participating agents, brokers or dealers may be deemed to be underwriters as
that term is defined in the Securities Act of 1933, as amended (the "Securities
Act"), and commissions or discounts or any profit realized on the resale of such
securities may be deemed to be underwriting commissions or discounts under the
Securities Act.  The Company, however, understands that the Selling Stockholders
do not admit that they are underwriters within the meaning of the Securities
Act.  The Company will not receive any of the proceeds from the sales of the
securities offered hereby.

     The Company will pay all expenses incurred in connection with this
offering, which are estimated to be approximately $14,000.00.

(1) Former director, executive officer and shareholder of American Business

     Pursuant to that certain Agreement of Merger dated as of August 1, 1994
(the "Merger Agreement"), the Company acquired American Business Computer
Company, a Michigan corporation ("ABCC"), through the merger of a wholly owned
subsidiary of the Company with and into ABCC.  Under the terms of the Merger
Agreement, each of the Selling Stockholders received the Shares listed in the
table above in exchange for shares of capital stock of ABCC owned by such
Selling Stockholder.  The Company agreed to register such shares of Common Stock
pursuant to the Merger Agreement under the Securities Act for resale by the
Selling Stockholders.  The Company will not receive any of the proceeds from the
sale of the Shares by the Selling Stockholders.


                              PLAN OF DISTRIBUTION

     The Shares offered hereby may be sold from time to time to purchasers
directly by any of the Selling Stockholders. Alternatively, the Selling
Stockholders may from time to time offer the Shares through underwriters,
dealers or agents who may receive compensation in the form of underwriting
discounts, concessions or commissions from the Selling Stockholders and/or the
purchasers of the Shares for whom they may act as agent. The Selling
Stockholders and any underwriters, dealers or agents that participate in the
distribution of the Shares may be deemed to be underwriters, and any profit on
the sale of the Shares by them and any discounts, commissions or concessions
received by any such underwriters, dealers or agents might be deemed to be
underwriting discounts and commissions under the Securities Act. The Company,
however, understands that the Selling Stockholders do not admit that they are
underwriters within the meaning of the Securities Act.

     The Shares may be disposed of from time to time in one or more
transactions, by sales of the Shares or the rights thereto, by the writing
of options on the Shares,

                                      -4-
<PAGE>
 
or the granting of pledges thereon, all at fixed offering prices, which may be
changed, or at varying prices determined at the time of sale or at negotiated
prices. The Selling Stockholders may effect these transactions by selling the
Shares to or through broker-dealers or by pledges of the Shares to broker-
dealers who themselves may effect, from time to time, distributions of the
Shares or interests therein. The Company will pay all of the expenses incident
to the offering and sale of the Shares to the public other than underwriting
discounts or commissions, brokers' fees and the fees and expenses of any counsel
to the Selling Stockholders related thereto.

    ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
              ----------------------------------------- 

    Section 145 of the Delaware General Corporation Law empowers a corporation
to indemnify its directors and officers or former directors or officers and to
purchase insurance with respect to liability arising out of their capacity or
status as directors and officers.  Such law provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any other
rights to which the directors and officers may be entitled under a corporation's
Certificate of Incorporation, Bylaws, any agreement or otherwise.

    Article IX of the Company's Certificate of Incorporation, as amended,
provides that, to the fullest extent permitted by the Delaware General
Corporation Law, as the same exists or may hereafter be amended, a director of
the Company shall not be liable to the Company or its stockholders for monetary
damages for breach of fiduciary duty as a director.  Article IX of the Company's
Restated Bylaws provides for indemnification of officers and directors.  In
addition, the Company has entered into Indemnity Agreements with each of its
officers and directors pursuant to which such officers and directors may be
indemnified against losses arising from certain claims, including claims under
the Securities Act, which may be made by reason of their being officers or
directors.

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provisions, the Company has been advised that in the
opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.

    ITEM 17.  UNDERTAKINGS.
              ------------ 

    (a) The undersigned registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
    made, a post-effective amendment to this registration statement:

               (i) To include any prospectus required by section 10(a)(3) of the
          Securities Act;

               (ii) To reflect in the prospectus any facts or events arising
          after the effective date of the registration statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the registration statement;

               (iii)  To include any material information with respect to the
          plan of distribution not previously disclosed in the registration
          statement or any material change to such information in the
          registration statement;

          Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
    apply if the information required to be included in a post-effective
    amendment by those paragraphs is contained in periodic reports filed by the
    registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that
    are incorporated by reference in this registration statement.

