obtain confirmation of the Plan by the Bankruptcy Court at the Confirmation
Hearing. Upon entry of an order confirming the Plan (the "Confirmation Order"),
the Company shall use its reasonable best efforts to obtain the dismissal of any
and all appeals and motions for reconsideration filed with respect to the Plan
or with respect to the Confirmation Order. The date on which the Plan is
confirmed is referred to herein as the "Confirmation Date."

          1.8   EFFECTIVE DATE.  The Company shall cause the Plan to become
effective and the distributions provided for under the Plan (the
"Distributions") to be commenced as promptly as possible on or following the day
on which the Confirmation Order is entered if no stay of the Confirmation Order
pending appeal has been entered and all other conditions to effectiveness set
forth in the Plan shall have been satisfied or waived. The date on which the
Plan becomes effective is referred to herein as the "Effective Date."

          1.9   DIP FACILITY.  On the Effective Date, the Purchaser will repay
or refinance amounts outstanding under the Company's debtor-in-possession credit
facility (the "DIP Facility"). The Company shall enter into the DIP Facility
only on terms that are approved by the Purchaser, which approval shall not be
withheld or delayed unreasonably. The Company will notify the Purchaser of its
discussions or negotiations with potential lenders in connection with its
efforts to obtain the DIP Facility, and shall, in any such notice, indicate the
identity of the potential lenders and the terms and conditions of any proposals
or offers to provide the DIP Facility, and thereafter shall keep the Purchaser
informed, on a current basis, of the status and terms of any such proposals or
offers and the status of any such discussions or negotiations.

                                   ARTICLE 3
                     THE MERGER; CONVERSION OF SECURITIES

          3.1   THE MERGER.  On the Effective Date, in accordance with this
Agreement, the Plan and the applicable provisions of the Delaware General
Corporation Law ("Delaware Law"), the Company shall in the Merger merge with and
into Purchaser, with Purchaser being the surviving corporation in the Merger (as
such, the "Surviving Corporation"). As a result of the Merger, the separate
existence of the Company shall cease and the Purchaser shall continue as the
surviving corporation as set forth in the Merger Certificate. The Merger will be
consummated and become effective on the Effective Date upon the filing with the
Secretary of State of the State

                                       6
<PAGE>
 
of Delaware of a certificate of merger (the "Merger Certificate") as is required
by, and executed in accordance with, the relevant provisions of the Delaware
Law. The time at which the Merger becomes effective is referred to herein as the
"Effective Time."

          3.2   EFFECTS OF THE MERGER.

          (a)   The Merger shall have the effects set forth in the Delaware Law
and this Agreement. Without limiting the generality of the foregoing, and
subject thereto, at the Effective Time, the separate corporate existence of the
Company shall cease and the Purchaser shall be the Surviving Corporation and
shall have all of the rights, privileges, immunities and powers and shall be
subject to all duties and liabilities of a corporation organized under the
Delaware Law.

          (b)   Insofar as any agreement or instrument to which the Company is a
party requires by its terms the express assumption thereof by the Surviving
Corporation in connection with the Merger, this Section 3.2(b) will be deemed
without further action to constitute such assumption, provided, however, that
nothing in this Section 3.2(b) will affect the relative rights or obligations of
the parties under any other provision hereof or thereof.

          3.3   CERTIFICATE OF INCORPORATION AND BYLAWS.  The Certificate of
Incorporation of the Purchaser, as amended and restated to be in the form
attached hereto as Exhibit 1, shall be the Certificate of Incorporation of the
Surviving Corporation. The Bylaws of the Purchaser in the form attached as
Exhibit 2 shall be the Bylaws of the Surviving Corporation until amended in
accordance with applicable law.

          3.4   CONVERSION OF SECURITIES.  At the Effective Time, by virtue of
the Plan and without any action on the part of the parties hereto, the shares of
Company Common Stock issued and outstanding immediately prior to such time
(including without limitation all shares held in court-approved settlement
funds), which will be cancelled pursuant to the Plan, will be converted on a pro
rata basis into the right to receive warrants (the "Surviving Corporation
Warrants") to purchase an aggregate of 2,765,000 shares of Surviving Corporation
Common Stock (subject to adjustments for rounding as provided for herein) at an
exercise price of $12.00 per share. Without limiting the generality or effect of
Section 1.1, the Plan will provide that the Surviving Corporation Warrants will
be issued pursuant to a warrant agreement substantially in the form of Exhibit 3
hereto.

          3.5   FRACTIONAL SURVIVING CORPORATION WARRANTS.  No fractional
Surviving Corporation Warrants shall be issued in under the Plan. All fractional
Surviving Corporation Warrants that a holder of the Company Common Stock would

                                       7
<PAGE>
 
otherwise be entitled to receive shall be aggregated and rounded to the nearest
whole number of Surviving Corporation Warrants.

          3.6   EXCHANGE OF CERTIFICATES.  From and after the Effective Date,
each holder of an outstanding certificate which immediately prior to the
Effective Date represented outstanding shares of Company Common Stock shall be
entitled to receive in exchange therefor, upon surrender thereof to the
Disbursing Agent, a certificate or certificates representing the number of whole
Surviving Corporation Warrants into which such holder's shares were converted.
After the filing of the Merger Certificate, there shall be no further
registration of transfers of Company Common Stock and holders of certificates
representing Company Common Stock shall not enjoy the rights and privileges of
holders of the Company Common Stock other than to exchange the certificates for
Surviving Corporation Warrants. As soon as reasonably practicable after the
Effective Time, the Purchaser will instruct the Disbursing Agent to mail to each
holder of record of certificates representing shares of Company Common Stock (i)
a letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to such certificates shall pass, only upon proper
delivery of such certificates to the Disbursing Agent and shall be in such form
and have such other provisions as Parent may reasonably specify) and (ii)
instructions to effect the surrender of such certificates in exchange for the
Surviving Corporation Warrants.

          3.7   CANCELLATION.  Each share of Company Common Stock held in the
treasury of the Company and each share of Company Common Stock owned by any
direct or indirect wholly-owned Subsidiary of the Company immediately prior to
the Effective Time (other than shares held in court-approved settlement funds)
shall, by virtue of the Merger and without any action on the part of the holder
thereof, cease to be outstanding, be cancelled and be returned without payment
of any consideration therefor and cease to exist.

          3.8   PURCHASER COMMON STOCK.  Each share of Purchaser Common Stock
issued and outstanding or held in treasury immediately prior to the Effective
Time shall be unaffected by the Merger and shall continue to be one validly
issued, fully paid and nonassessable share of Surviving Corporation Common
Stock. Certificates which immediately prior to the Effective Time represented
issued shares of Purchaser Common Stock will, without the need for further
action by any Person, immediately after the Effective Time represent a like
number of shares of Surviving Corporation Common Stock.

          3.9   CORPORATE NAME.  The Merger Certificate will provide that the
corporate name of the Surviving Corporation will be changed to "Morrison Knudsen
Corporation."

good standing under the laws of the state of its incorporation. Each of the

as it is now being conducted, and to own, lease or operate the properties and
assets it now owns, leases or operates. Each of the Company and its Subsidiaries
is qualified to do business, is in good standing and has all required business
licenses in each jurisdiction in which its failure to obtain or maintain such
qualification, good standing or license could have a Material Adverse Effect on
the Company.

          4.2   BINDING AGREEMENT.  The Company has all requisite corporate
power and corporate authority to enter into this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement

authorized by all requisite corporate action, subject to approval of the
Company's stockholders (or the deemed approval thereof pursuant to Section 303
of the Delaware Law). This Agreement is a legal, valid and binding obligation of
the Company, enforceable against it in accordance with its terms, except as
enforcement thereof may be limited by general principles of equity (regardless
of whether such enforceability is considered in a proceeding at law or in
equity) and the effect of applicable bankruptcy, insolvency, moratorium and
other similar laws of general application relating to or affecting creditors'
rights generally, including, without limitation, the effect of statutory or
other law regarding fraudulent conveyances and preferential transfers.

          4.3   CAPITALIZATION.  The authorized capitalization of the Company
consists solely of (a) 100,000,000 shares of the Company Common Stock, of which
37,077,345 shares were issued and outstanding as of March 31, 1996 (including
the shares held in court-approved settlement funds); and (b) 10,000,000 shares
of the Company Preferred Stock, of which no shares were issued as of the date

Purchaser:

          (a)  All Tax Returns and reports required to be filed by the Purchaser
or any of its Subsidiaries have been timely filed or will be timely filed, all
such Tax Returns are true, correct and complete, and all Taxes, due or claimed
to be due from the Purchaser or any of its Subsidiaries have been paid, other

          (b)  To the best knowledge of the Purchaser, no claim has ever been
made by an authority in a jurisdiction, whether in the United States or
otherwise, where any of the Purchaser and its Subsidiaries do not file Tax
Returns that any of them is or may be subject to taxation by such jurisdiction.
The Purchaser Disclosure Schedule indicates all federal Tax Returns that have
been audited for all tax years for which the

                                      31

          (c)  Neither the Purchaser nor any of its Subsidiaries has any
liability for the Taxes of any Person other than the Purchaser or its
Subsidiaries under Regulations Section 1.1502-6 (or any similar provision of

otherwise.  None of the Purchaser and its Subsidiaries is a party to any Tax
allocation or sharing agreement.

          (d)  None of the Purchaser or its Subsidiaries has made any payments,
is obligated to make any payments, or is a party to any agreement that would

of the Code.

          (e)  There are no security interests on any of the assets of any of
the Purchaser and its Subsidiaries that arose in connection with any failure (or
alleged failure) to pay any Tax.

          (f)  The Purchaser and each Subsidiary have withheld from their
employees (and timely paid to the appropriate governmental authority) all
amounts required by the Tax withholding provisions of applicable federal, state,
local and foreign laws (including, without limitation, income, social security,
and employment Tax withholding for all types of compensation, and withholding or
payments to non-United States Persons) for all periods through the date hereof.

          (g)  None of the Purchaser and its Subsidiaries has waived any statute
of limitations in respect of Taxes or agreed to any extension of time with
respect to a Tax assessment or deficiency.

          (h)  None of the Purchaser and its Subsidiaries has filed a consent
under Code Section 341(f) (or any similar provision of federal, state, local or
foreign law) concerning collapsible corporations.

          (i)  The unpaid Taxes of the Purchaser and its Subsidiaries (A) did
not, as of the most recent fiscal month-end, exceed the reserve for Tax
liability (rather than any reserve for deferred Taxes established to reflect
timing differences between book and Tax income) set forth on the face of the
Purchaser's most recent balance sheet (rather than in any notes thereto), and
(B) do not exceed that reserve as adjusted for the passage of time through the
Effective Date in accordance with the past custom and practice of the Purchaser
and its Subsidiaries in filing their Tax Returns.

                                      32
<PAGE>

Code has occurred with respect to the Purchaser or any Subsidiary during the
past 10 years.

overall foreign loss within the meaning of Section 904(f) of the Code, or (B)
has participated in or cooperated with an international boycott within the
meaning of Section 999 of the Code.

          (l)  No Tax is required to be withheld pursuant to any provision of
federal, state, local or foreign law, including without limitation Section 1445
of the Code, as a result of any of the transactions contemplated by this
Agreement.

          (m)  Neither the Purchaser nor any Subsidiary is a lessor (or treated
as a lessor for federal income Tax purposes) of any property pursuant to the
provisions of Section 168(f)(8) of the Internal Revenue Code of 1954, as amended
and in effect before the enactment of the Tax Reform Act of 1986, or of any
property that is "tax-exempt use property" within the meaning of Section 168(h)
of the Code.

          5.12 ENVIRONMENTAL MATTERS.  Except as disclosed in the Purchaser SEC
Reports or the Purchaser Disclosure Schedule:

          (a)  Each of the Purchaser and its Subsidiaries is in compliance with
the provisions of all Environmental Laws, which compliance includes, but is not
limited to, the possession by the Purchaser or its Subsidiaries, as appropriate,
of all licenses, permits and other governmental authorizations required under
applicable Environmental Laws, and compliance with the terms and conditions
thereof where the failure to comply could, singly or in the aggregate, have a
Material Adverse Effect on the Purchaser.

          (b)  None of the Purchaser or any of its Subsidiaries has received any
communication (written or oral), whether from a Governmental Authority, employee
or otherwise, that alleges that the Purchaser or any of its Subsidiaries is not
in such compliance where the failure to comply could, singly or in the
aggregate, have a Material Adverse Effect on the Purchaser, and there are no
currently existing circum stances actually known to the executive officers of
the Purchaser that, if not corrected, could prevent such compliance in the
future.

          (c)  There are no Environmental Claims pending or, to the actual
knowledge of the executive officers of the Purchaser, threatened against the
Purchaser or any of its Subsidiaries or against any Person whose liability for
any Environmental Claim the Purchaser or any of its Subsidiaries has retained or
assumed either contractually or by operation of law that, singly or in the
aggregate, are reasonably

                                      33
<PAGE>
 
likely to have a Material Adverse Effect on the Purchaser; and to the actual
knowledge of the executive officers of the Purchaser, there is no basis for any
such claim.

          5.13 ABSENCE OF CERTAIN DEVELOPMENTS.  Except as set forth in the
Purchaser SEC Reports or the Purchaser Disclosure Statement: (a) since November
30, 1995, no event has occurred with respect to the Purchaser or any of its
Subsidiaries which has had, or which is reasonably likely to have, a Material
Adverse Effect on the Purchaser; and (b) since the date hereof, neither the
Purchaser nor any of its Subsidiaries has taken any action which would be
prohibited under Section 6.3.

regarding the Company and its subsidiaries, officers and directors that is
necessary to permit the Purchaser to prepare and file the Purchaser Proxy
Statement.  In addition, if at any time prior to the stockholders' meeting any
event or circumstance relating to the Company or any of its Subsidiaries, or any

state any material fact required to be stated therein or necessary in order to

contained in this Agreement to be untrue or inaccurate  any time from the date
hereof to the Effective Date and (ii) any material failure to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder.  The Company and the Purchaser acknowledge that they are presently
unaware of any facts that cause any representation or warranty contained in this
Agreement to be untrue or inaccurate.

          6.8  REASONABLE BEST EFFORTS.  Subject to the terms and conditions of
this Agreement, and the fiduciary duties of their respective Board of Directors,
each of the parties hereto agrees to use its reasonable best efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the

                                      38
<PAGE>
 
transactions contemplated by this Agreement.  Each party shall promptly consult
with the other with respect to, provide any necessary information with respect
to and provide the other (or its counsel) copies of, all filings made by such
party with the Bankruptcy Court or with any Governmental Entity in connection
with this Agreement and the transactions contemplated hereby.  In addition, if
at any time prior to the Effective Date any event or circumstance relating to
either the Company or the Purchaser or any of their respective Subsidiaries, or
any of their respective officers or directors, should be discovered by the
Company or the Purchaser, as the case may be, and which should be set forth in
an amendment or supplement to the Disclosure Statement or the Purchaser Proxy
Statement, the discovering party shall promptly inform the other party of such
event or circumstance.

          6.9  NEW YORK STOCK EXCHANGE LISTING.  The Purchaser shall use its
reasonable best efforts to cause the Surviving Corporation Common Stock and the
Surviving Corporation Warrants to be issued under the Plan to be approved for
listing on the New York Stock Exchange, subject to official notice of issuance,
prior to the Effective Date.

          6.10 EXECUTORY CONTRACTS.  Exhibit F to the Standalone Plan lists each
of the executory contracts and unexpired leases which the Company presently
intends to reject in the Plan pursuant to Section 365 of the Bankruptcy Code in
the Reorganization Cases.  The Company shall notify the Purchaser of any
proposed changes to such exhibit.  During the pendency of the Reorganization
Cases, the Company will not assume any contract or lease listed on Exhibit F to
the Standalone Plan without the prior approval of the Purchaser (which shall not
be unreasonably withheld or delayed).
 
          6.11 EXCLUSIVITY.  The Company agrees that during the period from the
date hereof until the Effective Date (or the earlier termination of this
Agreement under Section 10.1), neither the Company nor any of its affiliates nor
any of their respective directors, officers, employees, representatives or
agents (collectively the "Restricted Parties"), shall directly or indirectly,
solicit, initiate or encourage any discussions, submissions of proposals or
offers or negotiations with, or assist or participate in, facilitate or
encourage any effort or attempt by, or otherwise cooperate in any other way
with, or participate in any negotiations or discussions with, or provide any
information or data of any nature whatsoever to, any corporation, partnership,
Person or other entity or group, other than the Purchaser and its partners,
employees, representatives, agents and affiliates, concerning any merger,
consolidation, sale of assets, sale of shares of capital stock or other equity
securities or other recapitalization, debt restructuring or similar transaction
involving the Company, a substantial portion of the assets of the Company or any
division of the Company, whether as part of a plan of reorganization or
otherwise (any such transaction, other than a transaction solely

                                      39
<PAGE>
 
involving MK Rail, being referred to herein as an "Alternative Transaction");
provided, however, that the Restricted Parties may furnish information to, or
enter into discussions or negotiations with, any Person or entity in response to
proposal for a Qualifying Alternative Transaction if, and only to the extent
that, the Company's Board of Directors, after consultation with independent
legal counsel (which may include its regularly engaged independent legal
counsel), determines in good faith that such action is required for the Board of
Directors to comply with its fiduciary obligations under applicable law.  A
"Qualifying Alternative Transaction" is an Alternative Transaction that the
Company's Board of Directors determines in good faith, after consultation with
its financial advisors, would provide aggregate consideration of at least
$15,000,000 greater than the consideration provided by the Purchaser under this
Agreement.  For purposes of the foregoing definition, the value of the
consideration provided by the Purchaser under this Agreement shall be deemed to
be $235,000,000.  The Company shall immediately inform each party with which it
is currently holding discussions or negotiations concerning an Alternative
Transaction of the execution of this Agreement and of the termination of such
discussions or negotiations.

