5.    TERMS, CONDITIONS AND FORMS OF OPTIONS

      Each option granted under the Plan shall be evidenced by a written
agreement in such form as the Board of Directors shall from time to time
approve, which agreements shall comply with and be subject to the following
terms and conditions:

      (a) Option Grant Dates. Each eligible director will automatically receive
an option to purchase 15,000 thousand shares of Common Stock at the commencement
of such director's three (3) year term. All options granted under the Plan will
be immediately vest and become exercisable at the rate of one thirty-sixth
(1/36) per full month of service from the date of grant. For directors elected
to less than a three (3) year term, such directors shall receive an option to
purchase five thousand (5,000) shares per year to be served as a director, with
vesting pro rated on a monthly basis. A director joining the Board of Directors
at any time other than the annual meeting of the Company's stockholders shall
receive an option that is reduced, pro rata, based on the time elapsed since the
most recent annual stockholders meeting.

      (b) Option Exercise Price. The option exercise price per share for each
option granted under the Plan shall be equal to: (i) if the Common Stock is then
traded on the over-the-counter market, the average of the Closing bid and ask
prices for the shares of Common Stock in such over-the-counter market for the
last preceding date on which there was a sale of such Common Stock in such
market; (ii) if the Common Stock is then listed on a national securities
exchange, the closing sales price per share for the last preceding date on which
there was a sale of such Common Stock on such exchange; or (iii) if, on the
relevant date, the Common Stock is not publicly traded or reported as described
in (i) or (ii), the value determined in good faith by the Board of Directors.

      (c) Options Non-Transferable. Each option granted under the Plan by its
terms shall not be transferable by the optionee otherwise than by will, or by
the laws of descent and distribution, and shall be exercised during the lifetime
of the optionee only by him. No option or interest therein may be transferred,
assigned, pledged or hypothecated by the optionee during his lifetime, whether
by operation of law or otherwise, or be made subject to execution, attachment or
similar process.

      (d) Exercise Period. Except as otherwise provided in the Plan, each option
may be exercised fully on the date of grant of such option, provided that,
subject to the provisions of Section 5(e), no option may be exercised more than
ninety (90) days after the optionee ceases to serve as a director of the
Company. No option shall be exercisable after the expiration of ten (10) years
from the date of grant or prior to approval of the Plan by the stockholders of
the Company, whichever is earlier.

      (e) Exercise Period Upon Disability or Death. Notwithstanding the

                                       2
<PAGE>   3
provisions of Section 5(d), any option granted under the Plan:

            (i) may be exercised in full by an optionee who becomes disabled
(within the meaning of Section 22(e) (3) of the Code or any successor provision
thereto) while serving as a director of the Company; or (ii) may be exercised

            (x) in full upon the death of an optionee while serving as a
director of the Company, or

            (y) to the extent then exercisable upon the death of an optionee
within ninety (90) days of ceasing to serve as a director of the Company,

by the person to whom it is transferred by will, by the laws of descent and
distribution, or by written notice filed pursuant to Section 5(h);

in each such case within six months (or such longer period as may be determined
by the Board of Directors in its sole discretion) after the date the optionee
ceases to be such a director; provided, that in no option shall be exercisable
after the expiration of ten (10) years from the date of grant.

      (f) Exercise Procedure. Options may be exercised only by written notice to
the Company at its principal office accompanied by payment of the full
consideration for the shares as to which they are exercised.

      (g) Payment of Purchase Price. Options granted under the Plan may provide
for the payment of the exercise price (i) by delivery of cash (or cash
equivalent) in an amount equal to the exercise price of such options or, (ii) to
the extent provided in the applicable option agreement, by delivery to the
Company of shares of Common Stock then owned by the optionee having a fair
market value equal in amount to the exercise price of the options being
exercised, or (iii) by any combination of such methods of payment. The fair
market value of any shares of Common Stock or other non-cash consideration which
may be delivered upon exercise of an option shall be determined by the Board of
Directors.

      (h) Exercise by Representative Following Death of Director. A director, by
written notice to the Company, may designate one or more persons (and for time
to time change such designation) including his legal representative, who, by
reason of his death, shall acquire the right to exercise all or a portion of the
option. If the person or persons so designated wish to exercise all or a portion
of the option, they must do so within the term of the option as provided herein.
Any exercise by a representative shall be subject to the provisions of the Plan.

      (i) Change of Control.