          (2) That, for the purpose of determining any liability under the
    Securities Act, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

    (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                                      II-4
<PAGE>
 
    (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

      Re:  Registration Statement on Form S-3 of Sterling Software, Inc.

Ladies and Gentlemen:

     We are acting as counsel for Sterling Software, Inc., a Delaware
corporation (the "Company"), in connection with the registration under the
Securities Act of 1933, as amended (the "Act"), of the offer and sale of up to
306,513 shares of common stock, par value $.10 per share, of the Company (the
"Shares") by certain "Selling Stockholders" (as defined in the above-captioned
registration statement). A registration statement on Form S-3 covering the sale
of the Shares (the "Registration Statement") is expected to be filed under the
Act with the Securities and Exchange Commission (the "Commission") on or about
the date hereof.

     In reaching the conclusions expressed in this opinion, we have examined and
relied upon the original or copies, certified to our satisfaction, of all
documents, certificates and instruments as we have deemed necessary for the
expression of the opinions expressed herein. In making the foregoing
examinations, we have assumed that all signatures on all documents submitted to
us are genuine, that all documents submitted to us as originals are accurate and
complete, and that all documents submitted to us as copies are true, correct
and complete copies of the originals thereof.

     Based solely upon the foregoing and subject to the comments and exceptions
herein stated and limited in all respects to the laws of the State Texas, the
General Corporation Law of the State of Delaware, the laws of the United States
of America, and subject to the issuance by the Commission of an order declaring
the Registration Statement effective, we are of the opinion that the Shares
issued pursuant to the terms of the Agreement and Plan of Merger, dated as of
August 1, 1994 among the Company, Sterling Acquisition, Inc., American Business
Computer

Company ("ABCC") and the shareholders of ABCC, have been validly issued, and are
fully paid and nonassessable.

     We express no opinion as to the laws of any jurisdiction other than the 
State of Texas and, solely with respect to matters of corporate law, the State 
of Delaware.  You should be aware that we are not admitted to practice law in 
the State of Delaware.  Accordingly, any opinion herein as to the laws of the 
State of Delaware is based solely upon the latest generally available 
compilation of the statutes and case law of such state.

     We hereby consent to the filing of this opinion with the Commission as an 
exhibit to the Registration Statement and to the reference to our firm therein 
under the caption "Legal Matters".  In giving this consent, we do not hereby 
admit that we come within the category of persons whose consent is required 
under Section 7 of the Act or the rules and regulations of the Commission 
promulgated thereunder.


                                           Very truly yours,

                        Consent of Independent Auditors

We consent to the reference to our firm under the caption "Experts" in the
Registration Statement (Form S-3) pertaining to the registration of 306,513
shares of common stock of Sterling Software, Inc. and to the incorporation by
reference therein of our report dated November 15, 1993, with respect to the

     WHEREAS, the Sellers own all of the issued and outstanding common stock, no
par value, of the Company (the "Company Common"), which  shares constitute all
of the issued and outstanding capital stock of the Company;

     WHEREAS, Sterling owns all of the issued and outstanding shares of common
stock of Purchaser;

     WHEREAS, the respective boards of directors of Sterling, Purchaser and the
Company have deemed that a business combination between Purchaser and the

advisable and in the best interests of their respective corporations;

     WHEREAS, the Sellers, as the sole voting shareholders of the Company, and
Sterling, as the sole voting shareholder of Purchaser, have duly approved such
business combination; and

     WHEREAS, it is intended that such business combination shall qualify as a
reorganization within the meaning of Section 368 of the Internal Revenue Code of

accounted for as a "pooling of interests" for financial accounting purposes.