          The Company shall immediately (and within no more than 24 hours)
notify the Purchaser if any proposal, offer, inquiry or other contact is
received by, any information is requested from, or any discussions or
negotiations are sought to be initiated or continued with, the Company in
respect of an Alternative Transaction, and shall, in any such notice to the
Purchaser, indicate the identity of the offeror and the terms and conditions of
any proposals or offers or the nature of any inquiries or contacts, and
thereafter shall keep the Purchaser informed, on a current basis, of the status
and terms of any such proposals or offers and the status of any such discussions
or negotiations.  The Company shall not release any third party from, or waive
any provision of, any confidentiality or standstill agreement to which the
Company is a party.

                                   ARTICLE 7

letter, dated May 16, 1996, of Dennis Washington with respect to his agreement
to vote his shares of Purchaser Common Stock in favor of the transactions
contemplated by this Agreement shall not have been withdrawn or revoked.

          7.4  STOCK AND WARRANTS FREELY TRADEABLE.  The Surviving Corporation
Common Stock and the Surviving Corporation Warrants to be issued in the

Securities Act, shall be freely tradeable by holders who are not Affiliates of
the Surviving Corporation or "underwriters" under the Securities Act with
respect to such securities and shall contain no restrictive legend.  The
Surviving Corporation Common Stock and the Surviving Corporation Warrants shall

          7.6  NO GOVERNMENTAL PROCEEDING OR LITIGATION.  No suit, action,

approving this Agreement and the transactions contemplated hereby, certified by
the Purchaser's corporate secretary, and a tabulation reflecting the results of
the vote of the stockholders of the Purchaser adopting this Agreement, certified
by the inspector of election for the meeting of such stockholders.

          Notwithstanding the foregoing, the Company's obligation under this
Agreement to consummate the Merger and the other transactions contemplated
hereby shall not be relieved by the failure of any of the foregoing conditions
if such failure is the result, direct or indirect, of a breach by the Company of
its obligations under this Agreement.

that the Purchaser may substitute therefor policies of at least the same

advantageous to such officers and directors, or (ii) purchase runoff extensions
under the Company's existing directors' and officers' and fiduciary liability
insurance policies, extending the period for making claims under such policies

                                      44
<PAGE>
 
therefor, the Purchaser shall purchase as much coverage as possible for 150% of

          9.3  INDEMNIFICATION.

          (a)  The Company agrees to indemnify and hold harmless the Purchaser,
Washington Corporations, Dennis Washington and their respective affiliates,
directors, officers, advisors, agents and employees (the "Indemnified Purchaser
Parties"), to the fullest extent lawful, from and against any and all claims,
actions and suits asserted against any of them, and any and all damages,
judgments, liabilities and expenses resulting from or incurred in response
thereto (including, without limitation, costs of investigating, preparing or
defending any such claim or action and reasonable legal expenses) (collectively
"Losses"), arising out of, or in connection with, the Merger or the Plan, and
the Company shall indemnify and hold harmless all present officers and directors
of the Company or any of its Subsidiaries (the "Indemnified Company Parties"
and, together with the Indemnified Purchaser Parties the "Indemnified Parties"),
to the fullest extent lawful, from and against any and all claims, actions and
suits asserted against any of them and any and all Losses resulting from or
incurred in response thereto, arising in whole of in part out of the status at
any time of any such Person as on officer or director of the Company or any of
its Subsidiaries or any action taken or omitted to be taken at any time in his
or her capacity as such, including without limitation any such action taken or
omitted to be taken in connection with this Agreement or the Plan or the
respective transactions contemplated hereby and thereby; provided, that no
Indemnified Party shall be entitled to indemnification by the Company hereunder
with respect to any Losses arising solely from the bad faith or gross negligence
(as finally determined by a court of competent jurisdiction) of such Indemnified
Party or any affiliate, director, officer or employee of such Indemnified Party.
If any action or proceeding shall be brought or asserted against any Indemnified
Party in respect of which indemnity may be sought from the Company, such
Indemnified Party shall promptly notify the Company in writing and the Company
shall assume the defense thereof, including the employment of counsel
satisfactory to the Indemnified Party and the payment of expenses as provided in
the preceding sentence.  The Indemnified Party shall have the right to employ
separate counsel in any such action, and to participate in the defense thereof,
but the fees and expenses of such counsel shall be borne by such Indemnified
Party, unless (i) the Company has agreed in writing to pay such fees and
expenses, (ii) the Company shall have failed promptly to assume the defense of
such action or proceeding or shall have failed to employ counsel reasonably
satisfactory to such Indemnified Party in any such action or proceeding, or
(iii) such Indemnified Party shall have reasonably concluded that there are
defenses available to it which are different from or additional to those
available to the Company which, if the Company and the Indemnified Party were to
be represented by the same counsel, would constitute a conflict of interest for
such counsel or

                                      45
<PAGE>
 
materially prejudice the prosecution of the defenses available to such
Indemnified Party (in which case, if such Indemnified Party notifies the Company
in writing that it elects to employ separate counsel at the expense of the
Company, the Company shall not have the right to assume the defense of such
action or proceeding on behalf of such Indemnified Party, it being agreed to and
understood that the Company shall not, in connection with any one such action or
proceeding or separate but substantially similar or related actions or
proceedings in the same jurisdiction arising out of the same general allegations
or circumstances, be liable for the fees and expenses of more than one separate
firm of attorneys (together, if appropriate, with one firm of local counsel per
jurisdiction) at any time for such Indemnified Party, which counsel or firm
shall be designated in writing by such Indemnified Party or by the Purchaser if
there is more than on Indemnified Party, provided, that in the case of clause
(c) above, the Company shall only be liable for the fees and expenses of
separate counsel with respect to such different or additional defenses and such
Indemnified Party shall instruct such separate counsel to cooperate with Company
counsel in order to reduce the fees and expenses for which the Company is
liable).  The Company shall not be liable for any settlement of such action or
proceeding effected without its prior written consent, which consent shall not
be unreasonably withheld, but if settled with its written consent, or if there
be a final judgment for the plaintiff in any such action or proceeding, the
Company agrees to indemnify and hold harmless any such Indemnified Party from
and against any Losses (to the extent stated above) by reason of such settlement
or judgment. All references in this Section 9.3(a) to the "Company" shall be
deemed to include the Surviving Corporation from and after the Effective Time.

          (b)  The provisions of Section 9.3(a) shall be in addition to, but not
duplicative of, any rights to indemnification that any of the Indemnified
Company Parties may have under the certificate of incorporation of by-laws of
the Company or any of its Subsidiaries or any agreement to which the Company or
any of its Subsidiaries is a party, which rights (except as may otherwise be
provided in the Plan) shall survive the Merger and be honored by the Surviving
Corporation and the applicable Subsidiaries thereof in accordance with their
terms.

          9.4  REGISTRATION RIGHTS.  Without limiting the generality or effect
of Section 1.1, the Plan will provide that the Surviving Corporation will on the
Effective Date enter into a registration rights agreement (the "Registration
Rights Agreement") substantially in the form of Exhibit 4 with Persons who
receive Surviving Corporation Common Stock in the Distributions and who desire
to be a party to such agreement.

to the Effective Date:

          (a)  by mutual written consent of the Purchaser and the Company;

          (b)  by either the Purchaser or the Company if (i) a court of
competent jurisdiction or Governmental Authority shall have issued a
nonappealable final order, decree or ruling or taken any other action having the
effect of permanently restraining, enjoining or otherwise prohibiting the
consummation of the Plan or the Merger (provided that the right to terminate
this Agreement under this clause (i) shall not be available to any party who has
not complied with its obligations under Section 6.8 and whose noncompliance has
materially contributed to the issuance of any such order, decree or ruling or
the taking of any such action), or (ii) the Effective Date shall not have
occurred on or before December 31, 1996;

          (c)  by the Purchaser if (i)(A) there are inaccuracies in the
representations and warranties of the Company that would have a Material Adverse
Effect on the Company, or (B) there has been a material breach on the part of
the Company in the covenants of the Company set forth herein, or any failure on
the part of the Company to comply with its material obligations hereunder, or
any other events or circumstances shall have occurred or exist (otherwise than
as the result, direct or indirect, of a breach by the Purchaser of its
obligations under this Agreement), such that, in any such case, the conditions
set forth in Article 8 cannot be satisfied on or prior to date on which all
other conditions to the effectiveness of the Plan shall have been satisfied or
waived, (ii) the Company has not received the Requisite Acceptances to the Plan
on or prior to July 1, 1996, or (iii) the Confirmation Order shall not have been
entered on or before August 31, 1996 (unless the failure of the Confirmation
Order to be entered on or before such date was the result, direct or indirect,
of actions or omissions by the Purchaser);

          (d)  by the Company if (i) (A) there are inaccuracies in the
representations and warranties of the Purchaser that would have a Material
Adverse Effect on the Purchaser or the Surviving Corporation or (B) there has
been a material breach on the part of the Purchaser in the covenants of the
Purchaser set forth herein, or any failure on the part of the Purchaser to
comply with its material obligations hereunder, or any other events or
circumstances shall have occurred or exist (otherwise than as the result, direct
or indirect, of a breach by the Company of its obligations under this
Agreement), such that, in any such case, the conditions set forth in Article 7
cannot be satisfied on or prior to the date on which all other conditions to the
effectiveness of

                                      47
<PAGE>
 
the Plan shall have been satisfied or waived, or (ii) the Purchaser's
stockholders do not approve the Merger in accordance with the applicable
requirements of the Delaware Law at the Purchaser's stockholders' meeting
contemplated by Section 6.5, or (iii) on or prior to the 35th day following
Filing Date the Company receives a firm offer with respect to a Qualifying
Alternative Transaction that, in the good faith determination of its Board of
Directors after consultation with its financial advisors and with independent
legal counsel (which may include its regularly engaged legal counsel), is
reasonably capable of being financed and would cause the Board of Directors of
the Company to violate its fiduciary duties under applicable law were it to
proceed with the Plan and the Merger under this Agreement (such an offer, an
"Offer"), and following such determinations such Offer and all documents
relating thereto, together with a written statement on behalf of the Board of
Directors of the Company that the Company intends to terminate this Agreement in
order to accept such Offer, is presented to the Purchaser and the Purchaser
declines to match or exceed such Offer within three business days following such
presentation.

          10.2  EFFECT OF TERMINATION.  In the event of a termination of this
Agreement by either the Company or the Purchaser as provided in Section 10.1,
this Agreement shall forthwith become void and there shall be no liability or
obligation on the part of the Purchaser or the Company or their respective
officers or directors (other than as provided in Section 10.3 below) except for
Sections 9.3 and 12.12.

          10.3  BREAK-UP FEES.   In the event (a) the Company (i) fails to
consummate the Merger in breach of its obligations under this Agreement, or (ii)
terminates this Agreement pursuant to Section 10.1(d)(iii) and thereafter enters
into a definitive agreement with respect to a Substantial Transaction within one
year of such termination, and (b) in either such case the Purchaser is not in
material breach of its obligations under this Agreement and, at the time of such
failure or termination, as the case may be, is ready, willing and able to
proceed to consummate the transactions hereunder, the Company shall forthwith
pay Purchaser a fee of $9,000,000 plus reimbursement of expenses as provided in
Section 10.4.  In addition, in the case of a termination pursuant to Section
10.1(d)(iii), the Company shall pay the Purchaser, promptly upon consummation of
such Substantial Transaction, the lesser of (i) $3,000,000 and (ii) 40% of the
amount by which the value of the consideration provided in the Substantial
Transaction exceeds $250,000,000.  A "Substantial Transaction" means an
Alternative Transaction involving the sale of the Company, the sale of a
majority of the stock of the Company (by means of a merger, stock sale or other

          10.4  EXPENSES. The Company shall be responsible for the payment of
all expenses incurred by the Company in connection with the Plan and the Merger,

                                      48
<PAGE>
 
including all fees of attorneys, brokers, finders, accountants, and financial
advisors, whether or not the Plan or the Merger shall be consummated.  The
Company agrees to fulfill its obligation to reimburse the Purchaser for any
reasonable out-of-pocket fees and expenses incurred by Purchaser pursuant to the
April 15, 1996 letter agreement between the Company and Purchaser; provided that
such expenses and fees incurred on or after May 16, 1996 through May 23, 1996
shall not exceed an aggregate of $150,000.  Paragraph 4 of the April 15, 1996
letter agreement is hereby terminated as of the date hereof.  In the event that
the break-up fee set forth in Section 10.3 becomes due and payable to the
Purchaser, the Company shall reimburse the Purchaser for such reasonable
documented out-of-pocket expenses and fees incurred after May 13, 1996 in an
amount not to exceed $1,000,000.

               prior to the penultimate sentence of this paragraph, which the
               Corporation may deposit to the Sinking Fund shall not exceed
               $18,000,000.  A majority of the directors of the Corporation
               present at a meeting at which a quorum is present has the
               exclusive power and authority to determine, in good faith, on the
               basis of information known to them after reasonable inquiry, (i)
               whether funds received by the Corporation are Foreign Tax Credit
               Refunds and (ii) the amount of any Foreign Tax Credit Refunds.
               The holders of the Series A Preferred Stock shall have no right
               to challenge any such determination unless such challenge is
               specifically authorized by the beneficial owners of a majority of
               the issued and outstanding shares of the Series A Preferred
               Stock.  The Corporation may, but shall not be obligated to,
               deposit funds other than Foreign Tax Credit Refunds into the
               Foreign Tax Credit Sinking Fund; provided, however, that such a
                                                --------  -------             
               deposit of funds other than Foreign Tax Credit Refunds shall be
               made only upon the affirmative vote of two-thirds of the total
               number of directors that the Corporation would have if there were
               no vacancies.  Pending distribution of the amounts in the Foreign
               Tax Credit Sinking Fund pursuant to paragraph (b)(iv)(B) of this
               Section 2, all such amounts shall be deposited into and
               maintained in an interest-bearing account at a bank or other
               depository institution at which the Corporation maintains other
               interest-

                                       5

               bearing deposit accounts.  Other than distributions made pursuant
               to paragraph (b)(iv)(B) of this Section 2, the Corporation shall
               not withdraw any funds from the Foreign Tax Credit Sinking Fund.

                       (B)  On the fifteenth day of the month following the end
               of each calendar quarter, the Corporation shall distribute to
               each holder of record of Series A Preferred Stock as of the last
               day of such calendar quarter an amount per share equal to a pro
               rata portion of (i) the total amount of Foreign Tax Credit
               Refunds deposited into the Foreign Credit Sinking Fund during the
               quarter and (ii) all interest earned on such total amount during
               the quarter. The distribution for the calendar quarter in which
               the cumulative total deposits to the sinking fund reaches
               $18,000,000 will be the final distribution with respect to the
               Series A Preferred Stock. Upon this final distribution, all
               shares of Series A Preferred Stock will be cancelled and no
               longer outstanding and will not have the status of shares of
               Series A Preferred Stock, and all rights of the holders thereof
               as stockholders of the Corporation will cease.

                       (C)  If the Series A Preferred Stock has not been
               cancelled as provided in paragraph (b)(iv)(B) of this Section 2
               by the fifth anniversary of the issuance of the Series A
               Preferred Stock, the Corporation shall, on the fifteenth day
               ("Redemption Date") of the month following the fifth anniversary
               of the issuance of the Series A Preferred Stock, redeem all the
               outstanding shares of Series A Preferred Stock at a per share
               redemption price ("Redemption Price") equal to the greater of (I)
               $1.00 or (II) a pro rata portion of the balance of the 

                                       6
<PAGE>
 
               Foreign Tax Credit Sinking Fund (including all interest earned
               thereon) as of the fifth anniversary of the issuance of the
               Series A Preferred Stock.
 
                      (D)  In the event that the Corporation redeems shares of
               Series A Preferred Stock pursuant to paragraph (b)(iv)(C) of this
               Section 2, the Corporation shall send notice of the redemption by
               first-class mail, postage prepaid, not less than 30 days prior to
               the Redemption Date, to the holders of record of the shares to be
               redeemed at their respective addresses as they shall appear in
               the records of the Corporation; provided, however, that failure
                                               --------  -------              
               to give such notice or any defect therein or in the mailing
               thereof shall not affect the validity of the proceedings for the
               redemption of any shares so to be redeemed except as to the
               holder to whom the Corporation has failed to give such notice or
               except as to the holder to whom notice was defective.  Each such
               notice shall state:  (i) the Redemption Date; (ii) the number of
               shares of Preferred Stock to be redeemed; (iii) the Redemption
               Price, and (iv) the place or places where certificates for such
               shares are to be surrendered for payment of the Redemption Price.
               Upon surrender of the certificates for the shares (properly
               endorsed or assigned for transfer, if the Board of Directors so
               requires and a notice by the Corporation so states), the
               Corporation shall redeem such shares at the Redemption Price as
               aforesaid.

                       (E)  If the Corporation has mailed the notice provided in
               paragraph (b)(iv)(D) of this Section 2, then, from and after the
               Redemption Date (unless the Corporation defaults in the payment
               of the Redemption Price, in which case such rights shall continue
               until the Redemption Price is paid), all shares of Series A
               Preferred Stock will be deemed to be cancelled and no longer
               outstanding, and 

                                       7
<PAGE>
 
               will not have the status of shares of Series A Preferred Stock,
               and all rights of the holders thereof as stockholders of the
               Corporation (except the right to receive the Redemption Price)
               will cease.

               (v)     Liquidation Preference.
                       ---------------------- 

                       (A)  In the event of any voluntary or involuntary
               liquidation, dissolution or winding up of the affairs of the
               Corporation, each holder of outstanding shares of Series A
               Preferred Stock will be entitled to be paid out of the assets of
               the Corporation available for distribution to its stockholders,
               before any payment is made or any assets distributed to the
               holders of any of the Junior Securities, an amount in cash per
               share of Series A Preferred Stock held equal to the greater of
               (I) $1.00, or (II) a pro rata portion of the remaining balance of
               the Foreign Tax Credit Sinking Fund (including all interest
               earned thereon).  If the assets of the Corporation are not
               sufficient to pay in full the liquidation payments payable to the
               holders of outstanding shares of the Series A Preferred Stock and
               any Parity Securities, then the holders of all such shares shall
               share ratably in such distribution of assets in accordance with
               the amount which would be payable on such distribution if the
               amounts to which the holders of outstanding shares of Series A
               Preferred Stock and the holders of outstanding shares of such
               Parity Securities are entitled were paid in full.

