percent  (50%)  or more of the  Stockholder  Shares  then  owned  by  Paramount,
Paramount shall have the right, exercisable upon twenty (20) days' prior written
notice to the Other Stockholders,  to require the Other Stockholders to sell all
of their  Stockholder  Shares to the proposed  purchaser,  on the same terms and
conditions as govern the proposed Transfer by Paramount.

            (c) Tag Along  Rights.  Subject  to Section  2(d),  at least 15 days
prior to any Transfer by Paramount of Paramount  Shares  constituting  more than
25% of the issued and outstanding Stockholder Shares,  Paramount shall deliver a

transferee(s)  and the terms and  conditions  of the  Transfer.  Enhance and the

delivering written notice to Paramount within 10 days after delivery of the Sale
Notice. If Enhance or any Other Stockholders have elected to participate in such
Transfer,  each of  Paramount,  Enhance  and such  Other  Stockholders  shall be
entitled  to sell in the  contemplated  Transfer,  with  respect to each type of
securities being  Transferred,  for the same consideration and on the same terms
(provided that adequate  provision  shall be made to account for any exercise or
conversion  prices  payable  by any  Stockholder  with  respect to any rights to
acquire Stockholder Shares), a number of Stockholder Shares equal to the product
of (i) the  quotient  determined  by dividing the number of  Stockholder  Shares
owned by such Stockholder by the aggregate number of Stockholder Shares owned by
the Stockholders  participating in such Transfer,  and (ii) the aggregate number
of Stockholder Shares to be sold in the contemplated Transfer.

            (d)  Permitted  Transfers.  The  restrictions  contained in Sections
2(a),  2(b) and 2(c) shall not apply with respect to any Transfer of Stockholder
Shares by any Stockholder (i) in the case of an individual Stockholder, pursuant

Stockholder's  Family  Group,  (ii) in the  case of an  entity,  (x)  among  its
Affiliates,  members,  shareholders,  partners  or  employees  or other  Persons
approved  by a majority  of the voting  power of the Board in the  Board's  sole
discretion,  but  excluding  in all cases under this  clause  (ii) any  Transfer
constituting a distribution that would require registration under the Securities
Act, or (y) to any  employee or director of the Company or any  Affiliate of the
Company;  provided,  that the  restrictions  contained in Sections 2(a) and 2(b)
shall  continue  to be  applicable  to such  Stockholder  Shares  after any such
Transfer;  and provided further, that the transferees of such Stockholder Shares
shall have  agreed in writing to be bound by the  provisions  of this  Agreement
which  affect the  Stockholder  Shares so  transferred  by  executing  a Joinder
Agreement  in  the  form  substantially   attached  hereto  as  Exhibit  A.  All
transferees  permitted  under this  Section  2(d) are  collectively  referred to
herein as "Permitted Transferees."

            (e) Termination of  Restrictions.  The rights and  restrictions  set
forth in this Section 2 (other than the rights set forth in Section 2(b),  which

until the date that is twelve (12) months  after the  consummation  of a Trading
Event.

            3. Sale of the Company.

            (a) In the event of an  Approved  Sale,  each  Stockholder  will (i)
consent to and raise no  objections  against  the  Approved  Sale or the process
pursuant to which the Approved  Sale was  arranged,  (ii) waive any  dissenter's
rights and other similar rights, and (iii) if the Approved Sale is structured as
a sale of securities, each Stockholder will agree to sell its Stockholder Shares
(and any other capital stock of the Company) on the terms and  conditions of the
Approved Sale. Each Stockholder will take all necessary and desirable actions as
directed by the Board in connection with the  consummation of any Approved Sale,
including without  limitation  executing the applicable  purchase  agreement and
granting identical indemnification rights (pro rata based upon the consideration
received pursuant to the Approved Sale and not joint and several).