     NOW, THEREFORE, in consideration of the premises and the mutual agreements,
provisions and covenants herein contained, the sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

at the Effective Time (as defined in Section 1.2), Purchaser shall be merged
with and into the Company in accordance with this Agreement and the separate
corporate existence of Purchaser shall thereupon cease (the "Merger").  The

IV.  Representations, Warranties and Covenants of the Sellers.
     ---------------------------------------------------------

     Each Seller additionally, jointly and severally represents and warrants
that the following are true and correct as of the date hereof and will be true
and correct through the Closing Date as if made on that date and agrees as
follows:

     4.1  Ownership of the Stock.  Each Seller owns, beneficially and of record,
          ----------------------                                                
good and marketable title to the Company Common shown opposite his name on

for investment and not with a view to, or for resale in connection with, any
distribution and no other person has or will have any right to acquire any
beneficial interest therein.  Each Seller fully understands and agrees that he
must bear the economic risk of the acquisition of the Sterling Shares for an
indefinite period of time because the Sterling Shares have not been registered
under the Securities Act of 1933, as amended (the "Securities Act"), or under
the securities laws of any state or other jurisdiction and, therefore, cannot be
resold, pledged, assigned or otherwise disposed of unless the Sterling Shares
are subsequently registered for sale under the Securities Act and the applicable
securities laws of such states or unless an exemption from registration is
available.  Each of the Sellers has received a copy of the Sterling Annual
Report on Form 10-K for the fiscal year ended September 30, 1993, and all other
documents filed subsequent to September 30, 1993 under Sections 13(a), 13(c), 14
or 15(d) of the Exchange Act (including without limitation, its Form 10-Q for
the quarters ended December 31, 1993 and March 31, 1994 and its Proxy Statement
dated February 8, 1994), each in the form (excluding exhibits) filed with the
SEC (collectively, the "Reports").  Each of the Sellers agrees that (i) a
restrictive legend as provided in the form of Affiliate's Letter attached hereto
as Exhibit J will be placed on each certificate representing the Sterling Shares
and a notation shall be made in the appropriate records of Sterling indicating
that such shares are subject to restrictions on transfer, and (ii) each of the
Sellers has received and reviewed this Agreement and the Reports and other
documents referred to herein and has been given the opportunity to obtain any
additional information or documents and to ask questions and receive answers
about such documents.  Each of the Sellers has carefully reviewed and fully
understands the nature and risks of, and other considerations relating to, the
issuance of the Sterling Shares.  Each of the Sellers has received only the
Reports and the documents attached as exhibits hereto, and the other documents
that Sterling may have provided at the specific request of any of the Sellers,
and has received no other literature from Sterling.  Except as set forth in this
Agreement and the exhibits hereto, no representations or warranties have been
made to the Sellers by Sterling or by any person acting on behalf of Sterling
with respect to the business or financial condition of Sterling.

     4.4    Control of Related Businesses.  No Seller controls another business
            -----------------------------                                      
that is in the same or similar line of business as the Company or that has or is
engaged in transactions with the Company except transactions in the ordinary
course of business, and, since September 30, 1993, involving transactions of
less than $10,000 in the aggregate.

     4.5    Ownership of Sterling Shares.  No Seller, directly or indirectly,
            ----------------------------                                     
beneficially or of record, owns or has any ownership interest in Sterling Common
Stock (other than indirectly, through registered mutual funds over which the
Seller has no control or influence and which ownership interest constitutes less
than 1/2 of 1% of the total funds under management).

                                     -26-

     4.6  Transfers of Company Common.  There have been no transfers of the
          ---------------------------                                      
Company Common since inception of the Company.


V.   Representations and Warranties of Sterling and Purchaser.
     -------------------------------------------------------- 

     Sterling and Purchaser represent and warrant to the Company and the Sellers
that:

     5.1  Organization, Power.  Sterling and Purchaser are corporations duly
          -------------------                                               
organized, validly existing and in good standing under the laws of the States of

requisite corporate power and authority to enter into this Agreement and perform
its obligations hereunder.

     5.2  Authorization.  Each of Sterling and Purchaser has all requisite power
          -------------

delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by the Board of Directors of Sterling and the
sole shareholder and Board of Directors of Purchaser and no other corporate
proceedings on the part of either of them are necessary to authorize the
execution and delivery of this Agreement and the transactions contemplated
hereby.  This Agreement constitutes the legal, valid and binding obligation of
Sterling and Purchaser enforceable in accordance with its terms, except as (a)
enforceability hereof may be limited by bankruptcy, insolvency, reorganization
or moratorium or other similar laws affecting the enforcement of creditors'
rights generally and (b) the availability of equitable remedies may be limited
by equitable principles of general applicability.

