                        SEPARATION AGREEMENT AND RELEASE

         THIS SEPARATION AGREEMENT AND RELEASE (this "Agreement") is made by and
between Parker Drilling Company ("Company") and Tom Wingerter ("Employee").

                                     PURPOSE

         Company has informed Employee that his employment will terminate on
September 30, 2003 ("the Termination Date"). Consistent with the terms,
conditions and limitations of the Employment Agreement between Company and
Employee dated November 1, 2002 as amended and restated ("Employment
Agreement"), Employee is eligible to receive certain payments and benefits
subject to the execution of this Agreement. Employee agrees that all such
payments and benefits described herein are in full and complete satisfaction of
any and all obligations the Company has or may have to Employee and that the
payments represent something of value beyond anything that he is entitled to. To
achieve a final and amicable resolution of the employment relationship in all
its aspects and in consideration of the mutual covenants and promises herein
contained and other good and valuable consideration, the receipt and
sufficiently of which is hereby acknowledged, the parties hereto agree as
follows:

                      COVENANTS AND OBLIGATIONS OF COMPANY

         Payment of Separation Benefits: The Company shall pay to Employee a
severance payment in a lump sum amount of $491,809 and provide the following
benefits, subject to the Employee satisfying all specified conditions described
herein:

             -    Group Health/Dental Plan ("Health Plan") coverage for 18
                  months for Employee and spouse at no monthly contribution cost
                  to Employee, subject to the terms and limitations contained in
                  the Employment Agreement and further subject to the terms of
                  the Health Plan. Spouse will only be eligible for this
                  provision if she remains married to Employee throughout the
                  time period.

             -    Outplacement Services (capped at $15,000). Company will select
                  the outplacement firm.

             -    Company will extend the vesting dates for stock option grants
                  through September 30, 2005 and the expiration dates for such
                  stock option grants will remain in effect

<PAGE>

                  consistent with the information contained in the optionee
                  statement dated December 31, 2002. Both of these benefits are
                  subject to Board approval.

             -    The Company agrees to waive, in its entirety, and without
                  reservation, Section 17 of the Employment Agreement. Section
                  17 specifically pertains to a one year restrictive covenant
                  imposed against the Employee, effective on the termination
                  date, for performing any similar duties as those performed
                  while at the company, either directly or indirectly, for
                  customers of the company, or any affiliate or any business
                  entity that sells, provides or develops products or services
                  competitive with any products or services sold, provided or
                  developed by the company or any affiliate. Notwithstanding the
                  waiving of Section 17 in its entirety, all other restrictions
                  contained in the Employment Agreement remain in full force and
                  effect.

         Payment of the lump sum will be subject to normal payroll taxes and
shall be mailed to Employee as soon as administratively feasible after his
employment is terminated.

         Other Benefits: Neither this Agreement nor the release contained herein
shall waive Employee's right to any vested, accrued benefit under a Company
stock option plan or benefit plan in which Employee is a qualified participant,
including, but not limited to, any benefits under a pension or retirement plan.

                      COVENANTS AND OBLIGATIONS OF EMPLOYEE

         In consideration of the promises and covenants of Company contained in
this Agreement, Employee agrees to the following:

         Waiver of Reinstatement and Future Employment: Employee forever waives
and relinquishes any right or claim to reinstatement to active employment with
Company, its affiliates, subsidiaries, divisions, successors and parent
companies. Employee further acknowledges that Company has no obligation to
rehire or return Employee to active duty at any time in the future.

         RELEASE: EXCEPT AS OTHERWISE SET FORTH IN THIS AGREEMENT, EMPLOYEE
FULLY AND FOREVER RELIEVES, RELEASES AND DISCHARGES COMPANY, ITS PREDECESSORS,
SUCCESSORS, SUBSIDIARIES, OPERATING UNITS, AFFILIATES, DIVISIONS, AND PARENT
COMPANIES AND THE AGENTS, REPRESENTATIVES,

          "REGISTRABLE SECURITIES" means (i) the Shares and any and all shares
     of Common Stock issued or issuable at any time or from time to time in
     respect of which I/O has previously or may in the future grant in writing
     registration rights (collectively, the "Registrable Common"); and (ii) any
     Common Stock issued or issuable at any time or from time to time in respect
     of the Shares or the Registrable Common upon a stock split, stock dividend,
     recapitalization or other similar event involving I/O; PROVIDED, HOWEVER,
     that shares of Common Stock which are Registrable Securities shall cease to
     be Registrable Securities upon any sale pursuant to a Registration
     Statement, Section 4(1) of the Securities Act or

                                     -1-

     Rule 144 under the Securities Act, or any sale in any manner to a person
     or entity which, by virtue of Section 3.2 of this Agreement, is not
     entitled to the rights provided by this Agreement.