            (b) The  obligations  of each  Stockholder  under this Section 3 are
subject to the satisfaction of the following  conditions:  (i) upon consummation
of an  Approved  Sale,  each  Stockholder  shall  receive  in  exchange  for the
Stockholder  Shares (and any other  capital  stock of the Company)  held by such
Stockholder  the same portion of the aggregate  consideration  from such sale or
exchange  that  such   Stockholder   would  have  received  if  such   aggregate
consideration  had been  distributed  by the  Company  in  complete  liquidation
pursuant  to  the  rights  and  preferences  set  forth  in the  Certificate  of
Incorporation,  (ii) if the holders of a class or series of capital stock of the
Company are given an option as to the form of consideration to be received,  all
holders of shares of such class or series of  capital  stock  shall be given the
same  option,  and (iii) each  holder of then  currently  exercisable  rights to
acquire Stockholder Shares shall be given an opportunity to exercise such rights
prior to the consummation of the Approved Sale and participate in such sale as a
holder of such Stockholder Shares.

            (c) All Stockholders  will bear their pro rata share (based upon the
consideration received pursuant to the Approved Sale) of the reasonable costs of
an Approved  Sale to the extent such costs are  incurred  for the benefit of all
Stockholders  and are not otherwise paid by the Company or the acquiring  party.
Costs incurred by any Stockholder on its own behalf will not be considered costs
of the transaction hereunder.

            4. Registrations.

            (a) Piggyback Registration.

                                       5
<PAGE>

                  (i) Whenever  securities  of the Company are to be  registered
under the  Securities Act and the  registration  form to be used may be used for
the registration of Stockholder Shares (a "Piggyback Registration"), the Company
will give prompt  written  notice to Paramount  and Enhance of its  intention to
effect such a registration  and will,  subject to the  limitations  set forth in
this Section 4, include in such  registration  all Stockholder  Shares,  if any,
with respect to which the Company has received a written  request from Paramount
or Enhance for  inclusion  therein  within  twenty (20) days after the Company's
notice has been given  pursuant to the  provisions  of this Section 4;  provided
that such form of registration is then available for sales of shares.

                  (ii) If a Piggyback  Registration  is an  underwritten  public
offering of Common Stock of the Company, and the managing  underwriter(s) advise
the Company  that in their  opinion  the number of  securities  requested  to be
included  in the  registration  exceeds  the  number  which  can be sold in such
offering  without  having  an  adverse  effect  on  the  marketability  of  such
securities,  the  Company  will  include in such  registration  (A)  first,  the
securities the Company proposes to sell, and (B) second,  the Stockholder Shares
requested to be included in such registration by Paramount,  and the Stockholder
Shares  requested  to be  included  in such  registration  by Enhance  (all such
Stockholder  Shares set forth in this subsection (B) and (C) being  collectively
referred  to as the  "Secondary  Shares")  pro rata as between  the  Stockholder
Shares owned by Paramount and Enhance based on the number of Stockholder  Shares
then owned by such  Persons,  which in the opinion of such  underwriters  can be
sold without  having an adverse  effect on the  marketability  of such Secondary
Shares.

                  (iii) All registration expenses of any Piggyback Registration,
including the reasonable legal fees and expenses, up to a maximum of $20,000, of
a single law firm representing all Persons holding  Secondary  Shares,  shall be
borne by the Company.

                  (iv) In the event that a distribution of securities covered by
a  Piggyback  Registration  is to be  underwritten,  then  any  distribution  of
Stockholder  Shares  shall  be  underwritten  by the same  underwriters  who are
underwriting  the  distribution  of the  securities  on behalf of the Company or
Paramount,  and,  if  Enhance's  Stockholder  Shares are to be  included in such
distribution,  then Enhance shall enter into an underwriting agreement with such
underwriters on terms reasonably requested by such underwriters.

                  (v)  The  Company  may  withdraw  any  registration  statement
relating to a Piggyback  Registration  referred  to in Section  4(a)(i)  without
thereby incurring any liability to Paramount or Enhance.