     5.3  No Violation.  The execution, delivery and performance of this
          ------------                                                  
Agreement by Sterling and Purchaser and the consummation by it of the
transactions contemplated hereby do not require the consent, waiver, approval,
license or authorization of any Person which is not provided for in this
Agreement, do not violate, with or without the giving of notice or the passage
of time, any provision of law applicable to it or the corporate charter or by-
laws of Sterling or Purchaser and do not conflict with or result in a breach or
termination of any provision of, or constitute a default under, or result in the
creation of any lien, charge or encumbrance upon any of the property, assets or
capital stock of Sterling or Purchaser pursuant to, any mortgage, deed of trust,
indenture or other agreement, contract, commitment or instrument or any order,
judgment, decree, statute, regulation or any other restriction of any kind or
character to which Sterling or Purchaser is a party or by which Sterling or
Purchaser or any of its assets may be bound.

     5.4  Compliance with Laws.  Sterling has complied in all material respects
          --------------------                                                 
with, and is not in violation of in any material respect, any laws, rules,
regulations, orders or decrees applicable to Sterling or its business, contracts
or assets the noncompliance 

                                     -27-
<PAGE>
 
with or violation of which would have a material adverse effect on the business
and operations of Sterling and its subsidiaries taken as a whole. Sterling has
not received notice and has no knowledge of any violation by Sterling of any
applicable material foreign, federal, state, provincial, municipal, local or
foreign law, rule, regulation, order or decree, and is not aware of any
threatened claim of such a violation (including any investigations relating
thereto), the violation of which would have a material adverse effect on the
business and operations of Sterling and its subsidiaries taken as a whole.

     5.5  Sterling Shares.  When issued and delivered to Sellers pursuant to
          ---------------                                                   
this Agreement, the Sterling Shares will be validly issued, fully paid and
nonassessable.  The rights provided for under the Sterling Shares are identical
to those rights provided for under the other outstanding shares of the Sterling
Common Stock.

     5.6  Continuity.  Following the Merger, the Surviving Corporation, directly
          -----------                                                           
or through its subsidiaries, will continue the Company's historic business or
use a significant portion of the Company's historic business assets in its
business.


VI.  S Corporation Issues
     --------------------

     6.1  S Corporation.  The Company and the Sellers jointly and severally
          -------------                                                    
represent and warrant that the Company is now an S corporation under the Code
and has been an S corporation continuously since July 1, 1993.  The closing of
the transactions contemplated hereby will terminate the S status of the Company
effective with the Closing and require the filing of a tax return for the period
beginning January 1, 1994, and ending the day before the Closing Date (the
"Short Tax Period").  The Company shall close its books as of the end of the
Short Tax Period pursuant to Section 1362(e)(6)(D) of the Code and compute
taxable income or taxable loss for the Short Tax Period on the basis of the
permanent books and records (including workpapers) of the Company.  The Company
shall prepare the necessary tax return information, in accordance with its
customary accounting procedures, for the Short Tax Period in accordance with the
Subchapter S requirements of the Code and provide such information to the
Sellers.  The Sellers shall pay the federal and state income tax, if any, for
the Short Tax Period, including but not limited to any such taxes payable by the
Company for the Short Tax Period.  Notwithstanding the termination of the
Shareholders Agreement contemplated by Section 10.10 hereof, as contemplated by
such agreement, the Company shall distribute cash to the Sellers in an amount
equal all of their federal, state and local income taxes for the Short Tax
Period on the income that passes through to the Sellers as a result of the
Company's status as an S corporation, reduced by any tax benefits produced by
losses, deductions and credits that pass through to the Sellers as a result of
the Company's status as an S corporation.  Such distribution shall be in the
form of a dividend from the Company to the Sellers, declared prior to the
Closing, and shall be made on or after the Closing Date 

                                     -28-
<PAGE>
 
promptly following the Company's determination of the amount of such taxes and
in any event within sixty (60) days of the date it is declared.