                       (B)  For the purposes of this paragraph (b)(v), neither
               the voluntary sale, conveyance, exchange or transfer (for cash,
               shares of stock, securities or other consideration) of all or
               substantially all of the property or assets of the Corporation
               nor the consolidation or merger of the Corporation with any one
               or more other corporations shall be deemed to be a voluntary or
               involuntary 

                                       8
<PAGE>
 
               liquidation, dissolution or winding up of the Corporation, unless
               such voluntary sale, conveyance, exchange or transfer shall be in
               connection with a plan of liquidation, dissolution or winding up
               of the Corporation.

               (vi)    Reacquired Shares.  Shares of Series A Preferred Stock
                       -----------------         
          that have been issued and reacquired by the Corporation in any manner,
          including shares reacquired by redemption pursuant to paragraph
          (b)(iv) of this Section 2, shall (upon compliance with any applicable
          provisions of the laws of the State of Delaware) have the status of
          authorized and unissued shares of Preferred Stock undesignated as to
          series, and may be redesignated and reissued as part of any series of
          Preferred Stock.

               (vii)   Voting Rights.  In addition to any voting rights provided
                       -------------                                            
          by law, the holders of Series A Preferred Stock have the following
          voting rights:

                       (A)  General.  Except as required in this Article IV and
                            -------      
               as otherwise required by law, shares of Series A Preferred Stock
               shall vote together with shares of Common Stock of the
               Corporation as a single class on all matters as to which the
               shares of Common Stock are entitled to vote generally. Each share
               of Series A Preferred Stock is entitled to 1/100 of a vote.

                       (B)  Voting Rights On Extraordinary Matters.  In addition
                            --------------------------------------  
               to any vote or consent of stockholders required by law, the
               approval of holders of at least two-thirds of the outstanding
               shares of Series A Preferred Stock, voting as a class, is
               required (i) to reclassify any series of Junior Securities as
               Senior Securities or Parity Securities, or (ii) to amend, repeal
               or change any of the provisions of this Restated and Amended
               Certificate of Incorporation or the provisions of this Article IV
               in any manner that would alter or change the rights, 

                                       9
<PAGE>
 
               powers, preferences or privileges of the shares of Series A
               Preferred Stock so as to affect them adversely, including,
               without limitation, changing the voting percentage required for
               approval by the holders of Series A Preferred Stock of the
               foregoing matters.

                                  ARTICLE V.

          The business and affairs of the Corporation shall be managed by or
under the direction of the Board of Directors consisting of not less than six
(6) directors nor more than twelve (12) directors, the exact number of directors
to be determined from time to time by resolution adopted by the Board of
Directors. The directors shall be divided into three classes, designated Class
I, Class II and Class III. Each class shall consist, as nearly as may be
possible, of one-third of the total number of directors constituting the entire
Board of Directors. The term of the initial Class I directors shall terminate on
the date of the 1997 annual meeting of stockholders; the term of the initial
Class II directors shall terminate on the date of the 1998 annual meeting of
stockholders; and the term of the initial Class III directors shall terminate on
the date of the 1999 annual meeting of stockholders. At each annual meeting of
stockholders beginning in 1997, successors to the class of directors whose term
expires at that annual meeting shall be elected for a three-year term. If the
number of directors is changed, any increase or decrease shall be apportioned
among the classes so as to maintain the number of directors in each class as
nearly equal as possible, and any additional directors of any class elected to
fill a vacancy resulting from an increase in such class shall hold office for a
term that shall coincide with the remaining term of that class, but in no case
will a decrease in the number of directors shorten the term of any incumbent
director. A director shall hold office until the annual meeting for the year in
which his term expires and until his successor shall be elected and shall
qualify, subject, however, to prior death, resignation, retirement,
disqualification or removal from office. Any vacancy on the Board of Directors,
howsoever 

                                       10
<PAGE>
 
resulting, may be filled by a majority of the directors then in office, even if
less than a quorum, or by a sole remaining director. Any director elected to
fill a vacancy shall hold office for a term that shall coincide with the term of
the class to which such director shall have been elected. Notwithstanding
anything to the contrary in this Restated and Amended Certificate of
Incorporation or any provisions of Bylaws of the Corporation, there shall be no
cumulative voting.

                                  ARTICLE VI.

          Any or all of the directors of the Corporation may be removed from the
Board of Directors for cause only by the affirmative vote of stockholders owning
a majority in amount of the entire capital stock of the Corporation issued and
outstanding and entitled to vote thereon.

                                 ARTICLE VII.

          Elections of directors at an annual or special meeting of stockholders
need not be by written ballot unless the Bylaws of the Corporation shall
otherwise provide.

                                 ARTICLE VIII.

          Special meetings of the stockholders of the Corporation for any
purpose or purposes may be called at any time only by a majority of the Board of
Directors or the Chief Executive Officer or the President.

                                  ARTICLE IX.

          Any action which may be taken by stockholders of the Corporation at an
annual or special meeting may not be effected except at such an annual or
special meeting by the vote required for the taking of such action, and the
right of stockholders to act by written consent is expressly denied.

                                       11
<PAGE>
 
                                  ARTICLE X.

          The officers of the Corporation shall be chosen in such a manner,
shall hold their offices for such terms and shall carry out such duties as are
determined by the Board of Directors, subject to the right of the Board of
Directors to remove any officer or officers at any time with or without cause.

                                  ARTICLE XI.

          A.     The Corporation shall indemnify to the full extent authorized
or permitted by law (as now or hereafter in effect) any person made, or
threatened to be made, a defendant or witness to any action, suit or proceeding
(whether civil or criminal or otherwise) by reason of the fact that he, his
testator or intestate, is or was a director or officer of the Corporation or by
reason of the fact that such director or officer, at the request of the
Corporation, is or was serving any other corporation, partnership, joint
venture, employee benefit plan or other enterprise, in any capacity. Nothing
contained herein shall affect any rights to indemnification to which employees
other than directors or officers may be entitled by law. No amendment or repeal
of this Section A of Article XI shall apply to or have any effect on any right
to indemnification provided hereunder with respect to any acts or omissions
occurring prior to such amendment or repeal.

          B.     No director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty by such a director as a director. Notwithstanding the foregoing
sentence, a director shall be liable to the extent provided by applicable law
(i) for any breach of the director's duty of loyalty to the Corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) pursuant to Section
174 of the GCL, or (iv) for any transaction from which such director derived an
improper personal benefit. No amendment to or repeal of this Section B of this
Article XI shall apply 

                                       12
<PAGE>
 
to or have any effect on the liability or alleged liability of any director of
the Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal.

          C.     In furtherance and not in limitation of the powers conferred by
statute:
          (i)    the Corporation may purchase and maintain insurance on behalf
     of any person who is or was a director, officer, employee or agent of the
     Corporation, or is serving at the request of the Corporation as a director,
     officer, employee or agent of another corporation, partnership, joint
     venture, trust, employee benefit plan or other enterprise against any
     liability asserted against him and incurred by him in any such capacity, or
     arising out of his status as such, whether or not the Corporation would
     have the power to indemnify him against such liability under the provisions
     of law; and

          (ii)   the Corporation may create a trust fund, grant a security
     interest and/or use other means (including, without limitation, letters of
     credit, surety bonds and/or other similar arrangements), as well as enter
     into contracts providing indemnification to the full extent authorized or
     permitted by law and including as part thereof provisions with respect to
     any or all of the foregoing to ensure the payment of such amounts as may
     become necessary to effect indemnification as provided therein, or
     elsewhere.

                                 ARTICLE XII.

          In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to adopt, repeal, alter,
amend or rescind the Bylaws of the Corporation. In addition, the Bylaws of the
Corporation may be adopted, repealed, altered, amended, or rescinded by the
affirmative vote of two-thirds of the issued and outstanding stock of the
Corporation entitled to vote thereon.

                                       13
<PAGE>
 
                                 ARTICLE XIII.

          The Corporation reserves the right to repeal, alter amend, or rescind
any provision contained in this Restated and Amended Certificate of
Incorporation, in the manner now or hereafter prescribed by statute, and all
rights conferred on stockholders herein are granted subject to this reservation.
Notwithstanding any other provision of this Restated and Amended Certificate of
Incorporation and any provisions of the Bylaws of the Corporation, any proposal
to amend or repeal Articles V, VI, VIII, IX, or XII, or this Article XIII or any
other proposal to amend this Restated and Amended Certificate of Incorporation
that is inconsistent with any provisions of Articles V, VI, VIII, IX, or XII or
this Article XIII shall require not less than the affirmative vote of two-thirds
of the issued and outstanding stock of the Corporation entitled to vote thereon.

                                 ARTICLE XIV.

          The Corporation will not issue nonvoting equity securities to the
extent prohibited by Section 1123 of the United States Bankruptcy Code;
provided, however, that this Article XIV (a) will have no further force and
effect beyond that required under Section 1123 of the United States Bankruptcy
Code, (b) will have such force and effect, if any, only for so long as such
Section 1123 is in effect and applicable to the Corporation, and (c) in all
events may be amended or eliminated in accordance with applicable law as from
time to time in effect.

          SECOND:  That this Restated and Amended Certificate of Incorporation
was duly adopted in accordance with the provisions of Sections 242 and 245 of
the GCL.

                                      OF
                         MORRISON KNUDSEN CORPORATION
                (FORMERLY WASHINGTON CONSTRUCTION GROUP, INC.)

                                   ARTICLE I

                                    OFFICES
                                    -------

          Section 1.  REGISTERED OFFICES.  The registered office shall be in the
City of Dover, County of Kent, State of Delaware.

          Section 2.  OTHER OFFICES.  The corporation may also have offices at
such other places both within and without the State of Delaware as the Board of
Directors may from time to time determine or the business of the corporation may
require.

                                  ARTICLE II

                           MEETINGS OF STOCKHOLDERS
                           ------------------------

          Section 1.  PLACE OF MEETINGS.  Meetings of stockholders shall be held
at any place within or outside the State of Delaware designated by the Board of
Directors.  In the absence of any such designation, stockholders' meetings shall
be held at the principal executive office of the corporation.

          Section 2.  ANNUAL MEETING OF STOCKHOLDERS.  The annual meeting of
stockholders shall be held on such date and at such time and place as may be
fixed by the Board of Directors and stated in the notice of the meeting, for the
purposes of electing directors and for the transaction of such other business as
is properly brought before the meeting in accordance with these Bylaws.

          To be properly brought before the annual meeting, business must be
either (i) specified in the annual notice of meeting (or any supplement or
amendment thereto) given by or at the direction of the Board of Directors, (ii)
otherwise brought before the annual meeting by or at the direction of the Board
of Directors, or (iii) otherwise brought before the annual meeting by a
stockholder.  In addition to any other applicable requirements, for business to
be brought before an annual meeting by a stockholder, the stockholder must have
given timely notice thereof in writing to the Secretary of the corporation.  To
be timely, a stockholder's notice must be delivered to or mailed and received at
the principal executive offices of the corporation, not less than fifty (50)
days nor more than seventy-five (75) days prior to the meeting; provided,
however, that in the event that less than sixty-five (65) days' notice or prior
public disclosure of the date of the annual meeting is given or made to
stockholders, notice by a stockholder to be timely must be so received not later
than the close of business on the fifteenth (15th) day following the day on
which such notice of the date of the annual meeting was mailed or such public
disclosure was made, whichever first occurs.  A stockholder's notice to the
Secretary shall set forth (a) as to each matter the stockholder proposes to
bring before the annual meeting (i) a brief description of the business desired
to be brought before

                                       1
<PAGE>
 
the annual meeting and the reasons for conducting such business at the annual
meeting, (ii) the name and record address of the stockholder proposing such
business, (iii) the class, series and number of shares of the corporation which
are beneficially owned by the stockholder, and (iv) any material interest of the
stockholder in such business and (b) as to the stockholder giving the notice (i)
the name and record address of the stockholder and (ii) the class and number of
shares of capital stock of the corporation which are beneficially owned by the
stockholder.  Notwithstanding anything in the Bylaws to the contrary, no
business shall be conducted at the annual meeting except in accordance with the
procedures set forth in this Article II, Section 2.  The officer of the
corporation presiding at an annual meeting shall, if the facts warrant,
determine and declare to the annual meeting that business was not properly
brought before the annual meeting in accordance with the provisions of this
Article II, Section 2, and if he should so determine, he shall so declare to the
annual meeting and any such business not properly brought before the meeting
shall not be transacted.  Written notice of the annual meeting stating the
place, date and hour of the annual meeting shall be given to each stockholder
entitled to vote at such meeting not less than ten (10) nor more than sixty (60)
days before the date of the meeting.

          Section 3.  QUORUM; ADJOURNED MEETINGS AND NOTICE THEREOF.  A majority
of the stock issued and outstanding and entitled to vote at any meeting of
stockholders, the holders of which are present in person or represented by
proxy, shall constitute a quorum for the transaction of business except as
otherwise provided by law, by the Certificate of Incorporation, or by these
Bylaws.  A quorum, once established, shall not be broken by the withdrawal of
enough votes to leave less than a quorum and the votes present may continue to
transact business until adjournment.  If, however, such quorum shall not be
present or represented at any meeting of the stockholders, a majority of the
voting stock represented in person or by proxy may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
shall be present or represented.  At such adjourned meeting at which a quorum
shall be present or represented, any business may be transacted which might have
been transacted at the meeting as originally notified.  If the adjournment is
for more than thirty days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote thereat.

          Section 4.  VOTING.  When a quorum is present at any meeting, the vote
of the holders of a majority of the stock having power present in person or
represented by proxy at the meeting and entitled to vote on the subject matter
shall decide any question brought before such meeting, unless the question is
one upon which by express provision of the statutes, or the Certificate of
Incorporation or these Bylaws, a different vote is required in which case such
express provisions shall govern and control the decision of such question.
Directors of the corporation shall be elected by a plurality of the votes of the
shares present in person or represented by proxy at the meeting and entitled to
vote on the election of directors.  Shares represented by proxies that reflect,
with respect to a proposal, abstentions or limited voting authority, including
"broker non-votes" (i.e., shares held by a broker or nominee which are
represented at the meeting, but with respect to which such broker or nominee is
not empowered to vote on a particular proposal or proposals) shall be counted as
shares that are present and entitled to vote for purposes of determining the
presence of a quorum.  For purposes of determining the outcome of any proposal,
shares represented by such proxies will be treated as not present and not
entitled to vote with respect to the proposal or proposals.

                                       2
<PAGE>
 
          Section 5.  PROXIES.  At each meeting of the stockholders, each
stockholder having the right to vote may vote in person or may authorize another
person or persons to act for him by proxy appointed by an instrument in writing
subscribed by such stockholder and bearing a date not more than three years
prior to said meeting, unless said instrument provides for a longer period.  All
proxies must be filed with the Secretary of the corporation at the beginning of
each meeting in order to be counted in any vote at the meeting. Each stockholder
shall have one vote for each share of stock having voting power, registered in
his name on the books of the corporation on the record date set by the Board of
Directors as provided in Article VI, Section 6 hereof.  All elections shall be
had and all questions decided by a plurality vote.

          Section 6.  SPECIAL MEETINGS.  Special meetings of the stockholders,
for any purpose, or purposes, unless otherwise prescribed by statute or by the
Certificate of Incorporation, may be called only by a majority of the Board of
Directors or the Chief Executive Officer or the President.  Business transacted
at any special meeting of stockholders shall be limited to the purposes stated
in the notice.

          Section 7.  NOTICE OF STOCKHOLDERS' MEETINGS.  Whenever stockholders
are required or permitted to take any action at a meeting, a written notice of
the meeting shall be given which notice shall state the place, date and hour of
the meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called.  The written notice of any meeting shall be given
to each stockholder entitled to vote at such meeting not less than 10 (ten) nor
more than 60 (sixty) days before the date of the meeting.  If mailed, notice is
given when deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation.

          Section 8.  MAINTENANCE AND INSPECTION OF STOCKHOLDER LIST.  The
officer who has charge of the stock ledger of the corporation shall prepare and
make, at least 10 (ten) days before every meeting of stockholders, a complete
list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least 10 (ten) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

          Section 9.  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING.
Any action which may be taken by stockholders of the corporation at an annual or
special meeting may not be effected except at such an annual or special meeting
by the vote required for the taking of such action, and the right of
stockholders to act by written consent is expressly denied.

                                   DIRECTORS
                                   ---------

          Section 1.  THE NUMBER OF DIRECTORS.  The number of directors which
shall constitute the whole Board shall be not less than six (6) directors nor
more than twelve (12) directors, the exact number of directors to be determined
from time to time by resolutions adopted by the Board of Directors.  The exact
number of directors shall be nine (9) until changed as provided in this Section
1.  The directors need not be stockholders.  Only persons who are nominated in
accordance with the following procedures shall be eligible for election as
directors.  Nominations of persons for election to the Board of Directors of the
corporation at the annual meeting may be made at such meeting by or at the
direction of the Board of Directors, by any committee or persons appointed by
the Board of Directors or by any stockholder of the corporation entitled to vote
for the election of directors at the meeting who complies with the notice
procedures set forth in this Article III, Section 1.  Such nominations by any
stockholder shall be made pursuant to timely notice in writing to the Secretary
of the corporation.  To be timely, a stockholder's notice shall be delivered to
or mailed and received at the principal executive offices of the corporation not
less than fifty (50) days nor more than seventy-five (75) days prior to the
meeting; provided, however, that in the event that less than sixty-five (65)
days notice or prior to public disclosure of the date of the meeting is given or
made to stockholders, notice by the stockholder to be timely must be so received
not later than the close of business of the fifteenth (15th) day following the
day on which such notice of the date of the meeting was mailed or such public
disclosure was made, whichever first occurs.  Such stockholder's notice to the
Secretary shall set forth (i) as to each person whom the stockholder proposes to
nominate for election or reelection as a director, (a) the name, age, business
address and residence address of the person, (b) the principal occupation or
employment of the person, (c) the class and number of shares of capital stock of
the corporation which are beneficially owned by the person, and (d) any other
information relating to the person that is required to be disclosed in
solicitations for proxies for election of directors pursuant to the Rules and
Regulations of the Securities and Exchange Commission under Section 14 of the
Securities Exchange Act of 1934, as amended; and (ii) as to the stockholder
giving the notice (a) the name and record address of the stockholder and (b) the
class and number of shares of capital stock of the corporation which are
beneficially owned by the stockholder.  The corporation may require any proposed
nominee to furnish such other information as may reasonably be required by the
corporation to determine the eligibility of such proposed nominee to serve as a
director of the corporation.  No person shall be eligible for election as a
director of the corporation unless nominated in accordance with the procedures
set forth herein.  The officer of the corporation presiding at an annual meeting
shall, if the facts warrant, determine and declare to the meeting that a
nomination was not made in accordance with the foregoing procedure, and if he
should so determine, he shall so declare to the meeting and the defective
nomination shall be disregarded.  The directors shall be elected at the annual
meeting of the stockholders, except as provided in Section 2 of this Article
III, and each director elected shall hold office until his successor is elected
and qualified; provided, however, that unless otherwise restricted by the
Certificate of Incorporation or by law, any director or the entire Board of
Directors may be removed from the Board of Directors for cause only at any
meeting of stockholders by a majority of the stock represented and entitled to
vote thereat.