Act of all or any portion of his or  Paramount's  Stockholder  Shares (A) on not
more than three (3) occasions ("Long-Form Registrations") unless Form S-3 or any
similar short-form registration is then available for such registration, and (B)
on Form S-3 or any similar short-form registration ("Short-Form  Registrations")
if,  and  only  if,  such  form of  registration  is  then  available  for  such
registration.  All  registrations  requested  pursuant to this  Section 4(b) are
referred  to  herein  as  "Demand  Registrations."  Each  request  for a  Demand
Registration   shall  specify  the  approximate  number  of  Stockholder  Shares
requested to be  registered.  Upon  Company's  receipt of a request for a Demand
Registration,  Company will promptly give written notice of the proposed  Demand
Registration  to  Enhance  and the  Other  Stockholders  and,  expeditiously  as
possible,  effect such Demand  Registration and all such related  qualifications
and  compliances  as may be requested and as would permit or facilitate the sale
and  distribution  of all  Stockholder  Shares as are specified in such request.
After Company has become subject to the reporting requirements of the Securities
Exchange  Act,   Company   shall  use  its  best  efforts  to  make   Short-Form
Registrations  available for the sale of Stockholder Shares.  Rosenwald shall be
entitled to request an unlimited  number of Short-Form  Registrations;  provided
that such form of  registration  is then available for sales of shares.  Company
shall  pay  all   Registration   Expenses  in  connection   with  the  Long-Form
Registrations and up to two Short-Form Registrations in any twelve-month period,
including with respect to each such Demand  Registration,  the reasonable  legal
fees and expenses, up to a maximum of $20,000, of a single law firm representing
all Persons holding  Stockholder  Shares  included in such Demand  Registration.
Company shall not be obligated to effect any Demand Registration within 180 days
after  the  effective  date of a  previous  Demand  Registration  or a  previous
registration  in which the holders of  Stockholder  Shares were given  piggyback
rights  pursuant  to Section  4(a).  Parent may  postpone  for up to 90 days the
filing  or  the   effectiveness  of  a  registration   statement  for  a  Demand
Registration if Company's  board of directors  determines in its reasonable good
faith  judgment that such Demand  Registration  would  reasonably be expected to
have a material  adverse  effect on any proposal or plan by Company to engage in
any acquisition of assets (other than in the ordinary course of business) or any
merger,  consolidation,  tender offer,  reorganization  or similar  transaction;
provided,  however, that Company may not exercise its right under this paragraph
more than twice in any 12-month period.

                  (ii) The Company shall have the right to select the investment
banker(s) and  manager(s) to administer the offering in an  underwritten  Demand
Registration;  provided  that  such  investment  banker(s)  and  manager(s)  are
reasonably  acceptable to Company.  In connection with each underwritten  Demand
Registration,  Company agrees to enter into such customary agreements (including
underwriting  agreements)  as the  managing  underwriter  selected in the manner
herein  provided may request in such form and containing  such provisions as are
customary in the  securities  business  for such an  arrangement  between  major
underwriters  and companies of Company's size and investment  stature;  provided
that such agreement  shall not contain any such provision  applicable to Company
which is inconsistent with the provisions hereof.