     6.2  Amendment of Returns.  If the Sellers become aware that the returns of
          --------------------                                                  
the Company for any period when the Company was an S corporation may be amended
to provide a tax refund to the Sellers, the Company, at the expense of the
Sellers, shall prepare and file such amendments to the return as may be
necessary, provided, however, that the Company shall not be required to file any
such amendment that would, as determined by Sterling in its sole and absolute
discretion, have an adverse tax effect on the Company for periods prior to or
subsequent to the Closing.  The Company has no obligation with respect to
pursuing such refund other than to prepare and file amendments to such returns
pursuant to this Section 6.2.

     6.3  Audits.  In the event of any audit by the Internal Revenue Service
          ------                                                            
(the "IRS") or other taxing authority of the tax liability of the Company or the
Sellers for the periods during which the Company was an S corporation, the
Company shall notify the Sellers immediately of such audit or threatened audit.
The Company at the expense of the Sellers shall respond to the audit and shall
keep the Sellers informed of any issues raised by the taxing authority involved.
The Sellers shall have the sole right to settle or contest any deficiency
proposed by the IRS or such other authority; provided, however, that the Sellers
shall not settle any deficiency without the consent of the Company if such
settlement would have an adverse tax effect on the Company for periods
subsequent to the Closing.  The Company shall provide each Seller with access to
its books and records, and cooperate with the Sellers, to enable them to contest
any such deficiency.  In the event that the settlement or other determination of
any dispute results (i) in a tax benefit to the Company for a taxable period
other than the period when the Company was an S corporation by reducing the tax
liability of the Company or a corporation in its affiliated group and (ii)  a
tax detriment to the Sellers, the amount of such reduction in tax liability
shall be deducted from any liability of the Sellers under Section 11.1 hereof
arising out of claims for the breach by the Sellers of the representations set
forth in Section 3.8 hereof.  Any refunds of income taxes paid by the Sellers
for the periods when the Company was an S corporation shall belong to the
Sellers.

     authorities and parties to contracts, agreements, licenses or other
     instruments relating to the business as may be required in order to enable
     the Company and the Sellers to perform their obligations hereunder, except

     will provide to Purchaser such other information as Purchaser shall
     request.  With the consent of the Company, not to be unreasonably withheld,

     Company as Purchaser shall reasonably request.

          (d) Prior to the Closing the Sellers shall not sell or otherwise

          (f) Except as otherwise provided herein, each party hereto shall pay
     all of its own fees and expenses incident to the negotiation, preparation,
     execution and performance of this Agreement, including the fees and
     expenses of their respective counsel, accountants, investment bankers and
     other experts, provided that any such fees and expenses of the Company in
     excess of $25,000 shall be paid by the Sellers. The Sellers shall pay any
     sales, real estate or other transfer, stamp or similar taxes incurred with
     respect to the Agreement and the transactions contemplated hereby (e.g.,
     the Merger). Sterling and Purchaser shall each be responsible for their own
     gains and income taxes and Sellers shall be responsible for the Company's
     and their own gains and income taxes incurred in connection with the
     transactions contemplated hereby. Anything in this Agreement to the

     built in gain tax pursuant to Section 1374 of the Code payable by the
     Company or Purchaser as a result of actions occurring on or after the

          (g) Sterling and Purchaser shall take all actions necessary to (i)

     continued favorable tax qualification of the Sterling Plan and the Company
     Plan.

          (h) No news release or other public announcement pertaining in any way
     to the transactions contemplated by this Agreement shall be made by
     Purchaser without the prior consent of the Sellers, or by the Company or
     the Sellers, without the prior consent of Sterling, unless in the opinion
     of counsel to either Sterling and Purchaser or the Sellers and the Company,
     as the case may be, such release or announcement is required by law
     (including federal securities laws) or the rules of the New York Stock
     Exchange; provided that the obligations of 

                                     -32-
<PAGE>
 
     Sterling and Purchaser under this Section 7.2 (h) shall expire one (1)
     month after the Closing Date.