                                       3
<PAGE>   4
            (i) In the event of a Change of Control of the Company, subject to
the condition set forth in Section 5(i)(ii) below, all restrictions and
conditions applicable to Options then outstanding shall be deemed satisfied, and
such Options shall be deemed to be fully vested, as of the date of the Change of
Control. For purposes of this Plan, a Change in Control shall be deemed to occur
if the persons who were directors of the Company shall cease to constitute a
majority of the Board of the Company in connection with any of the following
transactions: (1) the acquisition by a third person, including a "person" as
defined in Section 13(d)(3) of the Exchange Act, of beneficial ownership (as
defined in Rule 13d-3 under the Exchange Act) directly or indirectly, of
securities of the Company representing fifty percent (50%) or more of the total
number of votes that may be cast for the election of the directors of the
Company; or (2) as the result of, or in connection with, any tender or exchange
offer, merger, consolidation or other business combination, sale of assets, or
any combination of the foregoing transactions.

            (ii) Notwithstanding the occurrence of any Change of Control, an
Option shall only receive the benefit of the removal of restrictions and
accelerated vesting, as provided by Section 5(i)(i) above, if such Option is
held by a director of the Company and such director's service on the Company's
Board of Directors terminates, for any reason, following such Change of Control.

            (iii) In the case of any tender or exchange offer, merger,
consolidation or other business combination or sale of all or substantially all
of the assets of the Company, which does not constitute a Change in Control, or
in the case of a reorganization or liquidation of the Company, the Committee, or
the board of directors of any corporation assuming the obligations of the
Company hereunder shall, as to outstanding Options, (i) make appropriate
provision for the protection of any such outstanding Options by the substitution
on an equitable basis of appropriate stock of the Company or of the merged,
consolidated or otherwise reorganized corporation which will be issuable in
respect of the shares of Company Stock, or (ii) upon written notice to the
Participants, provide that the Company or the merged, consolidated or otherwise
reorganized corporation shall have the right, upon the effective date of any
such merger, consolidation, sale of assets or reorganization, to purchase all
Options held by each Participant as to which restrictions have not lapsed as of
that date at an amount equal to the aggregate fair market value on such date of
the shares, such amount to be paid in cash or, if stock of the merged,
consolidated or otherwise reorganized corporation is issuable in respect of the
shares of the Common Stock of the Company, then, in the discretion of the
Committee, in stock of such merged, consolidated or otherwise reorganized
corporation equal in fair market value to the aforesaid amount. In any such case
the Committee shall, in good faith, determine fair market value. The Committee
may, in its discretion, advance the lapse of restrictions and conditions
applicable to Options outstanding as of the date of the merger, consolidation,
sale of assets or reorganization.

                                       4

6.    ASSIGNMENTS

      The rights and benefits under the Plan may not be assigned except for the
designation of a beneficiary as provided in Section 5.

7.    LIMITATION OF RIGHTS

      (a) No Right to Continue as a Director. Neither the Plan, nor the granting
of an option not any other action taken pursuant to the Plan, shall constitute
or be evidence of any agreement or understanding, express or implied, that the
Company will retain a director for any period of time.

      (b) No Stockholders' Right for Options. An optionee shall have no rights
as a stockholder with respect to the shares covered by his options until the
date of the issuance to him of a stock certificate therefor, and no adjustment
will be made for dividends or other rights for which the record date is prior to
the date such certificate is issued.

8.    CHANGES IN CAPITAL STOCK

      (a) If (x) the outstanding shares of Common Stock are increased, decreased
or exchanged for a different number or kind of shares or other securities of the
Company, or (y) additional shares of Common Stock or new or different shares of
Common Stock or other securities of the Company or other non-cash assets are
distributed with respect to such shares or other securities, through or as a
result of any merger, consolidation, sale of all or substantially all of the
assets of the Company, reorganization, recapitalization, reclassification, stock
dividend, stock split, reverse stock split or other similar transaction with
respect to such shares or other securities, an appropriate and proportionate
adjustment shall be made in (i) the maximum number and kind of shares reserved
for issuance under the Plan, and (ii) the number and kind of shares or other
securities subject to any then outstanding options under the Plan, and (iii) the
price for each share subject to any then outstanding options under the Plan
without changing the aggregate purchase price for each share subject to any then
outstanding options under the Plan, without changing the aggregate purchase
price as to which such options remain exercisable. No fractional shares will be
issued under the Plan on account of any such adjustments. Notwithstanding the
foregoing, no adjustment shall be made pursuant to this Section 8 if such
adjustment would cause the Plan to fail to comply with Rule 16b-3 or any
successor rule promulgated pursuant to Section 16 of the Securities Exchange Act
of 1934.