          Section 2.  VACANCIES.  Vacancies on the Board of Directors by reason
of death, resignation, retirement, disqualification, removal from office, or
otherwise, and newly created

                                       4
<PAGE>
 
directorships resulting from any increase in the authorized number of directors
may be filled by a majority of the directors then in office, although less than
a quorum, or by a sole remaining director.  The directors so chosen shall hold
office for a term that shall coincide with the term of the class to which such
director shall have been elected.  If there are no directors in office, then an
election of directors may be held in the manner provided by statute.  If, at the
time of filling any vacancy or any newly created directorship, the directors
then in office shall constitute less than a majority of the whole Board (as
constituted immediately prior to any such increase), the Court of Chancery may,
upon application of any stockholder or stockholders holding at least ten percent
of the total number of the shares at the time outstanding having the right to
vote for such directors, summarily order an election to be held to fill any such
vacancies or newly created directorships, or to replace the directors chosen by
the directors then in office.

          Section 3.  POWERS.  The property and business of the corporation
shall be managed by or under the direction of its Board of Directors.  In
addition to the powers and authorities by these Bylaws expressly conferred upon
them, the Board may exercise all such powers of the corporation and do all such
lawful acts and things as are not by statute or by the Certificate of
Incorporation or by these Bylaws directed or required to be exercised or done by
the stockholders.

          Section 4.  PLACE OF DIRECTORS' MEETINGS.  The directors may hold
their meetings and have one or more offices, and keep the books of the
corporation outside of the State of Delaware.

          Section 5.  MEETINGS.  The Board of Directors of the corporation may
hold meetings, both regular and special, either within or without the State of
Delaware.  Regular meetings of the Board of Directors may be held without notice
at such time and at such place as may from time to time be determined by the
Board of Directors.  Special meetings of the Board of Directors may be called by
the Chairman of the Board of Directors, the President, or by a majority of the
Board of Directors.  Notice thereof, stating the place, date and hour of the
meeting, shall be given to each director either by mail not less than four (4)
days before the date of the meeting, or personally or by telephone, telegram,
telex or similar means of communication on twelve (12) hours' notice, or on such
shorter notice as the person or persons calling such meeting may deem necessary
or appropriate in the circumstances.

          Section 6.  QUORUM.  At all meetings of the Board of Directors a
majority of the authorized number of directors shall be necessary and sufficient
to constitute a quorum for the transaction of business, and the vote of a
majority of the directors present at any meeting at which there is a quorum,
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute, by the Certificate of Incorporation or by
these Bylaws.  If a quorum shall not be present at any meeting of the Board of
Directors, the directors present thereat may adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present.  If only one director is authorized, such sole director shall
constitute a quorum.

          Section 7.  ACTION WITHOUT MEETING.  Unless otherwise restricted by
the Certificate of Incorporation or these Bylaws, any action required or
permitted to be taken at any meeting of the Board of Directors or of any
committee thereof may be taken without a meeting, if all

                                       5
<PAGE>
 
members of the Board or committee, as the case may be, consent thereto in
writing, and the writing or writings are filed with the minutes of proceedings
of the Board or committee.

          Section 8.  TELEPHONIC MEETINGS.  Unless otherwise restricted by the
Certificate of Incorporation or these Bylaws, members of the Board of Directors,
or any committee designated by the Board of Directors, may participate in a
meeting of the Board of Directors, or any committee, by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and such participation in a
meeting shall constitute presence in person at such meeting.

          Section 9.  COMMITTEES OF DIRECTORS.  The Board of Directors may, by
resolution passed by a majority of the whole Board, designate one or more
committees, each such committee to consist of one or more of the directors of
the corporation.  The Board may designate one or more directors as alternate
members of any committee, who may replace any absent or disqualified member at
any meeting of the committee.  In the absence or disqualification of a member of
a committee, the member or members thereof present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.  Any such
committee, to the extent provided in the resolution of the Board of Directors,
shall have and may exercise all the powers and authority of the Board of
Directors in the management of the business and affairs of the corporation, and
may authorize the seal of the corporation to be affixed to all papers which may
require it; but no such committee shall have the power or authority in reference
to amending the Certificate of Incorporation, adopting an agreement of merger or
consolidation, recommending to the stockholders the sale, lease or exchange of
all or substantially all of the corporation's property and assets, recommending
to the stockholders a dissolution of the corporation or a revocation of a
dissolution, or amending the Bylaws of the corporation; and, unless the
resolution or the Certificate of Incorporation expressly so provide, no such
committee shall have the power or authority to declare a dividend or to
authorize the issuance of stock.

          Section 10. MINUTES OF COMMITTEE MEETINGS.  Each committee shall keep
regular minutes of its meetings and report the same to the Board of Directors
when required.

          Section 11. COMPENSATION OF DIRECTORS.  Unless otherwise restricted
by the Certificate of Incorporation or these Bylaws, the Board of Directors
shall have the authority to fix the compensation of directors.  The directors
may be paid their expenses, if any, of attendance at each meeting of the Board
of Directors and may be paid a fixed sum for attendance at each meeting of the
Board of Directors or a stated salary as director. No such payment shall
preclude any director from serving the corporation in any other capacity and
receiving compensation therefor.  Members of special or standing committees may
be allowed like compensation for attending committee meetings.

                                  ARTICLE IV

                                   OFFICERS
                                   --------

          Section 1.  OFFICERS.  The officers of this corporation shall be
chosen by the Board of Directors and shall include a President and a Secretary.
The corporation may also have at the discretion of the Board of Directors such
other officers as are desired, including a Chief Executive

                                       6
<PAGE>
 
Officer, a Treasurer, one or more Vice Presidents, one or more Assistant
Secretaries and Assistant Treasurers, and such other officers as may be
appointed in accordance with the provisions of Section 3 hereof.  In the event
there are two or more Vice Presidents, then one or more may be designated as
Executive Vice President, Senior Vice President, or other similar or dissimilar
title.  At the time of the election of officers, the directors may by resolution
determine the order of their rank.  Any number of offices may be held by the
same person, unless the Certificate of Incorporation or these Bylaws otherwise
provide.  The Board of Directors may also appoint a Chairman of the board who
need not be an officer of the corporation unless specifically designed as such
by the Board.

          Section 2.  ELECTION OF OFFICERS.  The Board of Directors, at its
first meeting after each annual meeting of stockholders, shall choose the
officers of the corporation.

          Section 3.  SUBORDINATE OFFICERS.  The Board of Directors may appoint
such other officers and agents as it shall deem necessary who shall hold their
offices for such terms and shall exercise such powers and perform such duties as
shall be determined from time to time by the Board.

          Section 4.  COMPENSATION OF OFFICERS.  The salaries of all officers
and agents of the corporation shall be fixed by the Board of Directors.

          Section 5.  TERM OF OFFICE; REMOVAL AND VACANCIES.  The officers of
the corporation shall hold office until their successors are chosen and qualify
in their stead.  Any officer elected or appointed by the Board of Directors may
be removed at any time by the affirmative vote of a majority of the Board of
Directors.  If the office of any officer or officers becomes vacant for any
reason, the vacancy shall be filled by the Board of Directors.

          Section 6.  CHAIRMAN OF THE BOARD.  The Chairman of the Board, if the
Board has appointed one, shall, if present, preside at all meetings of the Board
of Directors and exercise and perform such other powers and duties as may be
from time to time assigned to him by the Board of Directors or prescribed by
these Bylaws.  If there is no President or Chief Executive Officer, the Chairman
of the Board shall become the Chief Executive Officer of the corporation and
shall have the powers and duties prescribed in Section 7 of this Article IV.

          Section 7.  PRESIDENT AND CHIEF EXECUTIVE OFFICER.  Subject to such

                                   ARTICLE V

                         INDEMNIFICATION OF DIRECTORS,
                         -----------------------------
                        OFFICERS, EMPLOYEES AND AGENTS
                        ------------------------------

          (a)  The corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.  The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

          (b)  The corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor by reason of the fact that he is or was a director, officer, employee
or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation and except that no such indemnification shall
be made in respect of any claim, issue or matter as to which such person shall
have been adjudged to be liable to the corporation unless and only to the extent
that the Court of Chancery of Delaware or the court in which such action or suit
was brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such Court
of Chancery or such other court shall deem proper.

          (c)  To the extent that a director, officer, employee or agent of the
corporation shall be successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in paragraphs (a) and (b), or in defense
of any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

          (d)  Any indemnification under paragraphs (a) and (b) (unless ordered
by a court) shall be made by the corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee or agent is proper under the circumstances because he has met the
applicable standard of conduct set forth in paragraphs (a) and (b).  Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum consisting of directors

                                       9
<PAGE>
 
who were not parties to such action, suit or proceeding, or (2) if such a quorum
is not obtainable, or, even if obtainable a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders.

          (e)  Expenses (including attorneys' fees) incurred by an officer or
director in defending any civil, criminal, administrative or investigative
action, suit or proceeding may be paid by the corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the corporation as authorized in this Article V.  Such expenses (including
attorneys' fees) incurred by other employees and agents may be so paid upon such
terms and conditions, if any, as the Board of Directors deems appropriate.

          (f)  The indemnification and advancement of expenses provided by, or
granted pursuant to, the other paragraphs of this Article V shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office.

          (g)  The Board of Directors may authorize, by a vote of a majority of
a quorum of the Board of Directors, the corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liability under the provisions of this Article V.

          (h)  For the purposes of this Article V, references to "the
corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Article V with
respect to the resulting or surviving corporation as he would have with respect
to such constituent corporation if its separate existence had continued.

          (i)  For purposes of this section, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include service
as a director, officer, employee or agent of the corporation which imposes
duties on, or involves services by, such director, officer, employee or agent
with respect to an employee benefit plan, its participants or beneficiaries; and
a person who acted in good faith and in a manner he reasonably believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the corporation" as referred to in this section.

                                      10
<PAGE>
 
          (j)  The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article V shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

          (k)  The corporation shall be required to indemnify a person in
connection with a proceeding (or part thereof) initiated by such person only if
the proceeding (or part thereof) was authorized by the Board of Directors of the
corporation.

                                  ARTICLE VI

                             CERTIFICATES OF STOCK
                             ---------------------

          Section 1.  CERTIFICATES.  Every holder of stock of the corporation
shall be entitled to have a certificate signed by, or in the name of the
corporation by, the Chairman of the Board of Directors, if the Board has
appointed one, or the President or a Vice President, and by the Secretary or an
Assistant Secretary, or the Treasurer or an Assistant Treasurer of the
corporation, certifying the number of shares represented by the certificate
owned by such stockholder in the corporation.

          Section 2.  SIGNATURES ON CERTIFICATES.  Any or all of the signatures
on the certificate may be a facsimile.  In case any officer, transfer agent, or
registrar who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be such officer, transfer agent, or registrar
before such certificate is issued, it may be issued by the corporation with the
same effect as if he were such officer, transfer agent, or registrar at the date
of issue.

          Section 3.  STATEMENT OF STOCK RIGHTS, PREFERENCES, PRIVILEGES.  If
the corporation shall be authorized to issue more than one class of stock or
more than one series of any class, the powers, designations, preferences and
relative, participating, optional or other special rights of each class of stock
or series thereof and the qualification, limitations or restrictions of such
preferences and/or rights shall be set forth in full or summarized on the face
or back of the certificate which the corporation shall issue to represent such
class or series of stock, provided that, except as otherwise provided in Section
202 of the General Corporation Law of Delaware, in lieu of the foregoing
requirements, there may be set forth on the face or back of the certificate
which the corporation shall issue to represent such class or series of stock, a
statement that the corporation will furnish without charge to each stockholder
who so requests the powers, designations, preferences and relative,
participating, optional or other special rights of each class of stock or series
thereof and the qualifications, limitations or restrictions of such preferences
and/or rights.

          Section 4.  LOST CERTIFICATES.  The Board of Directors may direct a
new certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the corporation alleged to have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed.  When
authorizing such issue of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or his legal representative, to advertise the same in such manner
as it shall require and/or to give the corporation a bond in such sum as it may
direct as indemnity against any

                                      11
<PAGE>
 
claim that may be made against the corporation with respect to the certificate
alleged to have been lost, stolen or destroyed.

          Section 5.  TRANSFERS OF STOCK.  Upon surrender to the corporation, or
the transfer agent of the corporation, of a certificate for shares duly endorsed
or accompanied by proper evidence of succession, assignation or authority to
transfer, it shall be the duty of the corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books.

          Section 6.  FIXED RECORD DATE.  In order that the corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
the stockholders, or any adjournment thereof, or entitled to receive payment of
any dividend or other distribution or allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of stock or
for the purpose of any other lawful action, the Board of Directors may fix a
record date which shall not be more than 60 (sixty) nor less than 10 (ten) days
before the date of such meeting, nor more than 60 (sixty) days prior to any
other action.  A determination of stockholders of record entitled to notice of
or to vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board of Directors may fix a new record
date for the adjourned meeting.

          Section 7.  REGISTERED STOCKHOLDERS.  The corporation shall be
entitled to treat the holder of record of any share or shares of stock as the
holder in fact thereof and accordingly shall not be bound to recognize any
equitable or other claim or interest in such share on the part of any other
person, whether or not it shall have express or other notice thereof, save as
expressly provided by the laws of the State of Delaware.

                                  ARTICLE VII

                              GENERAL PROVISIONS
                              ------------------

          Section 1.  DIVIDENDS.  Dividends upon the capital stock of the
corporation, subject to the provisions of the Certificate of Incorporation, if
any, may be declared by the Board of Directors at any regular or special
meeting, pursuant to law.  Dividends may be paid in cash, in property, or in
shares of the capital stock, subject to the provisions of the Certificate of
Incorporation.

          Section 2.  PAYMENT OF DIVIDENDS; DIRECTORS' DUTIES.  Before payment
of any dividend there may be set aside out of any funds of the corporation
available for dividends such sum or sums as the directors from time to time, in
their absolute discretion, think proper as a reserve fund to meet contingencies,
or for equalizing dividends, or for repairing or maintaining any property of the
corporation, or for such other purpose as the directors shall think conducive to
the interests of the corporation, and the directors may abolish any such
reserve.

          Section 3.  CHECKS.  All checks or demands for money and notes of the
corporation shall be signed by such officer or officers as the Board of
Directors may from time to time designate.

                                      12

"Corporate Seal, Delaware."  Said seal may be used by causing it or a facsimile
thereof to be impressed or affixed or reproduced or otherwise.

          Section 6.  MANNER OF GIVING NOTICE.  Whenever, under the provisions
of the statutes or of the Certificate of Incorporation or of these Bylaws,
notice is required to be given to any director or stockholder, it shall not be
construed to mean personal notice, but such notice may be given in writing, by
mail, addressed to such director or stockholder, at his address as it appears on
the records of the corporation, with postage thereon prepaid, and such notice
shall be deemed to be given at the time when the same shall be deposited in the
United States mail.  Notice to directors may also be given by telegram.

          Section 7.  WAIVER OF NOTICE.  Whenever any notice is required to be
given under the provisions of the statutes or of the Certificate of
Incorporation or of these Bylaws, a waiver thereof in writing, signed by the
person or persons entitled to said notice, whether before or after the time
stated therein, shall be deemed equivalent thereto.

          Section 8.  ANNUAL STATEMENT.  The Board of Directors shall present at
each annual meeting, and at any special meeting of the stockholders, a full and
clear statement of the business and condition of the corporation.

                                 ARTICLE VIII

                                  AMENDMENTS
                                  ----------

          Section 1.  AMENDMENT BY DIRECTORS.  These Bylaws may be altered,
amended or repealed or new Bylaws may be adopted by the Board of Directors, when
such power is conferred upon the Board of Directors by the Certificate of
Incorporation, at any regular meeting of the Board of Directors or at any
special meeting of the Board of Directors if notice of such alteration,
amendment, repeal or adoption of new Bylaws be contained in the notice of such
special meeting.  If the power to adopt, amend or repeal Bylaws is conferred
upon the Board of Directors by the Certificate of Incorporation, it shall not
divest or limit the power of the stockholders to adopt, amend or repeal Bylaws.

          Section 2.  AMENDMENT BY STOCKHOLDERS.  These Bylaws may be altered,
amended or repealed or new Bylaws may be adopted by the stockholders, at any
regular meeting of the stockholders or at any special meeting of the
stockholders if notice of such alteration, amendment, repeal or adoption of new
Bylaws be contained in the notice of such special meeting; provided, however,
any proposal to adopt, amend or repeal Bylaws shall require not less than the
affirmative vote of two-thirds of the issued and outstanding stock of the
Corporation entitled to vote thereon.

authorized, validly issued, fully paid, nonassessable and shall not have been
issued in violation of or subject to any preemptive rights. Each Warrant not
exercised prior to the expiration of the Exercise Period shall become void, and
all rights thereunder and all rights in respect thereof under this Agreement
shall cease as of the expiration of the Exercise Period.