     7.3  Registration Rights.
          ------------------- 

          (a)  Sterling will use reasonable efforts to file a "shelf"
     registration statement with the Securities and Exchange Commission (the
     "SEC"), as soon as practicable after the Closing, covering the registration
     of the sale of the Sterling Shares by the Sellers from time to time in the
     open market, and will use reasonable efforts to cause such registration
     statement to be declared effective by the SEC.  Sterling currently believes
     that its reasonable efforts will result in such registration statement
     being declared effective by the SEC. Sterling shall bear all expenses
     related to such registration statement.

          (b) In connection with the disposition of the Sterling Shares under
     the registration statement, in order for the Sellers to dispose of Sterling
     Shares with a prospectus that is part of the registration statement, the
     Sellers must give Sterling written notice of their intention to sell any of
     the Sterling Shares at least two (2) but not more than twenty (20) business
     days prior to the date of the proposed sales which notice shall include the
     number of shares proposed to be disposed, whether the shares are to be sold
     in an underwritten offering and the time period during the thirty (30) days
     following the date of such notice during which the shares may be disposed
     (the "Sale Period"), and the Sellers agree that, during each Sale Period,
     they shall not deliver any prospectus that is part of the registration
     statement in connection with any disposition of Sterling Shares during any
     period of time when, but only so long as, Sterling, after receipt of the
     notice set forth above, notifies the Sellers (a "Delay Notice") that
     Sterling is in possession of material non-public information that, in the
     exercise of its reasonable judgment, would be required to be disclosed in
     the registration statement (or in the amendment, or post-effective
     amendment thereto) in order to comply with SEC requirements, which material
     information may relate, including, without limitation, to a financing
     project or a pending acquisition, merger or other material corporate
     reorganization or transaction to which Sterling is or is expected to be a
     party; provided that Sterling shall advise the Sellers in writing as soon
     as any such delay is no longer applicable; provided, further, that the
     Sellers shall only be prevented from disposing of Sterling Shares with a
     prospectus under the registration statement for up to 90 consecutive days
     (a "Delay Period") following the receipt of a Delay Notice and any two
     Delay Periods must be at least fifteen (15) days apart during which time
     the Sellers shall be permitted to dispose of Sterling Shares with a
     prospectus under the registration statement.

          (c)  Sterling will:

                                     -33-
<PAGE>
 
               (i) use reasonable efforts to keep such registration statement
          effective until the second anniversary of the Closing Date; provided,
          however, Sterling may delay or suspend such registration at any time
          for so long as, in the reasonable business judgment of Sterling, the
          financial statements or other information necessary to keep such
          registration statement effective cannot be produced without undue
          expense or burden or otherwise are not available;

               (ii) furnish to each Seller a conformed copy of such registration
          statement and of each amendment or supplement thereto, and such number
          of copies of the prospectus contained in such registration statement
          and any other prospectus filed under Rule 424 under the Securities Act
          as the Sellers may reasonably request in order to facilitate the
          distribution of the Sterling Shares, in conformity with the
          requirements of the Securities Act;

               (iii)  use reasonable efforts to register or qualify the Sterling
          Shares covered by such registration statement under such other
          securities or blue sky laws of such states as shall be reasonably
          appropriate for the distribution of securities covered by such
          registration, except that Sterling shall not for any such purpose be
          required to qualify generally to do business as a foreign corporation
          in any jurisdiction wherein it would not but for the requirements of
          this Section 7.3(c)(iii) be obligated to be so qualified or to consent
          to general service of process in any such jurisdiction;

               (iv) notify each Seller at any time when a prospectus relating
          thereto is required to be delivered under the Securities Act, upon
          discovery that, or upon the happening of any event as a result of
          which, the prospectus included in such registration statement, as then
          in effect, includes an untrue statement of a material fact or omits to
          state any material fact required to be stated therein or necessary to
          make the statements therein not misleading in light of the
          circumstances under which they were made, and at the request of any
          Seller promptly prepare and furnish to such Seller a reasonable number
          of copies of a supplement to or an amendment of such prospectus as may
          be necessary so that, as thereafter delivered to the purchasers of
          such securities, such prospectus shall not include an untrue statement
          of a material fact or omit to state a material fact required to be
          stated therein or necessary to make the statements therein not
          misleading in the light of the circumstances under which they were
          made; and

                                     -34-
<PAGE>
 
               (v) otherwise use reasonable efforts to comply with all
          applicable rules and regulations of the SEC.