      (b) In the event that the Company is merged or consolidated into or with
another corporation (in which consolidation or merger, the stockholders of the
Company

                                       5
<PAGE>   6
receive distributions of cash or securities of another issuer as a result
thereof), or in the event that all or substantially all of the assets of the
Company are acquired by any other person or entity, or in the event of a
reorganization or liquidation of the Company, the Board of Directors of the
Company, or the Board of Directors of any corporation assuming the obligations
of the Company, shall, as to outstanding options, take one or more of the
following actions; (i) provide that such options shall be assumed, or equivalent
options shall be substituted, by the acquiring or succeeding corporation (or an
affiliate thereof), (ii) upon written notice to the optionees, provide that all
unexercised options will terminate immediately prior to the consummation of such
transaction unless exercised by the optionee within a specified period following
the date of such notice, or (iii) if, under the terms of a merger transaction,
holders of the Common Stock of the Company will receive upon consummation
thereof a cash payment for each share surrendered in the merger (the "Merger
Price"), make or provide for a cash payment to the optionees equal to the
difference between (A) the Merger Price times the number of shares of Common
Stock subject to such outstanding options (to the extent then exercisable at
prices not in excess of the Merger Price) and (B) the aggregate exercise price
of all such outstanding options in exchange for the termination of such options.

9.    AMENDMENT OF THE PLAN

      The Board of Directors may suspend or discontinue the Plan or review or
amend it in any respect whatsoever; provided, however that without approval of
the stockholders of the Company no revision or amendment shall change the number
of shares subject to the Plan or the number of shares issuable to any director
of the Company under the Plan (except as provided in Section 8), change the
designation of the class of any directors eligible to receive options, or
materially increase the benefits accruing to participants under the Plan. The
Plan may not be amended more than once in any six-month period.

10.   WITHHOLDING

      Prior to issuance of shares of Common Stock upon exercise of an Option,
the Optionee shall pay or make adequate provision for any federal or local taxes
or any kind required by law to be withheld by the Company with respect to any
shares issued upon exercise of options under the Plan.

11.   EFFECTIVE DATE AND DURATION OF THE PLAN

      (a) Effective Date. The Plan shall become effective when adopted by the
Board of Directors and approved by the Company's stockholders. Amendments to the
Plan not requiring stockholder approval shall become effective when adopted by
the Board of Directors; amendments requiring stockholder approval shall become
effective when adopted by the Board of Directors, but no option granted after
the date of such amendment shall become exercisable (to the extent that such
amendment to the Plan was

                                       6
<PAGE>   7
required to enable the Company to grant such option to a particular optionee)
unless and until such amendment shall have been approved by the Company's
stockholders. If such stockholder approval is not obtained within twelve months
of the Board's adoption of such amendment, any options granted on or after the
date of such amendment shall terminate to the extent that such amendment to the
Plan was required to enable the Company to grant such option to a particular
optionee.

      (b) Termination. Unless sooner terminated in accordance with Section 9,
the Plan shall terminate upon the close of business on the day next preceding
the tenth anniversary of the date of its adoption by the Board of Directors.

conditions of Rule 16b-3 or its successor promulgated pursuant to Section 16 of
the Securities Exchange Act of 1934. To the extent any provision of the Plan or

it shall be deemed null and void, to the extent permitted by law and deemed

Transpro, Inc.

         Re:      Forbearance Agreement

Ladies and Gentlemen:

         Reference is hereby made to the Revolving Credit Agreement dated as of
July 30, 1998 (as amended and in effect from time to time, the "Credit
Agreement") by and among (a) TRANSPRO, INC., a Delaware corporation (the
"Parent"), ALLEN HEAT TRANSFER PRODUCTS, INC., a Delaware corporation ("AHTP"),
AHTP II, INC., a Delaware corporation ("AHTP II"), EVAP, INC. (f/k/a EI
Acquisition Corp.), a Texas corporation ("EVAP" and collectively with Parent,
AHTP and AHTP II, the "Original Borrowers" and along with GO/DAN INDUSTRIES,
INC., a Delaware corporation ("GDI"), and A/C PLUS, INC., a Texas corporation
("AC"), collectively, the "Borrowers"), (b) FLEET NATIONAL BANK (f/k/a
BankBoston, N.A.), a national banking association, and the other lending
institutions listed on Schedule 1 of the Credit Agreement (collectively, the
"Banks") and (c) FLEET NATIONAL BANK, as agent (the "Agent") for the Banks.