     4.2    Exercise of Warrants. During the Exercise Period, each Holder may,
            --------------------

exercised on the date such Warrant Certificate(s) are surrendered to the Warrant
Agent and tender of payment of the Exercise Price is made. Payment of the
aggregate Exercise Price shall be made in cash by wire transfer of immediately
available funds to the Warrant Agent for the account of the Company or by
certified or official bank check or checks to the order of the Company or by any
combination thereof.

Company shall issue and cause to be delivered with all reasonable dispatch, to
or upon the written order of the Holder and in such name or names as the Holder
may designate, a certificate or certificates for the number of full Warrant
Shares issuable upon the exercise of such Warrants and shall take such other
actions at its sole expense as are necessary to complete the exercise of the

Agent shall have no responsibility or liability for such issuance or the
determination of the number of Warrant Shares issuable upon such exercise. The

the Warrants are exercised hereunder. Each Warrant Share, when issued upon
exercise of the Warrants, shall be duly authorized, validly issued, fully paid
and non-assessable and will not have been issued in violation of or subject to
any preemptive rights.

     In the event that less than all of the Warrants evidenced by a Warrant

remaining Warrant or Warrants, and the Warrant Agent is hereby irrevocably
authorized by the Company to countersign, issue and deliver the required new
Warrant Certificate or Certificates evidencing such remaining Warrant or
Warrants pursuant to the provisions of this Section 4.2 hereof and of Section 3
hereof. The Company, whenever required by the Warrant Agent, will supply the
Warrant Agent with Warrant Certificates duly executed on behalf to the Company
for such purpose.

surrendered upon exercise. Such canceled Warrant Certificates shall then be
disposed of by the Warrant Agent in a manner permitted by applicable laws and

Warrant Agent. The Warrant Agent shall account promptly to the Company with
respect to Warrants exercised and concurrently pay to the Company all amounts
received by the Warrant Agent upon exercise of such Warrants.

     The Warrant Agent shall keep copies of this Agreement and any notices given
or received hereunder available for inspection by the Holders during normal
business hours at its office. The Company shall at its sole expense supply the
Warrant Agent from time to time with such numbers of copies of this Agreement as
the Warrant Agent may request.

        --------

the exercise of Warrants, provided, that the Company shall not be

required to pay any tax or taxes which may be payable in respect of any transfer
of the Warrants or involved in the issuance or delivery of any Warrant Shares in
a name other than that of the Holder of the Warrants being exercised, and the
Warrant Agent shall not register any such transfer or issue or deliver any
Warrant Certificate(s) or Warrant Shares unless or until the persons requesting
the registration or issuance shall have paid to the Warrant Agent for the
account of the Company the amount of such tax, if any, or shall have established
to the reasonable satisfaction of the Company that such tax, if any, has been
paid.


SECTION 6.  MUTILATED OR MISSING WARRANT CERTIFICATES. In the event that any
            -----------------------------------------                        
Warrant Certificate shall be mutilated, lost, stolen or destroyed, the Company
shall issue, and at the direction of the Company by written order the Warrant
Agent shall countersign and deliver in exchange and substitution for and upon
cancellation of the mutilated Warrant Certificate or in lieu of and substitution
for the Warrant Certificate lost, stolen or destroyed, a new Warrant Certificate
of like tenor and representing an equivalent right or interest, but only upon
receipt of evidence reasonably satisfactory to the Company and the Warrant Agent
of such loss, theft or destruction of such Warrant Certificate and an indemnity
or bond, if requested by the Company or the Warrant Agent, also reasonably
satisfactory to them. An applicant for such a substitute Warrant Certificate
shall also comply with such other reasonable procedures as the Company or the
Warrant Agent may reasonably require.


SECTION 7.  RESERVATION OF WARRANT SHARES. There have been reserved, and the
            -----------------------------                                    
Company shall at all times keep reserved, out of its authorized Common Stock,
free of all preemptive rights, a number of shares of Common Stock sufficient to
provide for the exercise of the rights of purchase represented by the
outstanding Warrants. The transfer agent for the Common Stock and every
subsequent or other transfer agent for any shares of the Company's capital stock
issuable upon the exercise of the Warrants (each, a "Transfer Agent") will be
                                                     --------------          
and are hereby irrevocably authorized and directed at all times to reserve such
number of authorized shares as shall be required for such purpose. The Company
will keep a copy of this Agreement on file with each Transfer Agent. The Warrant
Agent is hereby irrevocably authorized to requisition from time to time from the
Company or a Transfer Agent, as the case may be, the certificate for Warrant
Shares required to honor outstanding Warrants upon exercise thereof in
accordance with the terms of this Agreement. The Company will supply its
Transfer Agents with duly executed stock certificates for such purposes and will
itself provide or otherwise make available any cash which may be payable as
provided in Section 10 hereof. The Company will furnish to its Transfer Agents a
copy of all notices of adjustments and certificates related thereto, transmitted
to each Holder pursuant to Section 9.3 hereof. The Company will give the Warrant
Agent prompt notice of any change in any Transfer Agent or any change of address
of any Transfer Agent.

     Before taking any action which would cause an adjustment pursuant to
Section 9 reducing the Exercise Price, the Company will take any and all
corporate action which may be necessary in order that the Company may validly
and legally issue fully paid and nonassessable Warrant Shares at the Exercise
Price as so adjusted.


SECTION 8.  STOCK EXCHANGE LISTINGS. The Company shall use its Commercially
            -----------------------                                         
Reasonable Efforts (including requests for waivers) to have the Warrants listed
on the New York Stock Exchange and failing that included for quotation in The
Nasdaq National Market or listed on the American Stock Exchange, and shall use
its Commercially Reasonable Efforts to maintain such listing or inclusion. In
the event the Warrants do not qualify for such listing or inclusion, the Company
will use its Commercially Reasonable Efforts (including, requests for waivers)
to effect such inclusion or listing

                                       6
<PAGE>
 
whenever the Warrants qualify therefor. Any such listing and inclusion shall be
at the Company's sole expense.


SECTION 9.  ADJUSTMENT OF EXERCISE PRICE; NUMBER OF WARRANT SHARES AND SHARES OF
            --------------------------------------------------------------------
CAPITAL STOCK WARRANTS ARE EXERCISABLE INTO. The number and kind of securities
- -------------------------------------------                                    
purchasable upon the exercise of each Warrant, and the Exercise Price, shall be
subject to adjustment from time to time upon the happening of certain events, as
hereinafter described.

     9.1    Mechanical Adjustments. The number of Warrant Shares purchasable
            ----------------------                                      
upon the exercise of each Warrant and the Exercise Price shall be subject to
adjustment as follows:

            (a)  Adjustment for Change in Capital Stock. Subject to paragraphs
                 --------------------------------------                       
(f) and (h) below, in case the Company shall (i) pay a dividend on its
outstanding shares of Common Stock in shares of Common Stock or make a
distribution of shares of Common Stock on its outstanding shares of Common
Stock, (ii) make a distribution on its outstanding shares of Common Stock in
shares of its capital stock other than Common Stock, (iii) subdivide its
outstanding shares of Common Stock into a greater number of shares of Common
Stock, (iv) combine its outstanding shares of Common Stock into a smaller number
of shares of Common Stock, or (v) issue, by reclassification of its shares of
Common Stock, other securities of the Company (including any such
reclassification in connection with a consolidation or merger in which the
Company is the surviving entity), then the number of Warrant Shares purchasable
upon exercise of each Warrant immediately prior thereto shall be adjusted so
that the Holder of each Warrant shall be entitled to receive the kind and number
of Warrant Shares or other securities of the Company which such Holder would
have owned or have been entitled to receive upon the happening of any of the
events described above had such Warrant been exercised in full immediately prior
to the happening of such event or any record date with respect thereto. If a
Holder is entitled to receive shares of two or more classes of capital stock of
the Company pursuant to the foregoing upon exercise of Warrants, the allocation
of the adjusted Exercise Price between such classes of capital stock shall be
determined reasonably and in good faith by the Board of Directors of the
Company. After such allocation, the exercise privilege and the Exercise Price
with respect to each class of capital stock shall thereafter be subject to
adjustment on terms substantially identical to those applicable to Common Stock
in this Section 9. An adjustment made pursuant to this paragraph (a) shall
become effective immediately after the record date for such event or, if none,
immediately after the effective date of such event. Such adjustment shall be
made successively whenever such an event occurs.

            (b)  Adjustment for Rights Issue. Subject to paragraphs (f) and (h)
                 ---------------------------   
below, in case the Company shall issue rights, options or warrants
(collectively, "Rights") to all holders of its outstanding Common Stock
                ------     
entitling them to subscribe for or purchase shares of Common Stock at a Price
Per Share (as defined in paragraph (e) below) which is lower at the record date
mentioned below than the then Current Market Price (as defined in paragraph (e)
below) per share of Common Stock, the number of Warrant Shares thereafter
purchasable upon the exercise of each Warrant shall be determined by multiplying
the number of Warrant Shares theretofore purchasable upon exercise of each
Warrant by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding on the date of issuance of such Rights plus the
additional Number of Shares (as defined in paragraph (e) below) of Common Stock
offered for subscription or purchase in connection with such Rights and the
denominator of which shall be the number of shares of Common Stock outstanding
on the date of issuance of such Rights plus the number of shares which the
aggregate Proceeds (as defined in paragraph (e) below) received or receivable by
the Company upon exercise of such Rights would purchase at the Current Market
Price per share of Common Stock at such record date. Such adjustment

                                       7
<PAGE>
 
shall be made whenever Rights are issued, and shall become effective immediately
after the record date for the determination of stockholders entitled to receive
Rights.

            (c)  Adjustment for Other Distributions. Subject to paragraphs (f)
                 ----------------------------------   
and (h) below, in case the Company shall distribute to all holders of its shares
of Common Stock (x) evidences of indebtedness or assets (excluding cash
dividends or distributions payable out of the consolidated earnings or surplus
legally available for such dividends or distributions and dividends or
distributions referred to in paragraphs (a) or (b) above) of the Company or any
corporation or other legal entity a majority of the voting equity or equity
interests of which are owned, directly or indirectly, by the Company (a
"Subsidiary"), or (y) shares of capital stock of a Subsidiary (such evidences of
 ----------          
indebtedness, assets and securities as set forth in clauses (x) and (y) above,
collectively, "Assets"), then in each case the number of Warrant Shares
               ------    
thereafter purchasable upon the exercise of each Warrant shall be determined by
multiplying the number of Warrant Shares theretofore purchasable upon the
exercise of each Warrant by a fraction, the numerator of which shall be the
Current Market Price per share of Common Stock on the date of such distribution
and the denominator of which shall be such Current Market Price per share of
Common Stock less the fair value as of such record date as determined reasonably
and in good faith by the Board of Directors of the Company of the portion of the
Assets applicable to one share of Common Stock. Such adjustment shall be made
whenever any such distribution is made, and shall become effective on the date
of distribution retroactive to the record date for the determination of
stockholders entitled to receive such distribution.

            (d)  Adjustment for Common Stock and Convertible Securities Issue.  
                 ------------------------------------------------------------ 
Subject to paragraphs (f) and (h) below, in case the Company shall issue shares
of its Common Stock, or securities convertible into, or exchangeable or
exercisable for Common Stock or Rights to subscribe for or purchase such
securities (collectively, "Convertible Securities") (excluding the issuance of
                           ----------------------   
(i) Common Stock or Convertible Securities issued in any of the transactions
described in paragraphs (a), (b) or (c) above or (ii) Warrant Shares issued upon
the exercise of the Warrants, at a Price Per Share of Common Stock, in the case
of the issuance of Common Stock, or at a Price Per Share of Common Stock
initially deliverable upon conversion or exercise of exchange of such
Convertible Securities, in each case, together with any other consideration
received by the Company in connection with such issuance, below the then Current
Market Price per share of Common Stock on the date the Company fixed the
offering, conversion or exercise or exchange price of such additional shares,
then the number of Warrant Shares thereafter purchasable upon the exercise of
each Warrant shall be determined by multiplying the number of Warrant Shares
theretofore purchasable upon exercise of each Warrant by a fraction, the
numerator of which shall be the total number of shares of Common Stock
outstanding on such date plus the additional Number of Shares of Common Stock
offered for subscription or purchase and the denominator of which shall be the
number of shares of Common Stock outstanding on such date plus the number of
shares of Common Stock which the aggregate Proceeds of the total amount of
Convertible Securities so offered would purchase at the Current Market Price Per
Share of Common Stock at such record date. In case the Company shall issue and
sell Convertible Securities for a consideration consisting, in whole or in part,
of property other than cash or its equivalent, then in determining the "Price
Per Share" of Common Stock and the "consideration received by the Company" for
purposes of the first sentence and the immediately preceding sentence of this
paragraph (d), the Board of Directors of the Company shall reasonably and in
good faith determine the fair value of such property. The determination of
whether any adjustment is required under this paragraph (d), by reason of the
sale and issuance of any Convertible Securities and the amount of such
adjustment, if any, shall be made at such time and not at the subsequent time of
issuance of shares of Common Stock upon the exercise, conversion or exchange of
Convertible Securities.

            (e)  Current Market Price; Price Per Share. (i) For the purpose of
                 -------------------------------------              
any computation under Section 4.2 hereof or this Section 9.1, the "Current
                                                                   -------
Market Price" per share of Common Stock at any date shall be the average of the
- ------------  
daily closing prices for the 20 consecutive trading days preceding the date of
such computation. The closing price for each day shall be (x) if the Common
Stock shall be then listed or admitted to trading on the New York Stock
Exchange, the closing price on the NYSE -Consolidated Tape (or any successor
composite tape reporting transactions on the New York Stock Exchange) or, if
such a composite tape shall not be in use or shall not report transactions in
the Common Stock, or if the Common Stock shall be listed on a stock exchange
other than the New York Stock Exchange, the last reported sales price regular
way or, in case no such reported sale takes place on such day, the average of
the closing bid and asked prices regular way for such day, in each case on the
principal national securities exchange on which the shares of Common Stock are
listed or admitted to trading (which shall be the national securities exchange
on which the greatest number of shares of the Common Stock have been traded
during such 20 consecutive trading days) or (y) if the Common Stock is not
listed or admitted to trading, the average of the closing bid and asked prices
of the Common Stock in the over-the-counter market as reported by The Nasdaq
National Market or any comparable system or, if the Common Stock is not included
for quotation in The Nasdaq National Market or a comparable system, the average
of the closing bid and asked prices as furnished by two members of the NASD
selected reasonably and in good faith from time to time by the Board of
Directors for that purpose. In the absence of one or more such quotations, the
Current Market Price per share of the Common Stock shall be determined
reasonably and in good faith by the Board of Directors of the Company.

           (ii)  For purposes of this Section 9.1, "Price Per Share" shall be 
                                                    ---------------  
defined and determined according to the following formula:

                 P  = R/N

                 where

                 P  = Price Per Share;

                 R  = the "Proceeds" received or receivable by the Company which
                      (x) in the case of shares of Common Stock is the total
                      amount received or receivable by the Company in
                      consideration for the issuance and sale of such shares;
                      (y) in the case of Rights or of Convertible Securities
                      with respect to shares of Common Stock, is the total
                      amount received or receivable by the Company in
                      consideration for the issuance and sale of Rights or such
                      Convertible Securities, plus the minimum aggregate amount
                      of additional consideration, other than the surrender of
                      such Convertible Securities, payable to the Company upon
                      exercise, conversion or exchange thereof; and (z) in the
                      case of Rights to subscribe for or purchase such
                      Convertible Securities, is the total amount received or
                      receivable by the Company in consideration for the
                      issuance and sale of such Rights plus the minimum
                      aggregate amount of additional consideration, other than
                      the surrender of such Convertible Securities, payable upon
                      the conversion or exchange or exercise of such Convertible
                      Securities, provided that in each case the proceeds

                      received or receivable by the Company shall be the net

                      sale, underwriting or purchase thereof by underwriters or
                      dealers or others performing similar services; and

                 N  = the "Number of Shares," which (x) in the case of Common
                      Stock is the number of shares issued; and (y) in the case
                      of Rights or of Convertible Securities with respect to
                      shares of Common Stock, is the maximum number of shares of
                      Common Stock initially issuable upon exercise, conversion
                      or exchange thereof.

            (f)  When De Minimis Adjustment May Be Deferred. No adjustment in
                 ------------------------------------------          
the number of Warrant Shares purchasable hereunder shall be required unless such
adjustment would require an increase or decrease of at least one percent (1%) in
the number of Warrant Shares purchasable upon the exercise of each Warrant,
provided that any adjustments which by reason of this paragraph (f) are not
- --------                                                                   
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations shall be made to the nearest one-
thousandth of a Warrant Share and the nearest cent.

            (g)  Adjustment in Exercise Price. Whenever the number of Warrant
                 ----------------------------                                 
Shares purchasable upon the exercise of each Warrant is adjusted as herein
provided, the Exercise Price payable upon exercise of each Warrant immediately
prior to such adjustment shall be adjusted by multiplying such Exercise Price by
a fraction, the numerator of which shall be the number of Warrant Shares
purchasable upon the exercise of each Warrant immediately prior to such
adjustment and the denominator of which shall be the number of Warrant Shares
purchasable immediately thereafter.

            (h)  When No Adjustment Required. No adjustment in the number of
                 ---------------------------                                 
Warrant Shares purchasable upon the exercise of each Warrant need be made under
this Section 9.1 in connection with: (i) the issuance of Common Stock, options,
rights, warrants or other securities pursuant to the Plan; (ii) shares of Common
Stock, options, rights, warrants or other securities issued pursuant to any plan
adopted by the Company or its subsidiaries for the benefit of employees or
directors; (iii) shares of Common Stock, options, rights, warrants or other
securities issued pursuant to any share purchase rights plan adopted by the
Company; (iv) any issuance of shares of Common Stock or securities convertible
into or exchangeable for shares of Common Stock pursuant to an underwritten
public offering for a price per share of Common Stock in the case of an issuance
of shares of Common Stock, or for a price per share of Common Stock initially
deliverable upon conversion or exchange of such securities, that is equal to or
greater than 95% of the Current Market Price per share of Common Stock on the
date the Company fixed the offering, conversion or exchange price of such
additional shares of Common Stock; (v) sales of Common Stock pursuant to a plan
adopted by the Company for reinvestment of dividends or interest; or (vi) shares
of Common Stock issued to shareholders of any corporation that is acquired by,
merged into or made a part or subsidiary of the Company in an arm's-length
transaction. Additionally, no adjustment need be made if the Company issues or
distributes to each Holder of Warrants the shares, rights, options, warrants,
evidences of indebtedness, assets or other securities referred to in those
paragraphs which each Holder of Warrants would have been entitled to receive had
the Warrants been exercised for the number of Warrant Shares for which Warrants
are then exercisable prior to the happening of such event or the record date
with respect thereto. No adjustment in the number of Warrant Shares will be made
for a change in the par value of the shares of Common Stock.