            (c)  Rule  144.  At any time and  from  time to time  after  (A) the
Company  registers  a class of  securities  under  Section 12 of the  Securities
Exchange Act, or (B) the  expiration of ninety (90) days  following the close of
business on the earlier of such date as the Company  commences  to file  reports
under  Section 13 or Section  15(d) of the  Securities  Exchange  Act, then upon
receipt of a written request of Enhance,  stating that Enhance  proposes to sell
securities in compliance with Rule 144 of the  Commission,  the Company will (Y)
forthwith  furnish to Paramount  and Enhance a written  statement of  compliance
with the filing requirements of the Commission under Section 13 or Section 15 of
the Securities  Act and other steps it has taken to enable  Paramount or Enhance
to make sale  pursuant to Rule 144 as such rule may be amended from time to time
and (Z) use its commercially reasonable efforts to make available to the public,
Paramount and Enhance such  information  as will enable the holder to make sales
pursuant to Rule 144.  The Company  shall use its best  efforts to (1) cause any
registration  statement  filed pursuant to Sections 4(a) or (b) herein to become
effective,  and (2) cause such registration  statement to remain effective until
the earliest to occur of (AA) such date as the  Stockholders of such Stockholder
Shares (the "Selling Holders") have completed the distribution  described in the
registration  statement and (BB) such time that all of such  Stockholder  Shares
are no longer, by reason of Rule 144(k) under the Act, required to be registered
for the sale  thereof by such  Stockholders.  The Company will also use its best
efforts to, during the period that such registration statement is required to be
maintained  hereunder,  file  such  post-effective  amendments  and  supplements
thereto as may be required by the Securities  Act and the rules and  regulations
thereunder  or otherwise  to ensure that such  registration  statement  does not
contain any untrue  statement of material  fact or omit to state a fact required
to be stated therein or necessary to make the statements  contained therein,  in
light of the circumstances under which they are made, not misleading;  provided,
however,  that if  applicable  rules  under the  Securities  Act  governing  the
obligation  to file a  post-effective  amendment  permits,  in lieu of  filing a
post-effective  amendment that (I) includes any  prospectus  required by Section
10(a)(3) of the Securities  Act or (II) reflects facts or events  representing a
material or fundamental change in the information set forth in such registration
statement,  the Company may incorporate by reference  information required to be
included in (I) and (II) above to the extent such  information  is  contained in
periodic  reports  filed  pursuant to Section 13 or 15(d) of the Exchange Act in
such registration statement.  The Company shall keep such registration effective
until the Stockholder  Shares subject to such registration are saleable pursuant
to Rule  144(k);  provided,  however,  that the  Company  may not  suspend  such
registration under this Section 4(c) unless required by law.

            (d) Notice by Company.  The  Company  agrees to give  Paramount  and
Enhance prompt written notice of its intention to register any of its securities
under the  Securities  Act.  Paramount  and Enhance each agree to provide to the
Company  in  writing  any  information  reasonably  deemed by the  Company to be
required to be included  with respect to  Paramount or Enhance,  as the case may
be, in any  registration  statement  prepared  in  connection  with a  Piggyback
Registration pursuant to Section 4(a).

            (e) Lock-up. Provided that the Company's officers,  directors and 5%
shareholders  agree to an  equivalent  lockup,  Enhance  agrees that without the
written  consent of the  Company it will not,  for a period of 90 days,  or such
longer  period  of  time  as  agreed  to  by  the  officers,  directors  and  5%
shareholders  of  the  Company   following  the  effective  date  of  the  first
registration  statement  for  the  offering  of  Stockholder  Shares  under  the
Securities Act directly or indirectly  sell, offer to sell, grant any option for
the sale  of,  or  otherwise  dispose  of any  Stockholder  Share or  securities
convertible into Stockholder Shares,  except (i) for the Stockholder Shares sold
pursuant  to such  registration  statement,  and  (ii)  transfers  to  Permitted
Transferees  (each of which shall have furnished to the Company and the managing
underwriter their written consent to be bound by this Agreement,  including this
clause (ix) or, if requested by the managing  underwriter,  enter into a lock-up
agreement  containing terms which are materially  similar to the terms set forth

<PAGE>

      The  Company  shall  imprint  such  legend  on   certificates   evidencing
Stockholder  Shares  outstanding prior to the date hereof.  The legend set forth
above shall be removed from the  certificates  evidencing any shares which cease

            6.  Transfers in Violation of  Agreement.  Any Transfer or attempted
      Transfer of any  Stockholder  Shares in violation of any provision of this
      Agreement  shall be null and void,  and the Company  shall not record such
      Transfer  on  its  books  or  treat  any  purported   transferee  of  such
      Stockholder Shares as the owner of such shares for any purpose.

            7. Transfer of Stockholder Shares.

            (a) Stockholder  Shares are transferable only pursuant to (i) public
offerings registered under the Securities Act, (ii) subject to the provisions of
Section 2 and  Section 3 above,  Rule 144 or Rule 144A (or any  similar  rule or
rules then in effect) of the SEC if such rule is  available,  (iii) an effective
registration  statement  filed in accordance  with the Securities  Act, and (iv)
subject to Section 2, Section 3 and Section 7(b),  any other  legally  available
means of Transfer.