          The terms "REGISTER," "REGISTERED", and "REGISTRATION" refer to a

     Common Stock is offered and sold on a firm commitment basis through one or
     more underwriters, all pursuant to an underwriting agreement to which I/O
     and the underwriters, among others, are parties.

2.   REGISTRATION RIGHTS.

     2.1  PIGGYBACK REGISTRATION.

          (a)  NOTICE OF REGISTRATION.  If at any time during the term of this
     Agreement, I/O registers any of its Common Stock for its own account or for
     the account of any other stockholders relating to an Underwritten Public
     Offering, I/O shall:

               (i)  promptly, but in any event at least twenty (20) days before
          I/O files a registration statement pursuant to an Underwritten Public

                                     -2-
<PAGE>

          Offering, give to the Stockholder written notice; and

               (ii) subject to Section 2.9 hereof, include in such registration
          (and any related blue sky laws qualification) the Registrable
          Securities as the Stockholder requests in a writing delivered to I/O
          within (ten) 10 days after receipt of I/O's written notice delivered
          pursuant to Section 2.1(a)(i) above.  I/O shall have no obligation to
          include in the registration any Registrable Securities of the
          Stockholder from whom a written request was not timely received.
          Notwithstanding the forgoing to the contrary, in the event that the
          Stockholder requests inclusion of Registrable Securities in an
          Underwritten Public Offering prepared by I/O for the account of
          another stockholder, I/O shall only have the obligation to include
          such Registerable Securities, if any, as I/O shall have the right
          (contractual or otherwise) to include in such Underwritten Public
          Offering.

           (b) RIGHT TO TERMINATE REGISTRATION. I/O shall have the right to
     terminate or withdraw any registration initiated by I/O under this Section
     2.1 prior to the effectiveness of the registration whether the Stockholder
     has elected to include its Registrable Securities in the registration;
     PROVIDED, HOWEVER, that in such event, I/O shall promptly pay all
     reasonable out-of-pocket costs and expenses of the Stockholder incurred in
     connection with the terminated registration.

     2.2  DEMAND REGISTRATIONS.  At any time from and after the effective date
of this Agreement and during the term of this Agreement, the Stockholder may
make up to two written requests for registration under the Securities Act,
pursuant to this Section 2.2 of all or part of its Registrable Securities (each
a "Demand Registration").  Each such request will specify the number of shares
of Registrable Securities proposed to be sold and will also specify the intended
method of disposition thereof.  The Company shall not be required to effect more
than two Demand Registrations pursuant to this Section 2.2, and each such Demand
Registration shall not be made for less than one million (1,000,000) shares of
Registrable Securities.  If a registration has become effective but is withdrawn
before completion of the offering contemplated thereby, then such registration
shall not count as either of the Demand Registrations contemplated by this
Section 2.2.

          (a)  UNDERWRITTEN PUBLIC OFFERING.  If a Demand Registration is in the
     form of an underwritten offering, the Stockholder shall select the
     underwriter for such offering subject to the approval of the Company (which
     approval shall not be unreasonably withheld), and the Company shall enter
     into an underwriting agreement with such underwriter containing
     representations, warranties,

                                     -3-
<PAGE>

     indemnities and agreements then customarily included by an issuer in
     underwriting agreements with respect to secondary distributions.  The
     Company shall not cause the registration under the Securities Act of any
     other shares of its Common Stock to become effective (other than
     registration of an employee stock plan, or registration in connection
     with any Rule 145 or similar transaction) during the effectiveness of a
     registration requested hereunder for an underwritten public offering if,
     in the judgment of the underwriter or underwriters, such registration
     would adversely affect the offering of the Registrable Securities
     subject to the Demand Registration.