     Each Seller shall, upon receipt of any notice from Sterling of the
     happening of any event of the kind described in Section 7.3(c)(i) or
     7.3(c)(iv), forthwith discontinue such person's disposition of Sterling
     Shares pursuant to the registration statement until such holder's receipt
     of the copies of the supplemented or amended prospectus contemplated by
     Section 7.3(c)(i) or 7.3(c)(iv) and, if so directed by Sterling, shall
     deliver to Sterling all copies, other than permanent file copies, then in
     such holder's possession of the prospectus relating to such Seller
     Securities current at the time of receipt of such notice.

          (d) If so requested in writing by a managing underwriter in an
     offering by Sterling, neither Seller shall effect any sale or other
     disposition of any Sterling Common during the seven days prior to and the
     90 days after any registration related to such offering.

          (e) It shall be a condition precedent to the obligations of Sterling
     to file or keep effective any registration pursuant to this Section 7.3
     that each Seller shall furnish to Sterling such information regarding
     itself, the Sterling Shares held by it and its proposed disposition thereof
     as Sterling shall reasonably request.

          (f) To the extent permitted by law, each Seller requesting or joining
     in a registration pursuant to this Section 7.3 shall indemnify Sterling and
     its officers and directors and its legal counsel, and each Person if any,
     who controls any thereof within the meaning of Section 15 of the Securities
     Act or Section 20 of the Securities Exchange Act of 1934, as amended, and
     their respective successors against all claims, losses, damages and
     liabilities, joint or several, or actions in respect thereof, arising out
     of or based on any untrue statement (or alleged untrue statement) of a
     material fact contained in any prospectus, offering circular or other
     document incident to any registration, qualification or compliance (or in
     any related registration statement, notification or the like) or any
     omission (or alleged omission) to state therein a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading in the light of the circumstances in which they were made and
     will reimburse Sterling and each other Person indemnified pursuant to this
     Section 7.3 (f) for any legal and any other expenses reasonably incurred in
     connection with investigating or defending any such claim, loss, damage,
     liability or action; provided, however, that this Section 7.3 (f) shall
     apply only if (and only to the extent that) such statement or omission was
     made in reliance upon and in conformity with information (including,
     without limitation, negative responses to inquiries) furnished to Sterling
     by the Sellers and designated to be specifically for use therein.

                                     -35-
<PAGE>
 
          (g) Following the Closing, Sterling shall prepare and submit to the
     New York Stock Exchange ("NYSE") a listing application covering the

     contemplated under this Section 7.3 becomes effective.

after the Closing Date; provided, however, that if Sterling shall notify the
Sellers or if the Sellers shall notify Sterling on or before the expiration of
such one (1) year period of any asserted inaccuracy or other breach of any such

respect to such asserted claim shall survive until the final disposition of such

Article XI of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Article XI, notify the indemnifying party in
writing of the claim or the commencement of that action, provided that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to the indemnified party except for fees or expenses
unreasonably incurred in connection with such claim prior to such notice or to
the extent such failure directly prejudices the indemnifying party with respect
to such claim.  If any such claim shall be brought against an indemnified party,
and it shall notify the indemnifying party thereof, the indemnifying party shall
be entitled to participate therein, and to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party, and to settle and
compromise any such claim or action; provided, however, that 

                                     -41-
<PAGE>
 
such settlement or compromise shall be effected only with the consent of the
indemnified party, which consent shall not be unreasonably withheld (it being
understood that in considering whether or not to give such consent, the
indemnified party is entitled to assess the implications of such settlement or
compromise on the future conduct of its or its Affiliates' business activities).
After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Article XI for any legal
or other expense subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation; provided,
however, that the indemnified party shall have the right to employ counsel to
represent it if, in the indemnified party's reasonable judgment, it is advisable
for the indemnified party to be represented by separate counsel, and in that
event the fees and expenses of such separate counsel shall be paid by the
indemnifying party. Purchaser and the Sellers each agree to render to each other
such assistance as may reasonably be requested in order to insure the proper and
adequate defense of any such claim or proceeding.

     11.6 Certain Limitations.  Notwithstanding any other provision of this
          -------------------

be required to indemnify the Sellers or any other indemnitee for any loss or