            (b) In connection with the Transfer of any Stockholder  Shares other
than a Transfer  described in clause (i), (ii) or (iii) of Section 7(a) above or
a Transfer to a Permitted  Transferee,  the holder thereof shall deliver written
notice to the Company  describing in reasonable  detail the Transfer or proposed
Transfer,  together  with an  opinion of counsel  reasonably  acceptable  to the
Company to the effect that such Transfer of  Stockholder  Shares may be effected
without  registration  of such  Stockholder  Shares under the Securities Act. No
Transfer or issuance of any  Stockholder  Shares shall be  permitted  unless and
until the prospective  transferee agrees to become a party to this Agreement and
be bound by all the terms and  conditions  hereof by executing and delivering to
the Company,  a joinder to this Agreement in the form attached hereto as Exhibit
A.

            (c) Upon the request of a holder of Stockholder  Shares, the Company
shall  promptly  supply  to  such  Person  or its  prospective  transferees  all
information  regarding the Company required to be delivered in connection with a
Transfer  pursuant to Rule 144A (or any similar rule or rules then in effect) of
the SEC.

            8. Amendment and Waiver.  Except as otherwise  provided  herein,  no
      modification, amendment or waiver of any provision of this Agreement shall
      be  effective  against  the  Company  or  the  Stockholders   unless  such
      modification,  amendment  or waiver is  approved in writing by the Company
      and  the  holders  of  not  less  than  51%  of  the  Stockholder  Shares,
      respectively.   Notwithstanding   anything   to  the   contrary,   (i)  no
      modification, amendment or waiver of any provision specifically applicable
      to Enhance shall be effective  against  Enhance unless approved in writing
      by Enhance, and (ii) no modification, amendment or waiver of any provision
      that materially and adversely affects any particular  Stockholder compared
      to its  effect on each  Other  Stockholder  hereunder  shall be  effective
      against such Stockholder  unless approved in writing by such  Stockholder.
      The  failure  of any  party  to  enforce  any of the  provisions  of  this
      Agreement  shall in no way be construed as a waiver of such provisions and
      shall not affect the right of such party  thereafter  to enforce  each and
      every provision of this Agreement in accordance with its terms.

            9. Severability. Whenever possible, each provision of this Agreement
      shall be  interpreted  in such manner as to be  effective  and valid under
      applicable  law,  but if any  provision  of this  Agreement  is held to be
      invalid,  illegal or unenforceable in any respect under any applicable law
      or   rule   in  any   jurisdiction,   such   invalidity,   illegality   or
      unenforceability  shall  not  affect  any  other  provision  or any  other
      jurisdiction, but this Agreement shall be reformed, construed and enforced
      in  such  jurisdiction  as  if  such  invalid,  illegal  or  unenforceable
      provision had never been contained herein.

            10.  Entire  Agreement.  Except  as  otherwise  expressly  set forth
      herein,  this document  embodies the complete  agreement and understanding
      among the parties  hereto with  respect to the subject  matter  hereof and
      supersede   and   preempt   any  prior   understandings,   agreements   or
      representations  by or among the parties,  written or oral, which may have
      related to the subject matter hereof in any way.

            11.  Successors and Assigns.  Except as otherwise  provided  herein,
      this  Agreement  shall bind and inure to the benefit of and be enforceable
      by the Company and its successors and assigns and the Stockholders and any
      subsequent  holders of  Stockholder  Shares and the  respective  permitted
      successors  and assigns of each of them, so long as they hold  Stockholder
      Shares.

            12.  Counterparts.  This  Agreement  may  be  executed  in  separate
      counterparts  each of which  shall be an  original  and all of which taken
      together shall constitute one and the same agreement.

            13. Remedies.  The parties hereto shall be entitled to enforce their

      any breach of any  provision of this  Agreement  and to exercise all other
      rights  existing in their favor.  The parties hereto agree and acknowledge
      that money  damages  may not be an  adequate  remedy for any breach of the
      provisions  of  this  Agreement  and  that  the  Company  may in its  sole
      discretion  apply to any court of law or equity of competent  jurisdiction
      for specific  performance and/or injunctive relief (without posting a bond
      or other  security)  in order to enforce or prevent any  violation  of the
      provisions of this Agreement.