          (b)  INCLUSION OF ADDITIONAL SHARES.  The Company may include in a
     registration pursuant to this Section 2.2 securities for its own account or
     for the account of other third parties (including officers and employees of
     the Company), in amounts as determined by the Company's Board of Directors
     ("Additional Shares") so long as the inclusion thereof does not in any way
     exclude or otherwise impair the rights of the Stockholder who has requested
     registration pursuant to Section 2.2 above to include in such registration
     all Registrable Securities so requested.  Notwithstanding any other
     provision of this Agreement to the contrary, if the underwriter managing
     the offering determines that, because of marketing factors, all of the
     Registrable Securities and Additional Shares requested to be registered may
     not be included in the offering, then all or a portion of the Additional
     Shares shall be excluded to the extent so required by such limitation,
     prior to the exclusion, if any, of Registrable Securities of the
     Stockholder.  To facilitate the allocation of shares in accordance with the
     above provisions, the Company or the underwriters may round the number of
     shares allocated to any person to the nearest 100 shares.

     2.3  EXPENSES OF REGISTRATION.  All Registration Expenses incurred in
connection with registrations pursuant to (i) Section 2.1 piggyback
registrations shall be borne by I/O, and (ii) Section 2.2 demand registrations
shall be borne by the Stockholder.  All Selling Expenses relating to securities
registered on behalf of the Stockholder pursuant to Sections 2.1 and 2.2 shall
be borne by the Stockholder.

     2.4  I/O'S OBLIGATIONS IN REGISTRATION.  Whenever the Stockholder has
requested that any Registrable Securities be registered pursuant to this
Agreement, the Company will use its reasonable best efforts to effect the
registration and the sale of such Registrable Securities under the Securities
Act, as provided herein, and as expeditiously as possible:

     (a)  prepare and file with the Commission as soon as practicable but in no
event later than sixty (60) days after receipt of a request to file a
registration statement with

                                     -4-
<PAGE>

respect to Registrable Securities, a registration statement on any form for
which the Company then qualifies or which counsel for the Company shall deem
appropriate and which form shall be available for the sale of such issue of
Registrable Securities in accordance with the intended method of distribution
thereof, and use its best efforts to cause such registration statement to
become effective as promptly as practicable thereafter; PROVIDED, that if the
Company shall furnish to the Stockholders a certificate signed by the Chief
Executive Officer of the Company stating that in the good faith reasonable
judgment of the Board of Directors it would be significantly disadvantageous
to the Company and its stockholders for such a registration statement to be
filed on or before the date filing would be required or to become effective,
the Company shall have an additional period of not more than one-hundred
fifty (150) days within which to file (or before which it requests the
effectiveness of) such registration statement; and PROVIDED, FURTHER, that
before filing a registration statement or prospectus or any amendments or
supplements thereto, the Company will (i) furnish to counsel selected by each
seller of Registrable Securities copies of all such documents proposed to be
filed and (ii) notify each seller of Registrable Securities of any stop order
issued or threatened by the Commission and take all actions required to
prevent the entry of such stop order or to remove it if entered;

     (b)  prepare and file with the Commission such amendments and supplements
to such registration statement and the prospectus used in connection therewith
as may be necessary to keep such registration statement effective (and such
prospectus current as required by the Securities Act) for a period of not less
than 80 days or such shorter period which will terminate when all Registrable
Securities covered by such registration statement have been sold (but not before
the expiration of the applicable period referred to in Section 4(3) of the
Securities Act and Rule 174 thereunder, if applicable), and comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the sellers thereof set
forth in such registration statement;

     (c)  furnish to each seller of Registrable Securities to be included in a
registration statement copies of such registration statement as filed and each
amendment and supplement thereto (in each case including all exhibits thereto),
the prospectus included in such registration statement (including each
preliminary prospectus) and each amendment and supplement thereto and such other
documents as such seller may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by such seller;

     (d)  use its reasonable best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions as any seller

                                     -5-
<PAGE>

reasonably requests and do any and all other acts and things which may be
necessary or advisable to enable such seller to consummate the disposition in
such jurisdictions of the Registrable Securities owned by such seller;
PROVIDED, that the Company will not be required to (i) qualify generally to
do business in any jurisdiction where it would not otherwise be required to
qualify but for this Section 2.4(d), (ii) subject itself to taxation in any
such jurisdiction or (iii) consent to general service of process in any such
jurisdiction, but the Company will be required to consent to service of
process in actions arising out of or in connection with the sale of the
Registrable Securities or any violation of state securities laws;

     (e)  use its reasonable best efforts to cause the Registrable Securities
covered by such registration statement to be registered with or approved by any
other governmental agencies or authorities as may be necessary by virtue of the
business and operations of the Company to enable the seller or sellers thereof
to consummate the disposition of such Registrable Securities;

     (f)  enter into customary agreements (including an underwriting agreement
in customary form) and take such other actions as are required in order to
expedite or facilitate the disposition of such Registrable Securities; and

     (g)   cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed, provided that the applicable listing requirements are satisfied.