            (i)  Shares of Common Stock. For all purposes of this Agreement,
                 ----------------------                                 
the term "shares of Common Stock" shall mean (i) the class of stock designated
as the Common Stock of the Company at the date of this Agreement or (ii) any
other class of stock resulting from successive changes or reclassification of
such shares consisting solely of changes in par value, or from par value to no
par

                                      10
<PAGE>
 
value, or from no par value to par value. In the event that at any time, as a
result of an adjustment made pursuant to this Section 9.1, the Holders shall
become entitled to purchase any securities of the Company other than shares of
Common Stock, thereafter the number of such other shares so purchasable upon
exercise of each Warrant and the Exercise Price of such shares shall be subject
to adjustment from time to time in a manner and on terms substantially identical
to the provisions with respect to the Warrant Shares contained in paragraphs (a)
through (h) above, and the provisions of this Agreement with respect to the
Warrant Shares shall apply on like terms to any such other securities.

            (j)  Expiration of Rights, etc. Upon the expiration of any Rights
                 -------------------------                                
or conversion or exchange or exercise rights, if any thereof shall not have been
exercised, the Exercise Price and the number of Warrant Shares purchasable upon
the exercise of each Warrant shall, upon such expiration, be readjusted and
shall thereafter be such as it would have been had it been originally adjusted
(or had the original adjustment not been required, as the case may be) as if (A)
the only shares of Common Stock so issued were the shares of Common Stock, if
any, actually issued or sold upon the exercise of such Rights or conversion or
exchange or exercise rights and (B) such shares of Common Stock, if any, were
issued or sold for the consideration actually received by the Company upon such
exercise plus the aggregate consideration, if any, actually received by the
Company for the issuance, sale or grant of all of such Rights or conversion or
exchange or exercise rights whether or not exercised, provided that no such
                                                      --------             
readjustment shall have the effect of increasing the Exercise Price or
decreasing the number of Warrant Shares purchasable upon the exercise of each
Warrant by an amount in excess of the amount of the adjustment initially made in
respect of the issuance, sale or grant of such Rights or conversion or exchange
or exercise rights.

     9.2    Voluntary Adjustment by the Company. The Company may at its option,
            -----------------------------------                                 
at any time during the term of the Warrants, reduce the then current Exercise
Price to any amount deemed appropriate by the Board of Directors of the Company.

     9.3    Notice of Adjustment. Whenever the number of Warrant Shares
            --------------------                                        
purchasable upon the exercise of each Warrant or the Exercise Price of Warrant
Shares is adjusted, as herein provided, the Company shall cause the Warrant
Agent promptly to mail to each Holder, at the sole expense of the Company by
first class mail, postage prepaid, notice of such adjustment or adjustments and
shall deliver to the Warrant Agent a certificate of a firm of independent public
accounts (who may be the regular accountants employed by the Company) setting
forth the number of Warrant Shares purchasable upon the exercise of each Warrant
and the Exercise Price of Warrant Shares after such adjustment, setting forth a
brief statement of the facts requiring such adjustment and setting forth in
reasonable detail the computations by which such adjustment was made. The
Warrant Agent shall be entitled to rely on such certificate and shall be under
no duty or responsibility with respect to any such certificate, except to
exhibit the same, from time to time, to any Holder requesting an inspection
thereof during reasonable business hours. The Warrant Agent shall not at any
time be under any duty or responsibility to any Holder to determine whether any
facts exist which may require any adjustment of the Exercise Price or the number
of Warrant Shares or other stock or property purchasable on exercise of
Warrants, or with respect to the nature or extent of any such adjustment when
made, or with respect to the method employed in making such adjustment.

     9.4    Preservation of Purchase Rights upon Merger or Consolidation. In
            ------------------------------------------------------------   
case of any consolidation of the Company with or merger of the Company into
another entity, the Company or such successor entity shall execute and deliver
to the Warrant Agent an agreement, which shall be binding on the Holders, that
each Holder shall have the right thereafter upon payment of the Exercise Price
in effect immediately prior to such action (after giving effect to any
Applicable Adjustments under Section 9.1 hereof) to purchase upon exercise of
each Warrant the kind and amount of shares and other

                                      11
<PAGE>
 
securities and property (including cash) which such Holder would have owned or
have been entitled to receive after the happening of such consolidation or
merger had such Warrant been exercised immediately prior to such action. The
Company shall at its sole expense mail by first class mail, postage prepaid, to
each Holder notice of the execution of any such agreement. Such agreement shall
provide for adjustments, which shall be substantially identical to the
adjustments provided for in this Section 9. In addition, the Company shall not
merge or consolidate with or into, any other entity unless the successor entity
(if not the Company), shall expressly assume, by supplemental agreement
reasonably satisfactory in form and substance to the Warrant Agent in its sole
judgment and executed and delivered to the Warrant Agent, the due and punctual
performance and observance of each and every covenant and condition of this
Agreement to be performed and observed by the Company. The provisions of this
Section 9.4 shall similarly apply to successive consolidations or mergers. The
Warrant Agent shall be under a good faith duty and responsibility to determine
the correctness of any provisions contained in any such agreement relating to
the kind or amount of shares of stock or other securities or property receivable
upon exercise of Warrants or with respect to the method employed and provided
therein for any adjustments and shall be entitled to rely upon the provisions
contained in any such agreement.

     9.5    Statement on Warrants. Irrespective of any adjustments in the
            ---------------------                                         
Exercise Price or the number or kind of shares purchasable upon the exercise of
the Warrants, Warrants theretofore or thereafter issued may continue to express
the same Exercise Price and number and kind of Warrant Shares as are stated in
the Warrants initially issuable pursuant to this Agreement.


SECTION 10.  FRACTIONAL INTERESTS. Neither the Company nor the Warrant Agent
             --------------------                                            
shall be required to issue fractional Warrant Shares on the exercise of
Warrants. If more than one Warrant shall be exercised at the same time by the
same Holder, the number of full Warrant Shares which shall be issuable upon such
exercise shall be computed on the basis of the aggregate number of Warrants so
exercised. If any fraction of a Warrant Share would, except for the provisions
of this Section 10, be issuable on the exercise of any Warrant, the Company
shall pay an amount in cash equal to the closing price for one share of Common
Stock on the date the Warrant Certificate is presented for exercise (determined
in accordance with the second sentence of Section 9.1(e)(i) hereof), multiplied
by such fraction.


SECTION 11.  NO RIGHTS AS STOCKHOLDERS; NOTICES TO HOLDERS. Nothing contained
             ---------------------------------------------                    
in this Agreement or in any of the Warrants shall be construed as conferring
upon the Holders or their transferees the right to vote or to receive dividends
or to consent or to receive notice as stockholders in respect of any meeting of
stockholders for the election of directors of the Company or any other matter,
or any rights whatsoever as stockholders of the Company.

            In case:

            (a)  the Company shall authorize the issuance to all holders of
     shares of Common Stock of rights, options or warrants to subscribe for or
     purchase shares of Common Stock or of any other subscription rights or
     warrants; or

            (b)  the Company shall authorize the distribution to all holders of
     shares of Common Stock of securities or assets (other than cash dividends);
     or

                                      12
<PAGE>
 
            (c)  of any consolidation or merger to which the Company is a party
     and for which approval of any stockholders of the Company is required, or
     of the conveyance or transfer of a substantial portion of the properties
     and assets of the Company for which approval of any stockholders of the
     Company is required, or of any reclassification or change of Common Stock
     issuable upon exercise of the Warrants (other than a change in par value,
     or from par value to no par value, or from no par value to par value, or as
     a result of a subdivision or combination), or a tender offer or exchange
     offer for shares of Common Stock; or

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

then the Company shall cause to be filed with the Warrant Agent and shall cause
to be given to each Holder at its address appearing on the Warrant Register, at
least twenty (20) days prior to the applicable record date hereinafter
specified, or promptly in the case of events for which there is no record date,
by first class mail, postage prepaid, a written notice stating (i) the date as
of which the holders of record of shares of Common Stock entitled to receive any
such rights, options, warrants or distribution are to be determined, or (ii) the
initial expiration date set forth in any tender offer or exchange offer for
shares of Common Stock, or (iii) the date on which any such reclassification,
consolidation, merger, conveyance, transfer, dissolution, liquidation or winding
up is expected to become effective or consummated, as well as the date as of
which it is expected that holders of record of shares of Common Stock shall be
entitled to exchange such shares for securities or other property, if any,
deliverable upon such reclassification, consolidation, merger, conveyance,
transfer, dissolution, liquidation, or winding up. The failure to give the
notice required by this Section 11 or any defect therein shall not affect the
legality or validity of any distribution, right, option, warrant,
reclassification, consolidation, merger, conveyance, transfer, dissolution,
liquidation, winding up or action, or the vote upon any of the foregoing.


SECTION 12.  PAYMENTS IN U.S. CURRENCY. All payments required to be made
             -------------------------                                   
hereunder shall be made in lawful money of the United States of America.


SECTION 13.  MERGER OR CONSOLIDATION OR CHANGE OF NAME OF WARRANT AGENT. Any
             ----------------------------------------------------------      
corporation into which the Warrant Agent may be merged or with which it may be
consolidated, or any corporation resulting from any merger or consolidation to
which the Warrant Agent shall be a party, or any corporation succeeding to the
corporation trust business of the Warrant Agent, shall be the successor to the
Warrant Agent hereunder without the execution or filing of any paper or any
further act on the part of any of the parties hereto, provided that such
corporation would be eligible for appointment as a successor Warrant Agent under
the provisions of Section 15 hereof. In case at the time such successor to the
Warrant Agent shall succeed to the agency created by this Agreement, any of the
Warrant Certificates shall have been countersigned but not delivered, any such
successor to the Warrant Agent may adopt the countersignature of the original
Warrant Agent and deliver such Warrant Certificates so countersigned; and in
case at that time any of the Warrant Certificates shall not have been
countersigned, any successor to the Warrant Agent may countersign such Warrant
Certificates either in the name of the predecessor Warrant Agent or in the name
of the successor Warrant Agent; and in all such cases such Warrant Certificates
shall be fully valid and effective as provided therein and in this Agreement.

     In case at any time the name of the Warrant Agent shall be changed and at
such time any of the Warrant Certificates shall have been countersigned but not
delivered, the Warrant Agent may adopt

                                      13
<PAGE>
 
the countersignatures under its prior name and deliver such Warrant Certificates
so countersigned; and in case at that time any of the Warrant Certificates shall
not have been countersigned, the Warrant Agent may countersign such Warrant
Certificates either in its prior name or in its changed name; and in all such
cases such Warrant Certificates shall be fully valid and effective as provided
therein and in this Agreement.


SECTION 14.  APPOINTMENT OF WARRANT AGENT. The Company hereby appoints the
             ----------------------------

any failure of the Company to comply with any of the covenants contained in this
Agreement or in the Warrant to be complied with by the Company.

     14.4   Performance of Duties. The Warrant Agent may execute and exercise
            ---------------------

            -------------------                                                 
legal counsel satisfactory to it (who may be counsel for the Company), and the

any Holder in respect to any action taken, suffered or omitted by it hereunder
in good faith and in accordance with the opinion or the advice of such counsel.

     14.6   Proof of Actions Taken. Whenever in the performance of its duties
            ----------------------                                            
under this Agreement the Warrant Agent shall deem it necessary or desirable that
any fact or matter be proved or established by the Company prior to taking or
suffering any action hereunder, such fact or matter (unless other evidence in
respect thereof be herein specifically prescribed) may be deemed conclusively to
be proved and established by a certificate signed by the Chairman of the Board,
the President, a Vice President, the Treasurer or the Secretary of the Company
and delivered to the Warrant Agent; and such certificate shall be full
authorization to the Warrant Agent for any action taken or suffered in good
faith by it under the provisions of this Agreement in reliance upon such
certificate.

     14.7   Compensation. The Company agrees to pay the Warrant Agent
            ------------

performance of its duties under this Agreement, except as a result of the
Warrant Agent's gross negligence or willful misconduct as determined in a final

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

likely to involve expense unless the Company or any one or more Holders shall
furnish the Warrant Agent with reasonable security and indemnity for any costs
and expenses which may be incurred or any liabilities which may arise, but this
provision shall not affect the power of the Warrant Agent to take such action as
the Warrant Agent may consider proper, whether with or without any such security
or indemnity. All rights of action of any Holder under this Agreement or under
any of the Warrants may be enforced by the Warrant Agent without the possession
of any of the Warrant Certificates or the production thereof at any trial or
other proceeding relative thereto, and any such action, suit or proceeding
instituted by the Warrant Agent shall be brought in its name as Warrant Agent,
and any recovery of judgment shall be for the ratable benefit of the Holders, as
their respective rights or interests may appear.

interested or contract with or lend money to the Company or other wise act as

solely as agent, and its duties shall be determined solely by the provisions
hereof. The Warrant Agent shall not be liable for anything which it may do or
refrain from doing in connection with this Agreement except for its own
negligence or bad faith.

     14.11  Reliance on Documents. The Warrant Agent will not incur any
            ---------------------                                       
lability or responsibility to the Company or to any Holder for any action taken
in reliance on any notice, resolution, waiver, consent, order, certificate, or
other paper, document or instrument reasonably believed by it to be genuine and
to have been signed, sent or presented by the proper party or parties.

     14.12  Validity of Agreement. The Warrant Agent shall not be under any
            ---------------------                                           
responsibility in respect of the validity of this Agreement or the execution and
delivery hereof (except the due execution hereof by the Warrant Agent) or in

and directed to accept instructions with respect to the performance of its
duties hereunder from the Chairman of the Board, the President, a Vice
President, the Treasurer or the Secretary of the Company, and to apply to

discharged from its duties under this Agreement by giving to the Company thirty
(30) days' notice in writing. The Warrant Agent may be removed by like notice to
the Warrant Agent and the Holders from the Company, such notice to specify the

successor to the Warrant Agent. Any successor Warrant Agent, whether appointed
by the Company or such a court, shall be a bank or trust Company, in good

vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Warrant Agent with out further act or deed; but the
former Warrant Agent shall deliver and transfer to the successor Warrant Agent
any property at the time held by it hereunder, and shall execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Failure to
file any notice provided for in this Section 15, however, or any defect therein,
shall not affect the legality or validity of the resignation or removal of the
Warrant Agent or the appointment of the successor Warrant Agent, as the case may
be. In the event of such resignation or removal, the successor Warrant Agent
shall mail, by first class mail, postage prepaid, to each Holder, written notice
of such removal or resignation and the name and address of such successor
Warrant Agent.

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

affected thereby.

SECTION 2.     REGISTRATION UNDER THE SECURITIES ACT

          2.1  DEMAND REGISTRATION

               (a)  DEMAND FOR REGISTRATION.  As soon as practicable following
the Company's receipt of a Notice of Demand from Holders holding at least
5,000,000 shares of the Registrable Securities (subject to appropriate
adjustments in the case of stock splits), the Company shall prepare and file a
Registration Statement covering the Registrable Securities that the Company has
been requested to register (whether pursuant to the Notice of Demand or pursuant
to notice provided under Section 2.1(c) hereof) and shall use Commercially
Reasonable Efforts to cause the Registration Statement to become effective
within one hundred eighty (180) days of its receipt of such Notice of Demand.
The Holders are entitled to a maximum of two Demand Registrations under this
Section 2.1 during the term of this Agreement; provided,

                                       5
<PAGE>
 
however, that the Holders may not make a second demand for registration until
twelve (12) months after the date on which the Registration Statement filed
pursuant to the first demand for registration shall have been declared
effective; and provided further, however, that the Holders may not make a second
demand for registration if the average daily trading volume of the Company's
Common Stock on the securities exchange on which the Common Stock is then listed
shall have been one hundred thousand (100,000) shares per day for any
consecutive twenty (20) business day period preceding such second demand.

               (b)  LIMITATIONS ON DEMAND REGISTRATION.  In the event that the
Requesting Holders determine for any reason (other than at the request or
recommendation of the Company or the underwriter or due to the occurrence of a
Material Adverse Change) not to proceed with a registration of Common Stock
requested pursuant to this Section 2.1 at any time before the Registration
Statement has been declared effective by the SEC, and such Registration
Statement, if theretofore filed with the SEC, is withdrawn with respect to the
Common Stock covered thereby, and such Holders reimburse the Company for all
fees, costs and expenses in connection therewith, then the Holders shall not be
deemed to have exercised their right to a Demand Registration pursuant to this
Section 2.1 with respect to such withdrawn Registration Statement. If the
Holders determine not to proceed with such a registration upon the request or
recommendation of the Company or the underwriter or due to the occurrence of a
Material Adverse Change, the Holders will not be required to reimburse the
Company for its fees, costs and expenses and the Holders shall not be deemed to
have exercised their right to a Demand Registration pursuant to this Section 2.1
with respect to such registration.

               (c)  NOTICE TO HOLDERS.  Upon receipt of any Notice of Demand,
the Company will give prompt notice (but in any event within fifteen (15) days
after such receipt) to all Holders of Registrable Securities at the address
provided to the Company in Schedule 1 or as otherwise furnished in writing to
the Company for purposes of this Agreement (the "Registered Address") of the
Notice of Demand and of the Holders' rights under this Section 2.1. Upon the
written request of any such Holder made within twenty (20) days after the
receipt by that Holder of the notice (which request shall specify the
Registrable Securities intended to be disposed of by such Holder and the
intended method or methods of disposition thereof) the Company shall use
Commercially Reasonable Efforts to effect the registration under the Securities
Act of all Registrable Securities which the Company has been so requested to
register by the Holders thereof, to the extent required to permit the
disposition (in accordance with the intended method or methods thereof as
aforesaid) of the Registrable Securities so to be registered.