Re:    1997 Long-Term Incentive Plan Performance Award -
       Targets for 3-Year Period Ending May 2009

Dear Participant:

The Compensation Committee of the Board of Directors of Worthington Industries,
Inc. (the "Company") has granted to you a Performance Award under the Company's
1997 Long-Term Incentive Plan (the "Plan") on the terms described below. The
Performance Award is designed to provide incentive payouts to certain senior
managers based on the attainment of stated financial performance targets over a
three-year period.

In an effort to focus on both the quantity and quality of earnings, the
Performance Award incorporates both an earnings per share ("EPS") and economic
value added ("EVA") component. EPS targets are for corporate EPS for the fiscal
year ending 2009. EVA targets are for cumulative corporate EVA over the
three-year period ending May 31, 2009. For corporate officers, half of the
possible Performance Award is allocated to the EPS target and half to the EVA
target. For business unit executives, the Performance Award is structured a
little differently; half of the possible Performance Award is allocated to the
same corporate EPS and EVA targets as the corporate officers and half is
allocated to business unit operating income targets.

Your target Performance Awards for the three-year performance period ending May
31, 2009 are: (a) a Cash Award of $______ and (b) a Performance Share Award of
__________ common shares of Worthington Industries, Inc. ("Company Stock"). The
specific performance targets, and the related Cash Award and Performance Share
Award, are set forth below:
                                                               Performance
EPS Targets            2009 Corporate EPS      Cash Award      Share Award
-----------            ------------------      ----------      -----------

    Threshold             $________            $________       _____ shares
    Target                $________            $________       _____ shares
    Maximum               $________            $________       _____ shares

                    Cum 3 Year Corporate
EVA Targets            EVA Ending 2009
-----------            ---------------

    Threshold             $____ million        $________       _____ shares
    Target                $____ million        $________       _____ shares
    Maximum               $____ million        $________       _____ shares

<PAGE>

Performance falling between threshold and maximum will be pro rated on a linear
basis.

No payments will be made if performance falls below threshold. Each of the
performance measures is free standing so that you will be able to earn a pay-out
based upon the achievement of one measure, even if the threshold performance
level is not achieved in the other measure.

Calculation of the Company results and attainment of performance measures will
be made solely by the Compensation Committee based upon the Company's audited
consolidated financial statements. The Compensation Committee has the right to
make changes and adjustments in calculating the performance measures to take
into account unusual or non-recurring events, including, without limitation,
changes in tax and accounting rules and regulations; extraordinary gains and
losses; mergers and acquisitions and purchases or sales of substantial assets;
provided that, if Section 162(m) of the Internal Revenue Code would be
applicable to the pay-out of the Performance Awards hereunder, any such change
or adjustment must be permissible under Section 162(m).

The determination of the attainment of performance objectives and the amount of
the Performance Awards payable will generally be finalized within a reasonable
time after the audit of the applicable consolidated financial statements of the
Company has been completed. Payments will then be made within a reasonable time
after finalization by the Committee, unless there is a need for a delay.

Unless the Committee elects a different form of pay-out, payments of the Cash
Award will be made in cash. Payment of the Performance Share Award will be made
in Company Stock. The Committee may adopt provisions permitting the deferral of
a portion or all of the pay-out into a Deferred Compensation Plan, provided that
a timely deferral election is made. The Company may require payment of, or may
withhold from payments, amounts necessary to meet any federal, state or local
tax withholding requirements.

In general, termination of employment terminates Performance Awards. Termination
of employment for reasons of death, disability or retirement will result in a
pro rata pay-out for performance periods ending within 24 months after
termination based on the number of months of employment completed by you during
the performance period before the effective date of termination. No pay-out will
be made for performance periods ending more than 24 months after termination.
Termination of employment for any other reason, voluntary or involuntary, prior
to the Committee's determination of the attainment of performance objectives and
finalization of the Performance Award amount will result in the forfeiture of
all Performance Awards from the Plan.

The provisions of the Plan are incorporated herein by reference and a copy is
available at your request.

If you have any questions about your Performance Awards, please direct them to
me.

Very truly yours,