     The Company may require each seller of Registrable Securities as to which
any registration is being effected to furnish to the Company such information
regarding matters relating to such seller's Registrable Securities as are
customary and as the Company may from time to time reasonably request in
writing.

     In addition, the management of I/O will, without unduly interfering with
the business and operations of I/O, cooperate to a commercially reasonable
degree in connection with any Stockholder request that Registrable Securities be
registered pursuant to this Agreement, including customary "road show"
presentations.

     2.5  INDEMNIFICATION.

           (a) To the extent permitted by law, I/O will indemnify and hold
     harmless Stockholder, each of its directors and officers and each person
     who controls Stockholder within the meaning of Section 15 of the Securities
     Act, with respect to registration, qualification or compliance which has
     been effected pursuant to this Agreement, against all expenses, claims,
     losses, actions, damages

                                     -6-
<PAGE>

     or liabilities to the extent to which each such person is subject,
     including any of the foregoing incurred in settlement of any litigation,
     commenced or threatened, to the extent such expenses, claims, losses,
     damages or liabilities (or proceedings in respect thereof) arise out of
     or are based on any untrue statement (or alleged untrue statement) of a
     material fact contained in any registration statement, prospectus,
     offering circular or other document, or any amendment or supplement
     thereto, incident to any such registration, qualification or compliance,
     or arise out of or are based on any omission (or alleged omission) to
     state therein a material fact required to be stated therein or necessary
     to make the statements therein, in light of the circumstances in which
     they were made, not misleading, or any violation by I/O of the
     Securities Act or any rule or regulation promulgated under the
     Securities Act applicable to I/O in connection with any such
     registration, qualification or compliance, and I/O will reimburse the
     indemnified persons, for any legal and any other expenses reasonably
     incurred in connection with investigating, preparing or defending any
     such claim, loss, damage, liability or action, PROVIDED, HOWEVER, that
     the indemnity contained herein shall not apply to amounts paid in
     settlement of any claim, loss, damage, liability or expense if
     settlement is effected without the consent of I/O (which consent shall
     not unreasonably be withheld); PROVIDED, FURTHER, that I/O will not be
     liable in any such case to the extent that any such claim, loss, damage,
     liability or expense arises out of or is based on any untrue statement
     or omission or alleged untrue statement or omission, made in reliance
     upon and in conformity with information furnished to I/O expressly for
     inclusion in such registration by the Stockholder.  Notwithstanding the
     foregoing, insofar as the foregoing indemnity relates to any such untrue
     statement (or alleged untrue statement) or omission (or alleged
     omission) made in the preliminary prospectus but eliminated or remedied
     in the amended prospectus on file with the Commission at the time the
     registration statement becomes effective or in the final prospectus
     filed with the Commission pursuant to the applicable rules of the
     Commission or in any supplement or addendum thereto, the indemnity
     agreement herein shall not inure to the benefit of Stockholder if a copy
     of the final prospectus filed pursuant to such rules, together with all
     supplements and addenda thereto, was not furnished to the person or
     entity asserting the loss, liability, claim or damage at or prior to the
     time such furnishing is required by the Securities Act.

