(C)           CONDUCT OF INDEMNIFICATION PROCEEDINGS. IF ANY PROCEEDING SHALL BE
BROUGHT OR ASSERTED AGAINST ANY PERSON ENTITLED TO INDEMNITY HEREUNDER (AN
“INDEMNIFIED PARTY”), SUCH INDEMNIFIED PARTY SHALL PROMPTLY NOTIFY THE PERSON
FROM WHOM INDEMNITY IS SOUGHT (THE “INDEMNIFYING PARTY”) IN WRITING, AND THE
INDEMNIFYING PARTY SHALL ASSUME THE DEFENSE THEREOF, INCLUDING THE EMPLOYMENT OF
COUNSEL REASONABLY SATISFACTORY TO THE INDEMNIFIED PARTY AND THE PAYMENT OF ALL
FEES AND EXPENSES INCURRED IN CONNECTION WITH DEFENSE THEREOF; PROVIDED, THAT
THE FAILURE OF ANY INDEMNIFIED PARTY TO GIVE SUCH NOTICE SHALL NOT RELIEVE THE
INDEMNIFYING PARTY OF ITS OBLIGATIONS OR LIABILITIES PURSUANT TO THIS AGREEMENT,
UNLESS THE FAILURE TO GIVE SUCH NOTICE IS MATERIALLY PREJUDICIAL TO THE
INDEMNIFYING PARTY’S ABILITY TO DEFEND.

An Indemnified Party shall have the right to employ separate counsel in any such
Proceeding and to participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party or Parties
unless:  (1) the Indemnifying Party has agreed in writing to pay such fees and
expenses; (2) the Indemnifying Party shall have failed promptly to assume the
defense of such Proceeding and to employ counsel reasonably satisfactory to such
Indemnified Party in any such Proceeding; or (3) the named parties to any such
Proceeding (including any impleaded parties) include both such Indemnified Party
and the Indemnifying Party, and such Indemnified Party shall have been advised
by counsel that a conflict of interest exists if the same counsel were to
represent such Indemnified Party and the Indemnifying Party (in which case, if
such Indemnified Party notifies the Indemnifying Party in writing that it elects
to employ separate counsel at the expense of the Indemnifying Party, the
Indemnifying Party shall not have the right to assume the defense thereof and
such counsel shall be at the expense of the Indemnifying Party).  The
Indemnifying Party shall not be liable for any settlement of any such Proceeding
effected without its written consent, which consent shall not be unreasonably
withheld.  No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending Proceeding in respect of
which any Indemnified Party is a party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability on claims
that are the subject matter of such Proceeding.

All fees and expenses of the Indemnified Party (including reasonable fees and
expenses to the extent incurred in connection with investigating or preparing to
defend

8

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

 

such Proceeding in a manner not inconsistent with this Section) shall be paid to
the Indemnified Party, as incurred, within ten Trading Days of written notice
thereof to the Indemnifying Party (regardless of whether it is ultimately
determined that an Indemnified Party is not entitled to indemnification
hereunder; provided, that the Indemnifying Party may require such Indemnified
Party to undertake to reimburse all such fees and expenses to the extent it is
finally judicially determined that such Indemnified Party is not entitled to
indemnification hereunder).