         The Borrowers acknowledge that the Borrowers are in default of certain
of the financial covenants contained in Sections 10.1 and 10.2 of the Credit
Agreement for the period ended June 30, 2000 and the period ended September 30,
2000 (the "Specified Defaults"). The Borrowers acknowledge and agree that the
Agent and the Banks have not waived any of the Specified Defaults. The Borrowers
also acknowledge and agree that as a result of the Specified Defaults the Banks
have no further commitment to lend to the Borrowers and the Banks are entitled
to proceed to enforce any and all of their rights and remedies under the terms
of the Loan Documents. The Borrowers previously requested that the Agent and the
Banks forbear from exercising their rights and remedies under the Loan Documents
(a) until the "Forbearance Termination Date" as defined in that certain
Forbearance Agreement dated as of August 18, 2000, by and among the Borrowers,
the Agent and the Banks (the "First Forbearance Agreement") under the terms and
conditions set forth therein, and (b) until the "Second Forbearance Termination
Date" as defined in that certain Forbearance Agreement dated as of September 29,
2000, by and among the Borrowers, the Agent and the Banks (the "Second
Forbearance Agreement") under the terms and conditions set forth therein, and
the Agent and the Banks agreed to forbear from exercising their rights and
remedies under the Loan Documents as set forth in the First Forbearance
Agreement and the Second Forbearance Agreement. The Borrowers have now requested
that the Agent and the Banks further forbear from exercising their rights and
remedies under the Loan Documents until the Third
<PAGE>   2
                                      -2-

Forbearance Termination Date (as hereinafter defined) under the following terms
and conditions:

         SECTION 1. DEFINITIONS. All capitalized terms used herein without
definition that are defined in the Credit Agreement, as amended and in effect on
the date hereof, shall have the same meanings herein as therein. All accounting
terms used herein and not otherwise defined shall be used in accordance with
generally accepted accounting principles.

         SECTION 2. RATIFICATION OF EXISTING AGREEMENTS. The Borrowers hereby
ratify and confirm in all respects all of the Obligations, except as otherwise
expressly modified in this Agreement upon the terms set forth herein. In
addition, by execution of this Agreement, the Borrowers represent and warrant
that as of the date hereof, no claim or counterclaim, right of setoff or defense
of any kind exists or is outstanding with respect to the Obligations. The
Borrowers further agree that, to the extent any such claim, counterclaim, right
of setoff or defense of any kind exists, the Borrowers hereby waive and release
each and all of them in consideration for the Banks entering into this
Agreement. The Borrowers acknowledge that, in entering into this Agreement, the
Agent and the Banks have relied on the representations, warranties and waivers
contained in this Section 2.

         SECTION 3. REPRESENTATIONS AND WARRANTIES. The Borrowers have adequate
corporate power and authority to execute and deliver this Agreement and to
perform their obligations hereunder. This Agreement has been duly authorized,
executed and delivered by the Borrowers and does not contravene any law, rule or
regulation, or any judgment, order or decree, applicable to any of the Borrowers
or any of the terms of the Borrowers' charter documents, by-laws or other
governing document or any indenture, agreement or undertaking to which any of
the Borrowers is a party. The obligations of the Borrowers under this Agreement
and the Loan Documents constitute their legal, valid and binding obligations
enforceable against them in accordance with their respective terms. All of the
representations and warranties made by or on behalf of the Borrowers in the Loan
Documents are true and correct on the date hereof as if made on and as of the
date hereof, except for those matters disclosed herein.

         SECTION 4. FORBEARANCE OBLIGATIONS. Subject to the conditions set forth
in Section 5 hereof, the Agent and the Banks agree to forbear from enforcing any
of their rights and remedies under the Loan Documents for the purpose of seeking
payment of any of the Obligations (including, without limitation, any act with
respect to any collateral now or hereafter securing payment of any Obligations
or any setoff or any other application of funds of the Borrowers now or
hereafter on deposit with or otherwise controlled by the Agent and the Banks)
until that date (the "Third Forbearance Termination Date") which is the earliest
to occur of (a) the Borrowers' failure to comply with any of the terms and
conditions of this Agreement, including any of the undertakings set forth in
Sections 5 and 6 hereof, (b) an Event of Default (other than the Specified
Defaults), (c) the lesser of the Borrowing Base and the Total Commitment at any
time failing to exceed the sum of the outstanding amount of the Loans, the
Maximum Drawing Amount and all Unpaid Reimbursement Obligations by $20,000,000,
(d) the sum of the outstanding amount of the Loans, the Maximum Drawing Amount
and all Unpaid Reimbursement Obligations at any time being greater than
$52,000,000 for the period from the effective date of this Agreement
<PAGE>   3
                                      -3-