                                       6
<PAGE>
 
               (d)  CONTINUOUS EFFECTIVENESS OF REGISTRATION STATEMENTS.  Once a
Registration Statement is effective pursuant to Section 2.1(a) hereof, the
Company shall use Commercially Reasonable Efforts to cause such Registration
Statement to remain continuously effective (i) in the case of a Registration
Statement other than a Shelf Registration Statement, until the earlier of (x)
the two (2) month anniversary of the date such Registration Statement is
declared effective by the SEC and (y) the date on which all of the Registrable
Securities covered by such Registration Statement have been sold; and (ii) in
the case of a Shelf Registration Statement, until the earlier of (x) six (6)
months following the date such Shelf Registration Statement is declared
effective by the SEC and (y) the date on which all of the Registrable Securities
covered by such Shelf Registration Statement have been sold, but in no event (in
either case) prior to the expiration of the applicable period referred to in
Section 4(3) of the Securities Act and Rule 174 thereunder (such period being
defined as the "Effective Period" with respect to any such Registration
Statement other than a Shelf Registration Statement and as the "Shelf Period"
with respect to any such Shelf Registration Statement); provided, however, that
(x) with respect to any Registration Statement the Company may suspend use of
such Registration Statement at any time if the continued effectiveness thereof
would require the Company to disclose a material financing, acquisition or other
corporate transaction, which disclosure the Company shall have determined in
good faith is not in the best interests of the Company and its stockholders
(provided the Effective Period or Shelf Period, as the case may be, shall be
extended by the number of days of any such suspension) and (y) with respect to
any Registration Statement the Company may suspend use of any such Registration
Statement during any period if each of the Company and the Requisite Holders of
the Registrable Securities covered by such Registration Statement consents in
writing to such suspension for such period.

               (e)  PRIORITY IN DEMAND REGISTRATIONS.  If a registration
pursuant to this Section 2.1 involves an underwritten offering and the managing
underwriter of such underwritten offering advises the Company in writing (with a
copy to each Participating Holder) of its belief that the amount of securities
requested to be included in such registration exceeds the amount which can be
sold in (or during the time of) such offering within an acceptable price range,
then the amount of securities to be sold in such offering shall be reduced in
accordance with the advice of such managing underwriter. In the case of any such
reduction, then the Company shall include in such Demand Registration that
amount of Registrable Securities that the Company is so advised can be sold in
(or during the time of) the offering, as follows: first, Registrable Securities
of any Participating Holder that is an "underwriter" or and "affiliate" of the
Company in an amount sufficient to include all the shares of Registrable
Securities offered by such Participating Holder or an amount sufficient to
reduce the amount of such Participating Holder's Registrable Securities held
after the offering to a level that would cause such Participating Holder to no
longer be an "underwriter" or an "affiliate" of the Company, whichever amount is
less; second, such Registrable Securities

                                       7
<PAGE>
 
requested to be included in such Registration Statement by any other
Participating Holder, pro rata on the basis of the amount of such securities
held by such other holder; and third, all other securities of the Company duly
requested to be included in such Registration Statement.

          2.2  PIGGYBACK REGISTRATION

               (a)  RIGHT TO INCLUDE REGISTRABLE SECURITIES.  If the Company at
any time proposes to register any of its equity securities under the Securities
Act (other than by a registration on Form S-4 or Form S-8 or any successor or
similar form then in effect and other than pursuant to Section 2.1 hereof) in a
form and in a manner that would permit registration of the Registrable
Securities, whether or not for sale for its own account, it will give prompt
(but in no event less than 30 days prior to the proposed date of filing the
registration statement relating to such registration) notice to all Holders of
Registrable Securities of the Company's intention to do so and of such Holders'
rights under this Section 2.2. Upon the written request of any such Holder made
within twenty (20) days after the receipt by that Holder of the notice (which
request shall specify the Registrable Securities intended to be disposed of by
such Holder and the intended method or methods of disposition thereof), the
Company shall use Commercially Reasonable Efforts to effect the registration
under the Securities Act of all Registrable Securities which the Company has
been so requested to register by the Holders thereof, to the extent required to
permit the disposition (in accordance with the intended method or methods
thereof as aforesaid) of the Registrable Securities so to be registered,
provided that if, at any time after giving notice of its intention to register
any equity securities and prior to the effective date of the registration
statement filed in connection with such registration, the Company determines for
any reason not to register or to delay registration of the equity securities,
the Company may, at its election, give notice of that determination to each such
Holder and, thereupon, (i) in the case of a determination not to register, shall
be relieved of its obligation to register any Registrable Securities in
connection with such registration (but not from its obligation to pay all
Registration Expenses in connection therewith as provided in Section 2.3(b)
hereof), without prejudice, however, to the right of the Holders to request that
such registration be effected as a Demand Registration in accordance with
Section 2.1 hereof, and (ii) in the case of a determination to delay
registering, shall be permitted to delay registering any Registrable Securities
for the same period as the delay in registering such other equity securities. No
registration effected under this Section 2.2 will be deemed to have been
effected pursuant to Section 2.1 hereof (except for any right to a Demand
Registration which may be exercised pursuant to the last clause of subsection
(i) of the preceding sentence) or will relieve the Company of its obligation to
effect a Demand Registration in accordance with Section 2.1. hereof.

                                       8
<PAGE>
 
               (b)  PRIORITY IN PIGGYBACK REGISTRATIONS.  If a registration
pursuant to this Section 2.2 involves an underwritten offering and the managing
underwriter of such underwritten offering advises the Company in writing (with a
copy to each Participating Holder) of its belief that the amount of securities
requested to be included in such registration exceeds the amount which can be
sold in (or during the time of) such offering within an acceptable price range,
then the Company will include in such registration that amount of securities
which the Company is so advised can be sold in (or during the time of) the
offering as follows: first, all securities proposed by the Company to be sold
for its own account; second, Registrable Securities of any Participating Holder
that has properly requested that its Registrable Securities be included in such
registration and that is an "underwriter" or an "affiliate" of the Company in an
amount sufficient to include all the Registrable Securities offered by such
Participating Holder or an amount sufficient to reduce the amount of such
Participating Holder's Registrable Securities held after the offering to a level
that would cause such Participating Holder to no longer be an "underwriter" or
an "affiliate" of the Company, whichever amount is less; third, such Registrable
Securities requested to be included in such registration statement by any other
Participating Holder, pro rata on the basis of the amount of such securities
held by such other Participating Holder; and "fourth", all other securities of
the Company duly requested to be included in such registration statement.

          2.3  REGISTRATION TERMS AND PROCEDURES

               (a)  REGISTRATION STATEMENT FORM.  Registrations under Section
2.1 hereof shall be on Form S-1 or Form S-3 (if use of such a form is then
available to cover resales of the Registrable Securities) or such other
appropriate form of the SEC as shall permit the sale, resale or other
disposition of such Registrable Securities in accordance with the intended
method or methods of disposition.

               (b)  REGISTRATION EXPENSES.  Subject to Section 2.3(f) hereof,
the Company will pay all Registration Expenses incurred in connection with a
registration to be effected (whether or not effected or deemed effected pursuant
to subsection (c) below) pursuant to Sections 2.1 hereof or 2.2 hereof.

               (c)  EFFECTIVENESS OF CERTAIN DEMAND REGISTRATIONS.  A Demand
Registration will not be deemed to have been effected under Section 2.1 hereof
unless the Registration Statement with respect thereto has been declared
effective by the SEC and, subject to Section 2.3(g)(ii) hereof, (i) in the case
of a Registration Statement other than a Shelf Registration Statement, such
Registration Statement remains effective until the earlier of (x) forty-five
(45) days of the date such Registration Statement is declared effective by the
SEC and (y) the date on which all of the Registrable Securities covered by such
Registration Statement have been sold; and (ii) in the case of a Shelf

                                       9
<PAGE>
 
Registration Statement, such Shelf Registration Statement remains effective
until the earlier of six (6) months from its effective date (subject to
extension as contemplated by Section 2.1(d) and the last sentence of Section
2.3(h)(ii) hereof) or the date on which all of the Registrable Securities
covered by such Shelf Registration Statement have been sold; provided, however,
in either case, that if (x) after such registration statement has been declared
effective, the marketing of Registrable Securities offered pursuant to such
registration statement is materially disrupted or adversely affected as a result
of any stop order, injunction or other order or requirement of the SEC or any
other governmental agency or court (for reasons other than a misrepresentation
or omission by any Requesting Holder or any Participating Holder) or (y) the
conditions to closing specified in the purchase agreement or underwriting
agreement entered into in connection with such registration have not been
satisfied (for reasons other than a wrongful or bad faith act, omission or
misrepresentation by any Requesting Holder or any Participating Holder), such
registration statement will be deemed not to have become effective.  If a
registration pursuant to Section 2.1 hereof is deemed not to have been effected
hereunder, then the Company shall continue to be obligated to effect the
remaining number of unused Demand Registrations in accordance with Section 2.1
hereof.

               (d)  SELECTION OF UNDERWRITER.  If, in connection with a
registration effected pursuant to Section 2.1 hereof, the Requisite Holders so
elect, the offering of Registrable Securities pursuant to Section 2.1 hereof
shall be in the form of an underwritten offering. If the Requisite Holders so
elect, they shall select one or more nationally recognized firms of investment
bankers to act as the book-running managing underwriter or underwriters in
connection with such offering, provided that such selection shall be subject to
the consent of the Company, which consent shall not be unreasonably withheld.

               (e)  LIMITATION ON SHELF REGISTRATION STATEMENTS.  
Notwithstanding the provisions of Section 2.1 hereof, only those Participating
Holders who are deemed to be "underwriters" or "affiliates" of the Company for
purposes of the Securities Act shall be permitted to demand the registration of
Registrable Securities pursuant to a Shelf Registration Statement.

               (f)  WITHDRAWAL.  Any Holder participating in a registration
pursuant to this Agreement shall be permitted to withdraw all or part of its
Registrable Securities from such registration at any time prior to the effective
date of the registration statement covering such securities; provided that, in
the event of a withdrawal from a registration effected pursuant to Section 2.1
hereof, such registration shall be deemed to have been effected for purposes of
the first sentence of Section 2.1(b) hereof except as otherwise provided in
Section 2.1(b) hereof.

               (g)  REGISTRATION PROCEDURES.  In connection with the Company's
obligations to register Registrable Securities pursuant to this Agreement, the
Company will use Commercially Reasonable Efforts to effect such registration so
as to permit the sale, resale or other disposition of any Registrable Securities
included in such registration in accordance with the intended method or methods
of distribution thereof, and pursuant thereto the Company will as expeditiously
as possible:

                    (i)     prepare and (as soon thereafter as practicable) file
with the SEC the requisite registration statement containing all information
required thereby to effect such registration and thereafter use Commercially
Reasonable Efforts to cause such registration statement to become and remain
effective in accordance with the terms of this Agreement, provided that as far
in advance as practicable before filing such registration statement or any
amendment, supplement or exhibit thereto (but, with respect to the filing of
such registration statement, in no event later than seven (7) days prior to such
filing), the Company will furnish to the Participating Holders or their counsel
copies of reasonably complete drafts of all such documents proposed to be filed
(excluding exhibits, which shall be made available upon request by any
Participating Holder), and any such Holder shall have the opportunity to object
to any information contained therein and the Company will make the corrections
reasonably requested by such Holder, in writing, with respect to information
relating to such Holder or the plan of distribution of the Registrable
Securities prior to filing any such registration statement, amendment,
supplement or exhibit;

                    (ii)    prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith (A) as reasonably requested by any Participating Holder, in writing,
to which such registration statement relates (but only to the extent such
request relates to information with respect to such Holder) and (B) as may be
necessary to keep such registration statement effective (x) during the Effective
Period in the case of a Registration Statement other than a Shelf Registration
Statement and (y) during the Shelf Period in the case of a Shelf Registration
Statement, and comply with the provisions of the Securities Act with respect to
the sale, resale or other disposition of all securities covered by such
registration statement during such period in accordance with the intended method
or methods of disposition by the seller or sellers thereof set forth in such
registration statement;

                    (iii)   furnish to each Holder covered by, and each
underwriter or agent participating in the disposition of securities under, such
registration statement such number of conformed copies of such registration
statement and of each such amendment and supplement thereto (in each case
excluding all exhibits and documents incorporated by reference, which exhibits
and documents shall be furnished to any such Person upon request), such number
of copies of the prospectus contained in such

                                      11
<PAGE>
 
registration statement (including each preliminary prospectus and any summary
prospectus) and any other prospectus filed under Rule 424 under the Securities
Act relating to such Holder's Registrable Securities, in conformity with the
requirements of the Securities Act, and such other documents as such Holder,
underwriter or agent may reasonably request to facilitate the disposition of
such Registrable Securities;

                    (iv)    use Commercially Reasonable Efforts to register or
qualify all Registrable Securities and other securities covered by such
registration statement under all applicable blue sky and other securities laws,
and to keep such registration or qualification in effect for so long as such
registration statement remains in effect, and take any other action which may be
reasonably necessary or advisable to enable such Holder to consummate the
disposition of the securities owned by such Holder, except that the Company
shall not for any such purpose be required to (A) qualify generally to do
business as a foreign corporation in any jurisdiction wherein it would not but
for the requirements of this clause (iv) be obligated to be so qualified, (B)
subject itself to taxation in any such jurisdiction or (C) consent to general
service of process in any jurisdiction;

                    (v)     use Commercially Reasonable Efforts to cause all
Registrable Securities covered by such registration statement to be registered
with or approved by such other governmental agencies or authorities applicable
to the Company as may be reasonably necessary to enable the seller or sellers
thereof (or underwriter or agent, if any) to consummate the disposition of such
Registrable Securities in accordance with the plan of distribution set forth in
such registration statement;

                    (vi)    promptly notify each Participating Holder at its
Registered Address and any underwriter or agent participating in the disposition
of Registrable Securities covered by such registration statement, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, upon discovery that, or upon the happening of any event known to
the Company 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 any material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances under
which they were made, and promptly prepare and furnish to such Holder (or
underwriter or agent, if any) a reasonable number of copies of a supplement to
or an amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such securities, 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 light of the circumstances under which they were made;

                    (vii)   otherwise use Commercially Reasonable Efforts to 
comply with all applicable rules and regulations of the SEC, and make available
to its security holders, as soon as reasonably practicable (but not more than
fifteen (15) months) after the effective date of the registration statement, an
earnings statement satisfying the provisions of Section 11(a) of the Securities
Act and Rule 158 promulgated thereunder, and furnish to each Holder covered by
such registration statement or any participating underwriter or agent a copy of
any amendment or supplement to such registration statement or prospectus five
(5) calendar days (or such

                                      12
<PAGE>
 
shorter period as may be practicable under the circumstances) prior to the
filing thereof with the SEC;

                    (viii)  provide and cause to be maintained a transfer agent
and registrar for all Registrable Securities covered by such registration
statement from and after a date not later than the effective date of such
registration statement;

                    (ix)    use Commercially Reasonable Efforts to, on or prior
to the effective date of such registration statement, list the Registrable
Securities covered by such registration statement on any securities exchange on
which the Registrable Securities are then listed;

                    (x)     cooperate with each Participating Holder and each
underwriter or agent participating in the disposition of such Registrable
Securities and their respective counsel in connection with any filings required
to be made with the National Association of Securities Dealers, Inc.;

                    (xi)    use Commercially Reasonable Efforts to prevent the
issuance by the SEC or any other governmental agency or court of a stop order,
injunction or other order suspending the effectiveness of such registration
statement and, if such an order is issued, use Commercially Reasonable Efforts
to cause such order to be lifted as promptly as practicable;

                    (xii)   take such other actions as the Requisite Holders of
such Registrable Securities shall reasonably request in order to expedite or
facilitate the disposition of such Registrable Securities;

                    (xiii)  promptly notify each Participating Holder and each
underwriter or agent, if any:

                            (A)  when such registration statement or any
prospectus used in connection therewith, or any amendment or supplement thereto,
has been filed and, with respect to such registration statement or any post-
effective amendment thereto, when the same has become effective;

                            (B)  of any written comments from the SEC with
respect to any filing referred to in clause (A) and of any written request by
the SEC for amendments or supplements to such registration statement or
prospectus;

                            (C)  of the notification to the Company by the SEC
of its initiation of any proceeding with respect to, or of the issuance by the
SEC of, any stop order suspending the effectiveness of such registration
statement; and

                            (D)  of the receipt by the Company of any
notification with respect to the suspension of the qualification of any
Registrable Securities for sale, resale or other disposition under the
applicable securities or blue sky laws of any jurisdiction;

                                      13
<PAGE>
 
                    (xiv)   cooperate with each Participating Holder and each
underwriter or agent participating in the distribution of such Registrable
Securities to facilitate the timely preparation and delivery of certificates
(which shall not bear any restrictive legends, other than as required by
applicable law) representing securities sold under a registration statement
hereunder, and enable such securities to be in such denominations and registered
in such names as such seller, underwriter or agent may request and keep
available and make available to the Company's transfer agent, prior to the
effectiveness of such registration statement, an adequate supply of such
certificates;

                    (xv)    not later than the effective date of such

respective counsel may reasonably request, in writing, to be included therein
with respect to any Registrable Securities being sold by such Holder to such
underwriter or agent, the purchase price being paid therefor by such underwriter
or agent and any other terms of the offering of such Registrable Securities;

                    (xvii)  during any period when a prospectus is required to
be delivered under the Securities Act, make timely periodic filings with the SEC
pursuant to and containing the information required by the Exchange Act (whether
or not the Company is required to make such filings pursuant to such Act); and

                    (xviii) in connection with an underwritten offering,
participate, to the extent reasonably requested by the Requisite Holders of the
securities included in the offering or the managing underwriter for the
offering, in customary efforts to sell the securities under the offering.

               (h)  AGREEMENTS OF CERTAIN HOLDERS

                    (i)     Each Participating Holder shall furnish to the
Company, in writing, such information regarding such Holder, the Registrable
Securities held by such Holder and the intended plan of distribution of such
securities as the Company may from time to time reasonably request in writing in
connection with such registration.