(D)           CONTRIBUTION.  IF A CLAIM FOR INDEMNIFICATION UNDER SECTION 5(A)
OR 5(B) IS UNAVAILABLE TO AN INDEMNIFIED PARTY (BY REASON OF PUBLIC POLICY OR
OTHERWISE), THEN EACH INDEMNIFYING PARTY, IN LIEU OF INDEMNIFYING SUCH
INDEMNIFIED PARTY, SHALL CONTRIBUTE TO THE AMOUNT PAID OR PAYABLE BY SUCH
INDEMNIFIED PARTY AS A RESULT OF SUCH LOSSES, IN SUCH PROPORTION AS IS
APPROPRIATE TO REFLECT THE RELATIVE FAULT OF THE INDEMNIFYING PARTY AND
INDEMNIFIED PARTY IN CONNECTION WITH THE ACTIONS, STATEMENTS OR OMISSIONS THAT
RESULTED IN SUCH LOSSES AS WELL AS ANY OTHER RELEVANT EQUITABLE CONSIDERATIONS. 
THE RELATIVE FAULT OF SUCH INDEMNIFYING PARTY AND INDEMNIFIED PARTY SHALL BE
DETERMINED BY REFERENCE TO, AMONG OTHER THINGS, WHETHER ANY ACTION IN QUESTION,
INCLUDING ANY UNTRUE OR ALLEGED UNTRUE STATEMENT OF A MATERIAL FACT OR OMISSION
OR ALLEGED OMISSION OF A MATERIAL FACT, HAS BEEN TAKEN OR MADE BY, OR RELATES TO
INFORMATION SUPPLIED BY, SUCH INDEMNIFYING PARTY OR INDEMNIFIED PARTY, AND THE
PARTIES’ RELATIVE INTENT, KNOWLEDGE, ACCESS TO INFORMATION AND OPPORTUNITY TO
CORRECT OR PREVENT SUCH ACTION, STATEMENT OR OMISSION.  THE AMOUNT PAID OR
PAYABLE BY A PARTY AS A RESULT OF ANY LOSSES SHALL BE DEEMED TO INCLUDE, SUBJECT
TO THE LIMITATIONS SET FORTH IN SECTION 5(C), ANY REASONABLE ATTORNEYS’ OR OTHER
REASONABLE FEES OR EXPENSES INCURRED BY SUCH PARTY IN CONNECTION WITH ANY
PROCEEDING TO THE EXTENT SUCH PARTY WOULD HAVE BEEN INDEMNIFIED FOR SUCH FEES OR
EXPENSES IF THE INDEMNIFICATION PROVIDED FOR IN THIS SECTION WAS AVAILABLE TO
SUCH PARTY IN ACCORDANCE WITH ITS TERMS.

The parties hereto agree that it would not be just and equitable if contribution
pursuant to this Section 5(d) were determined by pro rata allocation or by any
other method of allocation that does not take into account the equitable
considerations referred to in the immediately preceding paragraph. 
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.

The indemnity and contribution agreements contained in this Section are in
addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

6.             MISCELLANEOUS

OF ANY OF THEIR OBLIGATIONS UNDER THIS AGREEMENT, EACH HOLDER OR THE COMPANY, AS

ANNEX A

Plan of Distribution

The Selling Stockholders and any of their pledgees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares
of Common Stock on any stock exchange, market or trading facility on which the
shares are traded or in private transactions.  These sales may be at fixed or
negotiated prices.  The Selling Stockholders may use any one or more of the
following methods when selling shares:

•                  ordinary brokerage transactions and transactions in which the
broker-dealer solicits purchasers;

•                  block trades in which the broker-dealer will attempt to sell
the shares as agent but may position and resell a portion of the block as
principal to facilitate the transaction;

•                  purchases by a broker-dealer as principal and resale by the
broker-dealer for its account;

•                  an exchange distribution in accordance with the rules of the
applicable exchange;

•                  privately negotiated transactions;

•                  short sales

•                  broker-dealers may agree with the Selling Stockholders to
sell a specified number of such shares at a stipulated price per share;

•                  a combination of any such methods of sale; and

•                  any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other
brokers-dealers to participate in sales.  Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated.  The Selling Stockholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved.

The selling stockholder may from time to time pledge or grant a security
interest in some or all of the Shares or common stock owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell the shares of common stock from time to time under
this prospectus, or under an amendment to this prospectus under Rule 424(b)(3)
or other applicable provision of the Securities Act of 1933

14

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

 

amending the list of selling stockholders to include the pledgee, transferee or
other successors in interest as selling stockholders under this prospectus.

The selling stockholders also may transfer the shares of common stock in other
circumstances, in which case the transferees, pledgees or other successors in
interest will be the selling beneficial owners for purposes of this prospectus.

The Selling Stockholders and any broker-dealers or agents that are involved in
selling the shares may be deemed to be “underwriters” within the meaning of the
Securities Act in connection with such sales.  In such event, any commissions
received by such broker-dealers or agents and any profit on the resale of the
shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act.  The Selling Stockholders have informed the
Company that it does not have any agreement or understanding, directly or
indirectly, with any person to distribute the Common Stock.

The Company is required to pay all fees and expenses incident to the
registration of the shares, including $5,000 of fees and disbursements of
counsel to the Selling Stockholders.  The Company has agreed to indemnify the
Selling Stockholders against certain losses, claims, damages and liabilities,
including liabilities under the Securities Act.