           (b) To the extent permitted by law, the Stockholder will, if
     securities held by the Stockholder are included in the securities as to
     which the registration, qualification or compliance is being effected
     pursuant to the terms of this Agreement, indemnify and hold harmless I/O,
     each of its directors and officers, each person who controls I/O within the
     meaning of Section 15 of the Securities Act, and each other person selling
     I/O's securities covered by such registration

                                     -7-
<PAGE>

     statement, each of such person's officers and directors and each person
     controlling such persons within the meaning of Section 15 of the
     Securities Act, against all claims, losses, damages and liabilities (or
     actions in respect thereof) to the extent to which such person or entity
     is subject, arising out of or based on any untrue statement (or alleged
     untrue statement) of a material fact contained in any such registration
     statement, prospectus, offering circular or other document, or arising
     out of or based on 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, or any violation by the Stockholder
     of any rule or regulation promulgated under the Securities Act
     applicable to the Stockholder and relating to action or inaction
     required of the Stockholder in connection with any such registration,
     qualification or compliance, and will reimburse I/O, such other persons,
     such directors, officers, persons or control persons for any legal or
     other expenses reasonably incurred in connection with investigating or
     defending any such claim, loss, damage, liability or action, in each
     case to the extent, but only to the extent, that such untrue statement
     (or alleged untrue statement) or omission (or alleged omission) is made
     in such registration statement, prospectus, offering circular or other
     document in reliance upon and in conformity with information furnished
     to I/O by the Stockholder expressly for inclusion in such registration;
     PROVIDED, HOWEVER, that the indemnity contained herein shall not apply
     to amounts paid in settlement of any claim, loss, damage, liability or
     expense if settlement is effected without the consent of the Stockholder
     (which consent shall not be unreasonably withheld). Notwithstanding the
     foregoing, the liability of the Stockholder under this subsection (b)
     shall be limited in an amount equal to the net proceeds from the sale of
     the Shares sold by the Stockholder, unless such liability arises out of
     or is based on intentional misconduct or an intentional omission by the
     Stockholder, in which case such limitation shall not apply.

          (c)  Each party entitled to indemnification under this Section 2.5
     (the "Indemnified Party") shall give notice to the party required to
     provide indemnification (the "Indemnifying Party") promptly after such
     Indemnified Party has actual knowledge of any action or proceeding
     commenced against, or written demand made on any such party in respect of
     which indemnity may be sought, and shall permit the Indemnifying Party to
     assume the defense of any such claim or any litigation resulting therefrom,
     provided that counsel for the Indemnifying Party, who shall conduct the
     defense of such claim or litigation, shall be approved by the Indemnified
     Party (whose approval shall not unreasonably be withheld), and the
     Indemnified Party may participate in such defense at such party's expense,
     and provided further that the failure of any Indemnified Party to give
     notice as provided herein shall not relieve the

                                     -8-
<PAGE>

     Indemnifying Party of its obligations under this Agreement unless the
     failure to give such notice is materially prejudicial to an Indemnifying
     Party's ability to defend such action and provided further, that the
     Indemnifying Party shall not assume the defense for matters as to which
     there is a conflict of interest or as to which the Indemnifying Party is
     asserting separate or different defenses, which defenses are
     inconsistent with the defenses of the Indemnified Party. No Indemnifying
     Party, in the defense of any such claim or litigation, shall, except
     with the consent of each Indemnified Party, consent to entry of any
     judgment or enter into any settlement which does not include as an
     unconditional term the giving by the claimant or plaintiff to such
     Indemnified Party of a release from all liability in respect to such
     claim or litigation. No Indemnified Party shall consent to entry of any
     judgment or enter into any settlement without the consent of each
     Indemnifying Party.

          (d)  If the indemnification provided for in this Section 2.5 is
     unavailable to an Indemnified Party in respect of any otherwise indemnified
     losses, claims, damages or liabilities, 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,
     claims, damages or liabilities in such proportion as is appropriate to
     reflect the relative fault of I/O on the one hand and the Stockholder on
     the other in connection with the statements or omissions which resulted in
     such losses, claims, damages or liabilities, as well as any other relevant
     equitable considerations. The relative fault of I/O on the one hand and the
     Stockholder on the other shall be determined by reference to, among other
     things, whether the untrue or alleged untrue statement of material fact or
     the omission or alleged omission to state a material fact relates to
     information supplied by I/O or by the Stockholder and the parties' relevant
     intent, knowledge, access to information and opportunity to correct or
     prevent such statement or omission. I/O and the Stockholder agree that it
     would not be just and equitable if contribution pursuant to this Section
     2.5(d) were based solely upon the number of entities from whom contribution
     was requested or by any other method of allocation which does not take
     account of the equitable considerations referred to above in this Section
     2.5(d). The amount paid or payable by an Indemnified Party as a result of
     the losses, claims, damages and liabilities referred to above in this
     Section 2.5(d) shall be deemed to include any legal or other expenses
     reasonably incurred by such Indemnified Party in connection with
     investigating or defending any such action or claim, subject to the
     provisions of Section 2.5(c) hereof.  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 (within the meaning of Section 11(f)
     of the Securities Act).