through December 20, 2000, and (e) December 20, 2000. The period from the
effective date of this Agreement through the Third Forbearance Termination Date
is referred to herein as the "Limited Forbearance Period". Except as expressly
provided above in this Section 4, the Agent and the Banks reserve the right to
exercise all of their rights and remedies under the Loan Documents. Upon the
Third Forbearance Termination Date, the Agent and the Banks shall be free in
their sole and absolute discretion to proceed to enforce any or all of their
rights and remedies under or in respect of the Loan Documents and applicable
law, including without limitation, those credit termination, acceleration,
enforcement and other rights and remedies arising by virtue of the occurrence of
the Specified Defaults. In addition, the parties hereto hereby acknowledge and
agree that time is of the essence in this Agreement. The parties intend and
understand that any failure scrupulously to observe the timing requirements of
this Agreement, including, without limitation, any late payment made hereunder,
will be a material breach giving rise to the remedies set forth herein. The
imposition of such remedies shall not be deemed a penalty, and is of the essence
of the parties' bargain.

         SECTION 5. CONDITIONS TO EFFECTIVENESS. This Agreement shall become
effective upon satisfaction of the following conditions on or prior to November
15, 2000:

                  (a) The Agent, the Banks and the Borrowers shall have executed
         and delivered counterparts of this Agreement to the Agent; and

                  (b) The Borrowers shall have paid to the Agent for the pro
         rata account of the Banks $52,000.

         SECTION 6. COVENANTS AND AGREEMENTS. Without any prejudice or
impairment whatsoever to any of the rights and remedies of the Agent and the
Banks contained in any of the Loan Documents or in any agreement, document or
instrument executed in connection therewith, the Borrowers covenant and agree
with the Agent and the Banks as follows:

                  (a) DISCRETIONARY LENDING. Though they have no obligation to
         do so, during the Limited Forbearance Period the Banks shall continue
         to make advances to the Borrowers provided that all conditions
         precedent thereto, other than the non-existence of the Specified
         Defaults, shall be satisfied.

                  (b) INTEREST. The Borrowers acknowledge and agree that during
         the Limited Forbearance Period interest shall accrue at the rate of
         interest set forth in the Credit Agreement plus an additional 1/2% per
         annum. Interest shall be payable as set forth in the Credit Agreement.
         Nothing contained herein shall prevent the Agent and the Banks from
         charging the entire default rate of interest contained in Section 5.11
         of the Credit Agreement on or after the Third Forbearance Termination
         Date, retroactive to the date the first Specified Default occurred.

                  (c) COMPLIANCE WITH LOAN DOCUMENTS. The Borrowers will, and
         will cause each of their Subsidiaries to, comply and continue to comply
         with all of the terms, covenants and provisions contained in the Loan
         Documents to which each is a party
<PAGE>   4
                                      -4-

         and any other instruments evidencing or creating any of the Obligations
         except as such terms, covenants and provisions are expressly modified
         in this Section 6.

                  (d) REFINANCING. The Borrowers jointly and severally agree to
         deliver to the Agent no later than December __, 2000 a binding
         commitment letter from a financial institution, in form and substance
         satisfactory to the Agent, indicating that the Loans shall be repaid no
         later than December 20, 2000.

                  (e) COLLATERAL. The Borrowers and their Subsidiaries shall
         provide to the Agent such additional security agreements and other
         security documents as the Agent may request in order to obtain, perfect
         and preserve a first priority perfected security interest (subject only
         to Permitted Liens) in all existing and after-acquired personal
         property and fixtures of the Borrowers and their Subsidiaries for the
         benefit of the Agent and the Banks. This shall include without
         limitation, a requirement that all cash received by the Borrowers be
         used to pay down the Loans on a daily basis.

                  (f) FURTHER ASSURANCES. The Borrowers shall at any time or
         from time to time execute and deliver such further instruments, and
         take such further action as the Agent may reasonably request, in each
         case further to effect the purposes of this Agreement, the Loan
         Documents and all documents, agreements and instruments executed in