                    (ii)    Each Participating Holder agrees, by acquisition of
such Registrable Securities, that upon receipt of any notice (a "Suspension
Notice") from the Company of the suspension of the use of a Shelf Registration
Statement as contemplated by Section 2.1(d) (as limited pursuant to Section
2.3(e)) or of the happening of any event of the kind described in clause (vi) of
Section 2.3(g) hereof, such Holder will forthwith discontinue such Holder's
disposition of Registrable Securities pursuant to the registration statement
relating to such Registrable Securities until such Holder's receipt of the
copies of the supplemented or amended prospectus contemplated by clause (vi) of
Section 2.3(g) hereof or of a notice that such Holder may resume dispositions of

                                      14
<PAGE>
 
Registrable Securities pursuant to the registration statement (the period from
the date on which such Holder receives a Suspension Notice to the date on which
such Holder receives copies of the supplemental or amended prospectus being
herein called the "Suspension Period").  The Company shall take such actions as
are necessary to end the Suspension Period as promptly as practicable.  The
applicable time period for effectiveness in Section 2.3(c) shall be extended by
the number of days of a Suspension Period.

          2.4  UNDERWRITTEN OFFERINGS

               (a)  UNDERWRITTEN OFFERINGS IN CONNECTION WITH A DEMAND
REGISTRATION.  If requested by the underwriters for any underwritten offering in
connection with a registration pursuant to Section 2.1 hereof, the Company will
enter into an underwriting agreement with such underwriters for such offering,
such agreement (i) to be satisfactory in substance and form to the Company and
to the Requisite Holders, and (ii) to contain such representations and
warranties by the Company and the Participating Holders and such other terms as
are generally prevailing in agreements of such type, including, without
limitation, indemnities to the effect and to the extent provided in Section 2.6
hereof. Each Investor (so long as it or any of its Affiliates holds Registrable
Securities to be included in such registration) shall be a party to such
underwriting agreement and may, at its option, require that any or all of the
representations and warranties by, and the other agreements on the part of, the
Company to and for the benefit of such underwriters, also be made to and for its
benefit and that any or all of the conditions precedent to the obligations of
such underwriters under such underwriting agreement be conditions precedent to
its obligations thereunder.

               (b)  UNDERWRITTEN OFFERINGS IN CONNECTION WITH PIGGYBACK
REGISTRATIONS.  If the Company at any time proposes to register any of its
equity securities under the Securities Act as contemplated by Section 2.2 hereof
and such securities are to be distributed by or through one or more
underwriters, the Company will, if requested by any Participating Holder and
subject to Section 2.2(b) hereof, arrange for such underwriters to include
Registrable Securities to be offered and sold by such Holder or Holders among
the securities to be distributed by such underwriters. The Participating Holders
shall be parties to the underwriting agreement between the Company and such
underwriters, such agreement (i) to be satisfactory in substance and form to the
Company and to the Requisite Holders, and (ii) to contain such representations
and warranties by the Company and the Participating Holders and such other terms
as are generally prevailing in agreements of such type, including, without
limitation, indemnities to the effect and to the extent provided in Section 2.6
hereof. The Requisite Holders of the Registrable Securities included in such
offering may, at their option, require that any or all of the representations
and warranties by, and the other agreements on the part of, the Company to and
for the benefit of such underwriters, also be made to and for the benefit of the
Participating Holders and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement be conditions
precedent to the obligations of such Holders thereunder.

          2.5  PREPARATION; REASONABLE INVESTIGATION.  In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give Participating Holders, their
underwriters or

                                      15
<PAGE>
 
agents, if any, and their respective counsel and accountants, reasonable access
to its books and records and such opportunities to discuss the business of the
Company with its officers and the independent public accountants who have
certified its financial statements as shall be necessary, in the opinion of such
Holders' and such underwriters' or agents' respective counsel, to conduct a
reasonable investigation within the meaning of the Securities Act.

          2.6  INDEMNIFICATION

               (a) INDEMNIFICATION BY THE COMPANY.  The Company agrees to
indemnify and hold harmless, to the full extent permitted by law, each
Participating Holder, its directors, officers, shareholders, employees,
investment advisers, agents and Affiliates, either direct or indirect (and each
such Affiliate's directors, officers, shareholders, employees, investment
advisers and agents), and each other Person, if any, who controls such Persons
within the meaning of the Securities Act (each such Person, an "Indemnified
Party"), from and against any losses, claims, damages, liabilities or expenses,
joint or several (each a "Loss" and collectively, "Losses"), to which such
Indemnified Party may become subject under the Securities Act or otherwise, to
the extent that such Losses (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in any
registration statement under which such securities were registered under the
Securities Act (including all documents incorporated therein by reference), any
preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and the Company will
reimburse such Indemnified Party for any legal or any other expenses reasonably
incurred by it in connection with investigating or defending against any such
Loss, action or proceeding; provided that in any such case the Company shall not
be liable to any particular Indemnified Party to the extent that such Loss (or
action or proceeding in respect thereof) arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement, any such preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by such Indemnified
Party specifically for inclusion therein; and provided, further, that the
Company shall not be liable in any such case to the extent it is finally
determined by a court of competent jurisdiction that any such Loss (or action or
proceeding in respect thereof) arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made

                    (i)     in any such preliminary prospectus, if (A) it was
the responsibility of such Indemnified Party to provide the Person asserting
such Loss with a current copy of the final prospectus or summary prospectus
contained therein and such Indemnified Party failed to deliver or cause to be
delivered a copy of the final prospectus or summary prospectus contained therein
to such Person after the Company had furnished such Indemnified Party with a
sufficient number of copies of the same prior to the sale of Registrable
Securities to the Person asserting such Loss and (B) the final prospectus or
summary prospectus contained therein corrected such untrue statement or
omission; or

                                      16
<PAGE>
 
                    (ii)    in such final prospectus or summary prospectus
contained therein, if such untrue statement or omission is corrected in an
amendment or supplement to such final prospectus or summary prospectus contained
therein and such amendment or supplement has been delivered to the Indemnified
Party prior to the sale of Registrable Securities to the Person asserting such
Loss and the Indemnified Party thereafter fails to deliver the final prospectus
or summary prospectus contained therein as so amended or supplemented prior to
or concurrently with such sale after the Company had furnished such Indemnified
Party (in accordance with the notice provisions contained in Section 10 for
Persons who are parties to this Agreement) with a sufficient number of copies of
the same for delivery to purchasers of securities.

Such indemnity will remain in full force and effect regardless of any
investigation made by or on behalf of such Indemnified Party and shall survive
the transfer of such securities by such Indemnified Party.  The Company shall
also indemnify each other Person who participates (including as an underwriter)
in the offering or sale of Registrable Securities hereunder, their officers and
directors and each other Person, if any, who controls any such participating
Person within the meaning of the Securities Act to the same extent as provided
above with respect to Indemnified Parties.

               (b)  INDEMNIFICATION BY THE SELLERS.  The Company may require, as
a condition to including any Registrable Securities in any registration
statement filed pursuant to Sections 2.1 or 2.2 hereof and as a condition to
indemnifying such sellers pursuant to this Section 2.6, that the Company shall
have received an undertaking reasonably satisfactory to it from each
Participating Holder included in any such offering regarding its agreement to
indemnify and hold harmless and reimburse (in the same manner and to the same
extent as set forth in paragraph (a) of this Section 2.6) the Company, each
director, officer, employee and agent of the Company, and each other Person, if
any, who controls the Company within the meaning of the Securities Act, from and
against any Losses (or actions or proceedings, whether commenced or threatened,
in respect thereof) arising out of or based upon any untrue statement or alleged
untrue statement of a material fact contained in any registration statement
pursuant to which securities of such Holder are registered under the Securities
Act (including all documents incorporated therein by reference), any preliminary
prospectus, final prospectus or summary prospectus contained therein, or any
amendment or supplement thereto, or any omission or alleged omission from such
registration statement, preliminary prospectus, final prospectus or summary
prospectus, or any amendment or supplement thereto required to be stated therein
or necessary to make the statements therein not misleading, if (but only if)
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by such Participating Holder specifically for inclusion
therein; provided, however, that such Participating Holder shall not be
obligated to provide such indemnity to the extent that such Losses result,
directly or indirectly, from the failure of the Company to promptly amend or
take action to correct or supplement or to deliver timely any such registration
statement, prospectus, amendment or supplement based on corrected or
supplemental information provided in writing by such Participating Holder to the
Company expressly for such purpose; and provided further, that the obligation to
provide indemnification pursuant to this Section 2.6(b) shall be several, and
not joint and several, among such indemnifying parties. Notwithstanding anything
in this Section 2.6(b) to the contrary, 

                                      17
<PAGE>
 
in no event shall the liability of any Participating Holder under such indemnity
be greater in amount than the amount of the proceeds received by such
Participating Holder upon the sale of its Registrable Securities in the offering
to which the Losses relate.  Such indemnity shall remain in full force and
effect, regardless of any investigation made by or on behalf of the Company or
any such director, officer, employee, agent or participating or controlling
Person and shall survive the transfer of such securities by such Participating
Holder.

               (c)  NOTICES OF CLAIMS, ETC.  Promptly after receipt by an
Indemnified Party of notice of the commencement of any action or proceeding
involving a claim referred to in paragraph (a) or (b) of this Section 2.6, such
Indemnified Party will, if a claim in respect thereof is to be made against an
indemnifying party, give prompt written notice to the latter of the commencement
of such action, provided that the failure of any Indemnified Party to give
notice as provided herein shall not relieve the indemnifying party of its
obligations under this Section 2.6, except to the extent that the indemnifying
party is actually and materially prejudiced by such failure to give notice. In
case any such action is brought against an Indemnified Party, the indemnifying
party shall be entitled to participate in and to assume the defense thereof
(such assumption to constitute its acknowledgement of its agreement to indemnify
the Indemnified Party with respect to such matters), jointly with any other
indemnifying party similarly notified to the extent that it may wish, with
counsel reasonably satisfactory to such Indemnified Party, and after notice from
the indemnifying party to such Indemnified Party of its election so to assume
the defense thereof, the indemnifying party shall not be liable to such
Indemnified Party for any legal fees or other expenses subsequently incurred by
the latter in connection with the defense thereof other than reasonable costs of
investigation; provided, however, that if, in such Indemnified Party's
reasonable judgment, a conflict of interest between such indemnified and
indemnifying parties may exist in respect of such claim, such Indemnified Party
shall be entitled to separate counsel reasonably satisfactory to the
indemnifying party at the expense of the indemnifying party; and provided,
further, that, unless there exists a conflict of interest among indemnified
parties, all indemnified parties in respect of such claim shall be entitled to
only one counsel or firm of counsel for all such indemnified parties. In the
event an indemnifying party shall not be entitled, or elects not, to assume the
defense of a claim, such indemnifying party shall not be obligated to pay the
fees and expenses of more than one counsel or firm of counsel for all parties
indemnified by such indemnifying party in respect of such claim, unless in the
reasonable judgment of any such Indemnified Party a conflict of interest exists
between such Indemnified Party and any other of such indemnified parties in
respect of such claim, in which event the indemnifying party shall be obligated
to pay the fees and expenses of one additional counsel or firm of counsel for
such indemnified parties. No indemnifying party shall, without the consent of
the Indemnified Party, consent to entry of any judgment or enter into any
settlement that (i) does not include as an unconditional term thereof the giving
by the claimant or plaintiff to such Indemnified Party of a release from all
Losses in respect of such claim or litigation or (ii) would impose injunctive
relief on such Indemnified Party. No indemnifying party shall be subject to any
Losses for any settlement made without its consent, which consent shall not be
unreasonably withheld.

                                      18

               (d)  OTHER INDEMNIFICATION.  The provisions of this Section 2.6
shall be in addition to any other rights to indemnification or contribution
which an Indemnified Party may have pursuant to law, equity, contract or
otherwise.

               (e)  INDEMNIFICATION PAYMENTS.  The indemnification required by
this Section 2.6 shall be made by periodic payments of the amount thereof during
the course of the investigation or defense, promptly as and when bills are
received or Losses are incurred.

               (f)  CONTRIBUTION.  If for any reason the foregoing indemnity and
reimbursement is unavailable or is insufficient to hold harmless an Indemnified
Party under paragraph (a) or (b) of this Section 2.6, then each indemnifying
party shall contribute to the amount paid or payable by such Indemnified Party
as a result of any Loss (or actions or proceedings, whether commenced or
threatened, in respect thereof), including, without limitation, any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such Loss, action or proceeding, in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one
hand and the Indemnified Party on the other. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the indemnifying party or the
Indemnified Party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission. Notwithstanding anything in this Section 2.6(f) to the contrary, no
indemnifying party (other than the Company) shall be required pursuant to this
Section 2.6(f) to contribute any amount in excess of the amount by which the net
proceeds received by such indemnifying party from the sale of Registrable
Securities in the offering to which the Losses of the indemnified parties relate
exceeds the amount of any damages which such indemnifying party has otherwise
been required to pay by reason of such untrue statement or omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation.

SECTION 3.     RULE 144

               (a)  The Company will file the reports required to be filed by it
under the Securities Act and the Exchange Act and the rules and regulations
promulgated by the SEC thereunder and will take such further action as any
Holder may reasonably request, to the extent required from time to time to
enable the Holder to sell Registrable Securities without registration under the
Securities Act within the limitation of the exemptions provided by (i) Rule 144,
or (ii) any similar rule or regulation hereafter adopted by the SEC. Upon the
request of any Holder, the Company will deliver to that Holder a written
statement as to whether it has complied with such requirements, a copy of the
most recent annual or quarterly report of the Company, and such other reports or
documents so filed as a Holder may reasonably request in availing itself of any
rule or regulation of the SEC allowing a Holder to sell any such securities
without registration.

                                      19
<PAGE>
 
               (b)  If at any time the Company is not required to file reports
in compliance with either Section 13 or Section 15(d) of the Exchange Act, the
Company at its expense will, forthwith upon the request of any Holder make
available adequate current public information with respect to the Company within
the meaning of paragraph (c)(2) of Rule 144.

SECTION 4.     TERM

               This Agreement shall enter into force on the date hereof and
shall continue in full force and effect, subject to Section 16 hereof, until the
third (3rd) anniversary of the date hereof.

SECTION 5.     AMENDMENTS AND WAIVERS

               This Agreement may be amended, supplemented or modified only by a
writing (which makes reference to this Agreement) executed by the Company and
Holders holding at least fifty percent (50%) of the Registrable Securities then
held by all the Holders. Any term or condition of this Agreement may be waived
at any time by the party that is entitled to the benefit thereof, but no such
waiver shall be effective unless set forth in a written instrument duly executed
by or on behalf of the party waiving such term or condition. No waiver by any
party of any term or condition of this Agreement, in any one or more instances,
shall be deemed to be or construed as a waiver of the same term or condition of
this Agreement on any future occasion.

SECTION 6.     ENTIRE AGREEMENT

               This Agreement supersedes all prior discussions and agreements
between the parties with respect to the subject matter hereof and contains the
sole and entire agreement between the parties hereto with respect to the subject
matter hereof.

SECTION 7.     NO THIRD-PARTY BENEFICIARY

               The terms and provisions of this Agreement are intended solely
for the benefit of each party, their respective Successors or permitted assigns
and it is not the intention of the parties to confer third-party beneficiary
rights upon any other Person other than (i) any Affiliate of any Investor, (ii)
any transferee, direct or indirect, of any of the Registrable Securities held by
any Investor or any of their respective Affiliates, or (iii) any other Person
entitled to notice of the registration of Registrable Securities under Sections
2.1(c) or 2.2(a) hereof or to indemnity under Section 2.6 hereof.

SECTION 8.     INVALID PROVISIONS

               If any provision of this Agreement is held to be illegal, invalid
or unenforceable under any present or future law, (i) such provision will be
fully severable, (ii) this Agreement will be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part hereof,
(iii) the remaining provisions of this Agreement will remain in full force and
effect and will not be affected by the illegal, invalid or unenforceable
provision or by its severance herefrom and (iv) in lieu of such illegal, invalid
or unenforceable provision, there will be added

                                      20
<PAGE>
 
automatically as a part of this Agreement a legal, valid and enforceable
provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible.

SECTION 9.     NOMINEES FOR BENEFICIAL OWNERS

               In the event that any Registrable Securities are held by a
nominee for the beneficial owner thereof, the beneficial owner thereof may, at
its election, be treated as the holder of such Registrable Securities for
purposes of request or other action by any Holder or Holders pursuant to this
Agreement or any determination of any amount of shares of Registrable Securities
held by any Holder or Holders of Registrable Securities contemplated by this
Agreement. If the beneficial owner of any Registrable Securities so elects, the
Company may require assurances reasonably satisfactory to it of such owner's
beneficial ownership of such Registrable Securities. For purposes of this
Agreement, "beneficial ownership" and "beneficial owner" refer to beneficial
ownership as defined in Rule 13d-3 (without regard to the 60-day provision in
paragraph (d)(1)(i) thereof) under the Exchange Act.

requests and other communications shall be sent to the Registered Addresses and
telecopy numbers provided to the Company and the other parties hereto by notice
as herein provided and referencing this Agreement.  All such notices, requests

facsimile transmission to the facsimile number as provided in this Section 10,
be deemed given upon receipt, and (C) if delivered by courier service or by mail
in the manner described above to the address as provided in this Section 10, be

assigns of Registrable Securities. Each Investor may assign any of its rights
hereunder (in whole or in part) to one or more permitted transferees of
Registrable Securities; provided, however, that any such permitted transferees
of Registrable Securities agrees in writing, in form and substance satisfactory
to the Company, to be bound by all of the terms and provisions hereof and to

assignment shall be binding upon or obligate the Company to any such assignee
unless and until (a) the Company has received notice of the assignment as herein
provided, which notice (i) references this Agreement and (ii) sets forth the
Registered Address of any assignee for the purpose of any notices hereunder.

extraordinary character, and that in the event of a breach by any such party

shall be entitled to specific performance and injunctive and other equitable
relief in addition to any other remedy to which it may be entitled at law or in
equity.