                                     -9-

     2.6  CERTAIN INFORMATION.  The Stockholder agrees, with respect to any
Registrable Securities included in any registration, to furnish to I/O that
information regarding the Stockholder, the Registrable Securities and the
distribution proposed by the Stockholder as I/O may reasonably request in
writing and as shall be required in connection with any registration,
qualification or compliance.

     2.7  "LOCK-UP" AGREEMENT.  With respect to any registration under Section
2.1, the Stockholder, if requested by I/O and/or the managing underwriter of
Common Stock or other securities of I/O, shall agree not to sell or otherwise
transfer or dispose of any Registrable Securities or other securities of I/O
held by the Stockholder within 14 days prior to, and for a specified period of
time (not to exceed 120 days) following, the effective date of a registration
statement.  Such agreement shall be in writing in a form reasonably satisfactory
to the Stockholder, I/O and such underwriter.  I/O may impose stop transfer
instructions with respect to the Registrable Securities or other securities
subject to the foregoing restriction until the end of the lock-up period.

     2.8  RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Securities ("Restricted Securities" is defined for
purposes of this Agreement as defined in Rule 144 under the Securities Act) to
the public without registration, I/O agrees, during the term of this Agreement,
to use its best lawful efforts to:

          (a)  Make and keep public information available, as those terms are
     understood and defined in Rule 144 under the Securities Act, at all times
     during which I/O is subject to the reporting requirements of the Securities
     Exchange Act of 1934, as amended (the "Exchange Act");

          (b)  File with the Commission in a timely manner all reports and other
     documents required of I/O under the Securities Act and the Exchange Act (at
     all times during which I/O is subject to such reporting requirements); and

          (c)  So long as the Stockholder owns any Restricted Securities, to
     furnish to the Stockholder upon request a written statement by I/O as to
     its compliance with the reporting requirements of Rule 144 and with regard
     to the  Securities Exchange Act of 1934 (at all times during which I/O is
     subject to such reporting requirements), a copy of the most recent annual
     or quarterly report of I/O, and such other reports and documents of I/O and
     other information in the possession of or reasonably obtainable by I/O as
     the Stockholder may reasonably request in availing itself of any rule or
     regulation of the Commission allowing the Stockholder to sell securities
     without registration.

     2.9  UNDERWRITING.  The right of the Stockholder to registration under this
Agreement under Section 2.1 shall be conditioned upon the Stockholder's
participation in the underwriting.  The inclusion of Stockholder's Registrable
Securities in the underwriting may be limited.  The Stockholder shall (together
with I/O and the other holders distributing their securities through the
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter(s) selected for the underwriting by I/O.  If the managing
underwriter(s) determines that marketing factors require a limitation of the
number of shares to be underwritten, the managing underwriter(s) may limit some
or all of the Registrable Securities that may be included in the registration
and underwriting as follows: the number of Registrable Securities that may be
included in the registration and underwriting by the Stockholder shall be
determined by multiplying the number of shares of Registrable Securities of all
selling stockholders of I/O which the managing underwriter(s) is willing to
include in the registration and underwriting, times a fraction, the numerator of
which is the number of Registrable Securities requested to be included in the
registration and underwriting by the Stockholder, and the denominator of which
is the total number of Registrable Securities which all selling stockholders of
I/O have requested to have included in the registration and underwriting.  I/O
may round the number of shares allocable to any such person to the nearest 100
shares.

3.   MISCELLANEOUS.

shall be entitled to the notice provided in Section 2.1 and the piggyback rights
provided in Section 2, including piggyback rights upon the registration of
Registrable Securities as a result of a Demand Registration pursuant to Section
2.2.  The rights and provisions of this Agreement shall terminate on the
earliest to occur of (i) such time as the Stockholder remains an "affiliate" of
the Company under Rule 144 and can sell its remaining Registrable Securities
under Rule 144 within any three (3) month period or (ii) such time as the
Stockholder ceases to be an "affiliate" of the Company under Rule 144 and all of
its Registrable Securities may be sold pursuant to
