As an attorney representing your client, your task is to compare the template text and the contract text provided and identify any changes that may impact the agreement or the involved parties. Specifically, you need to analyze the legal implications and considerations of the word 'subcontractors' when it appears in the changed text. Instead of focusing solely on the addition or removal of the letters 'or,' provide a comprehensive analysis based on the complete word 'subcontractors.' Classify the changes as either "minor_change" or "major_change."
Please provide the changed text alone as a separate paragraph under the "Changed:" subheading, and the analysis of the changes as a separate paragraph under the "Analysis:" subheading. At the end, add ~!~ and classification like ~!~minor_change or ~!~major_change.
EXAMPLES -
1.
Contract text:
Verify identification credentials including Social Security number, driver’s license, educational credentials, employment history, home address, and citizenship indicia;
In connection with providing access to a customer’s facilities or systems, comply with any additional investigation or screening requirements required by such customer as communicated in advance; test for use of illicit drugs including opiates, cocaine, cannabinoids, amphetamines, and phencyclidine.
Template text:
Verify identification credentials including Social Security number, driver’s license, educational credentials, employment history, home address, and citizenship indicia.
In connection with providing access to a customer’s facilities or systems, comply with any additional investigation or screening requirements required by such customer as communicated in advance. Test for use of illicit drugs including opiates, cocaine, cannabinoids, amphetamines, and phencyclidine.
Differences Observed -
Changed: "When (i) the customer or end user is a federal, state, or local government entity"
Analysis:
A new sentence is added: "When (i) the customer or end user is a federal, state, or local government entity" in the template text. This clause specifies a condition under which the drug testing requirement applies. In the template text, this condition is excluded, meaning that the drug testing requirement would apply regardless of whether the customer or end user is a government entity. This could potentially change the scope and applicability of the drug testing provision.~!~major_change
2.
Contract text:
Perform a criminal background check to determine, in the counties, states, and federal court districts where the candidate has lived, worked, or attended school in the previous ten years, whether the candidate has been: (1) convicted of any felony; (2) convicted of a misdemeanor involving violence, theft, computer crimes, fraud, financial crimes, drug distribution, unlawful possession or use of a dangerous weapon, or sexual misconduct; or, (3) listed on any government registry as a sex offender (together, “Conviction”); and in connection with providing access to a customer’s facilities or systems, comply with any additional investigation or screening requirements required by such customer as communicated in advance.

In connection with providing access to a customer’s facilities or systems, comply with any additional investigation or screening requirements required by such customer as communicated in advance.
Differences Observed -
Changed: "and"
Analysis:
The contract text includes the word "and," which isn't in the template. This could potentially change the interpretation of the agreement, as it could be read as each clause being a separate requirement, rather than a list of requirements.~!~major_change
3.
Contract text:
The service provider may not assign, delegate, or otherwise transfer its rights or obligations under this Agreement, voluntarily or involuntarily, without the prior written consent of the other party except that the service provider may delegate certain obligations hereunder to its subcontractors as contemplated by this Agreement. Any attempted assignment, delegation, or transfer not consented to in writing will be void. Notwithstanding the foregoing, with notice to the other party, either party may assign this Agreement, in whole or in part, to any affiliate, successor-in-interest or without securing the consent of the other party. Any assignment of money will be void if (i) the assignor fails to give the non-assigning party at least thirty (30) days prior written notice, or (ii) the assignment purports to impose upon the non-assigning party additional costs or obligations in addition to the payment of such money, or (iii) the assignment purports to preclude the other party from dealing solely and directly with the service provider in all matters pertaining to this Agreement. This Agreement binds and benefits both parties and their permitted successors and assigns.

This Agreement binds and benefits both parties and their permitted successors and assigns.
Differences Observed -
Changed: "Subcontractors"
Analysis: The contract text includes the word "Subcontractors" instead of "Subcontracts" as in the template. This change could potentially alter the meaning of the agreement as it specifies a different entity (Subcontractors vs Subcontracts). However, given the context, it seems likely that this is a typographical error in the template text, and the intended meaning remains the same.~!~minor_change
4.
Contract text:
This AGREEMENT is entered into between [Company Name], a [State] corporation, which sometimes does business as [DBA Name], (“Company”) and [Other Party Name], a [State] LLC (“Solution Provider” or “SP”). The company and solution provider may be referred to collectively as the “Parties” or individually as a “Party.”
Template text:
ALLIANCE PROGRAM AGREEMENT This AGREEMENT is entered into between [Company Name], a [State] corporation, which sometimes does business as [DBA Name], (“Company”) and ________________________, a __________ corporation (“Solution Provider” or “SP”). The company and solution provider may be referred to collectively as the “Parties” or individually as a “Party.”
Differences Observed -
Changed:"[Other Party Name], a [State] LLC"
Analysis: The contract text includes the specific name of the corporation "[Other Party Name], a [State] LLC" instead of a placeholder as in the template. This is a minor change as it is expected that the specific name of the corporation would be filled in the actual contract.~!~minor_change
